Hi there i had those problems too. It seems to work after i disables all iptables modules. I think this bug caused by wrong-not good iptables policy .
As I'm a regular desktop user, and i sit behind router I find it ok to remove iptables. rmmod iptable_filter rmmod x_tables rmmod ip_tables worked for me :) -- [karmic regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
