SSH Logins with Banner Messages (Issue.net)

One of the easiest ways to protect and secure SSH logins is by displaying warning messages to UNauthorized users or display 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/issue.net  

:: Now Paste the below command or any command you want to display on the server login screen then save the file and exit.

 # vi /etc/ssh/sshd_config  

Use above command to edit the ssh configuration file, now we have to find “Banner” comment on this file then untag it and give the following path display banner on ssh connection

Banner /etc/issue.net

:: Now we need to restart the ssh service in our system, use below command in centos 7 to execute the same.

 # systemctl restart sshd.service 

:: Now I need to check the server banner with new ssh connection.

Yeah! We got the notification message while login into the server.

Thank You...
