The type of this argument has -been changed from int to unsigned int. A new function, FtpSizeLong, -returns the remote file's size as an unsigned long long. - -8) The second argument to the callback function has been changed from -an int to an unsigned long long. This value contains the number of -bytes transferred so far. - -9) The library version 1 interface compatability macros have been -removed from the header file. If your application needs them, extract -them from the old header file. - -10) The usage information in qftp.c has been corrected. - -11) qftp now accepts a '-s ' option to send as a SITE -command. - -12) qftp progress reports now use floating point calculation so that -large numbers don't cause overflows. If the remote server does not -support the SIZE command, qftp will update every 32KB. - -13) A new type-safe method is provided to establish a callback -function. Put the details of when the function should be called into -a FtpCallbackOptions structure and pass it to FtpSetCallback(). To -remove a callback, call FtpClearCallback(). - -14) Updated html documentation. - -Changes from V3.1 to V3.1-1 - -1) Delay setting the control handle pointer in the data handle until -after the transfer request has received a positive acknowledgement. -This should resolve problems calling FtpClose() on the data handle -when the transfer is rejected. - -2) Fix error handling in FtpRead() and FtpWrite(). - -3) Return status of transfer from FtpXfer() instead of status of -FtpClose(). - -4) Allow FtpClose() to be called on a control handle. This should be -used instead of FtpQuit() in cases where a transfer was interrupted. -FtpQuit() would attempt to send a 'QUIT' command and wait for a -response but this would be out of sync after an interrupt. - -5) The idle callback routine was not being set in the data handle if -the user didn't set FTPLIB_IDLETIME. Fixed this so it would get set -up if either this or FTPLIB_CALLBACKBYTES was set. - -6) Open local files in binary mode when appropriate. This is -necessary on some systems like NT and VMS. - -7) Added a wildcard mode to qftp for wildcard retrieves. Argument -after '-w' is treated as a remote wildcard file specification. - -Changes from 12/2/97 (V3) to .... (V3.1) - -1) Added FtpPwd(), FtpSysType(), FtpCDUp(), FtpSize() and FtpModDate(). - -2) Fixed bug in FtpClose() - It wasn't waiting for the '226 Transfer -Complete' since it didn't have access to the control connection. A -pointer to it is now kept in the data connection. - -3) Fixed bug in FtpClose() - The data connection wasn't being freed. This -could have resulted in memory leaks. - -4) Allow runtime selection of connection mode (PORT/PASV) with default set -at compile time. - -5) Added support for a user callback routine which can get called after a -user specified number of bytes are transferred or after waiting for data -on a socket for a user specified time period. - -6) Add FtpOptions() which allows changing connection options. Options -include connection mode, callback routine, and parameters regarding when -the user's callback routine gets called. - -7) Added checks to make sure strcpy()/sprintf()/etc. wouldn't write past -end of buffers. - -8) Modified build procedure to create a shared library. - -9) Added install option to makefile which installs under /usr/local. - -10) Modified qftp to use new interface. - -11) Modified qftp to log progress every 10% of file or every time data -is delayd by 1 second if -v setting is not zero. - -12) Modified qftp to use fgets() instead of gets(). - ------------------------------------------------------------------------- - -Changes from 3/15/97 to 12/2/97 - -1) FtpLastResponse() returns NULL if passed a NULL pointer. - -2) Added 'const' keyword on appropriate function arguments. - -3) First attempt to translate passed host string as an IP address in dot - notation by passing it to inet_addr(). If this fails, pass the string - to gethostbyname(). Apparently, some versions of gethostbyname() will - parse the translation of a dot notation address for you. One user - reports he knows of at least one that does not. In any case, it's the - right thing to do. - -4) Added protection from double inclusion to header file. Also added - 'extern "C"' for C++. - -5) Made sure qftp was passed two arguments before examining the second - one. - -6) Made sure all commands to the server were in upper case. I've been - told that some servers require this. - -7) Attempt to handle login to accounts with no passwords. - -8) Added common data transfer routines so that ascii mode transfers would - be handled properly in all cases. Also, exposed these routines for - user programs to call. There's now FtpAccess() to open a remote file - or directory, FtpRead() and FtpWrite() to pass data, and FtpClose() to - terminate the data connection. - -9) Added 'list' command to qftp to perform a terse directory (names - only). This could be piped into another copy of qftp to retrieve the - files. - -10) ftplib.c and ftplib.h are now covered by the LGPL instead of the GPL. - Feel free to send me a complementary copy of anything you develop - commercially with my libraries. All other programs are still covered - by the GPL. - -11) Added ability to specify a different port number than the default by - appending a colon and the desired port number to the remote host name - (e.g., remote.host.name:500 would connect to port remote.host.name on - port 500). - ------------------------------------------------------------------------- - -Changes from 8/31/96 version to 3/15/97 version - -1) Added copyright information to sources. - -2) Changed from 'port' to 'pasv' which I'm told will allow the routines - to work from behind a firewall. It's also a lot simpler and cleaner - than all that code to setup and accept a connect from the server. - -3) Added delete (ftprm) support to qftp.c. - -4) Modified qftp to allow use without a softlink by passing the ftp - command as the first argument. - -5) Added netbuf argument to all calls to eliminate static storage and - allow multiple simultaneous connections. - -6) Renamed routines from ftp*() to Ftp*() to avoid problems with existing - programs. Added macros in libftp.h to support old interface. Renamed - ftpOpen() to FtpConnect(). diff --git a/deps/ftplib-4.0-1/LICENSE b/deps/ftplib-4.0-1/LICENSE deleted file mode 100644 index 1a630a2..0000000 --- a/deps/ftplib-4.0-1/LICENSE +++ /dev/null @@ -1,171 +0,0 @@ -Artistic License 2.0 - -Copyright (c) 2000-2006, The Perl Foundation. - -Everyone is permitted to copy and distribute verbatim copies of this -license document, but changing it is not allowed.

INTRODUCTION - - The objectives of FTP are 1) to promote sharing of files (computer - programs and/or data), 2) to encourage indirect or implicit (via - programs) use of remote computers, 3) to shield a user from - variations in file storage systems among hosts, and 4) to transfer - data reliably and efficiently. FTP, though usable directly by a user - at a terminal, is designed mainly for use by programs. - - The attempt in this specification is to satisfy the diverse needs of - users of maxi-hosts, mini-hosts, personal workstations, and TACs, - with a simple, and easily implemented protocol design. - - This paper assumes knowledge of the Transmission Control Protocol - (TCP) [2] and the Telnet Protocol [3].

HISTORY - - FTP has had a long evolution over the years. Appendix III is a - chronological compilation of Request for Comments documents - relating to FTP. These include the first proposed file transfer - mechanisms in 1971 that were developed for implementation on hosts - at M.I.T. (RFC 114), plus comments and discussion in RFC 141. - - RFC 172 provided a user-level oriented protocol for file transfer - between host computers (including terminal IMPs). A revision of - this as RFC 265, restated FTP for additional review, while RFC 281 - suggested further changes. The use of a "Set Data Type" - transaction was proposed in RFC 294 in January 1982. - - RFC 354 obsoleted RFCs 264 and 265. The File Transfer Protocol - was now defined as a protocol for file transfer between HOSTs on - the ARPANET, with the primary function of FTP defined as - transfering files efficiently and reliably among hosts and - allowing the convenient use of remote file storage capabilities. - RFC 385 further commented on errors, emphasis points, and - additions to the protocol, while RFC 414 provided a status report - on the working server and user FTPs. RFC 430, issued in 1973, - (among other RFCs too numerous to mention) presented further - comments on FTP. Finally, an "official" FTP document was - published as RFC 454. - - By July 1973, considerable changes from the last versions of FTP - were made, but the general structure remained the same. RFC 542 - was published as a new "official" specification to reflect these - changes. However, many implementations based on the older - specification were not updated. - - In 1974, RFCs 607 and 614 continued comments on FTP. RFC 624 - proposed further design changes and minor modifications. In 1975, - RFC 686 entitled, "Leaving Well Enough Alone", discussed the - differences between all of the early and later versions of FTP. - RFC 691 presented a minor revision of RFC 686, regarding the - subject of print files. - - Motivated by the transition from the NCP to the TCP as the - underlying protocol, a phoenix was born out of all of the above - efforts in RFC 765 as the specification of FTP for use on TCP. - - This current edition of the FTP specification is intended to - correct some minor documentation errors, to improve the - explanation of some protocol features, and to add some new - optional commands. - - -Postel & Reynolds [Page 2] - - - -RFC 959 October 1985 -File Transfer Protocol - - - In particular, the following new optional commands are included in - this edition of the specification: - - CDUP - Change to Parent Directory - - SMNT - Structure Mount - - STOU - Store Unique - - RMD - Remove Directory - - MKD - Make Directory - - PWD - Print Directory - - SYST - System - - This specification is compatible with the previous edition. A - program implemented in conformance to the previous specification - should automatically be in conformance to this specification. - - 2.2. TERMINOLOGY - - ASCII - - The ASCII character set is as defined in the ARPA-Internet - Protocol Handbook. In FTP, ASCII characters are defined to be - the lower half of an eight-bit code set (i.e., the most - significant bit is zero). - - access controls - - Access controls define users' access privileges to the use of a - system, and to the files in that system. Access controls are - necessary to prevent unauthorized or accidental use of files. - It is the prerogative of a server-FTP process to invoke access - controls. - - byte size - - There are two byte sizes of interest in FTP: the logical byte - size of the file, and the transfer byte size used for the - transmission of the data. The transfer byte size is always 8 - bits. The transfer byte size is not necessarily the byte size - in which data is to be stored in a system, nor the logical byte - size for interpretation of the structure of the data. - - - -Postel & Reynolds [Page 3] - - - -RFC 959 October 1985 -File Transfer Protocol - - - control connection - - The communication path between the USER-PI and SERVER-PI for - the exchange of commands and replies. This connection follows - the Telnet Protocol. - - data connection - - A full duplex connection over which data is transferred, in a - specified mode and type. The data transferred may be a part of - a file, an entire file or a number of files. The path may be - between a server-DTP and a user-DTP, or between two - server-DTPs. - - data port - - The passive data transfer process "listens" on the data port - for a connection from the active transfer process in order to - open the data connection. - - DTP - - The data transfer process establishes and manages the data - connection. The DTP can be passive or active. - - End-of-Line - - The end-of-line sequence defines the separation of printing - lines. The sequence is Carriage Return, followed by Line Feed. - - EOF - - The end-of-file condition that defines the end of a file being - transferred. - - EOR - - The end-of-record condition that defines the end of a record - being transferred. - - error recovery - - A procedure that allows a user to recover from certain errors - such as failure of either host system or transfer process. In - FTP, error recovery may involve restarting a file transfer at a - given checkpoint. - - - -Postel & Reynolds [Page 4] - - - -RFC 959 October 1985 -File Transfer Protocol - - - FTP commands - - A set of commands that comprise the control information flowing - from the user-FTP to the server-FTP process. - - file - - An ordered set of computer data (including programs), of - arbitrary length, uniquely identified by a pathname. - - mode - - The mode in which data is to be transferred via the data - connection. The mode defines the data format during transfer - including EOR and EOF. The transfer modes defined in FTP are - described in the Section on Transmission Modes. - - NVT - - The Network Virtual Terminal as defined in the Telnet Protocol. - - NVFS - - The Network Virtual File System. A concept which defines a - standard network file system with standard commands and - pathname conventions. - - page - - A file may be structured as a set of independent parts called - pages. FTP supports the transmission of discontinuous files as - independent indexed pages. - - pathname - - Pathname is defined to be the character string which must be - input to a file system by a user in order to identify a file. - Pathname normally contains device and/or directory names, and - file name specification. FTP does not yet specify a standard - pathname convention. Each user must follow the file naming - conventions of the file systems involved in the transfer. - - PI - - The protocol interpreter. The user and server sides of the - protocol have distinct roles implemented in a user-PI and a - server-PI. - - -Postel & Reynolds [Page 5] - - - -RFC 959 October 1985 -File Transfer Protocol - - - record - - A sequential file may be structured as a number of contiguous - parts called records. Record structures are supported by FTP - but a file need not have record structure. - - reply - - A reply is an acknowledgment (positive or negative) sent from - server to user via the control connection in response to FTP - commands. The general form of a reply is a completion code - (including error codes) followed by a text string. The codes - are for use by programs and the text is usually intended for - human users. - - server-DTP - - The data transfer process, in its normal "active" state, - establishes the data connection with the "listening" data port. - It sets up parameters for transfer and storage, and transfers - data on command from its PI. The DTP can be placed in a - "passive" state to listen for, rather than initiate a - connection on the data port. - - server-FTP process - - A process or set of processes which perform the function of - file transfer in cooperation with a user-FTP process and, - possibly, another server. The functions consist of a protocol - interpreter (PI) and a data transfer process (DTP). - - server-PI - - The server protocol interpreter "listens" on Port L for a - connection from a user-PI and establishes a control - communication connection. It receives standard FTP commands - from the user-PI, sends replies, and governs the server-DTP. - - type - - The data representation type used for data transfer and - storage. Type implies certain transformations between the time - of data storage and data transfer. The representation types - defined in FTP are described in the Section on Establishing - Data Connections. - - - - -Postel & Reynolds [Page 6] - - - -RFC 959 October 1985 -File Transfer Protocol - - - user - - A person or a process on behalf of a person wishing to obtain - file transfer service.

