Re: ncat broadcast support?

[Luis MartinGarcia <luis.mgarc () gmail com>]

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.

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.
