I am new to this forum, and have a qury regarding port number. I am using a cisco router(don't know model number) at our workplace and need to know the port number that is used by telnet application. I am getting error that Telnet can't make session as port:23 is not there...but when I checked NETSTAT, I didn't get any port number like 23. Infact, I amnot sure that port 23 is at all in use.
Could anyone can help me checking which port is being used by Telnet as default, and how can we check that ??
Many thanks in advance,