THE FTP MODEL - - With the above definitions in mind, the following model (shown in - Figure 1) may be diagrammed for an FTP service. - - ------------- - |/---------\| - || User || -------- - ||Interface|<--->| User | - |\----^----/| -------- - ---------- | | | - |/------\| FTP Commands |/----V----\| - ||Server|<---------------->| User || - || PI || FTP Replies || PI || - |\--^---/| |\----^----/| - | | | | | | - -------- |/--V---\| Data |/----V----\| -------- - | File |<--->|Server|<---------------->| User |<--->| File | - |System| || DTP || Connection || DTP || |System| - -------- |\------/| |\---------/| -------- - ---------- ------------- - - Server-FTP USER-FTP - - NOTES: 1. The data connection may be used in either direction. - 2. The data connection need not exist all of the time. - - Figure 1 Model for FTP Use - - In the model described in Figure 1, the user-protocol interpreter - initiates the control connection. The control connection follows - the Telnet protocol. At the initiation of the user, standard FTP - commands are generated by the user-PI and transmitted to the - server process via the control connection. (The user may - establish a direct control connection to the server-FTP, from a - TAC terminal for example, and generate standard FTP commands - independently, bypassing the user-FTP process.) Standard replies - are sent from the server-PI to the user-PI over the control - connection in response to the commands. - - The FTP commands specify the parameters for the data connection - (data port, transfer mode, representation type, and structure) and - the nature of file system operation (store, retrieve, append, - delete, etc.). The user-DTP or its designate should "listen" on - the specified data port, and the server initiate the data - connection and data transfer in accordance with the specified - parameters. It should be noted that the data port need not be in - - -Postel & Reynolds [Page 8] - - - -RFC 959 October 1985 -File Transfer Protocol - - - the same host that initiates the FTP commands via the control - connection, but the user or the user-FTP process must ensure a - "listen" on the specified data port. It ought to also be noted - that the data connection may be used for simultaneous sending and - receiving. - - In another situation a user might wish to transfer files between - two hosts, neither of which is a local host. The user sets up - control connections to the two servers and then arranges for a - data connection between them. In this manner, control information - is passed to the user-PI but data is transferred between the - server data transfer processes. Following is a model of this - server-server interaction. - - - Control ------------ Control - ---------->| User-FTP |<----------- - | | User-PI | | - | | "C" | | - V ------------ V - -------------- -------------- - | Server-FTP | Data Connection | Server-FTP | - | "A" |<---------------------->| "B" | - -------------- Port (A) Port (B) -------------- - - - Figure 2 - - The protocol requires that the control connections be open while - data transfer is in progress. It is the responsibility of the - user to request the closing of the control connections when - finished using the FTP service, while it is the server who takes - the action. The server may abort data transfer if the control - connections are closed without command. - - The Relationship between FTP and Telnet: - - The FTP uses the Telnet protocol on the control connection. - This can be achieved in two ways: first, the user-PI or the - server-PI may implement the rules of the Telnet Protocol - directly in their own procedures; or, second, the user-PI or - the server-PI may make use of the existing Telnet module in the - system. - - Ease of implementaion, sharing code, and modular programming - argue for the second approach. Efficiency and independence - - - -Postel & Reynolds [Page 9] - - - -RFC 959 October 1985 -File Transfer Protocol - - - argue for the first approach. In practice, FTP relies on very - little of the Telnet Protocol, so the first approach does not - necessarily involve a large amount of code. - -3. DATA TRANSFER FUNCTIONS - - Files are transferred only via the data connection. The control - connection is used for the transfer of commands, which describe the - functions to be performed, and the replies to these commands (see the - Section on FTP Replies). Several commands are concerned with the - transfer of data between hosts. These data transfer commands include - the MODE command which specify how the bits of the data are to be - transmitted, and the STRUcture and TYPE commands, which are used to - define the way in which the data are to be represented. The - transmission and representation are basically independent but the - "Stream" transmission mode is dependent on the file structure - attribute and if "Compressed" transmission mode is used, the nature - of the filler byte depends on the representation type. - - 3.1. DATA REPRESENTATION AND STORAGE - - Data is transferred from a storage device in the sending host to a - storage device in the receiving host. Often it is necessary to - perform certain transformations on the data because data storage - representations in the two systems are different. For example, - NVT-ASCII has different data storage representations in different - systems. DEC TOPS-20s's generally store NVT-ASCII as five 7-bit - ASCII characters, left-justified in a 36-bit word. IBM Mainframe's - store NVT-ASCII as 8-bit EBCDIC codes. Multics stores NVT-ASCII - as four 9-bit characters in a 36-bit word. It is desirable to - convert characters into the standard NVT-ASCII representation when - transmitting text between dissimilar systems. The sending and - receiving sites would have to perform the necessary - transformations between the standard representation and their - internal representations. - - A different problem in representation arises when transmitting - binary data (not character codes) between host systems with - different word lengths. It is not always clear how the sender - should send data, and the receiver store it. For example, when - transmitting 32-bit bytes from a 32-bit word-length system to a - 36-bit word-length system, it may be desirable (for reasons of - efficiency and usefulness) to store the 32-bit bytes - right-justified in a 36-bit word in the latter system. In any - case, the user should have the option of specifying data - representation and transformation functions. It should be noted - - - -Postel & Reynolds [Page 10] - - - -RFC 959 October 1985 -File Transfer Protocol - - - that FTP provides for very limited data type representations. - Transformations desired beyond this limited capability should be - performed by the user directly. - - 3.1.1. DATA TYPES - - Data representations are handled in FTP by a user specifying a - representation type. This type may implicitly (as in ASCII or - EBCDIC) or explicitly (as in Local byte) define a byte size for - interpretation which is referred to as the "logical byte size." - Note that this has nothing to do with the byte size used for - transmission over the data connection, called the "transfer - byte size", and the two should not be confused. For example, - NVT-ASCII has a logical byte size of 8 bits. If the type is - Local byte, then the TYPE command has an obligatory second - parameter specifying the logical byte size. The transfer byte - size is always 8 bits. - - 3.1.1.1. ASCII TYPE - - This is the default type and must be accepted by all FTP - implementations. It is intended primarily for the transfer - of text files, except when both hosts would find the EBCDIC - type more convenient. - - The sender converts the data from an internal character - representation to the standard 8-bit NVT-ASCII - representation (see the Telnet specification). The receiver - will convert the data from the standard form to his own - internal form. - - In accordance with the NVT standard, the sequence - should be used where necessary to denote the end of a line - of text. (See the discussion of file structure at the end - of the Section on Data Representation and Storage.) - - Using the standard NVT-ASCII representation means that data - must be interpreted as 8-bit bytes. - - The Format parameter for ASCII and EBCDIC types is discussed - below. - - - - - - - - -Postel & Reynolds [Page 11] - - - -RFC 959 October 1985 -File Transfer Protocol - - - 3.1.1.2. EBCDIC TYPE - - This type is intended for efficient transfer between hosts - which use EBCDIC for their internal character - representation. - - For transmission, the data are represented as 8-bit EBCDIC - characters. The character code is the only difference - between the functional specifications of EBCDIC and ASCII - types. - - End-of-line (as opposed to end-of-record--see the discussion - of structure) will probably be rarely used with EBCDIC type - for purposes of denoting structure, but where it is - necessary the character should be used. - - 3.1.1.3. IMAGE TYPE - - The data are sent as contiguous bits which, for transfer, - are packed into the 8-bit transfer bytes. The receiving - site must store the data as contiguous bits. The structure - of the storage system might necessitate the padding of the - file (or of each record, for a record-structured file) to - some convenient boundary (byte, word or block). This - padding, which must be all zeros, may occur only at the end - of the file (or at the end of each record) and there must be - a way of identifying the padding bits so that they may be - stripped off if the file is retrieved. The padding - transformation should be well publicized to enable a user to - process a file at the storage site. - - Image type is intended for the efficient storage and - retrieval of files and for the transfer of binary data. It - is recommended that this type be accepted by all FTP - implementations. - - 3.1.1.4. LOCAL TYPE - - The data is transferred in logical bytes of the size - specified by the obligatory second parameter, Byte size. - The value of Byte size must be a decimal integer; there is - no default value. The logical byte size is not necessarily - the same as the transfer byte size. If there is a - difference in byte sizes, then the logical bytes should be - packed contiguously, disregarding transfer byte boundaries - and with any necessary padding at the end. - - - -Postel & Reynolds [Page 12] - - - -RFC 959 October 1985 -File Transfer Protocol - - - When the data reaches the receiving host, it will be - transformed in a manner dependent on the logical byte size - and the particular host. This transformation must be - invertible (i.e., an identical file can be retrieved if the - same parameters are used) and should be well publicized by - the FTP implementors. - - For example, a user sending 36-bit floating-point numbers to - a host with a 32-bit word could send that data as Local byte - with a logical byte size of 36. The receiving host would - then be expected to store the logical bytes so that they - could be easily manipulated; in this example putting the - 36-bit logical bytes into 64-bit double words should - suffice. - - In another example, a pair of hosts with a 36-bit word size - may send data to one another in words by using TYPE L 36. - The data would be sent in the 8-bit transmission bytes - packed so that 9 transmission bytes carried two host words. - - 3.1.1.5. FORMAT CONTROL - - The types ASCII and EBCDIC also take a second (optional) - parameter; this is to indicate what kind of vertical format - control, if any, is associated with a file. The following - data representation types are defined in FTP: - - A character file may be transferred to a host for one of - three purposes: for printing, for storage and later - retrieval, or for processing. If a file is sent for - printing, the receiving host must know how the vertical - format control is represented. In the second case, it must - be possible to store a file at a host and then retrieve it - later in exactly the same form. Finally, it should be - possible to move a file from one host to another and process - the file at the second host without undue trouble. A single - ASCII or EBCDIC format does not satisfy all these - conditions. Therefore, these types have a second parameter - specifying one of the following three formats: - - 3.1.1.5.1. NON PRINT - - This is the default format to be used if the second - (format) parameter is omitted. Non-print format must be - accepted by all FTP implementations. - - - - -Postel & Reynolds [Page 13] - - - -RFC 959 October 1985 -File Transfer Protocol - - - The file need contain no vertical format information. If - it is passed to a printer process, this process may - assume standard values for spacing and margins. - - Normally, this format will be used with files destined - for processing or just storage. - - 3.1.1.5.2. TELNET FORMAT CONTROLS - - The file contains ASCII/EBCDIC vertical format controls - (i.e., , , , , ) which the printer - process will interpret appropriately. , in exactly - this sequence, also denotes end-of-line. - - 3.1.1.5.2. CARRIAGE CONTROL (ASA) - - The file contains ASA (FORTRAN) vertical format control - characters. (See RFC 740 Appendix C; and Communications - of the ACM, Vol. 7, No. 10, p. 606, October 1964.) In a - line or a record formatted according to the ASA Standard, - the first character is not to be printed. Instead, it - should be used to determine the vertical movement of the - paper which should take place before the rest of the - record is printed. - - The ASA Standard specifies the following control - characters: - - Character Vertical Spacing - - blank Move paper up one line - 0 Move paper up two lines - 1 Move paper to top of next page - + No movement, i.e., overprint - - Clearly there must be some way for a printer process to - distinguish the end of the structural entity. If a file - has record structure (see below) this is no problem; - records will be explicitly marked during transfer and - storage. If the file has no record structure, the - end-of-line sequence is used to separate printing lines, - but these format effectors are overridden by the ASA - controls. - - - - - - -Postel & Reynolds [Page 14] - - - -RFC 959 October 1985 -File Transfer Protocol - - - 3.1.2. DATA STRUCTURES - - In addition to different representation types, FTP allows the - structure of a file to be specified. Three file structures are - defined in FTP: - - file-structure, where there is no internal structure and - the file is considered to be a - continuous sequence of data bytes, - - record-structure, where the file is made up of sequential - records, - - and page-structure, where the file is made up of independent - indexed pages. - - File-structure is the default to be assumed if the STRUcture - command has not been used but both file and record structures - must be accepted for "text" files (i.e., files with TYPE ASCII - or EBCDIC) by all FTP implementations. The structure of a file - will affect both the transfer mode of a file (see the Section - on Transmission Modes) and the interpretation and storage of - the file. - - The "natural" structure of a file will depend on which host - stores the file. A source-code file will usually be stored on - an IBM Mainframe in fixed length records but on a DEC TOPS-20 - as a stream of characters partitioned into lines, for example - by . If the transfer of files between such disparate - sites is to be useful, there must be some way for one site to - recognize the other's assumptions about the file. - - With some sites being naturally file-oriented and others - naturally record-oriented there may be problems if a file with - one structure is sent to a host oriented to the other. If a - text file is sent with record-structure to a host which is file - oriented, then that host should apply an internal - transformation to the file based on the record structure. - Obviously, this transformation should be useful, but it must - also be invertible so that an identical file may be retrieved - using record structure. - - In the case of a file being sent with file-structure to a - record-oriented host, there exists the question of what - criteria the host should use to divide the file into records - which can be processed locally. If this division is necessary, - the FTP implementation should use the end-of-line sequence, - - -Postel & Reynolds [Page 15] - - - -RFC 959 October 1985 -File Transfer Protocol - - - for ASCII, or for EBCDIC text files, as the - delimiter. If an FTP implementation adopts this technique, it - must be prepared to reverse the transformation if the file is - retrieved with file-structure. - - 3.1.2.1. FILE STRUCTURE - - File structure is the default to be assumed if the STRUcture - command has not been used. - - In file-structure there is no internal structure and the - file is considered to be a continuous sequence of data - bytes. - - 3.1.2.2. RECORD STRUCTURE - - Record structures must be accepted for "text" files (i.e., - files with TYPE ASCII or EBCDIC) by all FTP implementations. - - In record-structure the file is made up of sequential - records. - - 3.1.2.3. PAGE STRUCTURE - - To transmit files that are discontinuous, FTP defines a page - structure. Files of this type are sometimes known as - "random access files" or even as "holey files". In these - files there is sometimes other information associated with - the file as a whole (e.g., a file descriptor), or with a - section of the file (e.g., page access controls), or both. - In FTP, the sections of the file are called pages. - - To provide for various page sizes and associated - information, each page is sent with a page header. The page - header has the following defined fields: - - Header Length - - The number of logical bytes in the page header - including this byte. The minimum header length is 4. - - Page Index - - The logical page number of this section of the file. - This is not the transmission sequence number of this - page, but the index used to identify this page of the - file. - - -Postel & Reynolds [Page 16] - - - -RFC 959 October 1985 -File Transfer Protocol - - - Data Length - - The number of logical bytes in the page data. The - minimum data length is 0. - - Page Type - - The type of page this is. The following page types - are defined: - - 0 = Last Page - - This is used to indicate the end of a paged - structured transmission. The header length must - be 4, and the data length must be 0. - - 1 = Simple Page - - This is the normal type for simple paged files - with no page level associated control - information. The header length must be 4. - - 2 = Descriptor Page - - This type is used to transmit the descriptive - information for the file as a whole. - - 3 = Access Controlled Page - - This type includes an additional header field - for paged files with page level access control - information. The header length must be 5. - - Optional Fields - - Further header fields may be used to supply per page - control information, for example, per page access - control. - - All fields are one logical byte in length. The logical byte - size is specified by the TYPE command. See Appendix I for - further details and a specific case at the page structure. - - A note of caution about parameters: a file must be stored and - retrieved with the same parameters if the retrieved version is to - - - - -Postel & Reynolds [Page 17] - - - -RFC 959 October 1985 -File Transfer Protocol - - - be identical to the version originally transmitted. Conversely, - FTP implementations must return a file identical to the original - if the parameters used to store and retrieve a file are the same. - - 3.2. ESTABLISHING DATA CONNECTIONS - - The mechanics of transferring data consists of setting up the data - connection to the appropriate ports and choosing the parameters - for transfer. Both the user and the server-DTPs have a default - data port. The user-process default data port is the same as the - control connection port (i.e., U). The server-process default - data port is the port adjacent to the control connection port - (i.e., L-1). - - The transfer byte size is 8-bit bytes. This byte size is relevant - only for the actual transfer of the data; it has no bearing on - representation of the data within a host's file system. - - The passive data transfer process (this may be a user-DTP or a - second server-DTP) shall "listen" on the data port prior to - sending a transfer request command. The FTP request command - determines the direction of the data transfer. The server, upon - receiving the transfer request, will initiate the data connection - to the port. When the connection is established, the data - transfer begins between DTP's, and the server-PI sends a - confirming reply to the user-PI. - - Every FTP implementation must support the use of the default data - ports, and only the USER-PI can initiate a change to non-default - ports. - - It is possible for the user to specify an alternate data port by - use of the PORT command. The user may want a file dumped on a TAC - line printer or retrieved from a third party host. In the latter - case, the user-PI sets up control connections with both - server-PI's. One server is then told (by an FTP command) to - "listen" for a connection which the other will initiate. The - user-PI sends one server-PI a PORT command indicating the data - port of the other. Finally, both are sent the appropriate - transfer commands. The exact sequence of commands and replies - sent between the user-controller and the servers is defined in the - Section on FTP Replies. - - In general, it is the server's responsibility to maintain the data - connection--to initiate it and to close it. The exception to this - - - - -Postel & Reynolds [Page 18] - - - -RFC 959 October 1985 -File Transfer Protocol - - - is when the user-DTP is sending the data in a transfer mode that - requires the connection to be closed to indicate EOF. The server - MUST close the data connection under the following conditions: - - 1. The server has completed sending data in a transfer mode - that requires a close to indicate EOF. - - 2. The server receives an ABORT command from the user. - - 3. The port specification is changed by a command from the - user. - - 4. The control connection is closed legally or otherwise. - - 5. An irrecoverable error condition occurs. - - Otherwise the close is a server option, the exercise of which the - server must indicate to the user-process by either a 250 or 226 - reply only. - - 3.3. DATA CONNECTION MANAGEMENT - - Default Data Connection Ports: All FTP implementations must - support use of the default data connection ports, and only the - User-PI may initiate the use of non-default ports. - - Negotiating Non-Default Data Ports: The User-PI may specify a - non-default user side data port with the PORT command. The - User-PI may request the server side to identify a non-default - server side data port with the PASV command. Since a connection - is defined by the pair of addresses, either of these actions is - enough to get a different data connection, still it is permitted - to do both commands to use new ports on both ends of the data - connection. - - Reuse of the Data Connection: When using the stream mode of data - transfer the end of the file must be indicated by closing the - connection. This causes a problem if multiple files are to be - transfered in the session, due to need for TCP to hold the - connection record for a time out period to guarantee the reliable - communication. Thus the connection can not be reopened at once. - - There are two solutions to this problem. The first is to - negotiate a non-default port. The second is to use another - transfer mode. - - A comment on transfer modes. The stream transfer mode is - - -Postel & Reynolds [Page 19] - - - -RFC 959 October 1985 -File Transfer Protocol - - - inherently unreliable, since one can not determine if the - connection closed prematurely or not. The other transfer modes - (Block, Compressed) do not close the connection to indicate the - end of file. They have enough FTP encoding that the data - connection can be parsed to determine the end of the file. - Thus using these modes one can leave the data connection open - for multiple file transfers. - - 3.4. TRANSMISSION MODES - - The next consideration in transferring data is choosing the - appropriate transmission mode. There are three modes: one which - formats the data and allows for restart procedures; one which also - compresses the data for efficient transfer; and one which passes - the data with little or no processing. In this last case the mode - interacts with the structure attribute to determine the type of - processing. In the compressed mode, the representation type - determines the filler byte. - - All data transfers must be completed with an end-of-file (EOF) - which may be explicitly stated or implied by the closing of the - data connection. For files with record structure, all the - end-of-record markers (EOR) are explicit, including the final one. - For files transmitted in page structure a "last-page" page type is - used. - - NOTE: In the rest of this section, byte means "transfer byte" - except where explicitly stated otherwise. - - For the purpose of standardized transfer, the sending host will - translate its internal end of line or end of record denotation - into the representation prescribed by the transfer mode and file - structure, and the receiving host will perform the inverse - translation to its internal denotation. An IBM Mainframe record - count field may not be recognized at another host, so the - end-of-record information may be transferred as a two byte control - code in Stream mode or as a flagged bit in a Block or Compressed - mode descriptor. End-of-line in an ASCII or EBCDIC file with no - record structure should be indicated by or , - respectively. Since these transformations imply extra work for - some systems, identical systems transferring non-record structured - text files might wish to use a binary representation and stream - mode for the transfer. - - - - - - -Postel & Reynolds [Page 20] - - - -RFC 959 October 1985 -File Transfer Protocol - - - The following transmission modes are defined in FTP: - - 3.4.1. STREAM MODE - - The data is transmitted as a stream of bytes. There is no - restriction on the representation type used; record structures - are allowed. - - In a record structured file EOR and EOF will each be indicated - by a two-byte control code. The first byte of the control code - will be all ones, the escape character. The second byte will - have the low order bit on and zeros elsewhere for EOR and the - second low order bit on for EOF; that is, the byte will have - value 1 for EOR and value 2 for EOF. EOR and EOF may be - indicated together on the last byte transmitted by turning both - low order bits on (i.e., the value 3). If a byte of all ones - was intended to be sent as data, it should be repeated in the - second byte of the control code. - - If the structure is a file structure, the EOF is indicated by - the sending host closing the data connection and all bytes are - data bytes. - - 3.4.2. BLOCK MODE - - The file is transmitted as a series of data blocks preceded by - one or more header bytes. The header bytes contain a count - field, and descriptor code. The count field indicates the - total length of the data block in bytes, thus marking the - beginning of the next data block (there are no filler bits). - The descriptor code defines: last block in the file (EOF) last - block in the record (EOR), restart marker (see the Section on - Error Recovery and Restart) or suspect data (i.e., the data - being transferred is suspected of errors and is not reliable). - This last code is NOT intended for error control within FTP. - It is motivated by the desire of sites exchanging certain types - of data (e.g., seismic or weather data) to send and receive all - the data despite local errors (such as "magnetic tape read - errors"), but to indicate in the transmission that certain - portions are suspect). Record structures are allowed in this - mode, and any representation type may be used. - - The header consists of the three bytes. Of the 24 bits of - header information, the 16 low order bits shall represent byte - count, and the 8 high order bits shall represent descriptor - codes as shown below. - - - -Postel & Reynolds [Page 21] - - - -RFC 959 October 1985 -File Transfer Protocol - - - Block Header - - +----------------+----------------+----------------+ - | Descriptor | Byte Count | - | 8 bits | 16 bits | - +----------------+----------------+----------------+ - - - The descriptor codes are indicated by bit flags in the - descriptor byte. Four codes have been assigned, where each - code number is the decimal value of the corresponding bit in - the byte. - - Code Meaning - - 128 End of data block is EOR - 64 End of data block is EOF - 32 Suspected errors in data block - 16 Data block is a restart marker - - With this encoding, more than one descriptor coded condition - may exist for a particular block. As many bits as necessary - may be flagged. - - The restart marker is embedded in the data stream as an - integral number of 8-bit bytes representing printable - characters in the language being used over the control - connection (e.g., default--NVT-ASCII). (Space, in the - appropriate language) must not be used WITHIN a restart marker. - - For example, to transmit a six-character marker, the following - would be sent: - - +--------+--------+--------+ - |Descrptr| Byte count | - |code= 16| = 6 | - +--------+--------+--------+ - - +--------+--------+--------+ - | Marker | Marker | Marker | - | 8 bits | 8 bits | 8 bits | - +--------+--------+--------+ - - +--------+--------+--------+ - | Marker | Marker | Marker | - | 8 bits | 8 bits | 8 bits | - +--------+--------+--------+ - - -Postel & Reynolds [Page 22] - - - -RFC 959 October 1985 -File Transfer Protocol - - - 3.4.3. COMPRESSED MODE - - There are three kinds of information to be sent: regular data, - sent in a byte string; compressed data, consisting of - replications or filler; and control information, sent in a - two-byte escape sequence. If n>0 bytes (up to 127) of regular - data are sent, these n bytes are preceded by a byte with the - left-most bit set to 0 and the right-most 7 bits containing the - number n. - - Byte string: - - 1 7 8 8 - +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ - |0| n | | d(1) | ... | d(n) | - +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ - ^ ^ - |---n bytes---| - of data - - String of n data bytes d(1),..., d(n) - Count n must be positive. - - To compress a string of n replications of the data byte d, the - following 2 bytes are sent: - - Replicated Byte: - - 2 6 8 - +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ - |1 0| n | | d | - +-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+ - - A string of n filler bytes can be compressed into a single - byte, where the filler byte varies with the representation - type. If the type is ASCII or EBCDIC the filler byte is - (Space, ASCII code 32, EBCDIC code 64). If the type is Image - or Local byte the filler is a zero byte. - - Filler String: - - 2 6 - +-+-+-+-+-+-+-+-+ - |1 1| n | - +-+-+-+-+-+-+-+-+ - - The escape sequence is a double byte, the first of which is the - - -Postel & Reynolds [Page 23] - - - -RFC 959 October 1985 -File Transfer Protocol - - - escape byte (all zeros) and the second of which contains - descriptor codes as defined in Block mode. The descriptor - codes have the same meaning as in Block mode and apply to the - succeeding string of bytes. - - Compressed mode is useful for obtaining increased bandwidth on - very large network transmissions at a little extra CPU cost. - It can be most effectively used to reduce the size of printer - files such as those generated by RJE hosts. - - 3.5. ERROR RECOVERY AND RESTART - - There is no provision for detecting