Getting Connected¶

SSH¶

SSH provides a secure, remote terminal connection to the login nodes. To connect use the load-balanced name, login.farmshare.stanford.edu which will select of the login nodes based on load and utilization.

FarmShare implements Stanford’s Minimum Security Standards policy which requires two-step authentication to access the cluster.

$ ssh ta5@login.farmshare.stanford.edu
ta5@login.farmshare.stanford.edu's password:

Enter a passcode or select one of the following options:

 1. Duo Push to XXX-XXX-XXXX
 2. Phone call to XXX-XXX-XXXX
 3. SMS passcodes to XXX-XXX-XXXX
