How to connect to the GPC, from a Mac

Command line only:

Launch the Terminal app and type:

ssh -A

Replace "pennkey" with your GPC username. You will then be prompted for your password, which is your PennKey password.

 

Graphically (using X Windows System):

Install XQuartz.  Open the Terminal app and type:

ssh -XA

Replace "pennkey" with your GPC username. You will then be prompted for your password, which is your PennKey password.

If you're running MacOS Sienna, you will need to edit /etc/ssh/ssh_config and add the line "XAuthLocation /usr/X11/bin/xauth" after the line "Host *".  You can edit this file from an administrator account using the sudo and nano commands:

sudo nano /etc/ssh/ssh_config
