Thank you for the great post… I know it’s quite old, but Google referred me
I followed the directions here, and had nxserver up an running in about 15 minutes (had to be done over ssh, which slowed me down).
Prior attempts at installing nxserver took several hours each, as the directions I was following were nowhere near as clear, so I thank you profusely for such concise and useful information!

I tried this part and i am not sure on the commands on how to do this?
I have some additions to the problem of enabling thes password authentication.
I don’t like password authentication via the internet, even it is encrypted (Brute force attack etc).So I have created workaround. For this I use the inetd.conf and a second configuration file for the sshd.I also created a “new” service:
ssh-nx
/etc/services:
ssh-nx 23/tcp #local fuer nxserver
ssh-nx 23/udp #local fuer nxserver
Then I created two entries in the inetd.conf.
At first the entry for nx-user. This can only use authentication keys.
ssh stream tcp nowait root /usr/sbin/sshd sshd -i -4
The second entry is the entry for the local users on the nxserver machine.
Here you will see, that there is used another configuration file. It is /etc/ssh/sshd_config.nx. In this config file password authentication is allowed.
For more security I also have done the following entry:
AllowUsers: user1@127.0.0.1 user2@127.0.0.1
So there is no possibility to abuse the sshds.
And here is the second entry in the inetd.conf:
ssh-nx stream tcp nowait root /usr/sbin/sshd sshd -i -4 -f /etc/ssh/sshd_config.nx

Very minor issue, but the command to check if the service is running is
sudo /usr/NX/bin/nxserver –-status
(note the second dash)

Thanks, jeremy. There actually are two dashes in the raw text, but either WordPress is dropping one of them before displaying the article, or they are just so small that it looks like only one dash. In any case, I added a note under that line to make it clear that there are two dashes there.

Another way to fix the ssh config is to replace:
AuthorizedKeysFile /usr/NX/home/nx/.ssh/authorized_keys2
with:
AuthorizedKeysFile %h/.ssh/authorized_keys2
Then everything works as it should.

great article. easy to follow, yet very comprehensive. Thanks!

Hello,
in simple words – great job. Hint: WordPress makes a long dash from the two dashes (thanks to autocorrection). Everything worked like charm in Ubuntu 9.10 i386 with actual packets.
Thanks a lot

Any way to install & use the nxserver without root access??
That would make it MANY times more powerful (to the masses, and me!)

Thanks for the well defined ‘How-To’. I too had my server up and running in about 15 minutes after following your instructions.
I kind of agree with the idea of leaving out the ‘Shut Down’ functionality from a terminal services type desktop though.

Thank you so much!
I had been struggling with this for almost a month!!
No doubt NX gives unparalled performance gain!

Dude, thank you so much. Worked like a charm … after hours of installing, reinstalling and hair pulling I (a Linux newbie) was able to get everything to work. SUPER DOOPER AWESOME. Cheers

Thank you for the post.
I have a problem with nxclient. I could connect to the server, but it does not show title bar and status bar for window. If so is the case, how should i launch the program through NX client? HOw should i start the terminal ?
