How to use TightVNC?

**Admin** · 11-Jan-2007, 10:58 PM

I need a way to control a remote desktop to help out a friend and I found TightVNC. I had him install the app and run the "server", then I installed the app on my machine and launched the "viewer". When I lauched the viewer it asked me for "vnc server"...which I assume it wants to know which machine I want to connect to. I had my friend mouse-over the VNC icon in his system tray, but it only shows him his LAN IP address of 192.168.0.3. Obviously that isn't what I need to connect to his machine....now what?

Possible Solution

If he has a router which it sounds like he has then you will need to setup a port forward on the router so port 5800 and 5900 are forwarded through to his pC. obviosuly that does leave you a bit open potentially on the internet unless you restrict it to certain IP addresses using a firewall if the router has one. You then connect to the IP his router has - www.microshirt.com is a quick easy way to get that (from his machine of course)

Also

running the VNC server, go to http://www.whatismyip.com this will display his current public IP. This is the IP to which you want to connect. You also need to set up his router to forward the VNC traffic to his computer 192.168.0.3 This is usually done by forwarding ports 5800 and 5900 for tight VNC. For more details on how to do that, click on the link for his router on the following page:
