@#22: Seth Arnold,

I agree that there must be better solution. The easiest may be just changing in network-manager the configuration for dnsmasq by omitting the option --cache-size=0.
But: I am not package maintainer or developer for whoopsie, network-manager or dnsmasq and I do not fully understand your technical hints. I am just an Ubuntu user affected by this annoying bug open for more than 2 1/2 years. I do not know why whoppsie must look at DNS every minute and why network-manager starts a caching DNS forwarder without cache. I just want get rid of this dammed traffic. As far as I can see, my wrapper script helps. I will use it until the package maintainers and developers  for whoopsie, network-manager or dnsmasq provide a better solution of their choice.

Title:
  Constant dns traffic for daisy.ubuntu.com

Status in Ubuntu error tracker client (whoopsie):

Bug description:
  Watching GNetworkMonitor's network-changed signal causes constant DNS
  traffic.

  Andy Whitcroft points out that the NETLINK_ROUTE socket set up by
  GNetworkMonitor will fire events every time an ARP entry appears or
  disappears.

  Unfortunately, we currently need an additional layer of connectivity
  checking because checking NetworkManager's state for CONNECTED_GLOBAL
  is not enough to know whether we're really online. Ubuntu does not yet
  use the NetworkManager connectivity check [1].

  The likely solution to this bug is a replacement for GNetworkMonitor
  in whoopsie.

  Original report follows:

  Every few seconds, I see a dns query for daisy.ubuntu.com. After
  removing whoopsie, the traffic goes away.
