Step 3 – Prepare first run and check file permissions

First of all we need to check permissions on /var/lib/nxserver/home/.ssh/authorized_keys2

Permissions need to be 640, otherwise you won't be able to connect and you'll receive error messages in /var/log/messages.

chmod 640 /var/lib/nxserver/home/.ssh/authorized_keys2

Now we'll need to copy the secure key that was generated onto the client machines so that your NX client can use it. The key on the server is located in "/var/lib/nxserver/home/.ssh/client.id_dsa.key".

If you are using Linux on your client machines you will need to copy it to "/usr/NX/share/client.id_dsa.key" and chmod 644 it.

If you are using Windows on your client machines you will need to copy it to "C:\Program Files\NX client for Windows\share\" on your client machine. I’m using WinSCP to get this done. Just connet to the server as root and and drag and drop the file client.id_dsa.key from right to the left.
