Hello,

This is third day i am trying to install VNC on Centos 6, on my Dedicated linux server.
I have followed steps from below posts, and something is still wrong.

http://freevps.us/thread-3575.html

I can't connect with desktop environment to my server [VNC Viewer], i only see blank dark background:

http://imageupload.org/getfile.php?i...tled-2.jpg&i=1

When i enter in SHH command "service vncserver start" i get: "Starting VNC server: 2:root A VNC server is already running as :2 [FAILED]"

Is there someone who can help me with that, Team Viewer or so?

Thank you

Ok, do with my tutorial here:

Step 1: If you are running CentOS 6, the command is
$ yum groupinstall Desktop
If you are running CentOS 5,
$ yum groupinstall "GNOME Desktop Environment"
If you are a minimalist, or simply testing, however, it is sufficient to have yum install a simple XTERM client:
$ yum install xterm
Step 2: If you are running CentOS 6, install vnc-server is:
$ yum install vnc-server
Step 3: Create your VNC users
$ adduser yourusername
$ passwd: yourusername
Switch user into the account for each user, and run: vncpasswd This will create a .vnc directory.
$ su – yourusername
$ vncpasswd
Step 4: Edit the server configuration
$ vi /etc/sysconfig/vncservers
VNCSERVERS="1:yourusername"
VNCSERVERARGS[1]="-geometry 800x600"
Step 5: We will create the xstartup scripts by starting and stopping the vncserver as root.
# /sbin/service vncserver start
Step 6: Remote login with vncviewer
Go to your client machine with vncserver and test the VNC.
$ vncviewer -via yourusername@192.168.10.10 localhost:1

thanhlangso, may you help me with Team Viewer ?
Now i get other error:

Code: 
root@bravo612 [~]# /sbin/service vncserver start
: command not foundervers: line 11:
: command not foundervers: line 13:
: command not foundervers: line 17:
: command not foundervers: line 20:
: command not foundervers: line 21:
: command not foundervers: line 22:
 does not existigordr3:igordr3

How i can uninstall following:
Code: 
yum groupinstall Desktop 
 yum install vnc-server

And do the clean install of it ?

I am running CentOS 6.


masterbator - Didn't work. :(
 
no need to reinstall the vnc if it's already installed

kill the VNC first
Code: 
pkill -9 vnc
then clean the temporary dir
Code: 
rm -rf /tmp/.X1*
or if got more than 1 desktop instances started (replace the number 2 with the number of the desktop)
Code: 
rm -rf /tmp/.X2*

then start the vnc again
Code: 
vncserver

it will display message like this:
Code: 
New 'yourserver:1 (root)' desktop is yourserver:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/fprx:1.log

then open up your vnc client and connect to the server this way
Code: 
youripaddress:1

Click to expand...

Ok, contact with me, I will try help you.
 
masterbator, i have followed your steps and managed to run VNC Viewer but just as root user, it says:

You are currently trying to run as the root super user. The super user is a specialized account that is not designed to run a normal user session. Various programs will not function properly, and actions performed under this account can cause unrecoverable damage to the operating system.

When i enter in client this

Code: 
[B]$ vncviewer -via yourusername@192.168.10.10[/B][B] localhost:1[/B]
It says command not found.

I have changed yourusername with mine, created and changed IP...

Also, i have problems following this step:

Code: 
$ vi /etc/sysconfig/vncservers
 VNCSERVERS="1:yourusername" 
VNCSERVERARGS[1]="-geometry 800x600"
I can't after editing close this file by typing ':wq'. It says

Code: 
E45: 'readonly' option is set (add ! to override)
But that is just for user i have created, for root it's fine, i can edit...


thanhlangso, may we use some instant messenger?
MSN, Gmail chat or so?
Write me here adress please.

Checkout screenshot of my desktop:

I can't use internet on it, i would like to have installed Mozilla firefox, after setting VNC server working fine. Also, display colors are wired.