bits lost or scrambled in data - transfer; this level of error control is handled by the TCP. - However, a restart procedure is provided to protect users from - gross system failures (including failures of a host, an - FTP-process, or the underlying network). - - The restart procedure is defined only for the block and compressed - modes of data transfer. It requires the sender of data to insert - a special marker code in the data stream with some marker - information. The marker information has meaning only to the - sender, but must consist of printable characters in the default or - negotiated language of the control connection (ASCII or EBCDIC). - The marker could represent a bit-count, a record-count, or any - other information by which a system may identify a data - checkpoint. The receiver of data, if it implements the restart - procedure, would then mark the corresponding position of this - marker in the receiving system, and return this information to the - user. - - In the event of a system failure, the user can restart the data - transfer by identifying the marker point with the FTP restart - procedure. The following example illustrates the use of the - restart procedure. - - The sender of the data inserts an appropriate marker block in the - data stream at a convenient point. The receiving host marks the - corresponding data point in its file system and conveys the last - known sender and receiver marker information to the user, either - directly or over the control connection in a 110 reply (depending - on who is the sender). In the event of a system failure, the user - or controller process restarts the server at the last server - marker by sending a restart command with server's marker code as - its argument. The restart command is transmitted over the control - - - - -Postel & Reynolds [Page 24] - - - -RFC 959 October 1985 -File Transfer Protocol - - - connection and is immediately followed by the command (such as - RETR, STOR or LIST) which was being executed when the system - failure occurred. - -4. FILE TRANSFER FUNCTIONS - - The communication channel from the user-PI to the server-PI is - established as a TCP connection from the user to the standard server - port. The user protocol interpreter is responsible for sending FTP - commands and interpreting the replies received; the server-PI - interprets commands, sends replies and directs its DTP to set up the - data connection and transfer the data. If the second party to the - data transfer (the passive transfer process) is the user-DTP, then it - is governed through the internal protocol of the user-FTP host; if it - is a second server-DTP, then it is governed by its PI on command from - the user-PI. The FTP replies are discussed in the next section. In - the description of a few of the commands in this section, it is - helpful to be explicit about the possible replies. - - 4.1. FTP COMMANDS - - 4.1.1. ACCESS CONTROL COMMANDS - - The following commands specify access control identifiers - (command codes are shown in parentheses). - - USER NAME (USER) - - The argument field is a Telnet string identifying the user. - The user identification is that which is required by the - server for access to its file system. This command will - normally be the first command transmitted by the user after - the control connections are made (some servers may require - this). Additional identification information in the form of - a password and/or an account command may also be required by - some servers. Servers may allow a new USER command to be - entered at any point in order to change the access control - and/or accounting information. This has the effect of - flushing any user, password, and account information already - supplied and beginning the login sequence again. All - transfer parameters are unchanged and any file transfer in - progress is completed under the old access control - parameters. - - - - - - -Postel & Reynolds [Page 25] - - - -RFC 959 October 1985 -File Transfer Protocol - - - PASSWORD (PASS) - - The argument field is a Telnet string specifying the user's - password. This command must be immediately preceded by the - user name command, and, for some sites, completes the user's - identification for access control. Since password - information is quite sensitive, it is desirable in general - to "mask" it or suppress typeout. It appears that the - server has no foolproof way to achieve this. It is - therefore the responsibility of the user-FTP process to hide - the sensitive password information. - - ACCOUNT (ACCT) - - The argument field is a Telnet string identifying the user's - account. The command is not necessarily related to the USER - command, as some sites may require an account for login and - others only for specific access, such as storing files. In - the latter case the command may arrive at any time. - - There are reply codes to differentiate these cases for the - automation: when account information is required for login, - the response to a successful PASSword command is reply code - 332. On the other hand, if account information is NOT - required for login, the reply to a successful PASSword - command is 230; and if the account information is needed for - a command issued later in the dialogue, the server should - return a 332 or 532 reply depending on whether it stores - (pending receipt of the ACCounT command) or discards the - command, respectively. - - CHANGE WORKING DIRECTORY (CWD) - - This command allows the user to work with a different - directory or dataset for file storage or retrieval without - altering his login or accounting information. Transfer - parameters are similarly unchanged. The argument is a - pathname specifying a directory or other system dependent - file group designator. - - CHANGE TO PARENT DIRECTORY (CDUP) - - This command is a special case of CWD, and is included to - simplify the implementation of programs for transferring - directory trees between operating systems having different - - - - -Postel & Reynolds [Page 26] - - - -RFC 959 October 1985 -File Transfer Protocol - - - syntaxes for naming the parent directory. The reply codes - shall be identical to the reply codes of CWD. See - Appendix II for further details. - - STRUCTURE MOUNT (SMNT) - - This command allows the user to mount a different file - system data structure without altering his login or - accounting information. Transfer parameters are similarly - unchanged. The argument is a pathname specifying a - directory or other system dependent file group designator. - - REINITIALIZE (REIN) - - This command terminates a USER, flushing all I/O and account - information, except to allow any transfer in progress to be - completed. All parameters are reset to the default settings - and the control connection is left open. This is identical - to the state in which a user finds himself immediately after - the control connection is opened. A USER command may be - expected to follow. - - LOGOUT (QUIT) - - This command terminates a USER and if file transfer is not - in progress, the server closes the control connection. If - file transfer is in progress, the connection will remain - open for result response and the server will then close it. - If the user-process is transferring files for several USERs - but does not wish to close and then reopen connections for - each, then the REIN command should be used instead of QUIT. - - An unexpected close on the control connection will cause the - server to take the effective action of an abort (ABOR) and a - logout (QUIT). - - 4.1.2. TRANSFER PARAMETER COMMANDS - - All data transfer parameters have default values, and the - commands specifying data transfer parameters are required only - if the default parameter values are to be changed. The default - value is the last specified value, or if no value has been - specified, the standard default value is as stated here. This - implies that the server must "remember" the applicable default - values. The commands may be in any order except that they must - precede the FTP service request. The following commands - specify data transfer parameters: - - -Postel & Reynolds [Page 27] - - - -RFC 959 October 1985 -File Transfer Protocol - - - DATA PORT (PORT) - - The argument is a HOST-PORT specification for the data port - to be used in data connection. There are defaults for both - the user and server data ports, and under normal - circumstances this command and its reply are not needed. If - this command is used, the argument is the concatenation of a - 32-bit internet host address and a 16-bit TCP port address. - This address information is broken into 8-bit fields and the - value of each field is transmitted as a decimal number (in - character string representation). The fields are separated - by commas. A port command would be: - - PORT h1,h2,h3,h4,p1,p2 - - where h1 is the high order 8 bits of the internet host - address. - - PASSIVE (PASV) - - This command requests the server-DTP to "listen" on a data - port (which is not its default data port) and to wait for a - connection rather than initiate one upon receipt of a - transfer command. The response to this command includes the - host and port address this server is listening on. - - REPRESENTATION TYPE (TYPE) - - The argument specifies the representation type as described - in the Section on Data Representation and Storage. Several - types take a second parameter. The first parameter is - denoted by a single Telnet character, as is the second - Format parameter for ASCII and EBCDIC; the second parameter - for local byte is a decimal integer to indicate Bytesize. - The parameters are separated by a (Space, ASCII code - 32). - - The following codes are assigned for type: - - \ / - A - ASCII | | N - Non-print - |-><-| T - Telnet format effectors - E - EBCDIC| | C - Carriage Control (ASA) - / \ - I - Image - - L - Local byte Byte size - - -Postel & Reynolds [Page 28] - - - -RFC 959 October 1985 -File Transfer Protocol - - - The default representation type is ASCII Non-print. If the - Format parameter is changed, and later just the first - argument is changed, Format then returns to the Non-print - default. - - FILE STRUCTURE (STRU) - - The argument is a single Telnet character code specifying - file structure described in the Section on Data - Representation and Storage. - - The following codes are assigned for structure: - - F - File (no record structure) - R - Record structure - P - Page structure - - The default structure is File. - - TRANSFER MODE (MODE) - - The argument is a single Telnet character code specifying - the data transfer modes described in the Section on - Transmission Modes. - - The following codes are assigned for transfer modes: - - S - Stream - B - Block - C - Compressed - - The default transfer mode is Stream. - - 4.1.3. FTP SERVICE COMMANDS - - The FTP service commands define the file transfer or the file - system function requested by the user. The argument of an FTP - service command will normally be a pathname. The syntax of - pathnames must conform to server site conventions (with - standard defaults applicable), and the language conventions of - the control connection. The suggested default handling is to - use the last specified device, directory or file name, or the - standard default defined for local users. The commands may be - in any order except that a "rename from" command must be - followed by a "rename to" command and the restart command must - be followed by the interrupted service command (e.g., STOR or - RETR). The data, when transferred in response to FTP service - - -Postel & Reynolds [Page 29] - - - -RFC 959 October 1985 -File Transfer Protocol - - - commands, shall always be sent over the data connection, except - for certain informative replies. The following commands - specify FTP service requests: - - RETRIEVE (RETR) - - This command causes the server-DTP to transfer a copy of the - file, specified in the pathname, to the server- or user-DTP - at the other end of the data connection. The status and - contents of the file at the server site shall be unaffected. - - STORE (STOR) - - This command causes the server-DTP to accept the data - transferred via the data connection and to store the data as - a file at the server site. If the file specified in the - pathname exists at the server site, then its contents shall - be replaced by the data being transferred. A new file is - created at the server site if the file specified in the - pathname does not already exist. - - STORE UNIQUE (STOU) - - This command behaves like STOR except that the resultant - file is to be created in the current directory under a name - unique to that directory. The 250 Transfer Started response - must include the name generated. - - APPEND (with create) (APPE) - - This command causes the server-DTP to accept the data - transferred via the data connection and to store the data in - a file at the server site. If the file specified in the - pathname exists at the server site, then the data shall be - appended to that file; otherwise the file specified in the - pathname shall be created at the server site. - - ALLOCATE (ALLO) - - This command may be required by some servers to reserve - sufficient storage to accommodate the new file to be - transferred. The argument shall be a decimal integer - representing the number of bytes (using the logical byte - size) of storage to be reserved for the file. For files - sent with record or page structure a maximum record or page - size (in logical bytes) might also be necessary; this is - indicated by a decimal integer in a second argument field of - - -Postel & Reynolds [Page 30] - - - -RFC 959 October 1985 -File Transfer Protocol - - - the command. This second argument is optional, but when - present should be separated from the first by the three - Telnet characters R . This command shall be - followed by a STORe or APPEnd command. The ALLO command - should be treated as a NOOP (no operation) by those servers - which do not require that the maximum size of the file be - declared beforehand, and those servers interested in only - the maximum record or page size should accept a dummy value - in the first argument and ignore it. - - RESTART (REST) - - The argument field represents the server marker at which - file transfer is to be restarted. This command does not - cause file transfer but skips over the file to the specified - data checkpoint. This command shall be immediately followed - by the appropriate FTP service command which shall cause - file transfer to resume. - - RENAME FROM (RNFR) - - This command specifies the old pathname of the file which is - to be renamed. This command must be immediately followed by - a "rename to" command specifying the new file pathname. - - RENAME TO (RNTO) - - This command specifies the new pathname of the file - specified in the immediately preceding "rename from" - command. Together the two commands cause a file to be - renamed. - - ABORT (ABOR) - - This command tells the server to abort the previous FTP - service command and any associated transfer of data. The - abort command may require "special action", as discussed in - the Section on FTP Commands, to force recognition by the - server. No action is to be taken if the previous command - has been completed (including data transfer). The control - connection is not to be closed by the server, but the data - connection must be closed. - - There are two cases for the server upon receipt of this - command: (1) the FTP service command was already completed, - or (2) the FTP service command is still in progress. - - - -Postel & Reynolds [Page 31] - - - -RFC 959 October 1985 -File Transfer Protocol - - - In the first case, the server closes the data connection - (if it is open) and responds with a 226 reply, indicating - that the abort command was successfully processed. - - In the second case, the server aborts the FTP service in - progress and closes the data connection, returning a 426 - reply to indicate that the service request terminated - abnormally. The server then sends a 226 reply, - indicating that the abort command was successfully - processed. - - DELETE (DELE) - - This command causes the file specified in the pathname to be - deleted at the server site. If an extra level of protection - is desired (such as the query, "Do you really wish to - delete?"), it should be provided by the user-FTP process. - - REMOVE DIRECTORY (RMD) - - This command causes the directory specified in the pathname - to be removed as a directory (if the pathname is absolute) - or as a subdirectory of the current working directory (if - the pathname is relative). See Appendix II. - - MAKE DIRECTORY (MKD) - - This command causes the directory specified in the pathname - to be created as a directory (if the pathname is absolute) - or as a subdirectory of the current working directory (if - the pathname is relative). See Appendix II. - - PRINT WORKING DIRECTORY (PWD) - - This command causes the name of the current working - directory to be returned in the reply. See Appendix II. - - LIST (LIST) - - This command causes a list to be sent from the server to the - passive DTP. If the pathname specifies a directory or other - group of files, the server should transfer a list of files - in the specified directory. If the pathname specifies a - file then the server should send current information on the - file. A null argument implies the user's current working or - default directory. The data transfer is over the data - connection in type ASCII or type EBCDIC. (The user must - - -Postel & Reynolds [Page 32] - - - -RFC 959 October 1985 -File Transfer Protocol - - - ensure that the TYPE is appropriately ASCII or EBCDIC). - Since the information on a file may vary widely from system - to system, this information may be hard to use automatically - in a program, but may be quite useful to a human user. - - NAME LIST (NLST) - - This command causes a directory listing to be sent from - server to user site. The pathname should specify a - directory or other system-specific file group descriptor; a - null argument implies the current directory. The server - will return a stream of names of files and no other - information. The data will be transferred in ASCII or - EBCDIC type over the data connection as valid pathname - strings separated by or . (Again the user must - ensure that the TYPE is correct.) This command is intended - to return information that can be used by a program to - further process the files automatically. For example, in - the implementation of a "multiple get" function. - - SITE PARAMETERS (SITE) - - This command is used by the server to provide services - specific to his system that are essential to file transfer - but not sufficiently universal to be included as commands in - the protocol. The nature of these services and the - specification of their syntax can be stated in a reply to - the HELP SITE command. - - SYSTEM (SYST) - - This command is used to find out the type of operating - system at the server. The reply shall have as its first - word one of the system names listed in the current version - of the Assigned Numbers document [4]. - - STATUS (STAT) - - This command shall cause a status response to be sent over - the control connection in the form of a reply. The command - may be sent during a file transfer (along with the Telnet IP - and Synch signals--see the Section on FTP Commands) in which - case the server will respond with the status of the - operation in progress, or it may be sent between file - transfers. In the latter case, the command may have an - argument field. If the argument is a pathname, the command - is analogous to the "list" command except that data shall be - - -Postel & Reynolds [Page 33] - - - -RFC 959 October 1985 -File Transfer Protocol - - - transferred over the control connection. If a partial - pathname is given, the server may respond with a list of - file names or attributes associated with that specification. - If no argument is given, the server should return general - status information about the server FTP process. This - should include current values of all transfer parameters and - the status of connections. - - HELP (HELP) - - This command shall cause the server to send helpful - information regarding its implementation status over the - control connection to the user. The command may take an - argument (e.g., any command name) and return more specific - information as a response. The reply is type 211 or 214. - It is suggested that HELP be allowed before entering a USER - command. The server may use this reply to specify - site-dependent parameters, e.g., in response to HELP SITE. - - NOOP (NOOP) - - This command does not affect any parameters or previously - entered commands. It specifies no action other than that the - server send an OK reply. - - The File Transfer Protocol follows the specifications of the Telnet - protocol for all communications over the control connection. Since - the language used for Telnet communication may be a negotiated - option, all references in the next two sections will be to the - "Telnet language" and the corresponding "Telnet end-of-line code". - Currently, one may take these to mean NVT-ASCII and . No other - specifications of the Telnet protocol will be cited. - - FTP commands are "Telnet strings" terminated by the "Telnet end of - line code". The command codes themselves are alphabetic characters - terminated by the character (Space) if parameters follow and - Telnet-EOL otherwise. The command codes and the semantics of - commands are described in this section; the detailed syntax of - commands is specified in the Section on Commands, the reply sequences - are discussed in the Section on Sequencing of Commands and Replies, - and scenarios illustrating the use of commands are provided in the - Section on Typical FTP Scenarios. - - FTP commands may be partitioned as those specifying access-control - identifiers, data transfer parameters, or FTP service requests. - Certain commands (such as ABOR, STAT, QUIT) may be sent over the - control connection while a data transfer is in progress. Some - - -Postel & Reynolds [Page 34] - - - -RFC 959 October 1985 -File Transfer Protocol - - - servers may not be able to monitor the control and data connections - simultaneously, in which case some special action will be necessary - to get the server's attention. The following ordered format is - tentatively recommended: - - 1. User system inserts the Telnet "Interrupt Process" (IP) signal - in the Telnet stream. - - 2. User system sends the Telnet "Synch" signal. - - 3. User system inserts the command (e.g., ABOR) in the Telnet - stream. - - 4. Server PI, after receiving "IP", scans the Telnet stream for - EXACTLY ONE FTP command. - - (For other servers this may not be necessary but the actions listed - above should have no unusual effect.) - - 4.2. FTP REPLIES - - Replies to File Transfer Protocol commands are devised to ensure - the synchronization of requests and actions in the process of file - transfer, and to guarantee that the user process always knows the - state of the Server. Every command must generate at least one - reply, although there may be more than one; in the latter case, - the multiple replies must be easily distinguished. In addition, - some commands occur in sequential groups, such as USER, PASS and - ACCT, or RNFR and RNTO. The replies show the existence of an - intermediate state if all preceding commands have been successful. - A failure at any point in the sequence necessitates the repetition - of the entire sequence from the beginning. - - The details of the command-reply sequence are made explicit in - a set of state diagrams below. - - An FTP reply consists of a three digit number (transmitted as - three alphanumeric characters) followed by some text. The number - is intended for use by automata to determine what state to enter - next; the text is intended for the human user. It is intended - that the three digits contain enough encoded information that the - user-process (the User-PI) will not need to examine the text and - may either discard it or pass it on to the user, as appropriate. - In particular, the text may be server-dependent, so there are - likely to be varying texts for each reply code. - - A reply is defined to contain the 3-digit code, followed by Space - - -Postel & Reynolds [Page 35] - - - -RFC 959 October 1985 -File Transfer Protocol - - - , followed by one line of text (where some maximum line length - has been specified), and terminated by the Telnet end-of-line - code. There will be cases however, where the text is longer than - a single line. In these cases the complete text must be bracketed - so the User-process knows when it may stop reading the reply (i.e. - stop processing input on the control connection) and go do other - things. This requires a special format on the first line to - indicate that more than one line is coming, and another on the - last line to designate it as the last. At least one of these must - contain the appropriate reply code to indicate the state of the - transaction. To satisfy all factions, it was decided that both - the first and last line codes should be the same. - - Thus the format for multi-line replies is that the first line - will begin with the exact required reply code, followed - immediately by a Hyphen, "-" (also known as Minus), followed by - text. The last line will begin with the same code, followed - immediately by Space , optionally some text, and the Telnet - end-of-line code. - - For example: - 123-First line - Second line - 234 A line beginning with numbers - 123 The last line - - The user-process then simply needs to search for the second - occurrence of the same reply code, followed by (Space), at - the beginning of a line, and ignore all intermediary lines. If - an intermediary line begins with a 3-digit number, the Server - must pad the front to avoid confusion. - - This scheme allows standard system routines to be used for - reply information (such as for the STAT reply), with - "artificial" first and last lines tacked on. In rare cases - where these routines are able to generate three digits and a - Space at the beginning of any line, the beginning of each - text line should be offset by some neutral text, like Space. - - This scheme assumes that multi-line replies may not be nested. - - The three digits of the reply each have a special significance. - This is intended to allow a range of very simple to very - sophisticated responses by the user-process. The first digit - denotes whether the response is good, bad or incomplete. - (Referring to the state diagram), an unsophisticated user-process - will be able to determine its next action (proceed as planned, - - -Postel & Reynolds [Page 36] - - - -RFC 959 October 1985 -File Transfer Protocol - - - redo, retrench, etc.) by simply examining this first digit. A - user-process that wants to know approximately what kind of error - occurred (e.g. file system error, command syntax error) may - examine the second digit, reserving the third digit for the finest - gradation of information (e.g., RNTO command without a preceding - RNFR). - - There are five values for the first digit of the reply code: - - 1yz Positive Preliminary reply - - The requested action is being initiated; expect another - reply before proceeding with a new command. (The - user-process sending another command before the - completion reply would be in violation of protocol; but - server-FTP processes should queue any commands that - arrive while a preceding command is in progress.) This - type of reply can be used to indicate that the command - was accepted and the user-process may now pay attention - to the data connections, for implementations where - simultaneous monitoring is difficult. The server-FTP - process may send at most, one 1yz reply per command. - - 2yz Positive Completion reply - - The requested action has been successfully completed. A - new request may be initiated. - - 3yz Positive Intermediate reply - - The command has been accepted, but the requested action - is being held in abeyance, pending receipt of further - information. The user should send another command - specifying this information. This reply is used in - command sequence groups. - - 4yz Transient Negative Completion reply - - The command was not accepted and the requested action did - not take place, but the error condition is temporary and - the action may be requested again. The user should - return to the beginning of the command sequence, if any. - It is difficult to assign a meaning to "transient", - particularly when two distinct sites (Server- and - User-processes) have to agree on the interpretation. - Each reply in the 4yz category might have a slightly - different time value, but the intent is that the - - -Postel & Reynolds [Page 37] - - - -RFC 959 October 1985 -File Transfer Protocol - - - user-process is encouraged to try again. A rule of thumb - in determining if a reply fits into the 4yz or the 5yz - (Permanent Negative) category is that replies are 4yz if - the commands can be repeated without any change in - command form or in properties of the User or Server - (e.g., the command is spelled the same with the same - arguments used; the user does not change his file access - or user name; the server does not put up a new - implementation.) - - 5yz Permanent Negative Completion reply - - The command was not accepted and the requested action did - not take place. The User-process is discouraged from - repeating the exact request (in the same sequence). Even - some "permanent" error conditions can be corrected, so - the human user may want to direct his User-process to - reinitiate the command sequence by direct action at some - point in the future (e.g., after the spelling has been - changed, or the user has altered his directory status.) - - The following function groupings are encoded in the second - digit: - - x0z Syntax - These replies refer to syntax errors, - syntactically correct commands that don't fit any - functional category, unimplemented or superfluous - commands. - - x1z Information - These are replies to requests for - information, such as status or help. - - x2z Connections - Replies referring to the control and - data connections. - - x3z Authentication and accounting - Replies for the login - process and accounting procedures. - - x4z Unspecified as yet. - - x5z File system - These replies indicate the status of the - Server file system vis-a-vis the requested transfer or - other file system action. - - The third digit gives a finer gradation of meaning in each of - the function categories, specified by the second digit. The - list of replies below will illustrate this. Note that the text - - -Postel & Reynolds [Page 38] - - - -RFC 959 October 1985 -File Transfer Protocol - - - associated with each reply is recommended, rather than - mandatory, and may even change according to the command with - which it is associated. The reply codes, on the other hand, - must strictly follow the specifications in the last section; - that is, Server implementations should not invent new codes for - situations that are only slightly different from the ones - described here, but rather should adapt codes already defined. - - A command such as TYPE or ALLO whose successful execution - does not offer the user-process any new information will - cause a 200 reply to be returned. If the command is not - implemented by a particular Server-FTP process because it - has no relevance to that computer system, for example ALLO - at a TOPS20 site, a Positive Completion reply is still - desired so that the simple User-process knows it can proceed - with its course of action. A 202 reply is used in this case - with, for example, the reply text: "No storage allocation - necessary." If, on the other hand, the command requests a - non-site-specific action and is unimplemented, the response - is 502.

