[Bug 991481] Re: Constant dns traffic for daisy.ubuntu.com

[Evan Dandrea]

** Description changed:

  Watching GNetworkMonitor's network-changed signal causes constant DNS
  traffic.
  
- Unfortunately, we currently need this because checking NetworkManager's
- state for CONNECTED_GLOBAL is not enough to know whether we're really
- online since Ubuntu does not yet use the NetworkManager connectivity
- check [1].
+ Andy Whitcroft points out that the NETLINK_ROUTE socket set up by
+ GNetworkMonitor will fire events every time there 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.

  Unfortunately, we currently need an additional layer of connectivity
