Fping is a simple ping program, intended to be used instead of the
standard ping program that comes with windows. It was first made
to ping faster than once every second. Options have been added since
then and fping is now a very handy tool (at least I think it is).
PLATFORMS:
Windows 95, 98, NT 4.0, 2000, ME and XP
---------------------------------------------------------------------------------
Ping is one of the most useful network debugging tools available. The first ping
program was written by Mike Muuss in December 1983 for use on Unix machines. Muuss
named his program after the sonar sounds used for echolocation by submarines,
although some say ping stands for "Packet InterNet Grouper". Ping sends a small
packet of information containing an ICMP ECHO_REQUEST to a specified computer,
which then sends an ECHO_REPLY packet in return. The ping program then evaluates
this reply, and a report is shown. You can check several things with the ping
program: can you reach another computer, how long does it take to bounce a packet
off of another site, ... You can ping either a domain name, or an IP address.
Functionality to show domain names when using IP addresses is supported. Even
routing options are available, alas only 9 routes can be shown due to the
structure of the IP header (RFC 792). Why did I write my own ping program?
There are two main reasons: a) It wanted to know how the ping program worked. I
found it really intriguing and was very curious and b) There was a need for a
better ping program here at the lab where I work.
Usage:
fping
[-n count] [-h TTL] [-v TOS] [-r routes] [-a] [-f] [-b(-)] [-i]
[-l] [-T] [-d ping_data] [-H filename]
Options:
-s : data_size in bytes up to 65500
-S : size sweep. Ping with size1, size1 + 1, ..., size 2 datalength
-c : continuous ping (higher priority than -n)
to see statistics and continue - type Control-Break;
to stop - type Control-C.
-t : time between 2 pings in ms up to 5000
-w : timeout in ms to wait for each reply
-n : number of echo requests to send
-h : number of hops (TTL: 1 to 128)
-v : Type Of Service (0 to 255)
-r : record route (1 to 9 routes)
-a : resolve addresses to hostnames
-f : set Don't Fragment flag in packet
-b : beep on every successful reply (- to beep on timeout)
-i : use ICMP dll instead of raw socket (disables -r)
-l : limit the output to ping results and errors
-T : print timestamp with each reply
-d : ping with specified data
-H : get hosts from filename (comma delimited, filename with full path)
fping uses raw sockets. This can be a problem for NT / 2000 system
users without administrator rights. Raw socket creation will fail
due to a silly and useless socket protection. Fping will switch
to the ICMP dll if this happens (to ping the micro$oft way). To
disable this protection (and take full advantage of fping) you can
do the following:
a) NT4 users should change / add the following registry variable
and set its value to DWORD 1:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Afd\Parameters\DisableRawSecurity
b) 2000 users should set the following registry variable to DWORD 1
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\AllowUserRawAccess
after you change the registry, you will need to reboot.
You can also run the reg file in accordance with your os.
Return Values:
Reply: 0
Reply timed out: 1
Host not found: 2
Packet size exceeds MTU: 3
Too few bytes: 4
Non-echo type: 5
