VANESSA_SOCKET_PIPE(1)	    General Commands Manual	VANESSA_SOCKET_PIPE(1)

NAME
       vanessa_socket_pipe - Trivial TCP/IP pipe based on libvanessa_socket

SYNOPSIS
       vanessa_socket_pipe [options]

DESCRIPTION
       A TCP/IP	pipe is	a user space programme that listens for	TCP/IP connec-
       tions on	port on	the local host and when	a client connects makes	a con-
       nection	to a TCP port, possibly	on another host. Once both connections
       are established data sent on one	connection is relayed  to  the	other,
       hence forming a bi-directional pipe.

       Uses  include  enabling connections to specific ports on	hosts behind a
       packet filter.

       This code is intended primarily as an example of	how many of  the  fea-
       tures of	libvanessa_socket work.

OPTIONS
       -c|--connection_limit:
	      Maximum  number of connections to	accept simultaneously. A value
	      of zero sets no limit on the number of simultaneous connections.
	      (default 0)

       -d|--debug:
	      Turn on verbose debuging to stderr.

       -h|--help:
	      Display this message.

       -L|--listen_port:
	      Port to listen on. (mandatory)

       -l|--listen_host:
	      Address to listen	on. May	be a hostname or an  IP	 address.   If
	      not defined then listen on all local addresses.

       -n|--no_lookup:
	      Turn  off	lookup of hostnames and	portnames. That	is, hosts must
	      be given as IP addresses and ports must be given as numbers.

       -O|--outgoing_port:
	      Define a port to connect to. If not  specified  -l|--listen_port
	      will be used.

       -o|--outgoing_host:
	      Define  host to connect to.  May be a hostname or	an IP address.
	      (mandatory)

       -q|--quiet:
	      Only log errors. Overriden by -d|--debug.

       -t|--timeout:
	      Idle timeout in seconds.	Value of zero sets  infinite  timeout.
	      (default 1800)

       Notes: Default value for	binary flags is	off.
	      -L|--listen_port and -o|--outgoing_host must be defined.
