networking - Locating computer on subnet/network -

-

here situation: have special device can communicate via ethernet. it's connected computer via ethernet cable , problem these devices changed time time , have different ip addresses. start 192.168. , rest might different. device answers imcp (ping). right have list of ips , ping them find device. know there 2 devices on network (this special device , laptop).

so looking solution find computers on 192.168.255.255 subnet , according reconfigure interfaces, bring them down/up , after connect device. how have manually configure stuff.

ideas how locate computers under subnet? know can broadcast ping, like: ping 192.168.1.255 doesn't work 192.168.255.255

i use nmap, take time, like: nmap -n -sp 192.168.0.0/24

but have on subnet 192.168.255.255 understand.

i looking why how configure , find machines on small local network 2 machines.

thanks, -david

you try pinging global broadcast address - 255.255.255.255.
