Guys,

What would I use to get a list of hosts on the local subnet aside from
dumping
the forward zone in bind or doing a ping -c .1 subnet.1-254? I want to find
something I can call from a script to return the list to either a single
variable or an array.

I'm open to anything, but would prefer a BASH or c solution.


I use my Nexus One. Use to use my iPhone. Lots of apps for that.

When no tools at hand:
ping -c 2 -b <broadcast IP> (something like 192.168.1.255 - You need -b
option)
-c 2 sends just two pings. No need to get crazy.

then immediatly do

/sbin/arp -n

And you will have a list of hosts by IP.
