  2. Navigate to https://vc.cs.illinois.edu/ui in a browser

  3. Log in with your NetID and password

  5. Select the VM from the search results

  6. Select the 'Actions' dropdown menu, navigate to Power --> 'Power On' (or use the shortcut Ctrl + Alt + B)
    • Select 'Reset' if the VM is in an unusable state (or use the shortcut Ctrl + Alt + T)

  7. Give the VM a couple of minutes to boot up, and then connect to the VM
    • Connect to the campus VPN
    • SSH into the VM (i.e. ssh NetID@sp21-cs100-01.cs.illinois.edu)
    • Contact your course staff if you have trouble logging in to your VM

Troubleshooting Login Issues

If you are unable to log in using the connection methods above try these alternatives to access your VM(s)

  1. If you are getting an access denied or permission denied error when using a web browser to access your VM(s) at vc.cs.illinois.edu try using an incognito window and/or clearing your browsers cache to fix your login issue. Browsers often cache data or old credentials that can cause logins not to work correctly so clearing your browser cache can help. Please see the following links for browser specific instuctions:

    Safari:
    clearing cookies: Clear Cookies in Safari
    clearing cache: Clear Browser Data in Safari

    Microsoft Edge: To clear your browser cache and cookies in Microsoft Edge, go to Settings > Privacy > Clear browsing data and select choose what to clear. You are then able to select what you would like to clear from the pop up box that appears. Once you have selected what you would like to remove click clear now at the bottom of the box. You can also type "edge://settings/clearbrowserdata" in your address bar to access this function. 

    Google Chrome: Clear Browser Cache in Chrome

    Firefox: Clear Browser Cache in Firefox

  2. If your VPN connection is set to use the split_tunnel profile try changing it to tunnel_all. There was a recent change in default vpn behaviour that could have changed this option when you connect so make sure you try tunnel_all if connecting over split_tunnel doesn't work. To do this click connect like you normally would on your VPN client. This will launch two windows the window where you put your credentials in to access vpn and another that looks like this:

    tunnel all

    Please change the group field to: 2 tunnel all

    Then put in your credentials and continue connecting like you normally would