DECLARATIVE SPECIFICATIONS - - 5.1. MINIMUM IMPLEMENTATION - - In order to make FTP workable without needless error messages, the - following minimum implementation is required for all servers: - - TYPE - ASCII Non-print - MODE - Stream - STRUCTURE - File, Record - COMMANDS - USER, QUIT, PORT, - TYPE, MODE, STRU, - for the default values - RETR, STOR, - NOOP. - - The default values for transfer parameters are: - - TYPE - ASCII Non-print - MODE - Stream - STRU - File - - All hosts must accept the above as the standard defaults. - - - - - - - - -Postel & Reynolds [Page 43] - - - -RFC 959 October 1985 -File Transfer Protocol - - - 5.2. CONNECTIONS - - The server protocol interpreter shall "listen" on Port L. The - user or user protocol interpreter shall initiate the full-duplex - control connection. Server- and user- processes should follow the - conventions of the Telnet protocol as specified in the - ARPA-Internet Protocol Handbook [1]. Servers are under no - obligation to provide for editing of command lines and may require - that it be done in the user host. The control connection shall be - closed by the server at the user's request after all transfers and - replies are completed. - - The user-DTP must "listen" on the specified data port; this may be - the default user port (U) or a port specified in the PORT command. - The server shall initiate the data connection from his own default - data port (L-1) using the specified user data port. The direction - of the transfer and the port used will be determined by the FTP - service command. - - Note that all FTP implementation must support data transfer using - the default port, and that only the USER-PI may initiate the use - of non-default ports. - - When data is to be transferred between two servers, A and B (refer - to Figure 2), the user-PI, C, sets up control connections with - both server-PI's. One of the servers, say A, is then sent a PASV - command telling him to "listen" on his data port rather than - initiate a connection when he receives a transfer service command. - When the user-PI receives an acknowledgment to the PASV command, - which includes the identity of the host and port being listened - on, the user-PI then sends A's port, a, to B in a PORT command; a - reply is returned. The user-PI may then send the corresponding - service commands to A and B. Server B initiates the connection - and the transfer proceeds. The command-reply sequence is listed - below where the messages are vertically synchronous but - horizontally asynchronous: - - - - - - - - - - - - - -Postel & Reynolds [Page 44] - - - -RFC 959 October 1985 -File Transfer Protocol - - - User-PI - Server A User-PI - Server B - ------------------ ------------------ - - C->A : Connect C->B : Connect - C->A : PASV - A->C : 227 Entering Passive Mode.

