NAME

       redir - redirect tcp connections

SYNOPSIS

       redir  [--laddr=incoming.ip.address]  [--caddr=host] [--debug] [--syslog] [--name=str] [--timeout=n] [--bind_addr=my.other.ip.address] [--ftp=type]
       [--transproxy] [--connect=host:port] --lport=port --cport=port [--bufsize=n] [--max_bandwidth=n] [--random_wait=n] [--wait_in_out=n]
       redir --inetd [--caddr=host] [--debug] [--syslog] [--name=str] [--timeout=n] [--ftp=type] [--transproxy] [--connect=host:port] --cport=port
       [--bufsize=n] [--max_bandwidth=n] [--random_wait=n] [--wait_in_out=n]

DESCRIPTION

       Redir redirects tcp connections coming in to a local port to a specified address/port combination.

       It may be run either from inetd or as a standalone daemon.  Depending on how redir was compiled, not all options may be available.

OPTIONS

       --lport
	      Specifies port to listen for connections on (when not running from inetd)

       --laddr
	      IP address to bind to when listening for connections (when not running from inetd)

       --cport
	      Specifies port to connect to.

       --caddr
	      Specifies remote host to connect to. (localhost if omitted)

       --inetd
	      Run as a process started from inetd, with the connection passed as stdin and stdout on startup.

       --debug
	      Write debug output to stderr or syslog.

       --name Specify program name to be used for TCP wrapper checks and syslog logging.

       --timeout
	      Timeout and close the connection after n seconds of inactivity.

       --syslog
	      Log information to syslog.

       --bind_addr
	      Forces redir to pick a specific address/interface to bind to when it listens for incoming connections.

       --ftp  When  using  redir  for  an FTP server, this will cause redir to also redirect ftp connections.  Type should be specified as
	      either "port", "pasv", or "both", to specify what type of FTP connection to handle.  Note that --transproxy often makes  one
	      or the other (generally port) undesirable.

       --transproxy
	      On  a linux system with transparent proxying enabled, causes redir to make connections appear as if they had come from their
	      true origin.  (see /usr/share/doc/redir/transproxy.txt)

       --connect
	      Redirects connections through an HTTP proxy which supports the CONNECT command.  Specify the address and port of	the  proxy
	      using --caddr and --cport.  --connect requires the hostname and port which the HTTP proxy will be asked to connect to.

       --bufsize n
	      Set  the	bufsize (defaut 4096) in bytes. Can be used combined with --max_bandwidth or --random_wait to simulate a slow con-
	      nection.

       --max_bandwidth n
	      Reduce the bandwidth to be no more than n bits/sec.  The algorithme is basic, the goal is to simulate a slow connection,	so
	      there is no pic acceptance.

       --random_wait n
	      Wait  between  0	and  2	x  n  milliseconds before each "packet". A "packet" is a bloc of data read in one time by redir. A
	      "packet" size is always less than the bufsize (see also --bufsize).

       --wait_in_out n
	      Apply --max_bandwidth and --random_wait for input if n=1, output if n=2 and both if n=3.

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-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 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.
	      (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.
