Charles, I've got some experience with the X520 cards under various flavors of Linux. I've always had good luck. Although, they do require a bit more care and feeding than a Copper e1000. Can you be a bit more specific about what you're seeing? The other thing I'll throw out there: Do you have vlan tags set on these packets? If so, you need to add the "vlan" option to tcpdump. So, on mine: tcpdump -s 0 -w outfile.pcap -C 500 -i eth4 vlan Keep us posted. MJ - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
