How to set SSH welcome message and Banner?
To change the message displayed before login, edit /etc/ssh/sshd_config :
$ sudo vi /etc/ssh/sshd_config
and add (or uncomment) the line
Banner /etc/banner
/etc/banner can be whatever file you want. Then edit /etc/banner
$ sudo vi /etc/banner
and put in whatever welcome message you want:
. | . . . .-. | .-..-. .--.--. .-. \ \ / (.-' |( ( )| | |(.-' `' `' `--'` `-'`-' ' ' ` `--'
You’ll probably need to restart sshd before your changes take effect:
$ sudo /etc/init.d/ssh restart
# systemctl restart sshd.service
To change the message displayed after login, edit /etc/motd :
sudo vi /etc/motd
and enter the message you want to display.
:wq
