And it's _still_ a red herring. I just booted a !CONFIG_IGMP kernel on my workstation and NTP is running just fine (as is IPv6). Even though ntpd has a configure test for multicast and can be built without multicast support at all, it isn't even necessary to build it that way -- the stock Fedora build of it works just fine. (Actually, I never managed to get ntpd to work _with_ multicast, but that's a different issue... :) -- dwmw2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
