To: freebsd-net@FreeBSD.org, freebsd-hackers@FreeBSD.org Message-id: <20000629005801.A251@broccoli.no-support.loc> MIME-version: 1.0 Content-type: text/plain; charset=us-ascii Content-disposition: inline Content-transfer-encoding: 7BIT User-Agent: Mutt/1.2i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Good morning, I got the impression that the socket option IP_MULTICAST_LOOP has no effect on 4.0-STABLE. Multicast packages are not looped back to the originating host. Looping back should be the default behavior of the socket API (Stevens, Unix Network Programming). I tried to explicitly switch it on with IP_MULTICAST_LOOP, but it didn't work either. Of course the socket is subscribed to the group (IP_ADD_MEMBERSHIP). Am I missing something or should this be a bug?
