-	fixed bug in output of -C
-
-Wed Jan  8 11:18:37 1997  Roland Schemers  <schemers@stanford.edu>
-
-	* Created ChangeLog file. What follows was from the CHANGES file.
-
-* Revision 2.0  1994/10/31 21:26:23 morgan
-
-  Substantial rewrite, including new features:
-
-    support some traditional ping features:
-      loop mode
-      specify size of data packets
-      specify how many pings to send
-      show per-response data
-      interpret ICMPs other than ICMP Echo response
-
-  also
-
-    rewrote main loop completely
-    make timings in tenths of milliseconds
-    do exponential backoff on retries
-    port to more systems
-    add some debugging stuff
-    do better checking on whether received ICMP is for us
-
-* Revision 1.24  1993/12/10  23:11:39  schemers
-
-  commented out seteuid(getuid()) since it isn't needed
-
-* Revision 1.23  1993/12/10  18:33:41  schemers
-
-  Took out the -f option for non-root users. This can be enabled by
-  defining ENABLE_F_OPTION before compiling. There is a call to
-  access before opening the file, but there is a race condition.
-  Reading from stdin is much safer.
-
-
-* Revision 1.22  1993/11/16  19:49:24  schemers
-
-  Took out setuid(getuid()) and used access() system call to
-  check for access to the file specified with "-f".
- 
-* Revision 1.21  1993/07/20  18:08:19  schemers
-
-  commented out the test to make sure the ping packet came from the
-  same IP address as the one we sent to. This could cause problems on
-  multi-homed hosts.
-
-* Revision 1.20  1993/02/23  00:16:38  schemers
-
-fixed syntax error (should have compiled before checking in...)
-
-* Revision 1.19  1993/02/23  00:15:15  schemers
-
-turned off printing of "is alive" when -a is specified.
-
-* Revision 1.18  1992/07/28  15:16:44  schemers
-
-added a fflush(stdout) call before the summary is sent to stderr, so
-everything shows up in the right order.
-
-* Revision 1.17  1992/07/23  03:29:42  schemers
-* Revision 1.16  1992/07/22  19:24:37  schemers
-
-Fixed declaration of timeval_diff. Didn't notice the problem because
-I use 'cc' in stead of gcc under Ultrix. Time to switch? :-)
-
-Modified file reaing so it would skip blank lines or lines starting
-with a '#'. Now you can do something like:
-
-fping -ad < /etc/hosts
-
-* Revision 1.15  1992/07/21  17:07:18  schemers
-
-Put in sanity checks so only root can specify "dangerous" options.
-Changed usage to show switchs in alphabetical order.
-* Revision 1.14  1992/07/21  16:40:52  schemers
-* Revision 1.13  1992/07/17  21:02:17  schemers
-
-Changed the default timeout to 2500 msec, and retry to 3. This was
-due to suggestions from people with slow (WAN) networks. The default
-1 sec timeout was too fast.
-
-
-Added '-e' option for showing elapsed (round-trip) times on pakets, and
-modified the -s option to include min, max, and average round-trip times,
-and over all elapsed time.
-
-Modified action taken when a error is returned from sendto. The action
-taken now considers the host unreachable and prints the hostname 
-followed by the errno message. The program will not exit and will continue
-to try other hosts.
-
-* Revision 1.12  1992/07/17  16:38:54  schemers
-* Revision 1.11  1992/07/17  16:28:38  schemers
-
- move socket create call so I could do a setuid(getuid()) before the
- fopen call is made. Once the socket is created root privs aren't needed
- to send stuff out on it.
-
- moved num_timeout counter. It really was for debug purposes and didn't
- make sense to the general public :-) Now it is the number of timeouts
- (pings that didn't get received with the time limit).
-
-
-* Revision 1.10 1992/07/16  16:24:38  schemers
-* Revision 1.9  1992/07/16  16:00:04  schemers
-* Revision 1.8  1992/07/16  05:44:41  schemers
-
-Added _NO_PROTO stuff for older compilers, and _POSIX_SOURCE
-for unistd.h, and _POSIX_SOURCE for stdlib.h. Also added
-check for __cplusplus.
-
-Now compiles ok under Ultrix 3.1, and Sun4 using cc. Also compiled
-ok using g++ 2.2.2.
-
-Changed '-a' and '-u' flags to be mutually exclusive (makes sense, since
-specifiying both '-a' and '-u' is the same as not specifiying anything.
-Since '-a' and '-u' are mutually exclusive, these options now only print
-the hostname, and not the 'is alive' or 'is unreachable'  messages.
-This makes it much easier to do stuff like:
-
-#!/usr/local/bin/perl
-$hosts_to_backup=`cat /etc/hosts.backup|fping -a`;
-
-Since you don't have to strip off the 'is alive' messages.
-
-Changed usage to and stats to print to stderr instead of stdout.