If the data connection is to be closed following a - data transfer where closing the connection is not required to - indicate the end-of-file, the server must do so immediately. - Waiting until after a new transfer command is not permitted - because the user-process will have already tested the data - connection to see if it needs to do a "listen"; (remember that the - user must "listen" on a closed data port BEFORE sending the - transfer request). To prevent a race condition here, the server - sends a reply (226) after closing the data connection (or if the - connection is left open, a "file transfer completed" reply (250) - and the user-PI should wait for one of these replies before - issuing a new transfer command). - - Any time either the user or server see that the connection is - being closed by the other side, it should promptly read any - remaining data queued on the connection and issue the close on its - own side. - - 5.3. COMMANDS - - The commands are Telnet character strings transmitted over the - control connections as described in the Section on FTP Commands. - The command functions and semantics are described in the Section - on Access Control Commands, Transfer Parameter Commands, FTP - Service Commands, and Miscellaneous Commands. The command syntax - is specified here. - - The commands begin with a command code followed by an argument - field. The command codes are four or fewer alphabetic characters. - Upper and lower case alphabetic characters are to be treated - identically. Thus, any of the following may represent the - retrieve command: - - -Postel & Reynolds [Page 45] - - - -RFC 959 October 1985 -File Transfer Protocol - - - RETR Retr retr ReTr rETr - - This also applies to any symbols representing parameter values, - such as A or a for ASCII TYPE. The command codes and the argument - fields are separated by one or more spaces. - - The argument field consists of a variable length character string - ending with the character sequence (Carriage Return, Line - Feed) for NVT-ASCII representation; for other negotiated languages - a different end of line character might be used. It should be - noted that the server is to take no action until the end of line - code is received. - - The syntax is specified below in NVT-ASCII. All characters in the - argument field are ASCII characters including any ASCII - represented decimal integers. Square brackets denote an optional - argument field.

