VK:
Just to elaborate: on my unix box I'm running tcpdump:
/usr/sbin/tcpdump -n -s 1024 -i eth0 -e src 192.168.123.10
I then turn on my printer (which I know is going to
come up with the IP address 192.168.123.10 and a gateway IP
of 192.168.123.123). Results:
tcpdump: listening on eth0
22:04:16.627612 0:60:b0:73:63:a4 ff:ff:ff:ff:ff:ff 0806 60: arp who-has
192.168.123.10 tell 192.168.123.10
22:04:16.630692 0:60:b0:73:63:a4 ff:ff:ff:ff:ff:ff 0806 60: arp who-has
192.168.123.123 tell 192.168.123.10
This is within seconds of the printer turning on. So
the printer does two things: it sends a broadcast ARP's looking
to see if any devices have its intended IP address, and it
sends a broadcast looking for its gateway.
Kaboodle's sniffer thread should be able to detect
this. Any "ARP who-has" broadcasts to "ff:ff:ff:ff:ff:ff"
should be sniffed. The first field after the timestamp is
the MAC address of a device that should be associated with
the IP address in the last field.
