Hi all,
For a long time I had our bbs set up so that incoming telnet
connections would bring up a NODE response instead of the
standard TELNET login. I had set this up by making the entries
in /etc/services as follows:
telnet 24/tcp
node 23/tcp
It worked fine until I upgraded the machine to RedHat 5.2. After that,
telnet originating from the machine would try to access port 24 on the
distant machine. It seems the telnet software on our box now checks
/etc/services to see what port it should be using instead of assuming
that it should be 23.
Richard's suggestion of calling the non-standard telnet port something
different looks like it might overcome my problem, but it might also
leave /etc/services with no entry labelled "telnet". Does anyone know
what really happens and whether the lack of any "telnet" entry will
cause problems?
