Connect to the HPCC

Connect to the gateway

Open the SSH client in your local computer and run ssh -XY <username>@hpcc.msu.edu, where <username> should be your HPCC account name. SSH will prompt for your password. Please type the password of your MSU NetID (the password will be invisible). Upon a successful login, you will see a welcome message and current usage load for each development/dev-node.

Our gateway is for entrance to the HPCC system only. Connect further to a dev-node for your program running and other tasks. See the next section.

NOTE: If you have difficulty in X11 forwarding (e.g. receiving an error message "Warning: untrusted X11 forwarding setup failed: xauth key data not generated"), please check your local machine's "config" file ($HOME/.ssh/config) setting. It should look like

1
2
3
4
5
Host *
ForwardAgent yes
ForwardX11 yes
ForwardX11Trusted yes
XAuthLocation /opt/X11/bin/xauth

SSH to a dev-node

To access a dev-node from gateway, pick one and type "ssh -X node-name" (if you don't need to launch a GUI program, omit -X). See here for dev-node usage and policy.

Test X-Windows

If your local computer has a X-Windows client installed (such as Xquatz, or mobaxterm ...) and you log into the nodes with the -X option, you can test if GUI will work by running xeyes on the command line. If everything is set correctly, you should see a pop-up window containing a pair of eyes.
