server - Problems while switching IP and MAC adresses - Ask Ubuntu

i've got 2 ubuntu-servers, each of them 2 ethernet cards. i'm trying switch 1 other high availability purposes. unfortunately, when querying arp mac address of first card (eth0) , not 1 of second card (eth1) ip-address has been dynamically assigned. can do? example: server 1: eth0 mac: 00:11:11:11:11:11 ip: 192.168.0.1 eth1 mac: 02:33:33:33:33:33 ip: 192.168.0.3 server 2: eth0 mac: 00:22:22:22:22:22 ip: 192.168.0.2 eth1 down (goes mac , ip server1 eth1 when server1 goes down) when execute arp -a 192.168.0.3 command windows machine, result 00:11:11:11:11:11 (eth0) , not 02:33:33:33:33:33 (eth1) what you're trying not impossible, not optimal neither... back in xxth century, used exactly you're trying now, in xxist century, use bonding gives both reliability , higher throughput when both cards up. so forget 2 ip addresses on 2 nics, go 1 ip address on both nics , take advantage of double throughput! :-)
