Does anyone know how to use Ruby to grab a list of the MAC addresses of all the devices on the local network? Preferably as quick a response as possible.
Thanks!

Substitute your actual IP range for the X's
ping -c 2 x.x.x.255
And then parse the results of an
arp -a

Unfortunately this won't work very well cross-platform, don't suppose you know if Ruby has equivalent commands?

Ruby's ping implementation does not use ICMP and there is no built-in ARP library that I'm aware of, so probably not.

Shame - thanks!

All the currently common operating systems I can think of will have the 'ping' and 'arp' commands if they have an IP stack. The command parameters would be slightly different, however (e.g. in Linux 'ping -c 1 ...' sends only one packet, where the Windows equivalent would be 'ping -n 1 ...'; and with NIX the command 'arp' will show the whole table, whereas with Windows you need to do 'arp -a').
