I usually access remote machines over ssh via the commandline, but now need to connect to one using VNC so I can actually use the desktop. Other people can successfully connect to this PC (running Win 2000 or XP, I think) using Chicken of the VNC on their Macs, but I'm not having any luck setting up a connection on my own PC (dual booting Ubuntu 10.04 & Win 7). I've tried tsclient & vinagre on Linux and tightVNCviewer on Windows, and can't get a connection - just black screens/errors/"can't connect" messages.
My question is, what do I need to ask for from the people who can connect in order to set up my own connection? I have the IP, port (display number?), and password for the remote PC - is there some other settings information I need? Or any other advice on this?
Edit: Obviously, I don't know much about VNC, and my knowledge of ssh/other network "stuff" is pretty thin. But from my perspective, it's like this remote computer (that I know is running) doesn't even exist: I can't reach the IP address via telnet, ssh, vnc, anything.
Edit 2: Figured it out - borrowed a Mac. >_<
(Still don't know why it's still obstinately not working on my win/linux box, but I don't have time to chase down institutional firewall issues etc right now ...)
