Here are a couple things.

First /etc/rc.d/init.d/telnetd stop
Next rpm -e telnet-server
Next Install SSH

Also, just a personal opinion....While the thought of having custom error
messages for failed logon attempts, and failed port connection attempts
might sound cool and fun now....chances are that eventually you're going to
end up pissing someone off to the point that they will wait and watch until
a new exploit comes out and nail you just because you hurt their feelings.
I'm saying that it's right, or that it's justified, just that it's probably
true. When you tell someone they can't do something, they become far more
determined to do so.

That's just my .02 cents.

Subject: Custom messages for failed ROOT logins on RedHat

Hi, just curious if its possible to get PAM or TCP Wrappers... or anything
else for that matter, to give me a custom error message, like:
  "go away & stop trying to login as root"
When idiots try telnetting into my box. I know its possible to use TWIST
with tcpd, but i dont want it to be host based! I just want it to happen
when someone from any address tries to login as root.
Is it possible to get PAM to return custom error messages??
Any help/suggestions/flames appreciated
