(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.
I still don't see any security implications in enabling SO_REUSEADDR by default.
Windows has always allowed that and I don't see a single security problem arising due to this feature. What's so different about Linux? I've no idea at all.