SEQUENCING OF COMMANDS AND REPLIES - - The communication between the user and server is intended to be an - alternating dialogue. As such, the user issues an FTP command and - the server responds with a prompt primary reply. The user should - wait for this initial primary success or failure response before - sending further commands. - - Certain commands require a second reply for which the user should - also wait. These replies may, for example, report on the progress - or completion of file transfer or the closing of the data - connection. They are secondary replies to file transfer commands. - - One important group of informational replies is the connection - greetings. Under normal circumstances, a server will send a 220 - reply, "awaiting input", when the connection is completed. The - user should wait for this greeting message before sending any - commands. If the server is unable to accept input right away, a - 120 "expected delay" reply should be sent immediately and a 220 - reply when ready. The user will then know not to hang up if there - is a delay. - - Spontaneous Replies - - Sometimes "the system" spontaneously has a message to be sent - to a user (usually all users). For example, "System going down - in 15 minutes". There is no provision in FTP for such - spontaneous information to be sent from the server to the user. - It is recommended that such information be queued in the - server-PI and delivered to the user-PI in the next reply - (possibly making it a multi-line reply). - - The table below lists alternative success and failure replies for - each command. These must be strictly adhered to; a server may - substitute text in the replies, but the meaning and action implied - by the code numbers and by the specific command reply sequence - cannot be altered. - - Command-Reply Sequences - - In this section, the command-reply sequence is presented. Each - command is listed with its possible replies; command groups are - listed together. Preliminary replies are listed first (with - their succeeding replies indented and under them), then - positive and negative completion, and finally intermediary - - - - -Postel & Reynolds [Page 49] - - - -RFC 959 October 1985 -File Transfer Protocol - - - replies with the remaining commands from the sequence - following.

