Are you using fping instead of regular ping? It is a different package from
ping that needs to be installed separately. Here is an excerpt from its man
page:
fping is a like program which uses the Internet Control Message Proto-
col (ICMP) echo request to determine if a target host is
responding.
fping differs from ping in that you can specify any number of
targets
on the command line, or specify a file containing the lists of
targets
to ping. Instead of sending to one target until it times out
or
replies, fping will send out a ping packet and move on to the next
tar-
get in a round-robin fashion.
Good Luck,
Gregg.
