A Program to Ping Multiple Hostshttp://www.fping.org
FPing is a Ping-like program which uses the Internet Control Message
Protocol (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 a list of
targets to ping. Instead of sending pings to one target until it times
out or replies, FPing will send out a ping packet and move on to the
next target in a round-robin fashion.
In the default mode, if a target replies, it is noted and removed from
the list of targets to check; if a target does not respond within a
certain time limit and/or retry limit it is designated as unreachable.
FPing also supports sending a specified number of pings to a target, or
looping indefinitely (as in Ping ).
Unlike Ping, FPing is meant to be used in scripts. Its output is
designed to be easy to parse.