+	fixed bug in output of -C
+
+Wed Jan  8 11:18:37 1997  Roland Schemers  <schemers@stanford.edu>
+
+	* Created ChangeLog file. What follows was from the CHANGES file.
+
+* Revision 2.0  1994/10/31 21:26:23 morgan
+
+  Substantial rewrite, including new features:
+
+    support some traditional ping features:
+      loop mode
+      specify size of data packets
+      specify how many pings to send
+      show per-response data
+      interpret ICMPs other than ICMP Echo response
+
+  also
+
+    rewrote main loop completely
+    make timings in tenths of milliseconds
+    do exponential backoff on retries
+    port to more systems
+    add some debugging stuff
+    do better checking on whether received ICMP is for us
+
+* Revision 1.24  1993/12/10  23:11:39  schemers
+
+  commented out seteuid(getuid()) since it isn't needed
+
+* Revision 1.23  1993/12/10  18:33:41  schemers
+
+  Took out the -f option for non-root users. This can be enabled by
+  defining ENABLE_F_OPTION before compiling. There is a call to
+  access before opening the file, but there is a race condition.
+  Reading from stdin is much safer.
+
+
+* Revision 1.22  1993/11/16  19:49:24  schemers
+
+  Took out setuid(getuid()) and used access() system call to
+  check for access to the file specified with "-f".
+ 
+* Revision 1.21  1993/07/20  18:08:19  schemers
+
+  commented out the test to make sure the ping packet came from the
+  same IP address as the one we sent to. This could cause problems on
+  multi-homed hosts.
+
+* Revision 1.20  1993/02/23  00:16:38  schemers
+
+fixed syntax error (should have compiled before checking in...)
+
+* Revision 1.19  1993/02/23  00:15:15  schemers
+
+turned off printing of "is alive" when -a is specified.
+
+* Revision 1.18  1992/07/28  15:16:44  schemers
+
+added a fflush(stdout) call before the summary is sent to stderr, so
+everything shows up in the right order.
+
+* Revision 1.17  1992/07/23  03:29:42  schemers
+* Revision 1.16  1992/07/22  19:24:37  schemers
+
+Fixed declaration of timeval_diff. Didn't notice the problem because
+I use 'cc' in stead of gcc under Ultrix. Time to switch? :-)
+
+Modified file reaing so it would skip blank lines or lines starting
+with a '#'. Now you can do something like:
+
+fping -ad < /etc/hosts
+
+* Revision 1.15  1992/07/21  17:07:18  schemers
+
+Put in sanity checks so only root can specify "dangerous" options.
+Changed usage to show switchs in alphabetical order.
+* Revision 1.14  1992/07/21  16:40:52  schemers
+* Revision 1.13  1992/07/17  21:02:17  schemers
+
+Changed the default timeout to 2500 msec, and retry to 3. This was
+due to suggestions from people with slow (WAN) networks. The default
+1 sec timeout was too fast.
+
+
+Added '-e' option for showing elapsed (round-trip) times on pakets, and
+modified the -s option to include min, max, and average round-trip times,
+and over all elapsed time.
+
+Modified action taken when a error is returned from sendto. The action
+taken now considers the host unreachable and prints the hostname 
+followed by the errno message. The program will not exit and will continue
+to try other hosts.
+
+* Revision 1.12  1992/07/17  16:38:54  schemers
+* Revision 1.11  1992/07/17  16:28:38  schemers
+
+ move socket create call so I could do a setuid(getuid()) before the
+ fopen call is made. Once the socket is created root privs aren't needed
+ to send stuff out on it.
+
+ moved num_timeout counter. It really was for debug purposes and didn't
+ make sense to the general public :-) Now it is the number of timeouts
+ (pings that didn't get received with the time limit).
+
+
+* Revision 1.10 1992/07/16  16:24:38  schemers
+* Revision 1.9  1992/07/16  16:00:04  schemers
+* Revision 1.8  1992/07/16  05:44:41  schemers
+
+Added _NO_PROTO stuff for older compilers, and _POSIX_SOURCE
+for unistd.h, and _POSIX_SOURCE for stdlib.h. Also added
+check for __cplusplus.
+
+Now compiles ok under Ultrix 3.1, and Sun4 using cc. Also compiled
+ok using g++ 2.2.2.
+
+Changed '-a' and '-u' flags to be mutually exclusive (makes sense, since
+specifiying both '-a' and '-u' is the same as not specifiying anything.
+Since '-a' and '-u' are mutually exclusive, these options now only print
+the hostname, and not the 'is alive' or 'is unreachable'  messages.
+This makes it much easier to do stuff like:
+
+#!/usr/local/bin/perl
+$hosts_to_backup=`cat /etc/hosts.backup|fping -a`;
+
+Since you don't have to strip off the 'is alive' messages.
+
+Changed usage to and stats to print to stderr instead of stdout.

