IT/Software/Applications/Remote Login/Nomachine
This is an amazing open source project.
You can use it with little to no restrictions.
Using SSH tunnel with NX connection
Setup the connection to use NX and a non-standard port.
localhost Port 4010
Connect via ssh
ssh -L 4010:localhost:4000 walt@disco
This will open a ssh tunnel on port 4010 and send that to the 4000 port on the remote machine
Now start the NoMachine connection.
Stopping it
right click and close the noMachine application does not often work.
From a terminal you can:
sudo /etc/NX/nxserver --shutdown
It can steal audio from Zoom or other applications if you don't close it.
