I want a simple head setup for my Virtualbox setup, first I used Ubuntu 11.04 which now is beginning to get old, so I wanted to update the OS. I tried Ubuntu server 12.10, which is in my mind perfect, but I lack skills/mind to handle a GUI less OS. It is much easier to change the VRDP port in the gui then all the time go on the internet on my mobile phone to find a solution, I tried to install PhpVirtualbox but realised that it does not support the latest Vbox version, I ended up with an blank page with no login option and 30 maybe answers how I could solve that one
.

- A headless server shouldn't need an X Server: its more software to configure and maintain and running it uses up resources best used for other processes (I'll forego talking about risks right now).
- Virtualbox can run without X Server: see VBoxHeadless.
|
This is my preferred choice, but I lack the skills to add all the NFS and samba information for 6 hard drives and 10 Partitions in an easy way then the manual way ( see "missing Copy and paste in Ubuntu server"). All the settings I need to set in Vbox feels like an jungle from the terminal, I cannot get an overview of what I am doing.

- Just like VMWare Virtualbox has a choice of remote interfaces like RemoteBox, VBoxRemote, PhpVirtualbox, etc, etc if you need more than SSH access + vboxmanage offers.
|
I tried PhpVirtualbox but in avail. Vbox 4.2 was not supported
. Maybe some of the other may work.

- If you succumb to running an X Server + VNC anyway then the best practice is to use SSH to setup a tunnel and access VNC through it.
|
I always go through SSH to access my server (when everything is working accordingly), I have tested with and without SSH.

- If you get error messages then always check if services / processes are running ('ps -C processname' or 'pgrep processname'), if services / processes are listening to the network ('lsof -Pwlnp pidofprocessname -a -i' or 'netstat -anple|grep processname') and always check their log files and system log files for clues.

This were I lack most experience. I cannot find any information what the process who is handling "Desktop sharing" in Ubuntu neither find any log that can tell me what the program does.
With X11vnc in Lubuntu 12.10 installed I can read some messages when trying to start the VNC server, unfortunately the X11vnc log does not give any good information (It is empty), but keep in mind it did work when I set up the server when it was standing in my living room and refuse to work when I moved it back to the guest room (same router same port).

11/03/2013 20:03:19 ***************************************
11/03/2013 20:03:19 *** XOpenDisplay failed (:0)
*** x11vnc was unable to open the X DISPLAY: ":0", it cannot continue.
*** There may be "Xlib:" error messages above with details about the failure.
Some tips and guidelines:
** An X server (the one you wish to view) must be running before x11vnc is
started: x11vnc does not start the X server. (however, see the -create
option if that is what you really want).
** You must use -display <disp>, -OR- set and export your $DISPLAY
environment variable to refer to the display of the desired X server.
- Usually the display is simply ":0" (in fact x11vnc uses this if you forget
to specify it), but in some multi-user situations it could be ":1", ":2",
or even ":137". Ask your administrator or a guru if you are having
difficulty determining what your X DISPLAY is.
** Next, you need to have sufficient permissions (Xauthority)
to connect to the X DISPLAY. Here are some Tips:
- Often, you just need to run x11vnc as the user logged into the X session.
So make sure to be that user when you type x11vnc.
- Being root is usually not enough because the incorrect MIT-MAGIC-COOKIE
file may be accessed. The cookie file contains the secret key that
allows x11vnc to connect to the desired X DISPLAY.
- You can explicitly indicate which MIT-MAGIC-COOKIE file should be used
by the -auth option, e.g.:
x11vnc -auth /home/someuser/.Xauthority -display :0
x11vnc -auth /tmp/.gdmzndVlR -display :0
you must have read permission for the auth file.
See also '-auth guess' and '-findauth' discussed below.
** If NO ONE is logged into an X session yet, but there is a greeter login
program like "gdm", "kdm", "xdm", or "dtlogin" running, you will need
to find and use the raw display manager MIT-MAGIC-COOKIE file.
Some examples for various display managers:
gdm: -auth /var/gdm/:0.Xauth
-auth /var/lib/gdm/:0.Xauth
kdm: -auth /var/lib/kdm/A:0-crWk72
-auth /var/run/xauth/A:0-crWk72
xdm: -auth /var/lib/xdm/authdir/authfiles/A:0-XQvaJk
dtlogin: -auth /var/dt/A:0-UgaaXa
Sometimes the command "ps wwwwaux | grep auth" can reveal the file location.
Starting with x11vnc 0.9.9 you can have it try to guess by using:
-auth guess
(see also the x11vnc -findauth option.)
Only root will have read permission for the file, and so x11vnc must be run
as root (or copy it). The random characters in the filenames will of course
change and the directory the cookie file resides in is system dependent.

And this is the output of running processes, but I cant find any indication of a VNC server
Code:
warning: bad ps syntax, perhaps a bogus '-'?
