Configuring VNC to auto-start – RHEL 6.2

In a previous post (http://blog.edgoad.com/2009/06/configuring-vnc-to-auto-start.html), I covered the steps to configure RHEL 4.4 to automatically start VNC. This allowed users to connect remotely to 1 or more remote desktops. I had a request to repeat the process, however this time for RHEL 6.2. Here are the high-level steps I used to perform this.

1. Install 6.2 desktop mode
2. Install Vmware tools
3. Install tigervnc
4. Set vnc password
• As root, execute vncpasswd
• When prompted, enter the password
5. Edit /etc/sysconfig/vncservers, add root to session 0
   • Add/modify the VNCServers line
   • VNCSERVERS=”0:root”
6. Set vnc to autostart
   • chkconfig –level 5 vncserver on
7. Enable vnc through the firewall
   • Edit /etc/sysconfig/iptables, add the following lines
   • -A INPUT -m state –state NEW -m tcp -p tcp –dport 5800  -j ACCEPT
   • -A INPUT -m state –state NEW -m tcp -p tcp –dport 5900  -j ACCEPT
   • -A INPUT -m state –state NEW -m tcp -p tcp –dport 6000  -j ACCEPT
8. Restart and connect using VNC