STATE DIAGRAMS - - Here we present state diagrams for a very simple minded FTP - implementation. Only the first digit of the reply codes is used. - There is one state diagram for each group of FTP commands or command - sequences. - - The command groupings were determined by constructing a model for - each command then collecting together the commands with structurally - identical models. - - For each command or command sequence there are three possible - outcomes: success (S), failure (F), and error (E).

CONNECTION ESTABLISHMENT - - The FTP control connection is established via TCP between the user - process port U and the server process port L. This protocol is - assigned the service port 21 (25 octal), that is L=21. - - - -Postel & Reynolds [Page 59] - - - -RFC 959 October 1985 -File Transfer Protocol - - -APPENDIX I - PAGE STRUCTURE - - The need for FTP to support page structure derives principally from - the need to support efficient transmission of files between TOPS-20 - systems, particularly the files used by NLS. - - The file system of TOPS-20 is based on the concept of pages. The - operating system is most efficient at manipulating files as pages. - The operating system provides an interface to the file system so that - many applications view files as sequential streams of characters. - However, a few applications use the underlying page structures - directly, and some of these create holey files. - - A TOPS-20 disk file consists of four things: a pathname, a page - table, a (possibly empty) set of pages, and a set of attributes. - - The pathname is specified in the RETR or STOR command. It includes - the directory name, file name, file name extension, and generation - number. - - The page table contains up to 2**18 entries. Each entry may be - EMPTY, or may point to a page. If it is not empty, there are also - some page-specific access bits; not all pages of a file need have the - same access protection. - - A page is a contiguous set of 512 words of 36 bits each. - - The attributes of the file, in the File Descriptor Block (FDB), - contain such things as creation time, write time, read time, writer's - byte-size, end-of-file pointer, count of reads and writes, backup - system tape numbers, etc. - - Note that there is NO requirement that entries in the page table be - contiguous. There may be empty page table slots between occupied - ones. Also, the end of file pointer is simply a number. There is no - requirement that it in fact point at the "last" datum in the file. - Ordinary sequential I/O calls in TOPS-20 will cause the end of file - pointer to be left after the last datum written, but other operations - may cause it not to be so, if a particular programming system so - requires. - - In fact, in both of these special cases, "holey" files and - end-of-file pointers NOT at the end of the file, occur with NLS data - files. - - - - - -Postel & Reynolds [Page 60] - - - -RFC 959 October 1985 -File Transfer Protocol - - - The TOPS-20 paged files can be sent with the FTP transfer parameters: - TYPE L 36, STRU P, and MODE S (in fact, any mode could be used). - - Each page of information has a header. Each header field, which is a - logical byte, is a TOPS-20 word, since the TYPE is L 36. - - The header fields are: - - Word 0: Header Length. - - The header length is 5. - - Word 1: Page Index. - - If the data is a disk file page, this is the number of that - page in the file's page map. Empty pages (holes) in the file - are simply not sent. Note that a hole is NOT the same as a - page of zeros. - - Word 2: Data Length. - - The number of data words in this page, following the header. - Thus, the total length of the transmission unit is the Header - Length plus the Data Length. - - Word 3: Page Type. - - A code for what type of chunk this is. A data page is type 3, - the FDB page is type 2. - - Word 4: Page Access Control. - - The access bits associated with the page in the file's page - map. (This full word quantity is put into AC2 of an SPACS by - the program reading from net to disk.) - - After the header are Data Length data words. Data Length is - currently either 512 for a data page or 31 for an FDB. Trailing - zeros in a disk file page may be discarded, making Data Length less - than 512 in that case. - - - - - - - - - -Postel & Reynolds [Page 61] - - - -RFC 959 October 1985 -File Transfer Protocol - - -APPENDIX II - DIRECTORY COMMANDS - - Since UNIX has a tree-like directory structure in which directories - are as easy to manipulate as ordinary files, it is useful to expand - the FTP servers on these machines to include commands which deal with - the creation of directories. Since there are other hosts on the - ARPA-Internet which have tree-like directories (including TOPS-20 and - Multics), these commands are as general as possible. - - Four directory commands have been added to FTP: - - MKD pathname - - Make a directory with the name "pathname". - - RMD pathname - - Remove the directory with the name "pathname". - - PWD - - Print the current working directory name. - - CDUP - - Change to the parent of the current working directory. - - The "pathname" argument should be created (removed) as a - subdirectory of the current working directory, unless the "pathname" - string contains sufficient information to specify otherwise to the - server, e.g., "pathname" is an absolute pathname (in UNIX and - Multics), or pathname is something like "" to - TOPS-20. - - REPLY CODES - - The CDUP command is a special case of CWD, and is included to - simplify the implementation of programs for transferring directory - trees between operating systems having different syntaxes for - naming the parent directory. The reply codes for CDUP be - identical to the reply codes of CWD. - - The reply codes for RMD be identical to the reply codes for its - file analogue, DELE. - - The reply codes for MKD, however, are a bit more complicated. A - freshly created directory will probably be the object of a future - - -Postel & Reynolds [Page 62] - - - -RFC 959 October 1985 -File Transfer Protocol - - - CWD command. Unfortunately, the argument to MKD may not always be - a suitable argument for CWD. This is the case, for example, when - a TOPS-20 subdirectory is created by giving just the subdirectory - name. That is, with a TOPS-20 server FTP, the command sequence - - MKD MYDIR - CWD MYDIR - - will fail. The new directory may only be referred to by its - "absolute" name; e.g., if the MKD command above were issued while - connected to the directory , the new subdirectory - could only be referred to by the name . - - Even on UNIX and Multics, however, the argument given to MKD may - not be suitable. If it is a "relative" pathname (i.e., a pathname - which is interpreted relative to the current directory), the user - would need to be in the same current directory in order to reach - the subdirectory. Depending on the application, this may be - inconvenient. It is not very robust in any case. - - To solve these problems, upon successful completion of an MKD - command, the server should return a line of the form: - - 257"" - - That is, the server will tell the user what string to use when - referring to the created directory. The directory name can - contain any character; embedded double-quotes should be escaped by - double-quotes (the "quote-doubling" convention). - - For example, a user connects to the directory /usr/dm, and creates - a subdirectory, named pathname: - - CWD /usr/dm - 200 directory changed to /usr/dm - MKD pathname - 257 "/usr/dm/pathname" directory created - - An example with an embedded double quote: - - MKD foo"bar - 257 "/usr/dm/foo""bar" directory created - CWD /usr/dm/foo"bar - 200 directory changed to /usr/dm/foo"bar - - - - - -Postel & Reynolds [Page 63] - - - -RFC 959 October 1985 -File Transfer Protocol - - - The prior existence of a subdirectory with the same name is an - error, and the server must return an "access denied" error reply - in that case. - - CWD /usr/dm - 200 directory changed to /usr/dm - MKD pathname - 521-"/usr/dm/pathname" directory already exists; - 521 taking no action. - - The failure replies for MKD are analogous to its file creating - cousin, STOR. Also, an "access denied" return is given if a file - name with the same name as the subdirectory will conflict with the - creation of the subdirectory (this is a problem on UNIX, but - shouldn't be one on TOPS-20). - - Essentially because the PWD command returns the same type of - information as the successful MKD command, the successful PWD - command uses the 257 reply code as well. - - SUBTLETIES - - Because these commands will be most useful in transferring - subtrees from one machine to another, carefully observe that the - argument to MKD is to be interpreted as a sub-directory of the - current working directory, unless it contains enough information - for the destination host to tell otherwise. A hypothetical - example of its use in the TOPS-20 world: - - CWD - 200 Working directory changed - MKD overrainbow - 257 "" directory created - CWD overrainbow - 431 No such directory - CWD - 200 Working directory changed - - CWD - 200 Working directory changed to - MKD - 257 "" directory created - CWD - - Note that the first example results in a subdirectory of the - connected directory. In contrast, the argument in the second - example contains enough information for TOPS-20 to tell that the - - -Postel & Reynolds [Page 64] - - - -RFC 959 October 1985 -File Transfer Protocol - - - directory is a top-level directory. Note also that - in the first example the user "violated" the protocol by - attempting to access the freshly created directory with a name - other than the one returned by TOPS-20. Problems could have - resulted in this case had there been an directory; - this is an ambiguity inherent in some TOPS-20 implementations. - Similar considerations apply to the RMD command. The point is - this: except where to do so would violate a host's conventions for - denoting relative versus absolute pathnames, the host should treat - the operands of the MKD and RMD commands as subdirectories. The - 257 reply to the MKD command must always contain the absolute - pathname of the created directory. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Postel & Reynolds [Page 65] - - - -RFC 959 October 1985 -File Transfer Protocol - - -APPENDIX III - RFCs on FTP - - Bhushan, Abhay, "A File Transfer Protocol", RFC 114 (NIC 5823), - MIT-Project MAC, 16 April 1971. - - Harslem, Eric, and John Heafner, "Comments on RFC 114 (A File - Transfer Protocol)", RFC 141 (NIC 6726), RAND, 29 April 1971. - - Bhushan, Abhay, et al, "The File Transfer Protocol", RFC 172 - (NIC 6794), MIT-Project MAC, 23 June 1971. - - Braden, Bob, "Comments on DTP and FTP Proposals", RFC 238 (NIC 7663), - UCLA/CCN, 29 September 1971. - - Bhushan, Abhay, et al, "The File Transfer Protocol", RFC 265 - (NIC 7813), MIT-Project MAC, 17 November 1971. - - McKenzie, Alex, "A Suggested Addition to File Transfer Protocol", - RFC 281 (NIC 8163), BBN, 8 December 1971. - - Bhushan, Abhay, "The Use of "Set Data Type" Transaction in File - Transfer Protocol", RFC 294 (NIC 8304), MIT-Project MAC, - 25 January 1972. - - Bhushan, Abhay, "The File Transfer Protocol", RFC 354 (NIC 10596), - MIT-Project MAC, 8 July 1972. - - Bhushan, Abhay, "Comments on the File Transfer Protocol (RFC 354)", - RFC 385 (NIC 11357), MIT-Project MAC, 18 August 1972. - - Hicks, Greg, "User FTP Documentation", RFC 412 (NIC 12404), Utah, - 27 November 1972. - - Bhushan, Abhay, "File Transfer Protocol (FTP) Status and Further - Comments", RFC 414 (NIC 12406), MIT-Project MAC, 20 November 1972. - - Braden, Bob, "Comments on File Transfer Protocol", RFC 430 - (NIC 13299), UCLA/CCN, 7 February 1973. - - Thomas, Bob, and Bob Clements, "FTP Server-Server Interaction", - RFC 438 (NIC 13770), BBN, 15 January 1973. - - Braden, Bob, "Print Files in FTP", RFC 448 (NIC 13299), UCLA/CCN, - 27 February 1973. - - McKenzie, Alex, "File Transfer Protocol", RFC 454 (NIC 14333), BBN, - 16 February 1973. - - -Postel & Reynolds [Page 66] - - - -RFC 959 October 1985 -File Transfer Protocol - - - Bressler, Bob, and Bob Thomas, "Mail Retrieval via FTP", RFC 458 - (NIC 14378), BBN-NET and BBN-TENEX, 20 February 1973. - - Neigus, Nancy, "File Transfer Protocol", RFC 542 (NIC 17759), BBN, - 12 July 1973. - - Krilanovich, Mark, and George Gregg, "Comments on the File Transfer - Protocol", RFC 607 (NIC 21255), UCSB, 7 January 1974. - - Pogran, Ken, and Nancy Neigus, "Response to RFC 607 - Comments on the - File Transfer Protocol", RFC 614 (NIC 21530), BBN, 28 January 1974. - - Krilanovich, Mark, George Gregg, Wayne Hathaway, and Jim White, - "Comments on the File Transfer Protocol", RFC 624 (NIC 22054), UCSB, - Ames Research Center, SRI-ARC, 28 February 1974. - - Bhushan, Abhay, "FTP Comments and Response to RFC 430", RFC 463 - (NIC 14573), MIT-DMCG, 21 February 1973. - - Braden, Bob, "FTP Data Compression", RFC 468 (NIC 14742), UCLA/CCN, - 8 March 1973. - - Bhushan, Abhay, "FTP and Network Mail System", RFC 475 (NIC 14919), - MIT-DMCG, 6 March 1973. - - Bressler, Bob, and Bob Thomas "FTP Server-Server Interaction - II", - RFC 478 (NIC 14947), BBN-NET and BBN-TENEX, 26 March 1973. - - White, Jim, "Use of FTP by the NIC Journal", RFC 479 (NIC 14948), - SRI-ARC, 8 March 1973. - - White, Jim, "Host-Dependent FTP Parameters", RFC 480 (NIC 14949), - SRI-ARC, 8 March 1973. - - Padlipsky, Mike, "An FTP Command-Naming Problem", RFC 506 - (NIC 16157), MIT-Multics, 26 June 1973. - - Day, John, "Memo to FTP Group (Proposal for File Access Protocol)", - RFC 520 (NIC 16819), Illinois, 25 June 1973. - - Merryman, Robert, "The UCSD-CC Server-FTP Facility", RFC 532 - (NIC 17451), UCSD-CC, 22 June 1973. - - Braden, Bob, "TENEX FTP Problem", RFC 571 (NIC 18974), UCLA/CCN, - 15 November 1973. - - - - -Postel & Reynolds [Page 67] - - - -RFC 959 October 1985 -File Transfer Protocol - - - McKenzie, Alex, and Jon Postel, "Telnet and FTP Implementation - - Schedule Change", RFC 593 (NIC 20615), BBN and MITRE, - 29 November 1973. - - Sussman, Julie, "FTP Error Code Usage for More Reliable Mail - Service", RFC 630 (NIC 30237), BBN, 10 April 1974. - - Postel, Jon, "Revised FTP Reply Codes", RFC 640 (NIC 30843), - UCLA/NMC, 5 June 1974. - - Harvey, Brian, "Leaving Well Enough Alone", RFC 686 (NIC 32481), - SU-AI, 10 May 1975. - - Harvey, Brian, "One More Try on the FTP", RFC 691 (NIC 32700), SU-AI, - 28 May 1975. - - Lieb, J., "CWD Command of FTP", RFC 697 (NIC 32963), 14 July 1975. - - Harrenstien, Ken, "FTP Extension: XSEN", RFC 737 (NIC 42217), SRI-KL, - 31 October 1977. - - Harrenstien, Ken, "FTP Extension: XRSQ/XRCP", RFC 743 (NIC 42758), - SRI-KL, 30 December 1977. - - Lebling, P.

