Once the VPN is downloaded you will need to open up the Cisco AnyConnect client. Type in vpn.clarkson.edu for the VPN name and then click "connect" then you will need to enter in your Clarkson username and password.
On Ubuntu 16+
Download the vpnc client (probably avaliable via aptitude/apt-get) instead of using the AnyConnect client.
Follow these instructions below and let me know if it does or do not work.
