UDP Tracker Scrape

[eremini]

Hi,

This is more of a feature request. Could you please consider making it possible to scrape a UDP tracker for numbers, as a lot of trackers seem to be switching to UDP only model (openbittorrent being the biggest one). Since you now use CURL this should be no problem.

Cheers.

Hello, Interesting point! Any idea where i could find the spec? I have no idea how to do that...

Hi,

Good to hear that you're interested. The oficial spec is located here: http://xbtt.sourceforge.net/udp_tracker_protocol.html

Let me know if you need any other info, help or testing.

Cheers.

Thanks for the link, now i have to find some time to try implementing this

[adriengibrat]

Ok, i've just look deeper into some doc (the link you posted + http://www.rasterbar.com/products/libtorrent/udp_tracker_protocol.html) It seems I have to implement Connection, Scraping, Error & eventualy Authentification... using sockets. And Curl isn't any help here!

[eremini]

Yeah you're right I forgot you got to use sockets in this case, so I guess it gets more complicated :/

Example of UDP communication from php.net <?php $frame = array( array(1,1,0,1,1,1,1,1,0,1,1,1,1,1,0,1,1,1), array(1,1,0,1,1,1,1,1,0,1,1,1,1,1,0,1,1,1), array(1,1,0,1,1,0,1,1,0,1,1,0,1,1,0,1,1,1), array(1,1,0,1,1,0,1,1,0,1,1,0,1,1,0,1,1,1), array(1,1,0,1,1,0,1,1,0,1,1,0,1,1,0,1,1,1), array(1,1,0,1,1,0,1,1,0,1,1,0,1,1,0,1,1,1), array(1,1,0,1,1,1,1,1,0,1,1,1,1,1,0,1,1,1), array(1,1,0,1,1,1,1,1,0,1,1,1,1,1,0,1,1,1) );

send_frame($frame, 1500);

/**

• Sends 18x8 MCUF-UDP packet to target host. *
• see also:

• @param array $frame 18x8 '0' or '1'

very interesting code: https://github.com/johannes85/PHP-Torrent-Scraper

[eremini]

Ah nice, it's not as complicated as I thought, perhaps you can reuse some of his code in your way

[johannes85]

The easyest way to do it would be to implement some kind of a plugin system so a external scraper class (like mine) could be used. Some Dependency Injection stuff or so. But then there is the question if you want to extend your compact class to a bigger system? A torrent framework which can handle all torrent related tasks would be very useful.

[adriengibrat]

Sorry I still haven't done anything about that! If anyone want to submit a patch or a push, it's always welcome.

I'm not using torrent very often, I just did that class for fun... So no torrent Framework in sight.

I am willing to make a donation even if someone is willing to implement UDP scraping into this code!

[adriengibrat]

As soon as i got some time i'm willing to implement UDP scraping + DHT methods using UDP transfert protocol. I'm open for any help as I got only few spare time (got a new job 2 weeks ago and a beautifull son 3 days ago!). Anyone wanting to help on this, please clone and start coding ;)

[eremini]

I guess no progress on this yet adriengibrat . I'd honestly be willing to donate to someone if they got this done by now, I simple don't have the time or the skill anymore.

Hey adriangibrat! Here is what I found for udp scraping. https://github.com/ZonD80/Kinokpk.com-releaser/blob/3.30/Kinokpk.com_releaser_v.3.30/upload/include/benc.php

It would be great if you could add udp to your class. Thanks

[robinlahtinen]

Updates?

[adriengibrat]

PR always welcome. I dont have time/motivation to do it, but i will happily review & merge.

[darkalchemy]

I added this using the scrapeer class, its in the changes/demo branch. 8cb60d8

[teamcoltra]

I notice that at least some if not all of @darkalchemy 's commit has not made it to the master branch. Did this feature get implemented differently or is there something holding this up?
