redhat - security banner for rlogin

How do I display a security banner before the rlogin prompt?

I currently use /etc/issue for telnet and ssh.

Thanks.

If you mean "after" a successful login, you can put your message in the /etc/motd.

I mean before the user logs in: (i can do it on a HP-UX server)

rlogin servername -l userid

UNAUTHORIZED USE AND/OR ACCESS IS STRICTLY PROHIBITED

You can apply banners to rlogin using the
TCPwrappers program.

Check out the following link:

It is not so easy but it works!

Check out /etc/issue.net and the banner function of OpenSSH.
