VNC on a network

post #1 of 10
Thread Starter 
Hi

I have been using VNC for some time now, and its normaly on a home network where the VNC is installed on one PC and i connected via VNC client using the IP then user name and password.

Now i have a new task, i need to install VNC on more than one PC which is conected to one IP, so my question is, if i connect to the IP using the VNC client, how will the client know which PC i wish to remote access to?

Thanx

I'd say you could change which port the different computers listen to? Or maybe the second IP listed (at least in RealVNC) is the outside IP somehow unique for that computer (because on my current machine it's NOT my external IP...)

Be careful to read up on this, because you may set yourself up for getting hacked. Last time a Real VNC exploit came out I actually saw someone open up a command prompt on my Dad's computer and try to download a trojan. It was sheer luck I was sitting there...

Well no there is no unique IP when connecting externaly.
There is a unique IP internaly such as 192.168.0.2/3/4/5
IF i want to connect to the PC at my home in london while i am in india i have to connect to my external IP there.
But VNC is only installed on one PC there, so when the VNC client looks for that server there is only one PC reciving the data.



Now i wish to connected to all the PC's in my factory while i am at the hotel in india or at home in london. so i need to connected to the IP address at my factory. But if 4 or 5 PC has VNC how will i tell the client i want to connect to a patricualr PC

You will have to forward a port from each of the lan pc's on your network through your firewall to your actuall public ip. So for pc 192.168.0.2 you would open port 5901. Then to connect to it from the outside you would connect with 89.445.122.2:5901. Then for the next pc you would open port 5902 on the pc with the ip 192.168.0.3, then again to access it from the outside you would connect with 89.445.122.2:5902 etc. Make sure you use vnc with an ssh tunnel though to limit security issues. These ports will have to be opened on your router firewall and possibly on the host pcs as well.

That won't work, you can't forward traffic to multiple pc's on the lan through 1 external ip address. The only way opening the same port on each pc would work is if each computer had its own public ip, or if he was accessing it internally on his lan. Since they are private ip's behind a router a different port on each pc has to be opened so the router knows which pc to forward the vnc connection too.

if you're opening your VNC to the outside world, you may want to check out UltraVNC as it has encryption plugins... it also support windows logins... that way someone can't connect unless they have your encryption plugin, key file, login and password...

Good point, if he's using windows though, he should just setup remote desktop and use ssh as opposed to vnc. If he is using linux machines then he definitely should use an ssh tunnel to connect to the machines.
