File Forwarding in Fidonet Technology Networks
|
|
Robert Williamson FidoNet#1:167/104.0 robert@ecs.mtlnet.org
|
|
|
|
Purpose:
|
|
To document current practices in File Forwarding and the minimum
|
|
requirements and known extensions of the TIC file format.
|
|
|
|
Acknowledgements:
|
|
The TIC file format was introduced by Barry Geller, in the MSDOS
|
|
File Forwarder, Tick. Useful extensions to this format were introduced
|
|
by Harald Helms, in the MSDOS FileForwarder, AllFix.
|
|
|
|
Terminology:
|
|
FTN - Fidonet Technolgy Network, such as FIDONET, AMIGANET or IBMNET.
|
|
Sometimes used interchangably with the term DOMAIN.
|
|
|
|
FNC - FileName Conversion, process of converting filenames to msdos 8.3
|
|
format for transmission.
|
|
|
|
FQFA - Fully Qualified FTN Address, the format is
|
|
FTN#Zone:Net/Node.Point
|
|
|
|
CRC - Cyclic Redundancy Check, method to determine whether some data
|
|
has been altered. CRC-32 is used in File Forwarding.
|
|
|
|
TIC - a file that contains control information for the File Forwarding
|
|
system. These files are named xxSTAMP.TIC, where xx is an
|
|
abbreviation representing the File Forwarding program name and
|
|
stamp is a unixdate stamp truncated to 6 characters.
|
|
|
|
UTC - Universal Time Coordinated, the time at the 0o meridian
|
|
(Greenwich); previously called GMT
|
|
|
|
|
|
forwarding - the process of creating and sending tic files and the
|
|
associated file to one's downlinks.
|
|
|
|
ticking - the processing of reading and verifying a tic file and it's
|
|
associated file.
|
|
|
|
hatching - the process of introducing a new file into a fileecho
|
|
|
|
cross-hatching - the process of forwarding a file from one fileecho
|
|
(ususally restricted) to another
|
|
|
|
Associated File - The file listed in the FILE field of the TIC file.
|
|
|
|
|
|
Note that use of UPPERCASE on tic file keywords in this document in
|
|
for display purposes only.
|
|
|
|
Format of a TIC file:
|
|
|
|
Addressing:
|
|
In a tic file any form of FTN address representation from 3d to
|
|
FQFA may be used. All File Forwarders must understand the
|
|
following formats:
|
|
zone:net/node - 3D
|
|
zone:net/node.point - 4D
|
|
zone:net/node@ftn - 5D - point 0 assumed
|
|
zone:net/node.point@ftn - 5D
|
|
ftn#zone:net/node.point - fqfa
|
|
|
|
File Forwarders should have configurable options per site as to the
|
|
type of addressing each of it's downlinks can understand.
|
|
|
|
Dates:
|
|
All dates are expressed in UTC.
|
|
|
|
TimeDateStamps:
|
|
All TimeDateStamps are unix TimeDateStamps (# of seconds since Jan
|
|
1, 1960) in UTC and expressed in hexadecimal notation.
|
|
|
|
Case Insensitivity:
|
|
the format is completely case-insensitive. It is general practice
|
|
that the first letter of a keyword is uppercase. This is not a
|
|
requirement.
|
|
|
|
Order Dependancy:
|
|
keywords are not order dependant.
|
|
Order dependancy is required in some groupings of a keyword, such
|
|
as PATH, VIA, DESC and APP.
|
|
|
|
Modification of address fields on PassThrough:
|
|
The forwarding site may modify the addresses in any keyword field
|
|
to make them compliant with the addressing limitations of each
|
|
downlink.
|
|
|
|
Stripping of SeenBys:
|
|
The forwarding site may strip seenbys to current FTN, ZONE or NET,
|
|
when not forwarding outside of current FTN, ZONE or NET. This does
|
|
not imply nor permit the stripping of of a direct downlink which is
|
|
outside the current strip filter.
|
|
|
|
|
|
Keywords:
|
|
There are no colons on keywords.
