As far as I now ping is just telling that the machine is on or shut
down not if you can log on or not.
I think ethernet card is responding when the machine is on and the
system is down.
I always use first
ping ### -i 2
(wait for 2 second on local network) to see if that IP number is
available.
Then, if the machine is responding to ping I try ssh with a timeout
otherwise would hang for quiet a long time if its system is down.
With AppleScipt, I include the do shell script "ssh xxxxx" inside a
tell inside a "with timout of 2 seconds"
This is what I do to scan all possible IP number on a local network to
check which machine is on and then which machine is overloaded or not.

I think that "ping" is for that.
forgive a newbie question, but can you ping with knowing only the
Mac's name?
You can ping the broadcast address for a subnet, but all ping is
going to
tell you is that there's a functional NIC and just enough IP to
return a
PING. It's not going to tell you bubkis about the applications
running on
that box.
Well that would be sufficient for my purposes. The target machine
sometimes changes IP numbers, though the name of the machine doesn't
change. Knowing the IP number of my target would help eliminate one of
the hang-there-and-do-nothing parts of one of my scripts.
There is a crack in everything. That's how the light gets in.
