Early on in this process, Benson referred me to this post. Now some it it makes sense.

However, what doesn't is the reference to "Change the line in /usr/bin/x11vnc:" in step 1. I attempted to follow these directions, buy was stymied early on by not being able to find x11vnc through xterm. I've dowloaded it, installed it, and run it. I know it's on the nokia. But it isn't in /usr/bin (assuming that this is the /usr/bin in the root directory).

I'd like to figure out a few more things:
1) What is the purpose of the above mentioned step 1? Is it truly necessary?
Adjusts the settings with which x11vnc is started; equivalent to the changes you can make through the tightVNC GUI. The specific change is to allow connections from the local machine; this lets a connection coming out of a ssh tunnel work. (This is normally disabled, because an actual local client connection tends to cause trouble, not only do you get window-in-window-in-window-in... effect, but also the mouse gets stuck.)Wrong, see jldiaz's post below.
2) Does it matter that I was able to establish the ssh connection without following this step?
Well, the ssh connection is independent of this; these changes only affect VNC.
3) Why can't I find x11vnc? Is there a way to preform an automated search for something in xterm?
It should be there if you've installed x11vnc on your N800; I'm a little confused here, though. Initially, I thought you were trying to use a VNC server on your desktop so you could control it from a client on your N800. Now it seems you're trying to control the N800 from a client on the PC? (That's what the instructions were for, but I assumed you would turn them around for the reverse connection, since I thought that's what you wanted...)

Oh, and if you can run a program (as indicated below), which will tell you where it is:
Code:
which x11vnc
4) Am I correct in assuming that x11vnc is the vnc server app for my nokia? I've already managed to connect to the nokia vnc server via my XP VNC client (on my home WLAN). I did so by setting up an SSH between the two, running x11vnc in xterm and using the tightVNC viewer on my XP box.
Yes, that's correct. Assuming you told tightVNC to connect to 127.0.0.1:1 (or some such), you're going through the SSH tunnel (which you shouldn't be able to, without tweaking the x11vnc script)Wrong, see jldiaz's post below. If, OTOH, you used your actual N800 IP or hostname, then it wasn't going through SSH, and should work.

For remotely connecting from your N800 (out on the internet somewhere) to your PC (on a LAN behind a NAT with a port forward for SSH), you'll need to connect via the NAT's WAN-side IP.
