Hi Daniel, I've done a quick test on Windows using and old version of Nping to generate UDP packets to addresses like 192.255.255.255 and I can confirm it works fine. Note that the version I'm using is old and does no SO_BROADCAST setsockopt at all. So yes, it looks like windows does allow targeting broadcast addresses even if you don't set SO_BROADCAST on the socket. Luis MartinGarcia. PS: MSDN documentation talks about SO_BROADCAST ("SO_BROADCAST, BOOL, Enables transmission and receipt of broadcast messages on the socket.") but does not mention whether it is set by default or not. <http://msdn.microsoft.com/en-us/library/ms740476%28VS.85%29.aspx>
What happens if you getsockopt(SO_BROADCAST) on Windows? That would check if it's set by default. David Fifield _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
