    Hi,

    I am developing an application that talks to a server over SSH2.
    Namely, it will execute some commands on the server. So far
    what I do is open an SSH session, open an "exec" channel, do
    whatever I need, then close the session.

    This works perfectly. However, I need to do several things
    in succession; therefore I would like to open a session once,
    and reuse it by opening and closing an exec channel for each
    command. (Thus saving on re-authenticating every time). So
    I open the channel with "sender" like 0, 1 and so on; the
    server gives me back "recipient" ids again like 0, 1 and so
    on. However, when I am done with the command and send a
    MSG_CHANNEL_CLOSE, the server replies with MSG_DISCONNECT
    with reason code PROTOCOL_ERROR and description: Invalid
    channel number? What am I missing?
