Banner for SSH Login

[Trevor]

I would like for all users, that login to my system via ssh,
to see the following message before seeing the login
prompt:   

                'You are on sacred ground!'

What are the steps to configure my Linux system to achieve
this?

I would go in this way:

1. Create the ssh banner file (e.g. /etc/ssh/my_ssh_banner)
2. Create the customized ssh config file for the ssh configuration into the path /etc/ssh/sshd_config.d/ (e.g. my_custom_banner.conf)
3. In the my_custom_banner.conf specify the option "Banner /etc/ssh/my_ssh_banner"
4. Reload SSH daemon
5. Open a new ssh session, you should find the new banner (:

rhnoname,

Your directions/instructions were short, sweet, and 
to the point.  Most importantly, they worked!!!

Many thanks for your response!

As an admin go to the server's ssh config file : vim /etc/ssh/sshd_config and do the following addition :

then insert the banner text into the mentioned file path and restart the sshd service.

That's it , you are now king of the ssh banners !
