Connecting to Sapelo2

Access to Sapelo2 requires an active MyID and password, and two-factor authentication with Archpass Duo. For more details of Archpass Duo, please refer to archpass_duo .

Access to the Sapelo2 is through secure shell (ssh) to the host sapelo2.gacrc.uga.edu . If you have a local system that runs an X Window client or server, you can run X applications remotely.

To connect via ssh, you must have an ssh software and a connection to the UGA campus network. An ssh software is included in recent releases of Unix based operating systems (including Linux and Mac OS X).

If you are using a Windows computer, please download and install PuTTY. You can find detailed instructions on how to download and install PuTTY on your Windows computer at How to Install and Configure PuTTY.

You may also opt to use Cygwin, for which instructions can be found here.
