HPC/Network Access/PuTTY Configuration/The Carbon login nodes

Configuration for interactive access

1. In the main PuTTY Configuration window, click Session at the top of the tree on the left.
2. Select the Mega session and push Load. This session will be the basis for the next steps.

   

3. Click "+" in front of SSH in the tree.
4. Click SSH itself.
5. Uncheck the checkbox Don't start a shell or command at all.
6. Click Tunnels.
   • Select each existing entry in the "Forwarded ports:" field and push Remove.

     Since we cloned the Mega session, there might be one entry with L33301. No forwarded ports should remain at this point.

   

7. Click X11 in the tree.
   • Click the checkbox Enable X11 forwarding.
   • Set X display location to :0

   

8. Scroll to the top of the tree and click Session. Enter the host details:
   • Host name: localhost
   • Port: 33301 (referring to the tunnel set up above as L33301.)
   • Protocol: SSH (leave at the default).
   • In the Saved Sessions field, enter Clogin
   • Push Save. The entry will appear in the list of saved sessions.

   

To use licensed applications remotely

Begin adding tunnels

1. In the main PuTTY Configuration window, click Session at the top of the tree on the left.
2. Select the Clogin session and push Load.

   

3. Verify that the name "localhost" appeared in the Host Name field above.
4. Click "+" in front of SSH in the tree.
5. Click Tunnels.

Add tunnels for VNL

1. Under Add new forwarded port, enter:
   • Source port: 6200
   • Destination: mgmt03:6200
   • Push Add.

   

2. 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

   

Add tunnels for COMSOL

Follow steps similar to VNL shown above. Use the following port numbers and host names:

Source Port	Destination	Options
1719	mgmt03:1719	Local, Auto
33317	mgmt03:1718	Local, Auto
33318	mgmt04:1718	Local, Auto
33319	sched1:1718	Local, Auto

Because no port number is the same between VNL and COMSOL, their tunnel configurations can coexist.

Finish adding tunnels

1. Scroll to the top of the tree and click Session.
2. Verify that "Clogin" shows in the Saved Sessions field. If it does not, go back to section #Begin adding tunnels.
3. Push Save.