|
|
|
|
Each keyword line is terminated with CR LF pair.
|
|
|
|
The maximum length of a keyword line is 256 characters, including the
|
|
CRLF termination. Some keyword lines may have a shorter limit.
|
|
|
|
Keywords are separated from their data by a single space. There is
|
|
no space if there is no data associated with the keyword.
|
|
eg: ReturnReceipt
|
|
|
|
Keywords are case-insensitive and order independant.
|
|
|
|
Keywords not understood are to be passed-though.
|
|
|
|
Known Keywords that are blank should not be passed though.
|
|
For example, an empty AREADESC, could be either dropped or the
|
|
blank replaced with the proper description.
|
|
|
|
Most Keywords are passed through when processing.
|
|
There are exceptions. In some cases, a site-specific replacement
|
|
may be created.
|
|
Keywords marked with a ^ should not be passed-through.
|
|
|
|
Keywords marked with a * are REQUIRED when processing a TIC file.
|
|
If any of these are missing, the tic file should be considered as
|
|
BAD and the associated file not forwarded to downlinks.
|
|
|
|
Keywords marked with a # are CREATED when hatching or forwarding.
|
|
|
|
|
|
*# AREA [AreaName]
|
|
the TagName of the file area.
|
|
|
|
AREADESC [description of area] OPTIONAL
|
|
a short (80 chars) description of the file area. This could be
|
|
the description found in FileBone.NA
|
|
|
|
*# FILE [File being sent]
|
|
the name of the file being sent, no path
|
|
the filename must conform to msdos 8.3 format, unless it is known
|
|
that the receiving site can handle longer filenames.
|
|
|
|
^# FULLNAME [original filename before FNC] OPTIONAL FNC only
|
|
the original filename (no path) before FileName Conversion
|
|
|
|
*# CRC [CRC-32 in hex]
|
|
crc of the file being sent, 8 hexadecimal characters
|
|
|
|
^ MAGIC [MagicName] OPTIONAL
|
|
Name under which the file can be FREQed from the site listed in
|
|
FROM. This is NOT passed though when forwarding, unless the
|
|
MAGIC name is the same on the forwarding site. It can be
|
|
replaced by the appropriate name.
|
|
|
|
REPLACES [FileName] OPTIONAL
|
|
Filename (no path) of a file hatched in the AREA that the
|
|
associated file replaces. If the site expects FNC files, and the
|
|
filename does not confrom to msdos 8.3 convention, the REPLACES
|
|
name should also be FNC.
|
|
|
|
# DESC [Description]
|
|
Description of the file, limited to 80 characters per line,
|
|
including CRLF termination.
|
|
If multiple LDESC lines are used, the DESC line must provide the
|
|
maximum information. No File Forwadrer is required to passthough
|
|
or make use of any extra DESC line after the first.
|
|
|
|
# LDESC [multiple lines]
|
|
A long description of the file. LDESC does NOT replace DESC, it
|
|
is used IN ADDITION to the short description. No File Forwarder
|
|
is required make use of LESC lines.
|
|
|
|
# SIZE [Bytes] OPTIONAL, SHOULD be required
|
|
Length of the file in bytes
|
|
|
|
DATE [TimeDateStamp]
|
|
TimeDateStamp of the file. Can be date of creation of archive.
|
|
|
|
RELEASE [TimeDateStamp]
|
|
Date when file is TO BE released. Usually used by SDS, but can
|
|
be used by ADS as well.
|
|
|
|
AUTHOR [name]
|
|
Name of the author of the software package being hatched. This
|
|
field is obviously not applicable to Newsletters, Nodelists and
|
|
Diffs and the like.
|
|
|
|
SOURCE [authors_address]
|
|
FTN address of the Author of the software package being hatched.
|
|
Not necessary the same as the ORIGIN hatch site. Does not have
|
|
to be an FTN address.
|
|
|
|
^ APP [program] [Application Specific Information]
|
|
The APP keyword is a keyword known to programs of the name
|
|
indicated. APP'S are order dependent and must be passed though.
