Good idea!
Regardless, this has nothing to do with the problem in that for some reason that firewall computer is not skipping past unreachable DNS servers. I know...for that I suggested:
Maybe the higher one is considered authoritative so lower ones don't get checked?
nscd gives more control, but is intended for local resolving...
i.e. has the authority or the DNS versions on the queried servers changed?
Has your querying software on your system changed? I.e. maybe it used to roll over, but now does not?
Does a failure in ipv6 resolution lead to rollovers to ipv4?
Wouldn't ipv6 failures fail-over to other ipv6 responders and ipv4 failures fail-over to other ipv4 responders?
I know initially it is often the case that queries are sent out to ipv6 and ipv4 DNS resolvers at the same time to get back which over comes back first. But I wonder if that advice may have changed with the other stuff I was mentioning. I.e. if they were worried about higher ipv6 overhead where it really wan't helping because underlying protocol was ipv4, then they might not being get sent out in parallel or using cross-protocol failovers (just a possibility)....
I copied the config files from the old computer, running 11.4, to the new and it was running fine for about 2 weeks. Then after I rebooted, it was no longer working. What changed? There were some updates that installed a couple of days earlier, but I don't recall what. I am also running dnsmasq on this computer, as I did on the old one. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
