Lj2012: /* Installation */

My goals were simply to be able to connect to a container using an NX client. This is handy for when I work from home and wish to run a web browser on my work's internal network to access local resources. I connect using a gutsy desktop and using nxclient.

= Installation =

Create a new container using the gutsy template. Edit /etc/apt/sources.list and enable the "multiverse" repository.
Install X and XDM
<pre>apt-get install xorg xdm</pre>
Then add this 3rd party repo to sources.list
<pre>
deb http://www.datakeylive.com/ubuntu gutsy main
deb-src http://www.datakeylive.com/ubuntu gutsy main
</pre>
Install the repo keys and update:
<pre>
wget http://www.datakeylive.com/ubuntu/dists/gutsy/wjeremy.key -O - | apt-key add -
wget http://www.datakeylive.com/ubuntu/dists/gutsy/alivesoftware.key -O - | apt-key add -
sudo apt-get update
</pre>
Install FreeNX (*)
<pre>
apt-get install expect openssh-server tcl8.4 libxcomp2 libxcompext2 libxcompshad nxlibs nxagent nxproxy nxclient freenx openssl
</pre>
For Ubuntu 8.04 :
<pre>
apt-get install expect openssh-server tcl8.4 libxcomp3 libxcompext3 libxcompshad nxlibs nxagent nxproxy nxclient freenx-server openssl
</pre>
Finally install XFCE
<pre>
apt-get install xfce4
</pre>

== Configuration ==

=== Configuring X ===
In /etc/X11/xdm/xdm-config, comment out the line where it says '''DisplayManager.requestPort: 0'''

In /etc/X11/xdm/Xservers, comment out the line ''':0 local /usr/bin/X :0 vt7''' (this starts a local X server, which will fail)

In /etc/X11/xdm/Xaccess, uncomment the line with '''* #any host can get a login window''' (Please keep in mind the security implications by the above line. Read the comments found in the file and set it appropriately)

=== Configure NX Server ===

Edit /etc/X11/xorg.conf. Ensure that the files section looks similar to this:

<pre>
Section "Files"

# path to defoma fonts
FontPath "/usr/share/fonts/X11/misc"
FontPath "/usr/share/fonts/X11/100dpi/:unscaled"
FontPath "/usr/share/fonts/X11/75dpi/:unscaled"
FontPath "/usr/share/fonts/X11/Type1"
FontPath "/usr/share/fonts/X11/100dpi"
FontPath "/usr/share/fonts/X11/75dpi"
EndSection
</pre>

Now create a local user account:
<pre>useradd -m <username></pre>

Now add this user to nxserver:
<pre>nxserver --adduser <username></pre>

=== Configure NX client ===

Setup the Host/Port.
In the desktop section select Unix and Custom. In Settings, select "Run the default X client script on server" and select "New virtual Desktop".

Now try to connect. You should get the XFCE desktop.

Thanks to dantalizing for the feedback.

== Troubleshooting ==

(*)
If you get any errors like:
<pre>
dpkg: error processing /var/cache/apt/archives/libxcomp3_3.1.0-6-2_i386.deb (--unpack):
trying to overwrite `/usr/lib/libXcomp.so.3.1.0', which is also in package libxcomp2
</pre>
while installing the libxcomp package, just force-install the libxcomp package:
<pre>
# cd /var/cache/apt/archives
# dpkg --force-all -i libxcomp3_3.1.0-6-2_i386.deb
# apt-get -f install
</pre>
