-
-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.

+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.

-- 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 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.
 
 Current maintainer:
+   David Schweikert <david@schweikert.ch>
 
-David Papp - david@remote.net 
+Website:
+   http://fping.org/
+
+Mailing-list:
+   https://groups.google.com/group/fping-users
 
 
-fping website:  http://www.fping.com
+Installation
+------------
+If you want to install fping from source, proceed as follows:
+
+1. Run ./configure with the correct arguments
+   (see: ./configure --help)
+
+2. Run make; make install
+
+3. Make fping either setuid, or, if under Linux:
+
+   sudo setcap cap_net_raw+ep fping
+
+4. Have a look at the fping(8) manual for usage help
+   (fping -h will also give a minimal help output)
 
 
+IPv6 support
+------------
+You can can compile fping with support for IPv6 addresses. A separate binary
+is used for that, called fping6. To build it, use ./configure --enable-ipv6
+(possibly combined with --enable-ipv4 to also build fping for IPv4). E.g.:
+
+  # ./configure --prefix=/usr/local --enable-ipv4 --enable-ipv6
+  # make
+  # make install
+  # sudo setcap cap_net_raw+ep /usr/local/bin/fping*

-Original README from 1992! 5 years ago? Time flies...
-
-        fping - A tool to quickly ping N number of hosts to determine
-        their reachability.
-
-             Roland J. Schemers III - Stanford University
-                   schemers@Stanford.EDU
-
-      fping is a ping(1) like program which uses the Internet Control
-      Message Protocol (ICMP) echo request to determine if a host is
-      up. fping is different from ping in that you can specify any
-      number of hosts on the command line, or specify a file containing
-      the lists of hosts to ping. Instead of trying one host until it
-      timeouts or replies, fping will send out a ping packet and move
-      on to the next host in a round-robin fashion. If a host replies,
-      it is noted and removed from the list of hosts to check. If a host
-      does not respond within a certain time limit and/or retry limit it 
-      will be considered unreachable. 
-
-Site
-      Stanford University has a large TCP/IP network with over 16,000 
-      assigned IP addresses and over 100 IP subnets.
-
-Problem and Issues
-
-      With a large a number of IP addresses in use, its becomes more and
-      more time consuming to check on which IP addresses are actively
-      in use, and which critical machines (routers, bridges, servers, etc)
-      are reachable. One example is we have a program which goes through
-      all of our routers arp caches looking for IP addresses that are in 
-      use. After finding a list of IP addresses that aren't in any arp
-      caches fping can then be used to see if these IP addresses really
-      aren't being used, or are just behind the routers. Checking 2500
-      hosts (99% of which are unreachable) via ping can take hours.
-       
-      fping was written to solve the problem of pinging N number of hosts
-      in an efficient manner. By sending out pings in a round-robin fashion
-      and checking on responses as they come in at random, a large number of 
-      hosts can be checked at once.
-
-      Unlike ping, fping is meant to be used in scripts and its
-      output is easy to parse.

+        fping - A tool to quickly ping N number of hosts to determine
+        their reachability.
+
+             Roland J. Schemers III - Stanford University
+                   schemers@Stanford.EDU
+
+      fping is a ping(1) like program which uses the Internet Control
+      Message Protocol (ICMP) echo request to determine if a host is
+      up. fping is different from ping in that you can specify any
+      number of hosts on the command line, or specify a file containing
+      the lists of hosts to ping. Instead of trying one host until it
+      timeouts or replies, fping will send out a ping packet and move
+      on to the next host in a round-robin fashion. If a host replies,
+      it is noted and removed from the list of hosts to check. If a host
+      does not respond within a certain time limit and/or retry limit it 
+      will be considered unreachable. 
+
+Site
+      Stanford University has a large TCP/IP network with over 16,000 
+      assigned IP addresses and over 100 IP subnets.
+
+Problem and Issues
+
+      With a large a number of IP addresses in use, its becomes more and
+      more time consuming to check on which IP addresses are actively
+      in use, and which critical machines (routers, bridges, servers, etc)
+      are reachable. One example is we have a program which goes through
+      all of our routers arp caches looking for IP addresses that are in 
+      use. After finding a list of IP addresses that aren't in any arp
+      caches fping can then be used to see if these IP addresses really
+      aren't being used, or are just behind the routers. Checking 2500
+      hosts (99% of which are unreachable) via ping can take hours.
+       
+      fping was written to solve the problem of pinging N number of hosts
+      in an efficient manner. By sending out pings in a round-robin fashion
+      and checking on responses as they come in at random, a large number of 
+      hosts can be checked at once.
+
+      Unlike ping, fping is meant to be used in scripts and its
+      output is easy to parse.

+=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. 
+
+=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>
+
+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. 
+
+=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. 
+
+=item B<-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. 
+
+=item B<-D>
+
+Add Unix timestamps in front of output lines generated with in looping or counting
+modes (B<-l>, B<-c>, or B<-C>).
+
+=item B<-e>
+
+Show elapsed (round-trip) time of packets. 
+
+=item B<-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 
+
+=item B<-g> I<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 
+
+=item B<-h>
+
+Print usage message.
+
+=item B<-i> I<n>
+
+The minimum amount of time (in milliseconds) between sending a ping packet
+to any target (default is 25). 
+
+=item B<-l>
+
+Loop sending packets to each target indefinitely. Can be interrupted with
+Ctrl-C; statistics about responses for each target are then displayed. 
+
+=item B<-m>
+
+Send pings to each of a target host's multiple interfaces.
+
+=item B<-n>
+
+Same as -d. 
+
+=item B<-p> <n>
+
+In looping or counting modes (B<-l>, B<-c>, or B<-C>), this parameter sets
+the time in milliseconds that B<fping> waits between successive packets to
+an individual target.  Default is 1000. 
+
+=item B<-q>
+
+Quiet. Don't show per-probe results, but only the final summary. Also don't
+show ICMP error messages.
+
+=item B<-Q> I<n>
+
+Like B<-q>, but show summary results every n seconds.
+
+=item B<-r> I<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. 
+
+=item B<-s>
+
+Print cumulative statistics upon exit. 
+
+=item B<-S> I<addr>
+
+Set source address. 
+
+=item B<-I> I<if>
+
+Set the interface (requires SO_BINDTODEVICE support) 
+
+=item B<-t> I<n>
+
+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. 
+
+=item B<-T> I<n>
+
+Ignored (for compatibility with fping 2.4). 
+
+=item B<-u>
+
+Show targets that are unreachable. 
+
+=item B<-O> I<n>
+
+Set the typ of service flag (TOS). I<n> can be either decimal or hexadecimal
+(0xh) format. 
+
+=item B<-v>
+
+Print B<fping> version information. 
+
+=item B<-H> I<n>
+
+Set the IP TTL field (time to live hops).

-.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
