+====Logging in for the First Time====
-The new system is running [[quick:os|CentOS]] 7.3 and uses the //Bash// shell by default.
+:!: You will use a password only for the **first time** you log in using ssh. And the first step will be to set up your ssh key.  After this, you **can only log in using ssh keys and your password will be disabled.**
-You should change your password after logging in the first time.
+Please read carefully and follow the procedure to set up your [[guide:sshkeys|ssh keys]] for your first login [[guide:sshkeys|here]].
-To change your password, use the ''passwd'' command.
-Rules are: 10 characters, with at least one of the following character types: upper and lower case, numbers, and special characters.  Use ssh keys wherever possible.
-Once you have logged in, give some consideration to how you will be using your session on the login node.  If you are going to spend a long time logged in, doing a variety of tasks, it is best to get yourself [[http://wiki.chpc.ac.za/quick:start#example_interactive_job_request|an interactive PBS session]] to work in.  This way, if you need to do something demanding, it will not conflict with other users logged into the login node.
