So here is the next question, is this a valid subtype: "225_0_10_100._ftp._tcp"? I think that avahi insists on having a leading underscore but is it an avahi think or is it in the zeroconf spec?

It's just using the DNS-SD subtype feature. You're browsing "_ftp._tcp" with a subtype of "225_0_10_100". All packets are still being sent to the link-local Multicast address assigned to mDNS (224.0.0.251).

They did came up initially with zeroconf, right? But nevermind, I guess I'll have to snoop the multicast address myself. -----Oorspronkelijk bericht----- Van: <a class="moz-txt-link-abbreviated" href="mailto:avahi-bounces@lists.freedesktop.org">avahi-bounces@lists.freedesktop.org</a> [<a class="moz-txt-link-freetext" href="mailto:avahi-bounces@lists.freedesktop.org">mailto:avahi-bounces@lists.freedesktop.org</a>] Namens Lennart Poettering Verzonden: maandag 16 maart 2009 17:03 Aan: <a class="moz-txt-link-abbreviated" href="mailto:avahi@lists.freedesktop.org">avahi@lists.freedesktop.org</a> Onderwerp: Re: [avahi] browsing for services on a specific multicast address On Mon, 16.03.09 13:46, Alon Noy (<a class="moz-txt-link-abbreviated" href="mailto:Alon.Noy@ilsemedia.nl">Alon.Noy@ilsemedia.nl</a>) wrote: </pre> <blockquote type="cite"> <pre wrap="">I don't have any documentation to contribute but I can explain the logic: A large amount of file servers (it's not really ftp) are being split into clusters, when a file is added to one server in the cluster it is being replicated on different nodes within the cluster (for </pre> </blockquote> <pre wrap="">availability </pre> <blockquote type="cite"> <pre wrap="">and backup).

I see no reason to support a different address. I am sorry, but I don't really understand what you are trying to do. I kind of get the feeling you are misusing the mcast functionality for something where VLANs should be used instead.
