NAME ^

POE::Component::Client::SOCKS - SOCKS enable any POE Component

SYNOPSIS ^

Spawning a SOCKS broker:

   use strict;
   use POE qw(Component::Client::SOCKS Wheel::ReadWrite Filter::Line);
   use Data::Dumper;
   
   my $poco = POE::Component::Client::SOCKS->spawn( options => { trace => 0 } );
   
   POE::Session->create(
        package_states => [
          'main' => [ qw(_start _success _failed _conn_input _conn_error) ],
        ],
        heap => { sockify => $poco },
        options => { trace => 0 },
   );
   
   $poe_kernel->run();
   exit 0;
   
   sub _start {
     my ($kernel,$heap) = @_[KERNEL,HEAP];
     $heap->{sockify}->connect( 
        SocksProxy => '127.0.0.1',
        RemoteAddress => 'cou.ch',
        RemotePort => 6667,
        SuccessEvent => '_success',
        FailureEvent => '_failed',
     );
     return;
   }
   
   sub _success {
     my ($heap,$args) = @_[HEAP,ARG0];
     warn Dumper( $args );
     $heap->{wheel} = POE::Wheel::ReadWrite->new(
        Handle => $args->{socket},
        Filter => POE::Filter::Line->new(),
        InputEvent => '_conn_input',
        ErrorEvent => '_conn_error',
     );
     return;
   }
   
   sub _failed {
     warn Dumper( $_[ARG0] );
     return;

DESCRIPTION ^

POE::Component::Client::SOCKS provides SOCKSification services to other POE sessions and components. It accepts connection requests and deals with all the SOCKS negotiation on your behalf. It returns either a SuccessEvent which will have a shiny socket handle for you to use or an FailureEvent which should say what went wrong.

SOCKS 4 and 4a based servers are supported.

CONSTRUCTORS ^

One may start POE::Component::Client::SOCKS in two ways. If you spawn it creates a session that can then broker lots of SOCKS connections on your behalf. Or you may use 'connect' and 'bind' to broker one connection instance.

  POE::Component::Client::SOCKS->spawn( ... );

  POE::Component::Client::SOCKS->connect( ... );

  POE::Component::Client::SOCKS->bind( ... );
spawn

Creates a new POE::Component::Client::SOCKS session that may be used lots of times. Takes the following optional parameters:

  'alias', set an alias that you can use to address the component later;
  'options', a hashref of POE session options;

Returns an object.

connect

Creates a one-shot POE::Component::Client::SOCKS session that will connect to a SOCKS server and negotiate a CONNECT. Takes the following parameters ( mandatory ones are indicated ):

  'SocksProxy', the SOCKS server that you want to connect to (Mandatory);
  'RemoteAddress', the address that you want the SOCKS proxy to connect to (Mandatory);
  'RemotePort', the port that you want the SOCKS proxy to connect to (Mandatory);
  'SuccessEvent', the event that will be sent when a CONNECT is successful (Mandatory);
  'FailureEvent', the event to send when a CONNECT is not successful or errored (Mandatory);
  'SocksPort', the SOCKS server port to connect to (default is 1080);

Takes any number of arbitary parameters that will passed through to the SuccessEvent/FailureEvent. Please use underscore prefixes to avoid future API changes.

bind

Creates a one-shot POE::Component::Client::SOCKS session that will connect to a SOCKS server and negotiate a BIND. Takes the following parameters ( mandatory ones are indicated ):

  'SocksProxy', the SOCKS server that you want to connect to (Mandatory);
  'RemoteAddress', the address that you want the SOCKS proxy to connect to (Mandatory);
  'RemotePort', the port that you want the SOCKS proxy to connect to (Mandatory);
  'SuccessEvent', the event that will be sent when a BIND is successful (Mandatory);
  'FailureEvent', the event to send when a BIND is not successful or errored (Mandatory);
  'SocksPort', the SOCKS server port to connect to (default is 1080);

Takes any number of arbitary parameters that will passed through to the SuccessEvent/FailureEvent. Please use underscore prefixes to avoid future API changes.

INPUT EVENTS ^

bind

Connect to a SOCKS server and negotiate a BIND. Takes the following parameters ( mandatory ones are indicated ):

  'SocksProxy', the SOCKS server that you want to connect to (Mandatory);
  'RemoteAddress', the address that you want the SOCKS proxy to connect to (Mandatory);
  'RemotePort', the port that you want the SOCKS proxy to connect to (Mandatory);

Takes any number of arbitary parameters that will passed through to the SuccessEvent/FailureEvent. Please use underscore prefixes to avoid future API changes.

shutdown

Terminates the component. Disconnects any pending SOCKS requests.

OUTPUT EVENTS ^

The component returns either a SuccessEvent or an FailureEvent, you specify the events in your session that you wish to be triggered for each type. ARG0 will be a hashref. See details following.

Any arbitary parameters passed though will be in the returned hashref.

SuccessEvent

All the parameters passed to 'connect' or 'bind' will be present, plus:

  'socket', the socket handle of the connection to the SOCKS server;
  'socks_response', an arrayref consisting of the reply from the SOCKS server:
                    the result code, the dest IP and the dest port.

For a BIND, the dest IP and the dest port are the address and port that the SOCKS server has opened for listening.

FailureEvent

Generated if something went wrong, either a connection could not be established with the SOCKS server or the SOCKS server rejected our request.

If a connection to the SOCKS server could not be established then the following will exist:

  'sockerr', an arrayref containing the operation, errnum and errstr as returned by 
             POE::Wheel::SocketFactory;

If the SOCKS server rejected our request for some reason the following will exist:

  'socks_unknown', a string error message. This is generated if we get a garbled response
                   from the SOCKS server;
  'socks_error', an integer response from the SOCKS server, indicating that it has rejected the
                 request.
