Test your own VNC

It can be a royal pain in the behind to debug VNC running across a firewall/router setup while you're *behind* that firewall (eg on the VNC server itself). With some firewall/routers (like mine, a Belkin High-Speed Mode Wireless G), even if you have the firewall's port-forwarding for VNC setup correctly, you may not be able to connect a viewer to your server, even if you're using the "real world" external IP address that you just (tried to) enable. Trying it will result in the super-cryptic, not very helpful but darned popular error "Connection refused (10061)".

Fortunately, there's an easy solution. Simply go to gotomyvnc.com and it will launch a port scan on your IP to see if your router rules have been setup correctly. Kewl!
