As others have said, ssh is a better option for most--but not all--uses.
Well.. first, from the box running the telnet daemon, try to telnet to
the loopback address (127.0.0.1), and if that doesn't work, then it's
most likely that the telnet daemon isn't running (in.telnetd won't be
running in most cases, because inetd is handling that port.
Check to see that the telnet line in /etc/inted.conf isn't commented out.
grep "^telnet" /etc/inetd.conf
Check to see if inetd is running.
ps aux | grep inetd | grep -v grep
Check that someone/something is listening on that port.
netstat -a | grep LISTEN | grep telnet
If those check out, then it gets uglier...
Check /var/log/messages for error starting inetd/telnetd.
Check your routing tables.
If you're using IP Masquerading or ipchains, check your input and output
Hmm.. that's all I can think of off the top of my head.
