To create a new key pair, select the type of key to generate from the bottom of the screen using RSA with 4096 bit key size is good for most people. There is rarely any need to change it from the default value of Only on clean exit. Select a profile and click Delete to delete a profile that’s no longer needed.įinally, the Close window on exit setting specifies whether the terminal window should be automatically closed when the connection is terminated. Select a profile and click Load to use a previously saved profile. Profiles you save will be included there. Initially it will contain just Default Settings. Saved profiles appear in the larger box below it. The host name and your other settings are saved in the profile. Just write the name of your new profile in the Saved Sessions box and click Save to create a new profile. This section allows you to save your settings as named profiles. SSH is a secure, encrypted communications protocol designed to ensure your password and data are maximally protected. The Connection type selection seldom needs to be touched. If for some reason you need to connect to a different port number, just change the value. For SSH, this is the port on which the SSH server runs. The port field specifies the TCP/IP port to connect.
