Hi all --

I currently have remote access to my machine with SSH and X forwarding. It works wonderfully with key-only auth, no passwords are accepted, and I often run graphical apps via my netbook. Fantastic, but a little slow on dodgy/slow connections elsewhere; I'd like to have some compressed or optimised remote desktop going, low colours & resolution etc.. I'd like NoMachine (NX) but am having some trouble connecting. This are the steps I have taken:

1. Unzip 3x NX packages (client, node, server) on server into /usr to create /usr/NX directory.
2. Unzip client package on client.

Server:
3. Created links /etc/rc.d/rc#.d/ to /etc/init.d/

4. Modify scripts/setup/nxserver by:
- fixing user add/del commands in lines 924, 963, 984, 1032.
- comment out command in line 956 (will do manually later)
- drop "2" from authorized_keys2 in line 2573
5. Run: sudo ./scripts/setup/nxserver --install fedora
- doesn't really matter but it's the closest match
6. Change server name & SSH port in /usr/NX/etc/server.cfg (line 31, 36 & 236)
7. Allow admin logins in line 87 of /usr/NX/etc/server.cfg
8. Drop "2" from authorized_keys2 in line 337 of /usr/NX/etc/server.cfg

9. Modify scripts/setup/nxnode by:
- specify SSH port in line 43
- change to local.sh on line 1305
10. Run sudo ./scripts/setup/nxnode --install fedora
- ignoring warning about CUPS detection, I don't have a printer
11. Change server name & SSH port in /usr/NX/etc/node.cfg (line 32, 342)
12. Drop "2" from authorized_keys2 in line 186 of /usr/NX/etc/node.cfg
13. Run: sudo bin/nxserver --restart (no errors)
14. Enable the nx user account by using: sudo passwd -u nx
15. Run twice: sudo bin/nxserver --usercheck seawolf

seawolf@Felicity:/usr/NX $ sudo bin/nxserver --usercheck seawolf
NX> 900 Verifying public key authentication for NX user: seawolf.
NX> 900 Adding public key for user: seawolf to the authorized keys file.
NX> 716 Public key added to: /home/seawolf/.ssh/authorized_keys.
NX> 900 Verifying public key authentication for NX user: seawolf.
NX> 900 Public key authentication succeeded.
NX> 999 Bye.

seawolf@Felicity:/usr/NX $ sudo bin/nxserver --usercheck seawolf
NX> 900 Verifying public key authentication for NX user: seawolf.
NX> 900 Public key authentication succeeded.
NX> 999 Bye.

Client:
The client fails to connect to the server with the following messages:

NX> 203 NXSSH running with pid: 13991
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: 91.109.8.138 on port: 252
NX> 202 Authenticating user: nx
NX> 208 Using auth method: publickey
NX> 204 Authentication failed.

Server:
16. Switch SSH/PAM authentication for the NX own auth (line 206 & 225 of etc/server.cfg)
17. Add the 'seawolf' user with the same password as my SSH key (for argument's sake):

seawolf@Felicity:/usr/NX $ sudo bin/nxserver --useradd seawolf --administrator
NX> 900 Setting password for user: seawolf.
NX> 102 Password: 
NX> 102 Confirm password: 
NX> 110 Password for user: seawolf added to the NX password DB.
NX> 900 Checking user: seawolf with the NX password DB enabled
NX> 306 Administrator: seawolf added in the NX administrator DB
NX> 900 Adding public key for user: seawolf to the authorized keys file.
NX> 716 Public key is already present in: /home/seawolf/.ssh/authorized_keys.
NX> 900 Verifying public key authentication for NX user: seawolf.
NX> 900 Public key authentication succeeded.
NX> 301 User: seawolf enabled in the NX user DB.
NX> 999 Bye.

Checks on the seawolf user are still successful but connecting results in the same failure.

As the failure is of public key auth on the 'nx' user, I created this user on the client and copied the default DSA key as its ~/.ssh/id_dsa but log-in still fails with the same error.

Any advice or pointers would be most appreciated as I've had trouble getting even x11vnc and TightVNC going! I will put this in the Remote Desktop section of the documentation if/when it's working :)
Many thanks in advance.
