How To Add a Welcome Message for SSH Users
Here is a quick tip on how to add a welcome message for your SSH users.
If you want users to see a banner welcome message when connecting to your SSH server, you need to turn on the banner configuration of SSHd and then create a banner file.
Step 1:
Create a banner file that contains text you want people to see when connecting to your SSH server.
Create and open the banner file:
# vi /home/userid/banner
Add your text:
*****************************************************************
*This is a private SSH service. You are not supposed to be here.*
*Please leave immediately. Your information has *
*been logged and a report has been emailed to the admin *
*concerning your unauthorized attempts. *
*****************************************************************
Write the file and quit:
:wq
Step 2:
Edit sshd_config to set a default banner path.
# vi /etc/ssh/sshd_config
then add the following to the config file:
Banner /path/to/banner
Write the file and quit:
:wq
Step 3:
Restart the sshd server.
# /etc/init.d/sshd restart
Step 4:
SSH to your server and test to see if the banner is working:
# ssh user@xxx.xxx.xxx.xxx
*****************************************************************
*This is a private SSH service. You are not supposed to be here.*
*Please leave immediately. Your information has *
*been logged and a report has been emailed to the admin *
*concerning your unauthorized attempts. *
*****************************************************************
And it works :)
