I hope this isn't off topic here...
My network will contain several ELDK-based devices configured with dynamic
IP addresses (DHCP). I need a way for any Windows PC on the subnet to
locate the devices without prior knowledge of their IP address. I'm hoping
to find a peer-to-peer
solution that doesn't involve a third party (DNS) server.
Can anyone recommend a strategy for finding devices with dynamic IPs?
I'm using ELDK 3.1 on a custom MPC5200-based board.
Thanks,
Ed Jubenville

not sure if you can do a broadcast ping and look at the arp info on
windows..but if I were to do this in linux, I'd do something like the
following
ping -b 255.255.255.255
CTRL-C after a few seconds
then
arp

Assign names and use a name server?

To do somehting similar here, we use a scheme were the windows host
sends out a UDP broadcast message, and all the devices have daemon
running, listening to that broadcast, and sends back (via broadcast) a
response with the IP address and serial number embedded.
We use this to identify all running devices on the network.
This only works within the same subnet.
