[OBSOLETE] nx server HowTo

ryecoaaron · 29. Januar 2013

NoMachine's nx server (link) is an alternative to X forwarding and very easy to install.

As root:

Code

1 - Download client - wget http://64.34.173.142/download/3.5.0/Linux/nxclient_3.5.0-7_amd64.deb
2 - Download node - wget http://64.34.173.142/download/3.5.0/Linux/nxnode_3.5.0-9_amd64.deb
3 - Download server - wget http://64.34.173.142/download/3.5.0/Linux/FE/nxserver_3.5.0-11_amd64.deb
4 - dpkg -i nxclient_3.5.0-7_amd64.deb
5 - dpkg -i nxnode_3.5.0-9_amd64.deb
6 - dpkg -i nxserver_3.5.0-11_amd64.deb
7 - usermod -a -G ssh nx
8 - apt-get install xterm xauth
9 - /usr/NX/bin/nxserver --start
10 - Create user (aaron) from web interface and make sure to add to users and ssh groups.
11 - mkdir /home/aaron
12 - chown aaron:users /home/aaron
13 - /usr/NX/bin/nxserver --usercheck aaron

If connecting from Windows, just download the Windows client (link) and change the desktop to Unix and custom. This will run xterm when you login and you can run any app (gui or otherwise, may have to install libraries like gtk, qt, etc). This works very well for iceweasel (firefox), rdesktop, and vncviewer while using ssh for the connection.

Hi!

Downloaded and installed the nx server on my OMV, but cannot get it to work.

What I did:

Code

wget http://web04.nomachine.com/download/4.0/Linux/nomachine_4.0.362_1_amd64.deb
sudo dpkg -i nomachine_4.0.362_1_amd64.deb
sudo apt-get install xterm xauth
sudo usermod -a -G ssh nx
sudo /usr/NX/bin/nxserver --usercheck brodersen
sudo service nxserver restart

Everything looks good so far, no errormessages or anything.

Then when I try to connect from my Ubuntu machine, I get: "The server was unable to make the local display available or access to the local display is disabled." after it initially logs in via SSH.
I also looks like I am not the only one getting this: https://www.nomachine.com/foru…w-to-enable-local-display

Any ideas?

I'm still using version 3. Looks like the problem only happens with version 4. I will try version 4 tomorrow.

Using ssh with -CY gave the following error on my machine:
"X11 forwarding request failed on channel 0"

Added "AddressFamily inet" and "X11UseLocalhost no" to the "/etc/ssh/sshd_config" file and restarted ssh (sudo /etc/init.d/ssh restart).

Now regular X11 forwarding works, but still not nx.

I forgot to test this out. I don't like how they got rid of the 3.5 free version and there is no equivalent version 4. Starting with version 4, it is closed source and the server uses a different port as well. So, my instructions for 3.5 are completely obsolete for version 4. I will be looking elsewhere now (x2go looks promising).

Do you know what they have in Wheezy as far as vnc? I have not looked yet.

ryecoaaron · 13. November 2013

Haven't looked at Wheezy.

Hopefully tigervncserver is working as it should now. I was using a version that someone modded for Squeeze.

Can't tell and can't test. My root is my only machine running wheezy atm...
