SO_BROADCAST controls sending, not receiving. This definition comes from the BSD sockets API, even Stevens TCP/IP Illustrated Volume 2, page 437, figure 15.4 clearly states that SO_BROADCAST means "socket can send broadcast messages". It says nothing about receiving and the BSD implementation matches that description, as does Linux.
This has been brought up before, search for the subject "UDP Broadcasts not delivered to IP address" in the linux-net list archives for one such thread. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
