SSH Logins with Banner Messages (MOTD File)

One of the easiest ways to protect and secure SSH logins is by displaying warning messages to unauthorized users or displaying welcome or informational messages to authorized users.

There are two ways to display messages one is using the issue.net file and second one is using the MOTD file.

issue.net : Display a banner message before the password login prompt.

motd : Display a banner message after the user has logged in.

 # vi /etc/motd 

:: After executing the above command, a configuration file will open now you need to past what continent you want to display on the server login screen.
