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 connections
     on  port on the local host and when a client connects makes a connection 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-di-
     rectional 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 features
     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.  (de-
	    fault 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.  (de-
	    fault 1800)

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