NXserver

[The Devil Is A Squirrel]

Hi everybody

I am actually a bit frustrated...spend hours to get run nxserver but with no real luck...

I followed this guide (but I let the port by 22) and now I get the following message when I try a local connection (localhost):

NX> 203 NXSSH running with pid: 25229
NX> 285 Enabling check on switch command

Can anyone help me?

Any help or hint would be very appreciated.

Ok, I've fought with this off and on for a-while, but I finally found the right combination. First of all, forget freeNX. The NoMachine folks have released a "desktop" edition of their latest product called "NX Desktop Server" that is free for personal use (2 users/connections).

Before proceeding, be sure to *completely* remove any previous versions of any of the FreeNX files or libraries. Undo what you have already done, and remove the FreeNX source URLs from your /etc/apt/sources.list.


-----------------------
Step 1 - Download
-----------------------

Download "NX Desktop Server DEB for Linux" from:
http://www.nomachine.com/select-pack...?os=linux&id=1

Download "NX Node DEB for Linux" from:
http://www.nomachine.com/download-node.php?os=linux

Download "NX Client DEB for Linux" from:
http://www.nomachine.com/download-client-linux.php

-----------------------
Step 2 - Install
-----------------------
Install the DEB files in this order:

nxclient
nxnode
nxserver

I just right-clicked on them and installed them...use apt-get if you prefer.

-----------------------
Step 3 - Configure
-----------------------
Load up your /etc/ssh/sshd_config file into an editor:

sudo nano /etc/ssh/sshd_config

Add the following line & save the file
AuthorizedKeysFile /usr/NX/home/nx/.ssh/authorized_keys2

Restart sshd by typing:
sudo /etc/init.d/ssh restart

Verify nxserver is configured properly by typing:
sudo /usr/NX/bin/nxserver --status

This should return:

NX> 900 Connecting to server ..
NX> 110 NX Server is running.
NX> 999 Bye.

If you get any errors here, then something is wrong with your configuration. If not, then NX Desktop Server should be installed.

Before anyone complains, yes, I'm using the NoMachine server key just because it's easy. If you want to generate your own key, you can. These instructions worked for me on Dapper....YMMV. Let me know if you have trouble.....hopefully my notes were correct.

Good luck!

Hi jkbrowne

Thank you so much for your help! It's quite frustrating with those dozens different guides that not work. I think I am almost there, after the handshake I get the following message


and then the message details...

What did I wrong? Can you help me one more time?



Update

Maybe it's the DMZ from my company...but I tried it actually with another PC outside the LAN and get the following failure

The network was just fine. What's wrong?

evan@evan-ubuntu:~$ /etc/init.d/ssh restart
bash: /etc/init.d/ssh: No such file or directory


Anything?

Works great!!! I had it up and running in 3 minutes. Know I can connect from my Gentoo laptop to my Ubuntu dapper workstation. Thank you very much

[jkbrowne]

gurgle:

Sorry, I forgot to mention that you need the ssh package installed beforehand. Be sure it's installed, and then you should be able to continue with the NX installation instructions.

[jkbrowne]

Squirrel:

You definitely should be testing the connection locally (at home), to eliminate firewalls from the equation.

Are you running it on the default port 22?

I'm not sure what's up exactly, but looking at one of your logs:

Info: Connecting to remote host '217.16.104:5008'.

The ip address is missing the 4th octet....this says to me it's attempting to connect to 217.16.104 (which is an incomplete ip address). Check your configuration & verify the address is correct.

Hi jkbrowne

yeah, that's correct because I had removed the digits in the post (maybe paranoid)...

Actually I remove everything and try it again...

Thanks for your help!!


Update

Finally! It runs local, now I will test the remote part...

Question: Will it work in a DMZ or other firewalled environment? Or is it "just like" VNC?

[thk]

Why do they insist on installing in /usr/NX? Very annoying.

[jkbrowne]

Not sure....but I agree, it shouldn't go to /usr/NX. /opt/NX would be my vote, based on the FHS standard.
