Looks like you have 2 ethernet interfaces/hosts which claim to be 134.173.66.250. ARP = Address Resolution Protocol, which runs this way: Hosts wants to contact 134.173.66.250, but don't know the MAC address, this host shouts onto the Ethernet: "Hello, is here someone with the IP number 134.173.66.250". An ARP server or the hosts with this IP number should answer: "Yes, I have MAC address aa:00:04:00:bb:06" Ulf. -- Ulf Zimmermann, NCD Software, 101 Rowland Way, Suite 300, Novato, CA 94945 phone: 415-899-7941, email: ulf@z-code.ncd.com, phone-home: 510-865-0204 ====================================== FreeBSD 2.1.0 is available now! -------------------------------------- FreeBSD: Turning PCs into Workstations ======================================
