This is a multi-part message in MIME format. --------------010705070407050807080507 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sorry for the cross-post, but this could be either lists problem. I have 2 boxes running 7-STABLE as of 20081130, both i386 SMP. One is running ISC DHCPD 3.0.x from recent ports, and the other dhclient from make world. The server is refusing to answer the DISCOVER request, as it thinks the IP checksum is wrong, which tcpdump also confirms. Other DHCP clients are working fine on this network, so I do not believe it to be the network, server or dhcpd. Server is running a 2 Port Intel card - em driver. Client is a Dell PE1750 with 2 onboard NIC's - bge driver. I have tried turning off both RXCSUM and TXCSUM on both the client and server machines with no luck. I also tried the second NIC on the server with the same result. This setup was working just a couple of weeks ago, and the only thing that has changed is updating the src for a make world. PXE booting this server does result in an IP being issued, so it is pointing towards something new/changed in 7-STABLE. I have attached a 3 packet dump of the DISCOVER requests. Can anybody shed some light on this for me?
