This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigE8E5B60124D080CEC28E3C00 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Dear colleagues, I have a strange question about our way of handling INADDR_BROADCAST, the behavior looks different from all other operating systems I have tried, except Mac OS X ;-) By ping'ing 255.255.255.255 from FreeBSD (mostly RELENG_6 with some unrelated patches) or Mac OS X, I got response from another subnet (I guess that there is some configuration problem in the network, though), but no boxes (running various operating systems) on local network responds the ping. However, with OpenBSD, Linux and Windows, ping'ing 255.255.255.255 would get response from local network. Just curious why there is such difference. Literally, I think INADDR_BROADCAST is supposed to reach local network nodes, no?
