HPC/Network Access/PuTTY Configuration

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.

Configuring

The following steps need to be performed once for each workstation you wish to use to access Carbon.

• The SSH Gateway
• The Carbon login nodes
• Accessing Carbon licenses remotely (advanced)

Connecting

To connect to Carbon for interactive work, or to access its networked licenses, perform a preparatory step, needed only once for a given Windows login session.

• Connecting to the SSH Gateway

From then on, and while the preparatory window remains active, connect as often as desired.

• Connecting to a Carbon login node

File Transfers using PSFTP

1. Configure your PuTTY installation as shown above.
2. Connect to the SSH Gateway, as shown in the preceeding section.
3. Open the psftp application, and select your configured clogin PuTTY saved session name as host to connect to.
