Re: Part II: Open NX on Mint 14: Error: Unexpected termination of nxssh

I forgot one thing. The DEFAULTS of Nomachine client are indeed
incompatible with Nomachine server version-3. You have to switch
from NX protocol (port 4000) to ssh protocol (port 22) and then go to
"Advanced" and switch there from system login to Nomachine login.
