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.

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
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).
-C n 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.
-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
like either:
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
ping packet to any target (default is 25).
-l Loop sending packets to each target indefinitely. Can be
interrupted with Ctrl-C; statistics about responses for each
target are then displayed.
-m Send pings to each of a target host's multiple interfaces.
-n Same as -d.
-p <n>
In looping or counting modes (-l, -c, or -C), this parameter sets
the time in milliseconds that fping waits between successive
packets to an individual target. Default is 1000.
-q Quiet. Don't show per-probe results, but only the final summary.
Also don't show ICMP error messages.
-Q n Like -q, but show summary results every n seconds.
-r n Retry limit (default 3). This is the number of times an attempt at
pinging a target will be made, not including the first try.
-R Instead of using all-zeros as the packet data, generate random
bytes. Use to defeat, e.g., link data compression.
-s Print cumulative statistics upon exit.
-S addr
Set source address.
-I if
Set the interface (requires SO_BINDTODEVICE support)
-t n Initial target timeout in milliseconds (default 500). In the
default mode, this is the amount of time that fping waits for a
response to its first request. Successive timeouts are multiplied
by the backoff factor specified with -B. Note that this option
has no effect looping or counting modes (-l, -c, or -C).
-T n Ignored (for compatibility with fping 2.4).
-u Show targets that are unreachable.
-O n Set the typ of service flag (TOS). n can be either decimal or
hexadecimal (0xh) format.
-v Print fping version information.
-H n Set the IP TTL field (time to live hops).
EXAMPLES
Generate ~1000 pings per second to a host until canceled, printing
statistics on the fly at one second intervals, and printing statistics
at the end:
# fping -s -l -i 1 -p 1 -T 1 -Q 1 127.0.0.1
Note that ping intervals less than 10ms can only be used as root.

DIAGNOSTICS
Exit status is 0 if all the hosts are reachable, 1 if some hosts were
unreachable, 2 if any IP addresses were not found, 3 for invalid
command line arguments, and 4 for a system call failure.
RESTRICTIONS
If certain options are used (i.e, a low value for -i and -t, and a high
value for -r) it is possible to flood the network. This program must be
installed as setuid root in order to open up a raw socket, or must be
run by root. In order to stop mere mortals from hosing the network,
normal users can't specify the following:
· -i n, where n < 10 msec
· -r n, where n > 20
· -t n, where n < 250 msec

---------------------------------------------------------------------------------
Wed Jan 16 2002
Jeroen Massar
- 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.
