The dhclient.conf file doesn't exist by default in more modern versions of CentOS. You'll need to create it in /etc/dhcp, or by putting the requested options in /etc/dhcp/dhclient.d For CentOS 7, it should be safe to use http://pkgs.fedoraproject.org/cgit/dhcp.git/plain/README.dhclient.d as guidelines should you choose the latter route. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77
