Introduction

The Carbon cluster is reachable from networks outside Argonne only through SSH tunneling or VPN. Either way has advantages and disadvantages. This page explains how to connect through an ssh tunnel.

Tunneling is a two-step process:

  1. Establish the tunnel.
  2. Connect through the tunnel.

Overview slides (pdf) and specifics for Carbon are detailed elsewhere. Here is a brief summary of the settings to be used for PuTTY.

Note that the PuTTY Configuration panel is somewhat idiosyncratic to operate, notably regarding the concept of Sessions. Numerous screenshots on Google provide general guidance.

Note: To reach the "Session" panel, you have to scroll the tree on the left all the way up and click on the topmost entry.
