IMO one possibility is deactivate interfaces, by rmmod unload its drivers, change /etc/udev/rules.d/NN-net.rules and modprobe/insmod drivers again (and then activate network). udev daemon should create network names with new ones. Another way could be using 'ifrename' utility from 'wireless-tools' package: 'ifrename -i OldInterfaceName -n NewInterfaceName' (network perhaps should be down too and it seems as ifrename requires '/etc/iftab' file (which may be empty, 'touch /etc/iftab')) FH -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
