-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   --> See the README file for fping-specific 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.

+# 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.

+[1mNAME[0m
+       fping - send ICMP ECHO_REQUEST packets to network hosts
+
+[1mSYNOPSIS[0m
+       [1mfping [22m[ [4moptions[24m ] [ [4msystems...[24m ] [1mfping6 [22m[ [4moptions[24m ] [ [4msystems...[24m ]
+
+[1mDESCRIPTION[0m
+       [1mfping [22mis a program like [1mping [22mwhich uses the Internet Control Message
+       Protocol (ICMP) echo request to determine if a target host is
+       responding.  [1mfping [22mdiffers from [1mping [22min 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, [1mfping [22mwill 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. [1mfping [22malso supports sending a
+       specified number of pings to a target, or looping indefinitely (as in
+       [1mping [22m). Unlike [1mping[22m, [1mfping [22mis meant to be used in scripts, so its
+       output is designed to be easy to parse.
+
+       The binary named [1mfping6 [22mis the same as [1mfping[22m, except that it uses IPv6
+       addresses instead of IPv4.
+
+[1mOPTIONS[0m
+       [1m-a   [22mShow systems that are alive.
+
+       [1m-A   [22mDisplay targets by address rather than DNS name. Combined with -d,
+            the output will be both the ip and (if available) the hostname.
+
+       [1m-b [4m[22mn[24m Number of bytes of ping data to send.  The minimum size (normally
+            12) allows room for the data that [1mfping [22mneeds 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 [1mping[22m. Maximum is the theoretical maximum IP datagram size
+            (64K), though most systems limit this to a smaller, system-
+            dependent number.
+
+       [1m-B [4m[22mn[24m Backoff factor. In the default mode, [1mfping [22msends 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 ([1m-t[22m) is multiplied on each successive request; it must be
+            entered as a floating-point number (x.y). The default is 1.5.
+
+       [1m-c [4m[22mn[24m Number of request packets to send to each target.  In this mode, a
+            line is displayed for each received response (this can suppressed
+            with [1m-q [22mor [1m-Q[22m).  Also, statistics about responses for each target
+            are displayed when all requests have been sent (or when
+            interrupted).
+
+       [1m-C [4m[22mn[24m Similar to [1m-c[22m, 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.
+
+       [1m-d   [22mUse 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.
+
+       [1m-D   [22mAdd Unix timestamps in front of output lines generated with in
+            looping or counting modes ([1m-l[22m, [1m-c[22m, or [1m-C[22m).
+

+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.  [1mfping [22mdiffers from [1mping [22min that you can specify any number
+       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, [1mfping [22mwill send out a ping packet and move on to the
+       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. [1mfping [22malso supports sending a
+       limit it is designated as unreachable. fping also supports sending a
       specified number of pings to a target, or looping indefinitely (as in
-       [1mping [22m). Unlike [1mping[22m, [1mfping [22mis meant to be used in scripts, so its

            includes the IP header (normally 20 bytes) and ICMP header (8
            bytes), so the minimum total size is 40 bytes.  Default is 56, as

+- 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)
+     and an fping6 (IPv6 only).
+   - num_unreachable was counted twice when a sendto() generated errors.
+   - See http://unfix.org/projects/ipv6/ 
+
+Tue Mar 14 2001
+Jason Ewasiuk <jasone@remote.net>
+- 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>
+
+	* stop using sys_errlist and start using strerror
+	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.

+ * 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
+ * changed usage() to use fprintf(stderr,"...");
+ *
+ * Revision 1.9  1992/07/16  16:00:04  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.
+ *
+ * Revision 1.8  1992/07/16  05:44:41  schemers
+ * changed -a and -u to only show hostname in results. This is
+ * for easier parsing. Also added -v flag
+ *
+ * Revision 1.7  1992/07/14  18:45:23  schemers
+ * initialized last_time in add_host function
+ *
+ * Revision 1.6  1992/07/14  18:32:40  schemers
+ * changed select to use FD_ macros
+ *
+ * Revision 1.5  1992/07/14  17:21:22  schemers
+ * standardized exit status codes
+ *
+ * Revision 1.4  1992/06/26  15:25:35  schemers
+ * changed name from rrping to fping
+ *
+ * Revision 1.3  1992/06/24  15:39:32  schemers
+ * added -d option for unreachable systems
+ *
+ * Revision 1.2  1992/06/23  03:01:23  schemers
+ * misc fixes from R.L. "Bob" Morgan
+ *
+ * Revision 1.1  1992/06/19  18:23:52  schemers
