You are ignoring the server? Your client sends a DHCPDISCOVER -- for some reason it flips a bit in the client identifier, but that doesn't really matter, since it's just something the client and the server need to agree on -- and the server broadcasts DHCPOFFERS. What I'm not seeing here, are DHCPREQUESTs, which your client needs to send to accept an offer. Strangely, there are DHCPACKs, which suggests the server has seen a DHCPREQUEST. It is very interesting that in the FreeBSD case, the server seems to want to broadcast it's DHCPOFFER and in the OS X case, it unicasts it. - Philip -- Philip Paeps Please don't Cc me, I am philip@freebsd.org subscribed to the list.
