Course VPN
The Course VPN (CVPN) feature enables desktops to directly reach each other.
It replaces "Turn off network isolation". Previously, turning off network isolation let desktops talk to others on the same server, but communication couldn't happen between servers or data centres.
Course VPN lets any desktops in a given course communicate, no matter the server or data centre.
This feature is only available for Ubuntu and Windows 10 operating systems. For other operating systems, you can still use "Turn off network isolation".
The screenshots below show the CVPN interface as seen from the terminal, together with some extra properties of the connected interface.
Terminal IPs:
These screenshots show the VPN network interface that appears when training workstations are created. You'll notice two student workstations with the `edge0` interface—that's the course VPN.
Additional Properties:
