Warning Message on ssh terminal login - Banner

We can set a warning or a company message to be displayed when ever users login to their ssh account.

For this we have to create file and save our message in that file.

Example:

Now point edit the ssh config (it may be in /etc/ssh/sshd_config) and uncomment the line with Banner in it and change it to point the waring message file

save the file and restart ssh.
