telnet on port other than 23

[scottyb]

Is it possible to have an AIX 4.1.x machine accept ip connections such as
Telnet or FTP on any port other than the standards of 23 and 21 ?

If so, is it difficult to configure ?

Thanks -

Telnet is a little bit tricky, because the telnet client looks at which
port you are connecting to and if it is not 23 it will turn off
capability negotiation and run in "stupid"-mode (it will not be
full-function telnet).

You can run a telnetd on any, and as many ports as you like by hacking
inetd.conf, but you will only get true telnet on port 23 unless you have
a non-standard client.

Yes. You can define a new service, called "telnet2" for example, in
/etc/services, listening on another tcp port. Then, in
/etc/inetd.conf, copy the default "telnet" line to a new line and
rename the service to "telnet2."

Of course. Put two entries into /etc/inetd.conf, one for each port.
