On the third wizard page, you can choose your protocol type (the NX client

over SSH, you’ll need to open ports 1000, 5000, and 7000 for the first ses-

ports for each session started.

Finally, on the fourth wizard page, you can choose to create a desktop short-

cut for this session and edit the advanced configuration. Once the wizard is

finished, you should have a connection dialog with the Login and Session

details filled in.

Now type in the password you set on the NX server and click Login. Once

this connects and authenticates you should have a complete remote desktop

in a window on your client machine.