-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
-   The file `configure.in' is used to create `configure' by a program
-called `autoconf'.  You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes a while.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
-     CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
-   If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

-Problems and Notes
-==================
-
-Apr 2001
-- Making fping requires 'm4' and 'autoheader'
-- fping is known not to build on Solaris. (Solaris lacks 'autoheader')
-- fping has been reported to bug out if a file contains more than 3600 addresses to scan.
-- If you are having problems compiling, try an earlier version (2.2b2 for example)

+# fping 3
+
+fping is a program to send ICMP echo probes to network hosts, similar to ping,
+but much better performing when pinging multiple hosts. fping has a long long
+story: Roland Schemers did publish a first version of it in 1992 and it has
+established itself since then as a standard tool.

+FPING(8)                                                              FPING(8)

+NAME
+       fping - send ICMP ECHO_REQUEST packets to network hosts
+
+SYNOPSIS
+       fping [ options ] [ systems... ] fping6 [ options ] [ systems... ]
+
+DESCRIPTION
+       fping is a program like ping 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 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 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, so its
+       output is designed to be easy to parse.
+
+       The binary named fping6 is the same as fping, except that it uses IPv6
+       addresses instead of IPv4.
+
+OPTIONS
+       -a   Show systems that are alive.
+
+       -A   Display targets by address rather than DNS name. Combined with -d,
+            the output will be both the ip and (if available) the hostname.
+
+       -b n Number of bytes of ping data to send.  The minimum size (normally
+            12) allows room for the data that 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 ping. Maximum is the theoretical maximum IP datagram size
+            (64K), though most systems limit this to a smaller, system-
+            dependent number.
+
+       -B n Backoff factor. In the default mode, 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 (-t) is multiplied on each successive request; it must be
+            entered as a floating-point number (x.y). The default is 1.5.
+
+       -c n Number of request packets to send to each target.  In this mode, a

+            format designed for automated response-time statistics gathering.
+            For example:
+
+             % fping -C 5 -q somehost

+
+            shows the response time in milliseconds for each of the five
+            requests, with the "-" indicating that no response was received to
+            the fourth request.
+
+       -d   Use DNS 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.
+
+       -D   Add Unix timestamps in front of output lines generated with in
+            looping or counting modes (-l, -c, or -C).
+
+       -e   Show elapsed (round-trip) time of packets.
+
+       -f   Read list of targets from a file.  This option can only be used by
+            the root user. Regular users should pipe in the file via stdin:
+
+             % fping < targets_file
+
+       -g addr/mask
+            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. If a network with netmask is given,
+            the network and broadcast addresses will be excluded. ex. To ping
+            the network 192.168.1.0/24, the specified command line could look

+
+             fping -g 192.168.1.0/24

+            or
+
+             fping -g 192.168.1.1 192.168.1.254
+
+       -h   Print usage message.
+
+       -i n The minimum amount of time (in milliseconds) between sending a

