According to http://kb.digium.com/entry/12/

The Iaxy will respond to pings on port 9999. You can ping your
broadcast IP on your network and listen with tcpdump on your
network on port 9999 which will show the Iaxy responding and what
IP address it is coming from.

Ex.
ping 192.168.1.255
tcpdump -i eth0 udp port 9999"

Before I get my karma whacked again, does this work for anybody?

1) Shouldn't "ping 192.168.1.255" be "ping -b 192.168.1.255"

2) Aren't pings ICMP and thus "invisible" when tcpdump is looking for UDP?

3) How do you set a "port" on an ICMP ping?

4) How do YOU find an Iaxy on your network?

Thanks in advance,

I haven't used any Iaxy but from the example it looks like once you ping the
ip of the Iaxy it will responde with a udp packet from port 9999
So you don't actually ping the 9999 port, but again as I said never used it
so I could be wrong

I was most easily able to find them by watching my DHCP server logs.

You're right about the -b switch to ping, that's required.
