Hi.
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.
