Some things to check:
RHEL6/CentOS6 likes to let NetworkMangler control interfaces even if the system is a server and running services like dhcpd. You may be getting a failure message since the interface isn't up when dhcpd gets started. I only find NetworkMangler useful on systems that regularly change connectivity like my laptop. I just find it gets in the way on stable, wired networks. The same problem can occur on VMs just because the virtual interface comes up more slowly the a "real" hardware device. That is, eth1 sn't there yet when dhcpd starts. If you specify the correct interface that matches the IP address you want DHCP services on in /etc/sysconfig/dhcpd you shouldn't need a dummy interface/network specification. I notice that you mention /etc/dhcpd.conf but the location of the configuration file moved to /etc/dhcp with RHEL6/CentOS6. Unless you edit the startup files, dhcpd will use the configuration file /etc/dhcp/dhcpd.conf Cheers, Dave _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
