I have an update on this, and it gets really weird. (I finally got back to the odd network in question.) 1) My problem isn't limited to Cisco, as it turns out: the _only_ box on this net I can talk to is the FBSD-4.0-R server. That one can talk to the router (and everything else just fine, via it's xl - based PCI card). This server acts as a DHCP server, and gleefully assigns an address to my card. 2) This card has a different MAC address, depending on which OS booted. Win98 00:e0:98:77:1a:b2 FBSD-4.0-R 01:d4:ff:03:00:20 3) I've pawed though the CIS of this card, and nothing leaps out at me. 4) There does not seem to be a way to manually set the MAC address of this card via FreeBSD. 5) I've pawed trough a couple of example 'ether 0xNNN' settings using examples from pccard.conf. This causes a wrong MAC address to be generated. Oddly, irrespective of the invented MAC address, the other FSBD box can stull talk to it. 6) I pawed through 'pccardc rdattr 0 0 1000', and could not find even a subset of the Win98-flavored MAC address in there (no two adjoining octects). I noticed that the pccard.conf entry for 'Telecom Device SuperSocket RE450T' had commented out entries like # ether 0x110 00:e0:98 # ether 0xff0 00:e0:98 Note: these three octets just to happen to match the Win98-flavored MAC address. Conicidence? I note this format of the 'ether' directive is no longer supported... I've saved raw tcpdumps of ping efforts via both addresses; I can provide if anyone is willing to poke at them. -- Brian 'you Bastard' Reichert reichert@numachi.com 37 Crystal Ave. #303 Daytime number: (781) 273-4100 x161 Derry NH 03038-1713 USA Intel architecture: the left-hand path To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
