Re: [Dnsmasq-discuss] [PATCH] fix entries in /etc/hosts disabling static leases
Hi, I tried to install this patch manually to my 2.80 and got a segfault that prevented dnsmasq running. I also tried git cloning the master and installing that instead but got the same result. Any suggestions? I could really use this fix.

[Dnsmasq-discuss] IXFR requests and how they are handled
Hello I was trying to use dnsmasq as a master with unbound as secondaries. After some debugging (https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=4219), I realized that IXFR is not handled by dnsmasq (AXFR is - and works fine). It seems that the request just hangs and timeouts. Would it be possible to appropriately respond to IXFR queries so that the requesting server knows to fallback to AXFR? I am trying at the same time to see whether the "timeout" case could not be gracefully handled as well on unbound side (they only handle rejection) ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
