Step 1

• Login as root.
• Uninistall vino if it is already installed by executing :

$ su –
Password:
# yum erase vino
Loaded plugins: dellsysidplugin, dellsysidplugin2, refresh-packagekit
Setting up Remove Process
Resolving Dependencies
–> Running transaction check
—> Package vino.i586 0:2.26.2-1.fc11 set to be erased
–> Finished Dependency Resolution
Removed:
vino.i586 0:2.26.2-1.fc11

Complete!

Step 2

• Download and install the three tigerVNC modules and you need to be able to create the file /etc/X11/xorg.conf  (if it does not already exist) by executing:

# yum install system-config-display tigervnc tigervnc-server tigervnc-server-module
Loaded plugins: dellsysidplugin, dellsysidplugin2, refresh-packagekit
Setting up Install Process
Package system-config-display-1.1.3-2.fc11.noarch already installed and latest version
Package tigervnc-0.0.91-0.12.fc11.i586 already installed and latest version
Resolving Dependencies
–> Running transaction check
—> Package tigervnc-server.i586 0:0.0.91-0.12.fc11 set to be updated
—> Package tigervnc-server-module.i586 0:0.0.91-0.12.fc11 set to be updated

Installed:
tigervnc-server.i586 0:0.0.91-0.12.fc11 tigervnc-server-module.i586 0:0.0.91-0.12.fc11

Complete!

• If the file /etc/X11/xorg.conf does not already exist create one executing:

# system-config-display –noui

• We need to edit it so execute the command:

# gedit /etc/X11/xorg.conf

• Add this section:

• Add these lines to the “Screen” section

Section “Screen”
.
.
.
Option “SecurityTypes” “VncAuth”
Option “UserPasswdVerifier” “VncAuth”
Option “PasswordFile” “/root/.vnc/passwd”
EndSection

The commands below must be done as root

[root@server]# vncpasswd

Password: (Enter your chosen password for VNC here – 8 characters max)

To  Verify use :

[root@server]# vncserver

xauth: (stdin):1: bad display name “linux.server.local:1″ in “add” command

New ‘linux.server.local:1 (server)’ desktop is linux.server.local:1

Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/linux.server.local:1.log

Note on a typical notebook installation THE WIFI CONNECTION DOES NOT COME UP UNTIL A USER HAS LOGGED IN, if you remotely reboot a Wifi connected notebook you will lose all control of it until someone logs in.

# shutdown -r now
You have new mail in /var/spool/mail/root
[root@linux~]#

The system is going down for reboot NOW!
Connection to 192.168.10.10 closed by remote host.
Connection to 192.168.10.10 closed.

After re-booting you should be able to connect with the TigerVnc viewer to the machine and log in.

For the example below to work it would be necessary to disable any firewall or (infinitely more preferable) open port 5900. This  can be found in Gnome at System | Administration | Firewall. If it is not there it can be installed by executing :

# yum install system-config-firewall
[root@server ~]$ vncviewer 192.168.10.10

There is an ssh command that you can use to establish an encrypted tunnel but with tigerVNC there is a simplified command that is much easier to remember

By executing the commands you will do the  same thing.
