==Connecting to the New Cluster==
==Connecting to Sapelo2==
Access to the new Linux cluster is through secure shell (ssh) to the host IP address 128.192.75.104 (note that connection via telnet is not safe and it is therefore disabled). 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). An SSH Secure Shell Utility is available for Windows on the [https://eits.uga.edu/hardware_and_software/software UGA Sitesoft] page (you will need to enter your UGA myID and password to download the software).

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.
