The VPN service is intended for access to the CTU network for employees and PhD students. It allows them to use applications accessible from the CTU network from home.
Set up using Network Manager in Linux

The status in other distributions may vary.
Open the Network Manager menu by clicking on its icon, select VPN connection and Set up VPN .
