Quick and dirty way to remotely connect to GDM

This is a quick & dirty way how to remotely connect to another machine on the same network (and start a gnome user session via GDM if needed).

First ssh to the host where you want to be able to connect to and install the x11vnc package:

[user@server ~]$ sudo yum install x11vnc

Run the installed x11vnc server:

[user@server ~]$ sudo x11vnc -display :0 -auth guess

Connect to the the remote desktop from your machine:

[user@machine ~]$ vncviewer 192.168.1.100

This is dirty  because of this:
