ATTENTION!
DO NOT install FreeNX ANY version!!
Instead of that, download packets from http://www.nomachine.com and install them.
Make sure that you are doing CLEAN installation.

To activate the NX user and password DBs, you will have to edit the
NX server configuration file by hand or use the NX Server Manager
web tool available for download on the NoMachine Web site at:
http://www.nomachine.com/download-manager.php
root@knoppix-lnx:/usr/NX/home/nx/.ssh# ssh-keygen -t dsa -f nx_dsa -C "nx@knoppix-lnx"
Generating public/private dsa key pair.
Enter passphrase (empty for no passphrase): <empty for nx user>
Enter same passphrase again:
Your identification has been saved in nx_dsa.
Your public key has been saved in nx_dsa.pub.
The key fingerprint is:
78:fd:99:94:f5:15:47:4c:50:e6:15:18:86:5f:95:dc nx@knoppix-lnx
So,
* nx_dsa = PRIVATE KEY (for clients)
* nx_dsa.pub = PUBLIC KEY
cat nx_dsa.pub >> /home/jormah/.ssh/authorized_keys
Modified my /etc/ssh/sshd_config on the server to use
AllowUsers nx jormah
AuthorizedKeysFile %h/.ssh/authorized_keys # Important: use %h/...
X11Forwarding yes
PubkeyAuthentication yes
PermitEmptyPasswords yes
PasswordAuthentication yes
UsePAM no
passwd -u nx # Unlock account
passwd -d nx # delete passwd
/etc/init.d/ssh restart
/usr/NX/bin/nxserver --restart
TEST:
ssh -i nx_dsa nx@knoppix-lnx

Exit

Connection to knoppix-lnx closed.
So far, everything is ok!
== Client side ==
Download and install nxclient-2.1.0-16.exe (I use Windows XP version)
start NX Connection Wizard
apply configuration settings (name, host, post, type of connection)
enable SSH encryption of all traffix
show the advanced configuration dialog
press "Key" button
import DSA PRIVATE KEY == "nx_dsa" file created ssh-keygen in server side
save settings and login with your server user name and password
Good luck!
