This is a good question that I've recently been fighting at one of my sites.
The obsoleted-by-the-manufacturer-5-years-ago router, HP, is a primitive, but reliable device without many bells and whistles. Recently, on it's logs, I've been getting some unusual 'ARP squeals', as well as the troublesome request below. About all the log reveals is that it happened. If I could get a MAC address, I could at the very least figure what the darn thing is --- at this point I'm thinking printer with that 0.0.0.0 source. The other out-of-range ARP complaint is an occasional foreign IP address; again I need to pick up on that MAC. Of course, all this happens intermittently, so it's hard to catch 'in the act'. I fiddled with the Cisco 2900XL system message logs a bit, but don't have a syslog server at that site (yet --- Kiwi?), so I haven't got a hit (clue) on who the culprit(s) might be. Maybe I just don't know how yet; maybe I need that syslog system; maybe I should break out the Fluke or Sniffer. Sure seems like I could get those MAC addresses direct from the switch, somehow, though. Sooo, I await with great curiosity on the solution to this one.... Best, G.
