Could you try the gated from Raw Hide? (Do "rpm --rebuild gated*.src.rpm"). Several problems were fixed in that version. Multicast is enabled and working on i386/sparc (and I believe alpha). I could not reproduce this problem using the example gated.conf and the following packages gated-3.5.10-1 kernel-2.0.36-0.1kfd You might want to make sure that the ethernet driver that you are using supports multicast. Please reopen this bug if you have further information. Ethernet driver is tulip, definitely supports multicast. Kernels tried are all stock kernels as delivered by RedHat. If your build had it enabled, it's there. I see problems on all systems I've tried with 5.2, with both XNTPD and GATED. This is true on systems I've set up, and on those at some of my clients. I have not yet tried building a custom kernel to see if that would solve the problem. On the gated matter, one of my clients solved the problem by using the gated from RHL 5.1 instead of the one from 5.2, and that ran OK. We haven't run similar tests on XNTP yet. FWIW; Red Hat currently uses multicast NTP to sync all our 5.2 machines. What happens if you ping 224.0.0.1? Pings to 224.0.0.1 do indeed result in ping responses from all hosts which should be subscribed to the ALL-HOSTS multicast group. So, it looks like multicast is there. Could you send me sample ntp config files from your working machines? I'll give them a try and see if they work here. The sample files, as shipped, resulted in error messages related to multicast. I reopened a related bug on xntpd and added comments there. NTP will indeed operate, despite a couple of error messages at startup. Gated remains a problem, however. For now in the critical case, we're using the gated RPM from 5.1, since that works (including multicast). Seems like there's something specifically wrong with gated, or perhaps it doesn't have the extra code xntpd has to work around the multicast allocation problem reported in the xntpd error messages (if that's indeed what xntpd is trying to say). Please try the Raw Hide gated*src.rpm -- several problems have been fixed there. You will need to do "rpm --rebuild gated*src.rpm" in order to install since Raw Hide uses glibc-2.1. Otherwise, since I can't reproduce the problem and have no further information about how to reproduce the problem or even if a problem still exists :-), I'm gonna close this. |
