vanessa_socket_pipe - Trivial TCP/IP pipe based on libvanessa_socket
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-directional
Uses include enabling connections to specific ports on hosts behind a packet
This code is intended primarily as an example of how many of the features of
- Maximum number of connections to accept simultaneously. A value of zero
sets no limit on the number of simultaneous connections. (default 0)
- Turn on verbose debuging to stderr.
- Display this message.
- Port to listen on. (mandatory)
- Address to listen on. May be a hostname or an IP address. If not defined
then listen on all local addresses.
- Turn off lookup of hostnames and portnames. That is, hosts must be given
as IP addresses and ports must be given as numbers.
- Define a port to connect to. If not specified -l|--listen_port will be
- Define host to connect to. May be a hostname or an IP address.
- Only log errors. Overriden by -d|--debug.
- Idle timeout in seconds. Value of zero sets infinite timeout. (default
- Default value for binary flags is off.
-L|--listen_port and -o|--outgoing_host must be defined.
