This is how to re-create the issue: 1. Start pinging an IP where you get an ICMP error message from some other device (RFC792 lists errors). For instance: Destination IP is offline and the last-hop router reports message type "Destination Unreachable". I assume this would work for any ICMP error, though. 2. When the device comes back online, ping reports replies from the "other" device, when it should report replies from the device that is sending the "Echo Reply" messages. 3. If the ping is stopped and restarted after the device is up, it reports the correct IP address again. Other ping utilities do not exhibit this behavior. Example output (Destination that was pinged was 172.21.56.50, last hop router was 172.21.25.103): circle@circle:~$ /bin/ping 172.21.56.50 PING 172.21.56.50 (172.21.56.50) 56(84) bytes of data.
