-.SH NAME
-fping \- send ICMP ECHO_REQUEST packets to network hosts
-.SH SYNOPSIS
-.B fping
-[ \fIoptions\fR ]
-[ \fIsystems...\fR ]
-
-.SH DESCRIPTION
-.NXR "fping command"
-.NXR "ICMP ECHO_REQUEST"
-
-
-.B fping
-is a
-.B ping
-like program which uses the Internet Control
-Message Protocol (ICMP) echo request to determine if a target host is
-responding.
-.B 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,
-.B fping
-will send out a ping packet and move
-on to the next target in a round-robin fashion.
-.PP
-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.
-.B fping
-also supports sending a specified number of pings to a target, or
-looping indefinitely (as in
-.B ping
-).
-.PP
-Unlike
-.B ping
-,
-.B fping
-is meant to be used in scripts, so its output is designed to be
-easy to parse.
-.SH OPTIONS
-.IP \fB-a\fR 5
-Show systems that are alive.
-.IP \fB-A\fR 5
-Display targets by address rather than DNS name.
-.IP \fB-b\fIn\fR 5
-Number of bytes of ping data to send. The minimum size (normally 12)
-allows room for the data that
-.B fping
-needs to do its work (sequence number, timestamp). The reported
-received data size includes the IP header (normally 20 bytes) and ICMP
-header (8 bytes), so the minimum total size is 40 bytes. Default is
-56, as in
-.B ping.
-Maximum is the theoretical maximum IP datagram size (64K), though most
-systems limit this to a smaller, system-dependent number.
-.IP \fB-B\fIn\fR 5
-In the default mode,
-.B fping
-sends several requests to a target before giving up, waiting longer for
-a reply on each successive request. This parameter is the value by
-which the wait time is multiplied on each successive request; it must
-be entered as a floating-point number (x.y). The default is 1.5.
-.IP \fB-c\fR 5
-Number of request packets to send to each target. In this mode, a
-line is displayed for each received response (this can suppressed with
--q or -Q). Also, statistics about responses for each target are displayed
-when all requests have been sent (or when interrupted).
-.IP \fB-C\fR 5
-Similar to -c, but the per-target statistics are displayed in a format
-designed for automated response-time statistics gathering. For
-example:
-
-% fping -C 5 -q somehost
-
-somehost : 91.7 37.0 29.2 - 36.8
-
-shows the response time in milliseconds for each of the five requests,
-with the "-" indicating that no response was received to the fourth
-request.
-.IP \fB-d\fR 5
-Use gethostbyaddr(3NSL) to lookup address of return ping packet. This allows you to give
-fping a list of IP addresses as input and print hostnames in the output.
-.IP \fB-e\fR 5
-Show elapsed (round-trip) time of packets.
-.IP \fB-f\fR 5
-Read list of targets from a file.
-
-% fping < targets_file
-
-.IP \fB-g\fR 5
-Generate a target list from a supplied IP netmask, or a starting and ending IP.
-Specify the netmask or start/end in the targets portion of the command line.
-
-ex. To ping the class C 192.168.1.x, the specified command line could look like either:
-
-fping -g 192.168.1.0/24
-
-or
-
-fping -g 192.168.1.0 192.168.1.255
-.IP \fB-h\fR 5
-Print usage message.
-.IP \fB-i\fIn\fR 5
-The minimum amount of time (in milliseconds) between sending a ping packet to any target (default is 25).
-.IP \fB-l\fR 5
-Loop sending packets to each target indefinitely. Can be interrupted
-with ctl-C; statistics about responses for each target are then displayed.
-.IP \fB-m\fR 5
-Send pings to each of a target host's multiple interfaces.
-.IP \fB-n\fR 5
-Same as -d.
-.IP \fB-p\fR 5
-In looping or counting modes (-l, -c, or -C), this parameter sets the
-time in milliseconds that
-.B fping
-waits between successive packets to an individual target. Default is
-1000.
-.IP \fB-q\fR 5
-Quiet. Don't show per-target results, just set final exit status.
-.IP \fB-Q\fIn\fR 5
-Like -q, but show summary results every n seconds.
-.IP \fB-r\fIn\fR 5
-Retry limit (default 3). This is the number of times an attempt at pinging
-a target will be made, not including the first try.
-.IP \fB-s\fR 5
-Print cumulative statistics upon exit.
-.IP \fB-t\fIn\fR 5
-Initial target timeout in milliseconds (default 500). In the default
-mode, this is the amount of time that
-.B fping
-waits for a response to its first request. Successive timeouts are
-multiplied by the backoff factor.
-.IP \fB-u\fR 5
-Show targets that are unreachable.
-.IP \fB-v\fR 5
-Print
-.B fping
-version information.
-
-.SH EXAMPLES
-The following perl script will check a list of hosts and send mail if
-any are unreachable. It uses the open2 function which allows a program
-to be opened for reading and writing. fping does not start pinging the
-list of systems until it reads EOF, which it gets after INPUT is closed.
-Sure the open2 usage is not needed in this example, but it's a good open2
-example none the less.
-.nf
-
-#!/usr/local/bin/perl
-require 'open2.pl';
-
-$MAILTO = "root";
-
-$pid = &open2("OUTPUT","INPUT","/usr/local/bin/fping -u");
-
-@check=("slapshot","foo","foobar");
-
-foreach(@check) { print INPUT "$_\\n"; }
-close(INPUT);
-@output=<OUTPUT>;
-
-if ($#output != -1) {
- chop($date=`date`);
- open(MAIL,"|mail -s 'unreachable systems' $MAILTO");
- print MAIL "\\nThe following systems are unreachable as of: $date\\n\\n";
- print MAIL @output;
- close MAIL;
-}
-
-.ni
-Another good example is when you want to perform an action only on hosts
-that are currently reachable.
-.nf
-
-#!/usr/local/bin/perl
-
-$hosts_to_backup = `cat /etc/hosts.backup | fping -a`;
-
-foreach $host (split(/\\n/,$hosts_to_backup)) {
