How to use PuTTY


PuTTY can be used to connect from a Windows-based computer to other computers through SSH as well as other protocols. This instructions will help you utilize PuTTY so that you can connect to the CS network with ease.


Go ahead and open PuTTY. You will be presented with a configuration screen. There are things that you need to know before we get too far into PuTTY.

Host Name (or IP address)

The Host Name box is where you will enter in the server’s hostname (or IP address). If we wanted to connect to, we would insert into the input box.


The port that you choose will, for the vast majority of the time, be 22 (the SSH port).


The protocol that you will be using for the vast majority of the time is SSH. You need not worry yourself with raw protocol; if you are so inclined, you may read up on it in PuTTY’s user manual.

Load, Save or Delete a stored Session

For your convenience, you can save session connection information. First, enter in an appropriate hostname and a savename (TIP: You can enter username@hostname to prevent the username prompt from appearing after the connection is established). Now click “Save”. When you want to recall your custom session, then click on the savename and then click “Load”.

Close Window on Exit

This is more of a personal preference than anything; “Always” means that if your session closes, then PuTTY will close, too. “Never” is the reverse of that: PuTTY will not close when your session closes. “Only on clean exit” means that PuTTY will close if the session that you were running doesn’t blow up or end abnormally.
