Remove presently-installed vnc client/server:
<code>
# yum remove vnc
# yum remove vnc-server
</code>
Download and install tightvnc client/server (note it has been replaced by tigervnc as of Fedora 11)
<code>
# yum install tigervnc
# yum install tigervnc-server
# vncserver
</code>
Set up a password when script asks you to do so. \\
run "vncpasswd" as each user who will run the VNC service. \\
edit /etc/sysconfig/vncservers - start with "1" \\
chkconfig vncserver on \\
service vncserver restart \\
ps -ef |grep vnc (then find active ports where service is running)
add appropriate ports to a firewall rule as accepted \\

May need to do iptables -L or service iptables stop to test connections.

Can see what ports are active with this command:

<code>
# netstat -tpln | grep "5902"
</code>

__Using x11vnc__ \\

Install package. \\
Ssh into remote system using a PuTTY window. \\
Start service with x11vnc -display :0 \\
x11vnc -storepasswd (set password one time, accept default location) \\
x11vnc -rfbauth /path/to/password/file \\
Use TightVNC or TigerVNC viewer to connect to remote system.

Notes:\\
Geometry will match host machine; the client machine may be too small.

Sample commands to be made via PuTTY window on remote machine:

<code>
$ x11vnc -display :0 -clip 1366x700+0+0 -rfbauth /path/to/passwd_file
$ x11vnc -display :0 -scale 1366x768 -rfbauth /path/to/passwd_file 
</code>

Then use TightVNC viewer and connect to remote host from the client PC.

Best software for displaying the Root Display (:0) is NoMachine and selecting the "Shadow" Desktop...this is also called Desktop Sharing.  Several tutorials are available on the NoMachine website at [[http://nomachine.org/ar/view.php?ar_id=AR11B00098]]
