How to use VNC server on CentOS
Assume you have CentOS installed with Gnome. If you want to remotely access the GUI to that machine, you can use vnc-server and a vnc client (like Chicken of the VNC). Here's how:
ssh to the machine. If it is behind a firewall, you might have to set up a tunnel.
Make sure vnc-server is installed:
% sudo yum install vnc-server
This is just to initially create configs and choose a password. Now Edit the file ~/.vnc/xstartup so it runs a gnome session instead of crappy twm:
#!/bin/sh # Uncomment the following two lines for normal desktop: # unset SESSION_MANAGER # exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & exec gnome-session &
Kill off your vnc server and restart it:
% killall Xvnc % vnc-server
Connect to your vnc server with host and display number reported with your favorite client. Yay.
