Expanding the list of channels only shows some of the channels, and it is apparent that TS did not fully connect. TeamSpeak almost immediately then times out of the server being joined. TS becomes unusable as it cannot join any servers.

I'll release dhcpcd-3.0.17 then, which should solve this once and for all :/ uberlord@gentoo.org 2007-04-14 08:00:36 0000 Fixed in dhcpcd-3.0.17 uberlord@gentoo.org 2007-04-14 09:46:46 0000 .
