VNCServer help: proxy not blocking the port, but VNC still not coming through


:edit
{solved}... port is not actually a port. proxy only allows http request, and no tcp traffic. I couldn't even ssh until I used corkscrew.

:end edit

Hypothetical situation... Let's say my work has a proxy, and doesn't have port 8085 blocked, so I set up java based VNCserver, but it still doesnt' work (just times out). However, any other application, like http (ie: apache) DOES work on 8085.

I'm guessing the proxy sees a line of code or something coming through and kills it?

Could be many things.

A (free open-source) tool like ethereal is worth its weight in platinum. In cases like these, "guesses" don't mean much.

I think its called wireshark now but same idea. Any kind of port / packet sniffing / loging program will help you a lot to see what port it is really trying to come in on.

Also make sure that port 8085 is pointing/forwarded to your pc and nothing else is using that port number otherwise it won't work.
