Well, In fact I have had one totally unknown entry in /etc/iftab with line: eth0 mac {here totally random MAC} and where it came from I don't know.
What have helped me was removing/commenting this entry. After this simple step everything goes smoothly (at least with NICs, I have another problem with no sound which have been working on Dapper Beta 1 but not with Final - but it's a different story). [cite]In Ubuntu the /etc/iftab file is generated by the installer and used by udev[/cite] I guess it's better to put those two lines with eth0, eth1 in /etc/iftab for future upgrades. Thanks for explanations. -- NIC names - confusion https://launchpad.net/bugs/49121 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
