Thanks for everyone answered my question. The problem is solved by editing /etc/udev/rules.d/30-net_persistent_names.rules as Jan Engelhardt, John Andersen, Scott Newton suggested. Jan Engelhardt said I probably previously had PCI NIC. I am 100% sure it was on-board NIC. Benji Weber made good suggestion that scripts / applications should not assume first available ethernet interface is eth0. I agree on this point but at least two application assumed this: 1) vmplayer; 2) opensuse yast, in 10.0 version it assume eth0 is available made me impossible to dial PPP on a special ether card, but the problem is gone in 10.1 Thanks all again! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
