The text field should now be filled in with the path to your private key. * In the “Category” section, select the “Session” option towards the top of that list of options. Fill in the “Host Name” field with your account hostname (your account domain or IP address will also work). * To save this profile for later so you don’t need to do this each time you connect, type a name for this session in the “Saved Sessions” text field on the lower half of that screen. Then, click on the “Save” button to the right and the session will now be saved for later (it will show up where “Default Settings” is showing). Next time you connect to the server, you would simply select the session you created and then click on the “Load” button, and then select the “Open” button at the bottom to load that saved session. |
