These establish a correspondence between the interfaces and the MAC addresses of the NICs. And ifcfg-ethX sets up a correspondence between MAC addresses and IP addresses of the NICs, in my case eth1 -> 192.168.2.2 . It would be possible to deduce from this that eth1 corresponds to the subnet 192.168.2.0 . But dhcpd does not appear to make this deduction. If I might ask, are you running dhcpd under CentOS-6 ? Is anybody running dhcpd under CentOS-6 ? If so, I would be very interested to see your dhcpd.conf and ifcfg-ethX . I should say that dhcpd ran (and is running) perfectly under CentOS-5.6 , but not under CentOS-6. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
