Hello. We are running dnsmasq version /usr/sbin/dnsmasq --version Dnsmasq version 2.76 Copyright (c) 2000-2016 Simon Kelley Compile time options: IPv6 GNU-getopt no-DBus no-i18n no-IDN DHCP DHCPv6 no-Lua TFTP no-conntrack ipset auth no-DNSSEC loop-detect inotify
We run dnsmasq in our kubernetes (https://kubernetes.io/) clusters to perform DNS resolution for the container based services running in the cluster. I wrote up a bigger picture overview of our situation here http://stackoverflow.com/q/44030167/6067470. The key points are that the applications running in our clusters experience intermittent name resolution errors. At the same time that 1 or more applications have a name resolution error we get connection refused errors from an application that is querying dnsmaq for it's metrics (eg: dig +short chaos txt cachesize.bind). I'm thinking that the DNS failures we are seeing is that dnsmasq is refusing the connection. I'm hoping someone can point me in a direction to get to the root of these issues. The only thought I have is to run dnsmasq in debug mode in the hopes that when connections are not being accepted something will get logged that would be a clue as to why this is happening. I'm wondering if that's a sound approach or if anyone has alternate ideas for me to move this situation forward. Thanks for listening! _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
