Brilliant idea to use mconnect! Unfortunately it doesn't work for me. A colleague of mine traced down the problem as far as this...

For the record, I can't get the mconnect command to work as an ssh ProxyCommand. I was able to run it under truss, and I can see it forks a child process so that the parent handles the data in one direction and the child handles the data in the other. However, for some reason, it's failing to read the data. The sequence goes like this: 

    Parent - reads 20 byte version string from remote
        - writes 20 bytes to local
    
    Child - reads 31 byte version string from local
        - writes 31 byte version string to far end
        - reads 792 bytes of protocol data from local
    Parent    - reads 744 bytes of protocol data from remote
        - hangs at read(5, 0x000264B4, 8192)
    Child     - hangs    at read(0, 0x000264B4, 8192)

Neither of them writes the supposedly pending protocol data, and both are supposedly attempting to read more data, but not getting it. My guess is that it has something to do with line buffering and both processes are waiting until they get a line terminator which is not forthcoming. (The version number strings are terminated with a new line, but the protocol data block is not).

I really wish I could have gotten it to work, it would have been a simple, easy solution for me.

Thanks again!
