Well, I'm running OpenBSD 3.2, and it's nearly a default install as of yet. The DHCP client I'm using is simply dhclient.

I didn't think that based on the nature of my question the errors mattered, but I'm getting two of them commonly.

dhclient: send_packet: Network is down
and
DHPACK from <DHCP server's address> rejected due to a bogus yiaddr of 0.0.0.0

When I took apart the DHCP discover packets, the only major difference between the ones accepted and the ones not accepted by their server was that the packs accepted was simple.

The accepted ones included Option 61: Client identifier
Hardware type: Ethernet
Client hardware address: <MAC address of network card>

If there's anything else that may be needed, let me know. Like I said, I think all I need to do is find the syntax for adding my client identifiers into the dhclient.conf file. As an added note, I don't understand why it would be saying that the network is down because TCPDUMP is still seeing all kinds of packets flying around the network.

Hope this helps
