IIRC, 98 had a hacked down version of the TCP/IP stack opposed to the normal unix stack. All though I don't think this would be a issue, as 98 boxes would not be able to use any type of switch if the TCP/IP stack did not have some type of MAC header in it. Clear your arp table and look to see if you get an arp address for the 98 boxes. You might find that you have a typo in the address, or pull the MAC right off the card it self. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
