-pport
              The port tcp_relay will listen for connections on.
       -s
              If  this option is given, only a single connection at a time will be handled.  Otherwise tcp_relay
              will fork a new copy of itself for each incoming connection and go on to accept new connections.
       -hhost
              Connections from this host will be allowed.  Several of these may be supplied.

tcp_relay -p port [-s] -h host ... remotehost[:port]
