for previous users of NoMachine- we have upgraded the NoMachine server software on the CADE linux machines and because of backwards-incompatible changes, you will need to DELETE ALL OLD CONNECTIONS in your NoMachine client.
All lab1 and lab2 machines are running NX Server. This allows you to open a desktop connection similar to VNC without the need to start a separate vnc server session. To connect you will need to install the NX client on your local machine. The downloads are available from the NoMachine website. Clients are available for Windows, OS X/macOS, Linux and Solaris.
More, in-depth, instructions can be found in the NoMachine Support page.
What remote machine or what’s the full name to connect to? See this page.
