--- Comment #3 from Juan Lang juan_lang@yahoo.com 2010-08-26 11:33:15 --- In general, Wine doesn't do anything special here: winsock calls are passed more or less unmodified to the sockets code in Linux, so this may be a difference in behavior between Linux and Windows, rather than a Wine bug. Just in case, could you attach a +iphlpapi,+winsock trace?
