snort has helped me get packet info and the MAC address for a LAN diskless boot client which turns out as both 01:00:5E:--:--:FB and 01:00:5E:--:--:16 So far the dhcp server only communicates to port 5353 of this diskless client, while the tftp server sends packets for boot file from port 67 to port 68 of the system machine. I have uncommented Code: mdns = yes line in the tftp server /etc/xinetd.conf file - so what about . . . Code: # bind = Any other ideas or experience with a multicast MAC NIC on the client for bootp ? Thanks for any suggestions or criticism.
