NAME

POE::Component::Client::Ident - A component that provides non-blocking ident lookups to your sessions.

SYNOPSIS

   use POE::Component::Client::Ident;

   my $poco_obj = POE::Component::Client::Ident->spawn ( 'Ident-Client' );

   $kernel->post ( 'Ident-Client' => query => Socket => $socket );

   $kernel->post ( 'Ident-Client' => query => PeerAddr => '10.0.0.1', 
                                              PeerPort => 2345,
                                              SockAddr => '192.168.1.254',
                                              SockPort => 6669,
                                              BuggyIdentd => 1,
                                              TimeOut => 30 );

DESCRIPTION

POE::Component::Client::Ident is a POE component that provides non-blocking Ident lookup services to other components and sessions. The Ident protocol is described in RFC 1413 <http://www.faqs.org/rfcs/rfc1413.html>.

The component takes requests in the form of events, spawns POE::Component::Client::Ident::Agent sessions to perform the Ident queries and returns the appropriate responses to the requesting session.

CONSTRUCTOR

spawn
Takes one argument, a kernel alias to christen the new component with.

Returns an object.

METHODS

These methods are available on the poco object returned by spawn().
session_id
Returns the component's session ID.
shutdown
Takes no arguments. Causes the component to terminate gracefully. Any pending Ident::Agent components that are running will be closed without returning events.

INPUT

The component accepts the following events:
query
Takes either the arguments: 

  "PeerAddr", the remote IP address where a TCP connection has originated; 
  "PeerPort", the port where the TCP has originated from;
  "SockAddr", the address of our end of the connection; 
  "SockPort", the port of our end of the connection;

OR: 

  "Socket", the socket handle of the connection, the component will work out all 
  the details for you. If Socket is defined, it will override the settings of the 
  other arguments.

See the documentation for Ident-Agent for extra parameters you may pass.

shutdown
Takes no arguments. Causes the component to terminate gracefully. Any pending Ident::Agent components that are running will be closed without returning events.

OUTPUT

The events you can expect to receive having submitted a 'query'.

All the events returned by the component have a hashref as ARG0. This hashref contains the arguments that were passed to the component. If a socket handle was passed, the hashref will contain the appropriate PeerAddr, PeerPort, SockAddr and Sock Port.

ident_client_reply
Returned when the component receives a USERID response from the identd. ARG0 is hashref, ARG1 is the opsys field and ARG2 is the userid or something else depending on whether the opsys field is set to 'OTHER' ( Don't blame me, read the RFC ).
ident_client_error
Returned when the component receives an ERROR response from the identd, there was some sort of communication error with the remote host ( ie. no identd running ) or it had some other problem with making the connection to the other host. No matter. ARG0 is hashref, ARG1 is the type of error.