+=head1 NAME
+
+fping - send ICMP ECHO_REQUEST packets to network hosts
+
+=head1 SYNOPSIS
+
+B<fping> [ I<options> ] [ I<systems...> ] 
+B<fping6> [ I<options> ] [ I<systems...> ] 
+
+=head1 DESCRIPTION
+
+B<fping> is a program like B<ping> which uses the Internet Control Message
+Protocol (ICMP) echo request to determine if a target host is responding.
+B<fping> differs from B<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.
+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> ). Unlike B<ping>, B<fping> is meant to be used in scripts, so its
+output is designed to be easy to parse.
+
+The binary named B<fping6> is the same as B<fping>, except that it uses IPv6
+addresses instead of IPv4.
+
+=head1 OPTIONS
+
+=over 5
+
+=item B<-a>
+
+Show systems that are alive. 
+
+=item B<-A>
+
+Display targets by address rather than DNS name. Combined with -d, the output
+will be both the ip and (if available) the hostname.
+
+=item B<-b> I<n>
+
+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. 
+
+=item B<-B> I<n>
+
+Backoff factor. 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 (B<-t>) is multiplied on each
+successive request; it must be entered as a floating-point number (x.y). The
+default is 1.5. 
+
+=item B<-c> I<n>
+
+Number of request packets to send to each target.  In this mode, a line is
+displayed for each received response (this can suppressed with B<-q> or B<-Q>).
+Also, statistics about responses for each target are displayed when all
+requests have been sent (or when interrupted). 
+
+=item B<-C> I<n>
+
+Similar to B<-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
+C<-> indicating that no response was received to the fourth request.

+
+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. If

-.TH fping l
-.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 
-.MS ping 8
-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 DNS 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.  This option can only be used by the
-root user.  Regular users should pipe in the file via stdin:
-
-% 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)) {
-  # do it

+- Revision v2.4b2-to-IPv6
+   - Added IPv6 support.
+   - Added -I option for selecting source IPv4/IPv6 address.
+   - Makefile.in now generates a Makefile which will build both 
+     fping (IPv4) and fping6 (IPv6). Thus it makes an fping (IPv4 only)

+- Revision v2.4b1
+	- added -g option for generating IPs from a start to an end value
+		- two available options, generate IPs from start IP to end IP
+		  or from a passed netmask, such as 192.168.1.0/24
+
+Thu Feb 15 2001
+Jason Ewasiuk <jasone@remote.net>
+- Revision v2.3b1
+	- formatting changes to code layout (fping.c)
+	NOTE:  Best viewed with a tab stop of 4
+	- merged in changes from Debian c/o Herbert Xu
+	<herbert@gondor.apana.org.au>
+		- Compilation fix on alphas with glibc
+		- Alignment issues (note from JE:  in wait_for_reply())
+		- A typo with the time specified on the command line
+		(note from JE:  bug was using 10 instead of 100)
+		- Drop privileges after obtaining socket
+		(note from JE:  might be moot, since prog exits if
+		user is not root)
+	- touched all files in package to this date
+	- couple new #ifdefs added for future WIN32 support
+	(Haven't got to adding this yet, will take a lot of rewriting.)

