Freenx with the NX client is much nicer, though. Don't give up on it.
The trick is that the commercial NX server always uses the same key that
matches the one built into the client, where freenx generates unique key
pairs for each install. Just use putty to ssh to the server as root
and cat /etc/nxserver/client.id_dsa.key, and in another window open the
NX config screen and push the 'key' button. Then delete the existing
key contents and paste in the correct one including the ---BEGIN and
---END lines. If you have trouble with this, use winscp or other means
to transfer the file over and use the 'import' button. When you get it
right you won't have the authentication failure error. If you have
firewalling involved you may also want to make sure the
"advanced/disable encryption of all traffic" box is unchecked so the
connection will run over port 22.
