Accessing PCs with remote laptop

Postby rimutaka » 2011-05-29 10:26

Hi,

I was informed by my friend about your website and I would like to know more about Ultra VNC.

I have two PC's at home and a laptop which I bring together with me everyday.

The operating system of my PCs & laptop are Windows 7 Home Premium 64 bit.

My two PCs are not in LAN.

I am wanting to access two PCs from my laptop.

Is it possible with Ultra VNC? if possible, do you have the step by step tutorials?

Thanks in advance

Unfortunately, I don't think we do? Yes, it's possible*.

But the general idea would be:

1. At your home router, forward port 4001 (for example) PC#1.
2. Forward port 4002 (for example) to PC#2.
3. Install UVNC server as a service on both PCs, settting up PC#1 to listen on port 4001 andn PC#2 to listen on port 4002. Set passwords.
4. From your remote laptop, start the UVNC viewer application and point it to yourhomepublicipaddress::port, so for example 200.200.200.200:4001 to access PC1 or 200.200.200.200::4002 to access PC2.

Good luck.

*If when you say "not in LAN" you mean they are behind different routers, then you would use whatever public IP addresses each PC sits behind. (Machines behind the same router ARE in a LAN.) But if neither machine has Internet access, then of course it won't work!

Hi B,

Thanks for your prompt reply.

I try to digest your explanation but it's hard to understand as I am not familiar with computer terminologies. This is the reason why I was asking tutorials.

The "not in LAN" I meantioned previously meant that those PCs are not connected each other but separated (sorry for not using the right term).

Regards,

You could check out PortForward.com for more information about forwarding ports at your router, but honestly I don't trust that site very much.

If both PCs are behind the same router (if they both use the same router, either through wired connections or wireless connections) then they are in fact both on the same LAN. One would have a local IP address like 192.168.1.101 and the other would have an address like 192.168.1.102.

If you can't find a suitable tutorial in the UltraVNC FAQ or the documentation, you could try the documentation for similar VNC projects such as TightVNC, RealVNC, and TigerVNC. Sorry I can't be of more help; part of it depends on your specific router, your operating system, and any firewall or security software you're runnning.

I wonder if you might be better served with the LogMeIn Free product (do NOT use their trial version).

Broadly speaking, UltraVNC includes, for free, most of the features that other VNCs like RealVNC charge for, if not unique features. These include MSLogon (Microsoft NT LANMAN/Active Directory integration), repeater support, custom video driver, multimonitor support, etc. I did a recent post about this but am too lazy at the moment to find it for you.

Further, almost all of UltraVNC is still open source under the GPL, unlike most of the other current VNCs.

One downside is that UVNC is Windows-only.
