If you are running your own server I’m sure you’ve thought about setting your own login banner for SSH connections. This can be handy to post any important information such as service notices or a legal warning before a user logs in. You can see a sample login banner below in this screen shot.

This is extremely easy to setup

Step 1: Login in as root and navigate to “/etc/ssh”.

Step 2: create a file named “sshd-banner” using your editor of choice.

Step 3: create your banner content and save the file.

Step 4: open “sshd_config” for editing.

Step 5: Add the following line to your config file “Banner /etc/ssh/sshd-banner” and save.

Step 6: Restart the sshd server. On a linux server this would be “/etc/init.d/sshd restart”

Feel free to log back into your server to test.
