Configuring an SSH banner on Debian
Note: I’ve since come up with something much better, which dynamically generates the content. You can see it in the post: Debian/Ubuntu: Dynamic MOTD.
Configuring a “Welcome Banner” is a great way to notify your users about the machine they are about to login to. I personally use this to inform the user of the IP, Hostname, OS version and someone to contact.
Edit the file under “/etc/motd”.
Change this to something informative such as the below:
========================================
= Welcome to Hitchcock =
= IP: 10.10.10.10 =
= Hostname: hitchcock.example.com =
= OS: Debian 5.01/Lenny =
========================================
Just a short one this, but useful to know.
