I have a linux network device with only one interface. When I attempt to ping another network device in the same subnet on the same VLAN I get (DUP!) responses. I can see with tcpdump that the device is sending two ICMP ping requests at the same time with the same sequence number before receiving any replies. The network device that I'm pinging responds to both ICMP ping requests as well. The ARP cache has only one entry for the network device that I'm pinging. I can't think of any reason why it'd want to send two identical ping requests at a time. Anyone?
