    Hello,

    I am developing a system in Windows.
    This system will be installed on client machines.
    Also, bundled with the system, is a VNC server which listen to the
    standard port, 5900 on the client machine.

    What I need is the following: suppose I am the administrator of such
    system copies, and the client needs assistance, and suppose I cannot
    access the client computer because it has a firewall.
    The solution I thought was this: bundle a copy of plink with the
    system, make a TCP SSH connection with a SSH server which has a VNC
    Viewer and do a "reverse" connection, in such a way that from that
    server I can access the client machine, even if it has a firewall.

    The command I wrote for achieving this was:

    plink -ssh -R 49687:localhost:5900 user@server

    in order to connect to the client machine by simply typing in the
    server:

    vncviewer localhost:49687

    But I did the try and the connection was refused. What am i doing
    wrong?

    Thank you very much.

    Juan
