I read the man dhclient.conf(5) and paid special attention to the part about prepend domain-name-servers. It does not say anything about passing the dns info dhcp client puts into resolv.conf onto the dhcpd.conf option domain-name-servers statement. I don't think you understood the original question.

Write a script to updated the dhcpd.conf file when resolv.conf changes. dhclient allows you to create hooks that automagically run a script of your choosing when a new lease is obtained. Or you could search the list archives for when this exact question was asked a few weeks ago. -- Bill Moran Collaborative Fusion Inc. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
