I want to disable certain users from telneting into a
RedHat Linux 5.1 machine altogether, is this possible?
Actually disabling certain users from using ftp, rsh,
rlogin, and anything else would be cool too.

Bryan,

Look at:

$man 5 hosts_access

to start...

Al,
        Thanks for the response, and I did learn alot about
hosts.allow and hosts.deny, but what I actually wanted to do
was deny service to specific accounts on the server
machine.  So that whenever the user steve (on the server
machine) tried to telnet in, it wouldn't let him no matter
where he was coming from.  I think I've got a solution, by
putting the default shell as /dev/null the user can't
telnet, rsh, or ftp, but IMAP and pop seem to work fine.
Thanks for your help.

1. telnet security

Probably I'm just plain stupid, but I cannot telnet from a client to our
5.0.4 server unless I have an entry in the server's /etc/hosts file for the
client.  Is this normal, or is there some setup I don't know about?

Thanks

Roger
