view listener.h @ 296:6b41e2cbf071 dbclient-netcat-alike
A hack to make dbclient to tcp forwarding netcat style.
eg
./dbclient -i testkey -L 1234:remotehost:remoteport tunnelhost
will ssh to tunnelhost (using testkey, there's no way to ask for a password)
and then tcpfwd to remotehost:remoteport on stdin/stdout.
There's no way to give a cmdline password, so -i for a keyfile will have to do.
Yet another reason for agent forwarding.
The 1234 is a dummy var, I think it has to be a valid portnumber though.
