NX error

When trying to connect to my server with (No Machine) It spits out an error after connecting.

Can not find RFB Client. Please contact your system administrator.

Any one know a fix for this.

Sounds a bit like you’re telling Nomachine to use “vnc” … !!

If I’m right you’ve gone in and overridden the default (which is “unix”) and replaced it with something which isn’t going to work … (!)

By default , “unix” uses the “ssh” protocol, which you have working.
VNC is something entirely different which is not configured (unless you’ve done this) and isn’t a comparable solution.
