1. Start PuTTY by double-clicking its icon
2. When a PuTTY Configuration window opens select Session (it should be selected by default) from the Category panel on the left. In the Host Name (or IP address) field enter the name of the computer you wish to connect to. In the Port field input 22 ( which is the default) 31415 is only an example. Make sure that SSH is selected under Protocol (it should be selected by default). Click on Open.
3. In the new dialog box enter your username and password.
4. Once you see the prompt, you are connected to your server.
