    On all of the 50 remote servers create SSH DSA keys (as yourself) and
    add their public parts to file ~someone/.ssh/authorized_keys on the
    central server. Then run something like:

    [yourself ~]$ ssh -N -R 123nn:127.0.0.1:22 someone@central-server &

    (nn = 01..50)

    Then, from the central server, use:

    $ ssh -p 123nn localhost

    to connect to remote server nn.

    Cheers
    Steffen.
