For example, add MACADDR=00:01:02:03:04:05 To /etc/sysconfig/network-scripts/ifcfg-eth0 Don't remove the HWADDR line. Then do a "service network restart" or reboot. -- fedora-list mailing list <a href="mailto:fedora-list@redhat.com">fedora-list@redhat.com</a> To unsubscribe: <a href="https://www.redhat.com/mailman/listinfo/fedora-list">https://www.redhat.com/mailman/listinfo/fedora-list </a> </blockquote></div> -- =================== Nguyen Danh Hieu Physics Faculty Moscow State University
