Comment 19 for bug 991481

I did some experiments on an Ubuntu GNOME 14.04 LTS desktop standard installation. There are 4 (!) components involved in this annoying traffic:

whoopsie
network manager
dnsmasq (started by network manager)
IPv6

The repeated DNS-requests for daisy.ubuntu.com stop when de-activating anyone of these! You (as root) may use these recipes as workarounds:
Workaround #1: De-activate whoopsie:
#initctl stop whoopsie
#echo 'manual' > /etc/init/whoopsie.override

Or workaround #2: De-activate Network Manager:
#initctl stop network-manager
#echo 'manual' > /etc/init/network-manager.override
- Bring up network interface through config lines in file /etc/network/interfaces, e.g.
  iface eth0 inet dhcp
  auto eth0
#ifup eth0

Or workaround #3: Disable dnsmasq
- Edit file /etc/NetworkManager/NetworkManager.conf and change line with
  dns=dnsmasq
to
  #dns=dnsmasq
- Restart Network Manager:
# initctl restart network-manager

Or workaround #4: Disable IPv6:
#sysctl -w net/ipv6/conf/all/disable_ipv6=1
#echo 'net/ipv6/conf/all/disable_ipv6=1' >/etc/sysctl.d/10-ipv6-off
