Real VNC ?s

lobo_pac · January 9th, 2004, 06:03 AM

1) from what i understand i need to openup port 5800, do i need to open up a range, or is just 5800 the only one?

2) i have dynamic dsl, but my router keeps my connection fairly static and my ip rarely (if ever) changes as long as the router doesn't restart. would a service that gives me a pseudo static ip be worth it?

3) i mostly will want to access my desktop from my work computer. my computer at home is firewalled as is my work computer. i am unable to change any port settings at work, but can only do so at home. will i be able to access my home computer from work even though my work is behind a firewall that i cannot change? i know i won't be able to access my work computer at all from home.

2) It doesn't hurt you. I have service from dyndns, but I also run web and ftp server.

3) Probably no, unless you manage to change the ports vnc listens to to something the firewall at work lets past. If it inspects the traffic, it will not let it go no matter what. (this is, if the normal vnc ports are blocked)

2) If it rarely changes, why even bother investing in something like this? http://www.dyndns.org/ If it was changing every 12 hours or something then i would suggest getting something. Other than that no.

3) if your works firewall is blocking alot of the ports so you can access VNC at home there really isnt much you can do. You could try to run VNC on port 80 (internet) and see if that works. Of course if your network admin is smart he/she can see what your doing and they might not like that

how do you run it on port 80? i looked, but don't see where to do that.

can i do that at home?

does it jeapordize network security? i work at a medical office that needs to have it's network fairly secure due to patient confidentiality; i wouldn't want to leave wide open holes.

personally if you work blocked the default port for vnc i wouldnt bother trying to get around it. there is a reason why its blocked. talk to your network admin perhaps he/she can help you out with something

What I have that works....
Home:
A dynamic DSL IP
Linksys Router with ports forwarded
Static IP on my home PC (this seemed to be important in my case)

Work:
T1 on a domain
Firewall not in my control

I can use VNC, PCAnywhere and XP's remote desktop to access my home pc from work. I cannot access work from home because of the work firewall.

VNC - port 5900 forwarded
PCAnywhere - ports 5631 and 5632 forwarded
XP remote desktop - port 3389 forwarded

You could try using no-ip.com if you have a dynamic IP address.

I would talk to the network admin.

Believe me, I HATE IT when people at my work try to bypass the firewall, to run things like P2P or messenging software. If you try to bypass the in-place security the admin may just sound a security alarm and you'll be in a huge mess. Ask them FIRST.

no firewall admin in their right mind would open ports like those to permit users to access their home pcs.

1) it serves no business purpose.

2) if this type of usage was permitted, then they would have implemented a vpn solution.

3) it goes contrary to the 'Deny all except...' rule.

forget about using vnc w/that firewall in place.

if you want to access your home pc from work, you will need something like GotomyPC.
