<H3>Synopsis.</H3>
<P>
<code><strong>mbtelnetd</strong></code>
<P>&nbsp;<P>
<H3>Description.</H3>
<P>
<strong>mbtelnetd</strong> is a small proxy that handles incoming telnet/vmodem
sessions and calls mbcico via the network on the standard fido port (60179).
This small proxy was original written by Vadim Zaliva, lord@crocodile.kiev.ua, Serge
Terekhov, 2:5000/13@fidonet and Vadim Kurland, vadim@gu.kiev.ua for the ifmail
package.
<P>
<P>&nbsp;<P>
<H3>Installation</H3>
<P>
To accept incoming telnet sessions to allow the ITN nodelist flag you must
install <b>mbtelnetd</b> in your system. You need to do this as root. The
example shown is for most GNU/Linux distributions.
Add the following line to <code>/etc/services</code>:
<pre>
tfido 60177/tcp
</pre>
Add the following line to <code>/etc/inetd.conf</code>:
<pre>
tfido stream tcp nowait mbse /opt/mbse/bin/mbtelnetd mbtelnetd
</pre>
Or add the following lines to <code>/etc/xinetd.d/mbsebbs</code> if your system
uses xinetd instead of inetd:
<pre>
service tfido
{
socket_type = stream
protocol = tcp
wait = no
user = mbse
instances = 10
server = /opt/mbse/bin/mbtelnetd
}
</pre>
