I was hoping to get some help using FreeNX with user authentication disabled. I use keys to authenticate but have thus far been unable to get FreeNX to work.

It works without any problems when I enable user authentication in SSH. However, I can't seem to get it to work via keys. Obviously that is the most secure way. I have also tried copying the FreeNX server pub key into the client and it gave me a corrupted key error message.

If anybody else has managed to authenticate the FreeNX client via ssh keys I would greatly appreciate a walkthrough.

I'm using
Ubuntu 9.10 Karmic x64
With the FreeNX repo.
