hi,

unfortunately this doesn't work neither. maybe i describe the situation more
exactly:

- on the server the sshd runs
- another machine has to establish a connection
- when connecting, it shall open a tunnel on a port (e.g. 10000)
- on that port i have to establlich a tcp-forwarding connection
- over that port, an application on the server has to exchange information
with the client

in the ssh-manual this feature is described with the option -R:
...
     -R  port:host:hostport
             Specifies that the given port on the remote (server) host is to
             be forwarded to the given host and port on the local side.
This
             works by allocating a socket to listen to port on the remote
             side, and whenever a connection is made to this port, the
connec-
             tion is forwarded over the secure channel, and a connection is
             made to host port hostport from the local machine.  Port
forward-
             ings can also be specified in the configuration file.
Privileged
             ports can be forwarded only when logging in as root on the
remote
             machine.
...

so i tried "ssh -f -n -R 10000:host:port user AT host"./sleep 3600" ", for
establishing a connection for 3600 seconds.

what else do i have to configure ind the sshd_config or ssh_config.

any help would be very kind, cause i don't know what to do else.

matthias

AFAICS you want to use -L.

  ssh -L 10000:host:port user AT host...
