I had the need to add another IP address in the same subnet as the existing IP on em0, a virtual IP (em0:0?). I try to add an IP to the em0 and it gives me an error, see below, but seems to work fine on em1: esmtp# ifconfig em1 alias 66.129.101.220 255.255.255.248 esmtp# ifconfig -a em0: flags=8843 mtu 1500 options=3 inet 66.129.101.198 netmask 0xfffffff0 broadcast 66.129.101.207 inet6 fe80::230:48ff:fe29:847c%em0 prefixlen 64 scopeid 0x1 ether 00:30:48:29:84:7c media: Ethernet autoselect (100baseTX ) status: active em1: flags=8843 mtu 1500 options=3 inet 66.129.101.219 netmask 0xfffffff8 broadcast 66.129.101.223 inet6 fe80::230:48ff:fe29:847d%em1 prefixlen 64 scopeid 0x2 inet 66.129.101.220 netmask 0xff000000 broadcast 255.255.255.248 ether 00:30:48:29:84:7d media: Ethernet autoselect status: no carrier lo0: flags=8049 mtu 16384 inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 esmtp# ifconfig em1 alias 66.129.101.195 255.255.255.240 ifconfig: ioctl (SIOCAIFADDR): File exists Afterwards, now I am getting this message in the syslog similar to the others I originally posted: Mar 10 19:39:24 esmtp kernel: arp: 66.129.101.198 is on lo0 but got reply from 00:30:48:29:84:7c on em1 Can anyone help me understand what I'm doing wrong? -- Robert
