POE::Component::Client::Ident::Agent(3pm) User Contributed Perl Documentation POE::Component::Client::Ident::Agent(3pm) NAME
POE::Component::Client::Ident::Agent - A component to provide a one-shot non-blocking Ident query. SYNOPSIS
use POE::Component::Client::Ident::Agent; my $poco = POE::Component::Client::Ident::Agent->spawn( PeerAddr => "192.168.1.12", # Originating IP Address PeerPort => 12345, # Originating port SockAddr => "192.168.2.24", # Local IP address SockPort => 69, # Local Port Socket => $socket_handle, # Or pass in a socket handle IdentPort => 113, # Port to send queries to on originator # Default shown BuggyIdentd => 0, # Dealing with an Identd that isn't # RFC compatable. Default is 0. TimeOut => 30, # Adjust the timeout period. Reference => $scalar # Give the component a reference ); sub _child { my ($action,$child,$reference) = @_[ARG0,ARG1,ARG2]; if ( $action eq 'create' ) { # Stuff } } sub ident_agent_reply { } sub ident_agent_error { } DESCRIPTION
POE::Component::Client::Ident::Agent is a POE component that provides a single "one shot" look up of a username on the remote side of a TCP connection to other components and sessions, using the ident (auth/tap) protocol. The Ident protocol is described in RFC 1413 <http://www.faqs.org/rfcs/rfc1413.html>. The component implements a single ident request. Your session spawns the component, passing the relevant arguments and at some future point will receive either a 'ident_agent_reply' or 'ident_agent_error', depending on the outcome of the query. If you are looking for a robust method of managing Ident::Agent sessions then please consult the documentation for POE::Compo- nent::Client::Ident, which takes care of Agent management for you. CONSTRUCTOR
spawn 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, except for: "IdentPort", which is the port on the remote host where we send our ident queries. This is optional, defaults to 113. You may also specify BuggyIdentd to 1, to support Identd that doesn't terminate lines as per the RFC. You may also specify TimeOut between 5 and 30, to have a shorter timeout in seconds on waiting for a response from the Identd. Default is 30 seconds. Optionally, you can specify Reference, which is anything that'll fit in a scalar. This will get passed back as part of the response. See below. Returns an POE::Component::Client::Ident::Agent object, which has the following methods. METHODS
session_id Returns the POE session ID of the component. shutdown Terminates the component. OUTPUT
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 SockPort. If the component was spawned with a Reference parameter, this will be passed back as a key of the hashref. The following events are sent to the calling session by the component: ident_agent_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_agent_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. AUTHOR
