Hello guys,
After testing I decide to write my patch to bittorrent
GET commands from xt_ipp2p.c because old procedure is
useless for modified and/or private trackers. teh new
works fine but maybe someone can rewrite it to better C
(yeah, im C/C++ n00b ;)
btw. info_hash may be 3rd argument, passkey (private trackers)
may be 1st argument (or not) etc. etc. so we need to search.
