You have been subscribed to a public bug: Since NetworkManager uses dnsmasq to resolve its DNS names, it sometimes enables the system to use dnsmasq before the network connection has been successfully established. This causes dnsmasq to try and fail to resolve some hostnames, it then caches them to its negative DNS cache.
To prevent this from happening I had to add no-negcache to /etc/dnsmasq.d/network-manager Should this be the default? I don't think any endpoint user benefits from negative DNS cache, not even network admins as the DNS system is robust enough to handle those. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- NetworkManager uses dnsmasq with negative DNS cache enabled https://bugs.launchpad.net/bugs/1172467 You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
