[afnog] Duplicates found Nagios

[Tarig Y. Adam]

Hi Richard

If i got you right (duplicate from monitored device). we experienced the same problem and finally we found out this device has problem with ARP. when we send ARP request to this device, it will answer with two responses with two different MAC addresses. We solve this by assigning static MAC address to the device on the monitor if they on same network or by the router faced directly to this device if they on different networks.

Hallo,

I have my nagios monitoring box, however, it sometimes shows duplicates found. What could probably cause that?
