Now give the messages that you want to see when you are logging to the server.
For eg : This computer system is for authorized users only.
Save the file and test the case by logging in to a new SSH session
How to increase /tmp space on live server

pstree -p | grep tailwatchd
kill -9 < process ID>
You may need to copy the /tmp to backup
