--- Comment #55 from Bruno Jesus 00cpxxx@gmail.com 2013-08-25 18:53:04 CDT --- (In reply to comment #53) No, uTorrent does not set SO_REUSEADDR by default. We were speculating about forcing that option on every socket that is created. The problem is that windows ignores TIME_WAIT and allows any program to bind to the port, while in linux the timings are strictly followed.
