Now I cant even get a response from the server with just a simple PADI (with
no Host-Uniq tag). I've even powered up/down the modem. Swapping ethernet
cards is not an option, seeing as one machine is a laptop.
(this is odd, since I could send stuff from 2 different MAC addresses before).
Anyways, I sniffed the windows client making a connection. The results are
*very* wierd:
cerebus:~# tcpdump -i de1 -nev -s 256 ether proto 0x8863
tcpdump: listening on de1

Notice how it *is* using the Host-Uniq tag, and jamming the MAC address of the
ethernet card in. What I dont understand is all the garbage after the
Service-Name tag. Perhaps the windows client isnt nulling out a buffer
somewhere?
(another data-point, probably unrelated: I just noticed that I'm getting a
*completely* different range of IPs today than I did Friday night. I'm
wondering if when they made that change, that they also mucked around with the
SMS)
I did notice some if_ethersubr.c and ng_pppoe.c changes hit the tree, but I
havent gotten them yet. I'll see if I can do some more testing later this
evening.