+Fri Dec  8 10:33:13 2000  Roland Schemers  <schemers@stanford.edu>
+

+	fixed bug in output of -C
+
+Wed Jan  8 11:18:37 1997  Roland Schemers  <schemers@stanford.edu>
+
+	* Created ChangeLog file. What follows was from the CHANGES file.
+
+* Revision 2.0  1994/10/31 21:26:23 morgan
+
+  Substantial rewrite, including new features:
+
+    support some traditional ping features:
+      loop mode
+      specify size of data packets
+      specify how many pings to send
+      show per-response data
+      interpret ICMPs other than ICMP Echo response
+
+  also
+
+    rewrote main loop completely
+    make timings in tenths of milliseconds
+    do exponential backoff on retries
+    port to more systems
+    add some debugging stuff
+    do better checking on whether received ICMP is for us
+
+* Revision 1.24  1993/12/10  23:11:39  schemers
+
+  commented out seteuid(getuid()) since it isn't needed
+
+* Revision 1.23  1993/12/10  18:33:41  schemers
+
+  Took out the -f option for non-root users. This can be enabled by
+  defining ENABLE_F_OPTION before compiling. There is a call to
+  access before opening the file, but there is a race condition.
+  Reading from stdin is much safer.
+
+
+* Revision 1.22  1993/11/16  19:49:24  schemers
+
+  Took out setuid(getuid()) and used access() system call to
+  check for access to the file specified with "-f".
+ 
+* Revision 1.21  1993/07/20  18:08:19  schemers
+
+  commented out the test to make sure the ping packet came from the
+  same IP address as the one we sent to. This could cause problems on
+  multi-homed hosts.
+
+* Revision 1.20  1993/02/23  00:16:38  schemers
+
+fixed syntax error (should have compiled before checking in...)
+
+* Revision 1.19  1993/02/23  00:15:15  schemers
+
+turned off printing of "is alive" when -a is specified.
+
+* Revision 1.18  1992/07/28  15:16:44  schemers
+
+added a fflush(stdout) call before the summary is sent to stderr, so
+everything shows up in the right order.
+
+* Revision 1.17  1992/07/23  03:29:42  schemers
+* Revision 1.16  1992/07/22  19:24:37  schemers
+
+Fixed declaration of timeval_diff. Didn't notice the problem because
+I use 'cc' in stead of gcc under Ultrix. Time to switch? :-)
+
+Modified file reaing so it would skip blank lines or lines starting
+with a '#'. Now you can do something like:
+
+fping -ad < /etc/hosts
+
+* Revision 1.15  1992/07/21  17:07:18  schemers
+
+Put in sanity checks so only root can specify "dangerous" options.
+Changed usage to show switchs in alphabetical order.
+* Revision 1.14  1992/07/21  16:40:52  schemers
+* Revision 1.13  1992/07/17  21:02:17  schemers
+
+Changed the default timeout to 2500 msec, and retry to 3. This was
+due to suggestions from people with slow (WAN) networks. The default
+1 sec timeout was too fast.
+
+
+Added '-e' option for showing elapsed (round-trip) times on pakets, and
+modified the -s option to include min, max, and average round-trip times,
+and over all elapsed time.
+
+Modified action taken when a error is returned from sendto. The action
+taken now considers the host unreachable and prints the hostname 
+followed by the errno message. The program will not exit and will continue
+to try other hosts.
+
+* Revision 1.12  1992/07/17  16:38:54  schemers
+* Revision 1.11  1992/07/17  16:28:38  schemers
+
+ move socket create call so I could do a setuid(getuid()) before the
+ fopen call is made. Once the socket is created root privs aren't needed
+ to send stuff out on it.
+
+ moved num_timeout counter. It really was for debug purposes and didn't
+ make sense to the general public :-) Now it is the number of timeouts
+ (pings that didn't get received with the time limit).
+
+
+* Revision 1.10 1992/07/16  16:24:38  schemers
+* Revision 1.9  1992/07/16  16:00:04  schemers
+* Revision 1.8  1992/07/16  05:44:41  schemers
+
+Added _NO_PROTO stuff for older compilers, and _POSIX_SOURCE
+for unistd.h, and _POSIX_SOURCE for stdlib.h. Also added
+check for __cplusplus.
+
+Now compiles ok under Ultrix 3.1, and Sun4 using cc. Also compiled
+ok using g++ 2.2.2.
+
+Changed '-a' and '-u' flags to be mutually exclusive (makes sense, since
+specifiying both '-a' and '-u' is the same as not specifiying anything.
+Since '-a' and '-u' are mutually exclusive, these options now only print
+the hostname, and not the 'is alive' or 'is unreachable'  messages.
+This makes it much easier to do stuff like:
+
+#!/usr/local/bin/perl
+$hosts_to_backup=`cat /etc/hosts.backup|fping -a`;
+
+Since you don't have to strip off the 'is alive' messages.
+
+Changed usage to and stats to print to stderr instead of stdout.

+fping 3 README
+--------------
+
+fping is a program to send ICMP echo probes to network hosts, similar to ping,
+but much better performing when pinging multiple hosts. fping has a long long
+story: Roland Schemers did publish a first version of it in 1992 and it has
+established itself since then as a standard tool.
