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 18:15:52.599957 0:80:c7:d3:b1:73 ff:ff:ff:ff:ff:ff 8863 60: 1109 0000 000e 0103 0006 0080 c7d3 b173 0101 0000 00b6 0000 2045 4f45 4344 4546 4545 4a45 4645 4745 4645 4f45 4345 18:15:53.601846 0:10:67:0:3c:ee 0:80:c7:d3:b1:73 8863 71: 1107 0000 0033 0103 0006 0080 c7d3 b173 0101 0000 0102 001d 3133 3034 3130 3439 3931 3833 3632 2d73 6d73 322d 746f 726f 6e74 6f36 3301 0100 00 18:15:53.604529 0:80:c7:d3:b1:73 0:10:67:0:3c:ee 8863 60: 1119 0000 000e 0103 0006 0080 c7d3 b173 0101 0000 ee00 ffff ffff ffff 0080 c7d3 b173 0800 4500 00e0 651f 0000 8011 18:15:54.628027 0:10:67:0:3c:ee 0:80:c7:d3:b1:73 8863 67: 1165 06b2 002f 0103 0006 0080 c7d3 b173 0101 0000 0102 001d 3133 3034 3130 3439 3931 3833 3632 2d73 6d73 322d 746f 726f 6e74 6f36 33 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. josh -- "To succeed in the world, it is not enough to be stupid, you must also be well-mannered" -- Voltaire To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
