There's a line in > /etc/conf.d/net that explains how to do this (with macchanger). No, I didn't change MAC by OS. My /etc/conf.d/net file: config_eth0=3D( "aa.bb.cc.dd netmask 255.255.255.224" ) routes_eth0=3D( "default via 1.2.3.4" ) config_eth1=3D( "10.11.1.203 netmask 255.255.255.0" ) Nothing that changes MAC addresses for the NICs... Maybe it's BIOS feature for failover.. It seems I need reboot server to check BIOS settings. --=20 Sergey
