In The Optimist's Daughter, we are in the South once more, but a South where real distinctions are made between Texas and Mississippi, and Mississippi and West Virginia.
Host-Level Cache Host Settings. The cache host settings stored on each cache host are functional and are related to settings required for the software to run; for example, they set where the cache host can find the cluster configuration storage location and how log sinks should be configured.
In order to configure dnsmasq to act as cache for the host on which it is running, put nameserver 127.0.0.1 in /etc/resolv.conf to force local processes to send queries to dnsmasq. Then either specify the upstream servers directly to dnsmasq using --server options or put their addresses real in another file, say /etc/resolv.dnsmasq and run dnsmasq with the -r /etc/resolv.dnsmasq option.
