More experiments, results and proposed solution: 1) On a system with
whoopsie running network-manager NOT running, but network interface initialized via /etc/network/interfaces dnsmask running with network-managers configuration for dnsmasq IPv6 aktivated I see the annoying repetive DNS-traffic for daisy.ubuntu.com. One or more packets per minute. This proves network-manager itself is not the bad guy! 2) Network-manager provides a configuration to dnsmask which disabled cache (--cache-size=0). Removing this option from dnsmasq configuration reduces traffic rate to 1 packet per 10 minutes. This corresponds to the lifetime for the DNS record of daisy.ubuntu.com which is set to 600 seconds. 3) Running network-manager again and dnsmasq started from network- manager, but with the modified configuration shows same result as #2. 4) HOWTO modify configuration for dnsmasq: Network-manager provides the option --cache-size=0 as argument on command line. This cannot be overriden by config-files, but you can use a wrapper script which is called by network-manager instead of real dnsmasq. The fake dnsmask purges the option --cache-size=0 and calls the real dnsmasq. I provide this wrapper script as attachment. Place it in /usr/local/sbin (this directory is searched before /usr/sbin), name it dnsmasq, set owner and group to root and set execute bits. Use at own risk. Enjoy! ** Attachment added: "wrapper script for dnsmasq, purges option --cache-size=0" https://bugs.launchpad.net/whoopsie/+bug/991481/+attachment/4276624/+files/dnsmasq -- 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.