|
|
|
|
*# ORIGIN [Address]
|
|
Site where file entered the fileecho
|
|
|
|
*^# FROM [Address] [Pwd]
|
|
Site that is forwarding the file to the next site. Pwd is
|
|
optional and rarely used, IF AT ALL. Pwd is NEVER passed through.
|
|
|
|
^ TO [Address] OPTIONAL
|
|
Site to which this TIC and the assocaited file are being sent.
|
|
This keyword is included in the .TIC file when:
|
|
a) the file is being routed via another system which permits
|
|
such routing.
|
|
b) the platform in use does not have any FTN software
|
|
independant method of associating a file nd it's
|
|
destination. eg. platforms that do not have filenotes
|
|
that could contain this information as part of the
|
|
filesystem.
|
|
|
|
If the address in the TO line is that of the receiving site, the
|
|
field is not passed through when forwarding. If the address in
|
|
the TO lines IS NOT that of the receiving site, it should be
|
|
forwarded to the TO site, if a routing agreement is in place with
|
|
the sending site.
|
|
|
|
*^# CREATED [by] [Program Banner]
|
|
File Forwarder which created the TIC file. This is generally in
|
|
the form:
|
|
Created [by] program_name version [copyright_info]
|
|
|
|
VIA [FROM CREATED] OPTIONAL (tracking)
|
|
Copy of CREATED line of FROM, with 'Created [by]' stripped and
|
|
FROM prepended. Always passed though. The VIA is only created
|
|
by the receiving site when forwarding. It is never created by the
|
|
hatching site. Therefore, in any TIC file, the addresses in the
|
|
FROM and VIA should never be the same.
|
|
examples:
|
|
Via 1:167/100 ALLFIX+ 4.31 Copyright (C) 1992,95 Harald Harms (2:281/910)
|
|
Via FIDONET#1:167/104.0 XTick 3 Copyright (c) 1995 Robert Williamson FIDONET#1:167/104.0
|
|
|
|
*# PATH [Address] [TimeDateStamp] [date and time]
|
|
Address of Site which has forwarded the file. TimeDateStamp,
|
|
date and time is that of when the Site received and Processed the
|
|
file.
|
|
|
|
* # SEENBY [Address]
|
|
Site which has received the file. There are multiple lines of
|
|
Seenby and they are unordered.
|
|
|
|
* PW [password]
|
|
Site or Area password. This is case-insensitive and should be at
|
|
least 5 characters in length.
|
|
|
|
PGP [signature]
|
|
PrettyGoodPrivacy signature. To be discussed.
|
|
|
|
^ ReceiptRequest -no data- OPTIONAL
|
|
A request to the receiving system to generate a IsReturnReceipt
|
|
(attribute word bit 13) messsage, in the same manner it would if
|
|
it had received a message with the FileAttach an ReturnReceipt
|
|
attributes and a subject of the filename.
|
|
There is NO requirement to recognize this keyword. It should
|
|
never be passed through.
|
|
|
|
Transmission of Files:
|
|
|
|
The associated file, that is, the file Listed in the FILE field of the
|
|
TIC file, should always be sent FIRST. In the case of a failed session,
|
|
sending the FILE first prevents the orphaning of the file that is
|
|
normally caused by the deletion or movement of the TIC file to BAD.
|
|
|
|
File Forwarders should not move or delete orphaned TIC files, but this
|
|
can neither be relied upon nor mandated.
|
|
|
|
File Forwaders should be transparent to the renaming of file by
|
|
mailers. This means that if the mailer renames a duplicate file by
|
|
renaming or bumpinmg a numeric extension, the File Forwarder should be
|
|
able to use the size and crc fields of the TIC to find and properly
|
|
rename the associated file referred to in the TIC.
|
|
|
|
File Forwaders should always delete and dequeue unsent TIC files when
|
|
re-hatching the same or updated version of an associated file. The
|
|
implementor may wish to allow exceptions for periodicals such as
|
|
nodediffs and newsletters.
