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 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/991481 Title: Constant dns traffic for daisy.ubuntu.com Status in Ubuntu error tracker client (whoopsie): Confirmed Status in glib2.0 package in Ubuntu: Invalid Status in network-manager package in Ubuntu: In Progress Status in whoopsie package in Ubuntu: Triaged 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. 1: http://bazaar.launchpad.net/~daisy- pluckers/whoopsie/trunk/view/head:/src/connectivity.c#L326 Original report follows: Every few seconds, I see a dns query for daisy.ubuntu.com. After removing whoopsie, the traffic goes away.
