How do I disable local DNS caching?

  • 772

I have a small private LAN with 6 Ubuntu systems. To improve performance and simplify maintenance I implemented a DNS server on my Debian firewall/router (dig shows 0ms on repeat lookups).

Will I be able to disable the new local DNS cache on my Ubuntu systems during or after the release-upgrade?

Reference:

lan dnsmasq

    To quote my own blog post:

    This dnsmasq server isn’t a caching server for security reason to avoid risks related to local cache poisoning and users eavesdropping on other’s DNS queries on a multi-user system.

    So there's nothing to disable
