Ugh ... you shouldn;t use telnet, it's horrible insecure because it transmits passwords in plain text. Use SSH instead. If you really must continue to use telnet the banner is in /etc/issue.net (you may also need to change /etc/issue as well).

I am not sure how you'd change from keverized to non-keberized telnet. Doesn't the krb5-telnet drop back to normal telnet behavior if keberod is not configured?
