Same things here in italy. I've found the problem: the router assign a reserved address via dhcp to the eth0 interfaces. When you do pon dsl-provider, the pppd logic write a correct /etc/resolv.conf file, but after some little amount of time (the lease time of the dhcp server of the router) the reserved address are refreshed, and resolv.conf rewritten.
Solutions? None so good, if you can set the dhcp server of the router to assign correct dns servers, or assign static IP adress to your PC. I think that dhcp/pppd have to interact better, indeed... so i think that this is still a bug. -- DNS number changes to 10.0.0.138 after some time of pon dsl-provider and Firefox stop working https://launchpad.net/bugs/70156 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
