To create warning banner, so whenever anyone attempts to SSH onto your server they will be greeted with a message.
1.Edit the /issue.net file
sudo nano /etc/issue.net
2. Enter your message:
------------------------------------------------------------------------------- I am such a hero, as I've got this to work XD Although Access is limited to Authorized Individuals If you are not Authorized please disconnect ASAP!! All actions are recorded and monitored! --------------------------------------------------------------------------------
3. You will need to update, the ssh daemon configuration file
sudo nano /etc/ssh/sshd_config
4. Look for this line that starts with Banner, and delete the #. The should look like this:
Banner /etc/issue.net
5. Restart the ssh daemon
sudo service ssh restart
When next login you will be prompted with the message that you just wrote 😀
