How do I make a UDP request to a torrent tracker?

Cody Fendant has asked for the wisdom of the Perl Monks concerning the following question:

This page contains the details of a well-known torrent tracker:

http://coppersurfer.tk/

Which advises us to use UDP and access udp://tracker.coppersurfer.tk:6969/announce -- how would I do that with Perl?

This node shows how to send something to a UDP host (no path is given) but I want to do something more like a HTTP get() request and get back a stream of data.

How do I do that?

question based on a misunderstanding

Part of the ~~now (erased)~~ question is how to do something like a request/reply flow as HTTP has over UDP. As UDP is not TCP, there is no concept of a "connection" for UDP. So I expect that most UDP-based protocols will simulate that "connection" by actively sending a separate packet to the originating IP address in response to receiving an UDP packet.	[reply]

This deletion violates PM standards... if for no other reason than that your "misunderstanding" may be illuminating to some future reader... especially if the OP is restored and you edit it to explain what you now believe. Update: jdporter advises the original has been restored. Spirit of the Monastery	[reply]

Self promotion time! It's kinda dated (pre-Moose and hand rolled event loop era) but Net::BitTorrent supports UDP trackers. Eventually, that'll be based on IO::Async.	[reply]
