Connecting to the Lab VPN

If and only if you are off campus, you will need to connect to Clemson’s VPN using OpenConnect. Follow the instructions here if that is the case.

First you must download the OpenVPN config file for your account. The config file is in an email titled “CU Cyber Lab Access” from [email protected]. Check your email and download the file.

In a terminal, navigate to the folder with your personal OpenVPN config file ending in .ovpn and run the following command.

sudo openvpn --config <username>.ovpn

Testing Connection to the Lab

At this point you should be connected to the lab VPN. To test your connectivity execute the following command.

ping -c 4 oracle.lab.cucyber.net

If the ping succeeds then you’ve successfully connected to the VPN and your DNS is working as intended!

If you are having issues, check to see if you are already connected to the VPN or connected more than once. The VPN does not allow concurrent connections and if there are multiple connections, they end up fighting each other by disconnecting the others every five seconds.
