A bit: # cat /etc/udev/rules.d/70-persistent-net.rules # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # net device () SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="02:c4:03:82:c1:5 3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # net device () SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="02:c3:04:01:77:c 3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" =========================================== So I can pull that eth1 line that got generated error and change the eth0 line? Well I did that, took the macaddr and hwaddr lines. restarted network and it was not finding eth0. And it added eth1 back into /etc/udev/rules.d/70-persistent-net.rules. I cleaned that up, and rebooted. During the boot, I see the message: Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. [FAILED] and once I get started, ifconfig reports eth1 again, and the eth1 line got added to rules. But the network IS working with addresses I want. But on eth1 with the errors about eth0. So there seems to be something before rules that is needed to be edited, or there is some limitation on my driver(s). _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
