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 someonecentral-server &
(nn = 01..50)
Then, from the central server, use:
$ ssh -p 123nn localhost
to connect to remote server nn.
Cheers
Steffen.