-
-

FtpCallbackOptions is declared as follows.

-
-typedef struct FtpCallbackOptions {
-    FtpCallback cbFunc;		/* function to call */
-    void *cbArg;		/* argument to pass to function */
-    unsigned int bytesXferred;	/* callback if this number of bytes transferred */
-    unsigned int idleTime;	/* callback if this many milliseconds have elapsed */
-} FtpCallbackOptions;
-
-

PARAMETERS

-
-
opt
-
The address of a structure that contains a pointer to the callback - function and the criteria for calling it.
-
nControl
-
A handle returned by FtpConnect() -or FtpAccess().
-
-

DESCRIPTION

-

FtpSetCallback() establishes a callback functions and tells FTPlib - when to call it. A data connection inherits the options assigned to - the control connection it is created from. Callbacks are only called - on file data connections.

-

The fields in FtpCallbackStruct are described below.

-
-
cbFunc
-
Specifies the address of a user callback routine.
-
cbArg
-
Specifies an argument to pass to the user's callback -routine.
-
idleTime
-
Specifies the socket idle time in milliseconds that triggers -calling the user's callback routine.
-
bytesXferred
-
Specifies the number of bytes to transfer between calls to the -user's callback routine.
-
-

The user's callback routine is specified as:

-
-typedef int (*FtpCallback)(netbuf *nControl, int xfered, void *arg);
-
-nControl is the data connection in use. xfered specifies -how many bytes of data have been transferred on the -connection. arg is the value passed in the FtpCallbackOptions -field cbArg. -

The user can request to be called back on either of two -events.

-

If the routine should be called when the data socket is idle for -some period of time, pass the number of milliseconds of inactivity -that should trigger a callback in the idleTime field.

-

If the routine should be called when a certain amount of data has -been transferred, specify a non-zero value in bytesXferred. This -value represents the minimum number of bytes to transfer between -callbacks. When using this option, ftplib keeps track of the number of -bytes transferred and calls the user once the specified number of -bytes or more has been transferred. It then resets the count to 0 and -starts again.

-

If the user wishes to continue the transfer, the callback -routine should return true (non-zero). It can abort the transfer by -return zero.

-

RETURN VALUE

-

Returns 1 for success or 0 for failure.

ftplib

- -

ftplib is a set of routines that implement the FTP protocol. They -allow applications to create and access remote files through function -calls instead of needing to fork and exec an interactive ftp client -program.

- -

ftplib has been built and tested on Linux (X86) and OpenVMS (AXP).

qftp

-

qftp is a utility that performs file transfers using -ftplib based on instructions presented on the command -line.

-

Format

-
-    qftp <action> <host> [ -l user [ -p pass ] ] { options/files }...
-
-    Actions: send, get, dir, list, rm
-
-    Options:
-        -v level        Set verbosity
-        -r rootpath     Change remote working directory
-        -m umask        Set umask for created files
-        -a | -i         Set ascii/image transfer mode
-        -w              Toggle wildcard mode
-        -s cmd          Send cmd as a SITE command
-        -b              Toggle stripping of path from filename
-                        on send
-
-
-
action
-
Specifies what qftp is to do. qftp can -send files to a remote system, get files from a -remote system, remove (rm) files from a remote system, or -retreive a directory of files or a list of files on a -remote system.
-
host
-
Specifies the name of the remote system. An alternate port may -be specified by appending a colon and the port name or number to -the host name.
-
-l user
-
Specifies the username to log in with on host.
-
-p pass
-
Specifies the password to log in with on host. -

If user is not specified, qftp will use -anonymous. If pass is also not specified, qftp -attempts to build a password from the translation of the -environment variable "USER" and the string returned by -gethostname() separated by an "@".

-
-
-v level
-
Specifies the verbosity level. A level of 1 will cause -qftp to display messages indicating successful transfers. A -level of 2 will cause FTP protocol responses to be displayed. A -level of 3 will cause FTP protocol commands to be displayed.
-
-r rootpath
-
Sends a 'change directory' request to the remote server. All -subsequent file names on the command line will be parsed relative -to this new directory.
-
-m umask
-
Sends a request to change the umask to the remote server. This -may not be supported by all servers. It is implemented using the -'SITE' command in the FTP protocol.
-
-a
-
Requests that subsequent files be sent in ascii mode.
-
-i
-
Requests that subsequent files be sent in image mode.
-
-w
-
Toggles handling of filenames to get as wildcards. When a - wildcard filename is encountered it is passed to the server in a - NLST (brief directory) command. qftp will save the list of files - returned and then retrieve each file individually.
-
-s cmd
-
Sends cmd in a SITE command. This can be useful to alter the way - filenames are presented. For example, an OpenVMS FTP server will - strip version numbers from file names after receiving a 'SITE UNIX' - command.
-
-b
-
Toggles stripping of paths from filenames on send. By default, - qftp passes the full path of the input file as specified on the - command line to the remote FTP server as the target filename. This - option will cause qftp to send only the basename of the file.
-
-

qftp reads the command line argument by argument and acts on - each as it comes to it. Most options only change the value of a - variable. The '-m' (umask), '-s' (site), and '-r' (change - directory) options are executed immediately by sending the command - to the server. The '-a' (ascii) and '-i' (image) options save the - type for subsequent transfers. When a filename is encountered it - is sent to the server with the command for the selected action.

-

It is possible to send multiple files with different modes on the - same command line. For example, the following command will send all - text files in ascii mode and all zip files in image mode:

-
-    qftp send srvr -a *.txt -i *.zip
-
-

qftp may optionally be invoked through a softlink. -qftp searches the command which invoked it for 'send', 'get' -or 'dir' and, if found, performs the requested function. In this -case, leave off the action argument on the command line.

-

For example; create the following softlinks:

-
-    ln -s qftp ftpsend
-    ln -s qftp ftpget
-    ln -s qftp ftpdir
-    ln -s qftp ftplist
-    ln -s qftp ftprm
-
-

and then invoke transfers with 'ftpsend' instead of 'qftp send', -etc.

-

If no file names are specified on the command line, qftp -will read file names from stdin. Use your favorite utility to -generate a list of files to send/retreive or type them -interactively.
