SSH access to Purdue AF¶

Although the web-based JupyterLab interface is the recommended way to access Purdue AF, it is also possible to connect to your session from a terminal via SSH.

To achieve this:

1. Start an AF session in a normal way

   1. In a web browser, login to Purdue AF and start a session.

2. Obtain an authentication token

   1. Go to File -> Hub Control Panel.
   2. Click Token tab in top left of the page.
   3. Click Request new API token to obtain the token string - you will need it in the next step.

3. Log in to your session from external Terminal

   ssh <username>@jupyterhub-ssh.cms.geddes.rcac.purdue.edu
   

   • If you are using CERN or FNAL account, remember that your username should include -cern or -fnal suffix, respectively.
   • Instead of password, paste the token obtained in the previous step.

4. (Optional) Set up an alias in .bashrc

   By adding the following line to ~/.bashrc or ~/.bash_profile on you local machine, you can avoid copy-pasting the token every time. Note: you will need to have sshpass utility installed on the local machine.

   alias purdue-af='sshpass -p <token> ssh <username>@jupyterhub-ssh.cms.geddes.rcac.purdue.edu'
   

   Now simply running the purdue-af command will immediately connect you to Purdue AF, provided that you had already started the session.
