Hi, > and selected em1 and gave it its IP parameters > (I used the same hostname macos.cmi.ua.ac.be, in the DNS servers here > macos.cmi.ua.ac.be is assigned to two IP addresses) First I doubt that this will work. You can assign several names to a single IP address in DNS, but you cannot assign several IP to the same name. > (After rebooting, em1 appears in the boot messages with the correct > Mac- and IP address.. ) > > But I get many messages: > Jan 13 11:05:25 macos kernel: arp: 143.129.XX.YY is on em0 but got reply > from 00:1b:21:UU:VV:WW on em1 > Jan 13 11:54.25 macos kernel: arp: 143.129.XX.YY is on em0 but got reply > from 03:ba:14:UU:VV:WW on em1 Let me guess, both NIC are connected to the same network? If so you cannot predict what interface will reply first, so you can send a packet through one interface and get a reply from the other interface. In standard operation, you don't want to have your two NICs connected to the same LAN with and IP in the same subnet. > Or do I need to 'deconfigure' em1? How can I do that? Edit /etc/rc.conf and remove all the lines that start with: ifconfig_em1 Olivier
