Overview
Carbon hosts floating network licenses for several applications. The applications are intended to be run on the compute nodes for compute jobs, or interactively on login nodes for purposes of pre-run preparations or post-run analysis and visualization. The latter will require the use of remote graphics which can be impracticably slow. It may be possible to run the application natively on your machine, foregoing the need to push graphics data over the network. If the application requires a license and you do not have one yourself, you need to configure the application on your machine to access Carbon's license servers. The concept you will use is called port forwarding, also known as tunneling. It makes a port on your machine act like a port on one of Carbon's hosts.
The configuration settings to forward one or more ports will be stored in a PuTTY session that is normally used to connect to a Carbon login node. There are two alternative routes to reach a login node:
- Use Mega intermediate host - applicable for most users.
- Use VPN to connect directly to a login node – available to Argonne employees only.
The port configurations are largely the same, except for the PuTTY session they will be applied to.
The table on the right lists port numbers for your system and the matching host:port destinations on Carbon.
- Tunnel configurations for several applications can coexist as long as Source Port numbers do not overlap.
- Keep the default options Local, Auto for all forwarded ports.
- Important: Most applications need to be explicitly configured to use a forwarded port.
- Configure such an application to use
localhostas the license server, and the Source Port shown in the table. - Repeat if there is more than one entry.
- Find links to application-specific instructions in the table.
- Configure such an application to use
Begin adding forwarded ports
For connections using Mega
- In the main PuTTY Configuration window, click Session at the top of the tree on the left.
- Select the Clogin session and push Load.
- Verify that "localhost" appeared in the Host Name field above. Go back to step 1 if it does not.
- Click "+" in front of SSH in the tree.
- Click Tunnels.
- If your session has existing forwarded ports and you wish to start over:
- Select each existing entry in the "Forwarded ports:" field and push Remove.
- No forwarded ports should remain at this point.
For connections using VPN
- In the main PuTTY Configuration window, click Session at the top of the tree on the left.
- Select the Clogin session and push Load. We will clone this session to connect directly.
- Alter the Host Name and Port fields to say "clogin.cnm.anl.gov" and 22.
- Enter "Clogin direct" in the Saved Sessions field.
- Push Save.
Proceed at step 4 in the previous section.
Example: Add forwarded ports for VNL
- Under Add new forwarded port, enter:
- Source port: 6200
- Destination: mgmt03:6200
- Push Add.
- Repeat with the following settings:
- Source port: 6201 (not 6200!)
- Destination: mgmt04:6200
- Push Add.
- You should now see these two entries:
- L6200 mgmt03:6200
- L6201 mgmt04:6200
Example: Add forwarded ports for COMSOL
Proceed similar to the VNL example above, but create 4 entries with the following port numbers:
- L33318 mgmt03:1718
- L33418 mgmt04:1718
- L1719 mgmt03:1719
- L1720 mgmt04:1720
You can configure forwarding for both VNL and COMSOL at the same time since all their port numbers differ.
Finish adding forwarded ports
For connections using Mega
- Scroll to the top of the tree and click Session.
- Verify that "Clogin" shows in the Saved Sessions field. Otherwise, retrace your steps from section #Begin adding forwarded ports.
- Push Save.
- To use the forwarded ports, open a new "Clogin" session. You do not need to terminate an existing connection to the mega SSH gateway.
For connections using VPN
- Scroll to the top of the tree and click Session.
- Verify that "Clogin direct" shows in the Saved Sessions field.
- Push Save.
- To use the forwarded ports, push Open.
