VNC viewer listen mode - using a connection bi-directional

[Mircea Nanu]

hi!

I have my computer (A) accesible directly from the internet.

my friend has a computer (B) in he's LAN, but he can't configure the
LAN firewall locatet on computer (C) -- C is also a router and all the
stuff :)

i configured my free vnc server v4.1.2
to listen to port 80, so my friend from computer B can see my desktop (A).

is there a way for me to see he's desktop, once he is connected to me?

i thought that if he connects using the viewer in -listen mode, i'll
be able to use the conenction that he initiates to see he's desktop.
so far, no success :(

i guess in other words what i need is a way to use a once established
"remote desktop" connection both ways.. if vnc is not the right
program, is there other program that can help me?

anyone can share a thought?

thanks,
mircea.

The viewer in listening mode is what you are looking for. Give us more
details on what you tried and what the result was.

Since computer (B) is only connected to the internet through computer (C), computer (B)
does not have an IP address assigned to it. When connected from computer (B) to (A), the
connection goes through computer (C) to get to computer (A). So, if you want to get from
(A) back to (B), you still have to go through (C).

see http://en.wikipedia.org/wiki/Port_forwarding for more info on this concept.

neither me or my friend can set up port forwarding on computer C.
why do i have to create a connection
from a client on A to a server on B (trough C with port forwarding)
when we already have a connection from client B (run in -listen mode)
to server A (trough C with absolutly no port forwarding) ??
thanks anyway,
mircea.

I would suggest setting up port forwarding on computer (C) so that you
connect to port "x"
on computer (C) over the internet, and over the LAN, computer (C) forwards
all connections
on port "x" to port "y" on computer (B).
Hope this helps.

Please reply to the VNC list.

basicaly, after he connected from B with his viewer in -liten mode to my
server A, what should i do to see he's desktop? i looked at available
options in tray (vnc icon), and none sugested anything regarding: me
controlling the client desktop.
mircea.

If you want to control machine B, then machine A should be running the
viewer in listen mode. Then machine B starts the VNC server and uses the
tray icon to "Add New Client", putting in the address and port for machine
A.
