Bug #301430 in netcfg Ubuntu: “ipv6 /etc/hosts missing localhost hostname”

Posting this for anyone else having odd network-related issues with Ubuntu Intrepid Ibex.

I’ve noticed since upgrading that my Gnome Desktop takes literally 3-4x as long to start, and was experiencing problems with ALSA shutdown on my home desktop machine. Sound Settings, Network Manager, and Google Desktop were taking an excessive amount of time to start. Also- all of my Internet apps were taking an excessively long time to start, including Firefox, Chrome, Thunderbird, and MS-Outlook (via Crossover). As it turns out- pretty much any app that can talk IPv6 is affected by this bug.

The fix is simple. Add “localhost” to the top of the IPv6 section of /etc/hosts so it looks like:

::1 localhost ip6-localhost ip6-loopback

Since doing this (and logging out/in again), it’s like I have a new computer. This is a really awful bug as anyone upgrading to Intrepid would be impacted by it, and it is difficult to discover WHY things are crawling along. Fortunately new installs will add this from the beginning, but upgrades missed it for some reason, and apparently some upgraded apps will search for an IPv6 localhost.
