    Has anyone got port forwarding to work with an oracle database?

    I have OpenSSH 3.9p1 on my database server (Oracle 8i running Solaris
    2.6) and my client is a PowerBook (running OSX 10.3.5) with OpenSSH
    3.6p1 (I wish apple would update this) and when I try to set up the port
    forward the connection (using java thin client drivers) through it times
    out. Running the following from the client :

    ssh -v -L 2521:dbserver:1521 user@dbserver

    connects successfully and starts up a shell and then when I connect
    using the java thin client () I get :

    debug1: Connection to port 2521 forwarding to dbserver port 1521 requested.
    debug1: channel 3: new [direct-tcpip]
    debug1: channel 3: open confirm rwindow 131072 rmax 32768
    debug1: channel 3: read<=0 rfd 9 len 0
    debug1: channel 3: read failed
    debug1: channel 3: close_read
    debug1: channel 3: input open -> drain
    debug1: channel 3: rcvd eof
    debug1: channel 3: output open -> drain
    debug1: channel 3: obuf empty
    debug1: channel 3: close_write
    debug1: channel 3: output drain -> closed
    debug1: channel 3: ibuf empty
    debug1: channel 3: send eof
    debug1: channel 3: input drain -> closed
    debug1: channel 3: send close
    debug1: channel 3: rcvd close
    debug1: channel 3: is dead
    debug1: channel 3: garbage collecting
    debug1: channel_free: channel 3: direct-tcpip: listening port 2521 for
    dbserver port 1521, connect from 127.0.0.1 port 49818, nchannels 4

    All this happens almost immediately, and the connection takes a further
    minute or so to time out.

    Any suggestions?

    Thanks

    Chris
