Creating a SSH Warning Banner

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 😀
