POE::Component::Server::Echo - A POE component that implements an RFC 862 Echo server.
use POE::Component::Server::Echo; my $self = POE::Component::Server::Echo->spawn( Alias => 'Echo-Server', BindAddress => '127.0.0.1', BindPort => 7777, options => { trace => 1 }, );
POE::Component::Server::Echo implements a RFC 862 http://www.faqs.org/rfcs/rfc862.html TCP/UDP echo server, using POE. The component encapsulates a class which may be used to implement further RFC protocols.
spawn
Takes a number of optional values:
"Alias", the kernel alias that this component is to be blessed with; "BindAddress", the address on the local host to bind to, defaults to L<POE::Wheel::SocketFactory|POE::Wheel::SocketFactory> default; "BindPort", the local port that we wish to listen on for requests, defaults to 7 as per RFC, this will require "root" privs on UN*X; "options", should be a hashref, containing the options for the component's session, see POE::Session for more details on what this should contain.
sockname_tcp
Takes no arguments. Returns a list consisting of the socket port and address of the TCP listening socket as returned by Socket's sockaddr_in function.
sockname_udp
Takes no arguments. Returns a list consisting of the socket port and address of the UDP listening socket as returned by Socket's sockaddr_in function.
shutdown
Takes no arguments. Shuts down the component gracefully, terminating all listeners and disconnecting all connected clients.
