> Assuming your network is operating properly, there's a couple things you
> need to look for within Red Hat.

> First, this version of RH may have packet filtering enabled to stop
> telnet access.  I believe you can easily test this theory by issuing the
> command (as root) /etc/rc.d/init.d/ipchains off.  If it gives an
> affirmative response that it turned it off, then you know you're not
> hampered by any packet filtering for the next test.

> Next, once we've determined that there's no packet filtering, open up a
> terminal window and telnet to localhost.  If that fails, then your inetd
> or xinetd super-server is not configured for telnet and/or you haven't
> installed the telnet server rpm.  If you have installed the rpm, it will
> write the appropriate entries into inetd or xinetd and all you need to
> do is enable them and restart the super-server.
