I had freenx working without issue for over a year, then I decide to try and "upgrade" to the newly free NX Server 2.0. I followed recommendations to uninstall the old versions, then I installed the nx client, node and server RPM packages. Now I get the following error on the client:

NX> 203 NXSSH running with pid: 7636
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options
NX> 200 Connected to address: [my ip address] on port: 22
NX> 202 Authenticating user: nx
NX> 208 Using auth method: publickey
NX> 204 Authentication failed.

Any ideas?

Am I the only one with this problem? Sorry for adding another post.

This is the solution, quite a technical:

I'm having exactly the same problem, have you found any solutions to it
