Disable Telnet Login with message?

I'm wondering if anyone has any thoughts on how to disable telnet logins,
but display a message that says "please use ssh".



telnet to ssh migration...



I'm using xinetd with telnet, I've tried setting the instances=0 in
/etc/xinetd/telnet with the message in /etc/issue.net but it didn't' work as
expected.



Any ideas?
