SSH

ssh is an executable program that runs on your local computer and allows you to connect securely to a remote computer. We're going to use ssh to access the Lonestar5 compute cluster at TACC, where the remote host name is ls5.tacc.utexas.edu.

On Macs , Linux and Windows (Git-bash or Cygwin)or Linux, you run ssh from a Terminal window. To invoke a Linux Terminal window if you have the Windows subsystem for Linux installed, double-click on the icon for the Linux distribution you installed (e.g. Ubuntu).

In your local Terminal window:

ssh your<your_TACC_userID@ls5userID>@ls5.tacc.utexas.edu

• Answer yes to the SSH security question prompt
• Enter the password associated with your TACC account
• Wait for your 2-factor authentication code to arrive via SMS or app, then type it in
