       arping - sends arp and/or ip pings to a given host


       arping  [-abdDeFhpqrRd0uv]  [-S  host/ip] [-T host/ip] [-s MAC]    [-t MAC] [-c count] [-i
       interface] [ -w us ] <host | -B>

       arping --help


       The arping utility sends ARP and/or ICMP requests to the specified host and  displays  the
       replies. The host may be specified by its hostname, its IP address, or its MAC address.

       One request is sent each second.

       When  pinging  an  IP  an ARP who-has query is sent. When pinging a MAC address a directed
       broadcast ICMP Echo request is sent. For more technical explaination and an FAQ,  see  the
       README file.

       Note on timing

       ARP  packets  are  usually  replied to (on a LAN) so fast that the OS task scheduler can't
       keep up to get exact enough timing.  On an idle system the roundtrip times will be  pretty
       much accurate, but with more load the timing gets less exact.

       To get more exact timing on a non-idle system, re-nice arping to -15 or so.

       # nice -n -15 arping foobar

       This  is  not just an issue with arping, it is with normal ping also (at least it is on my
       system). But it doesn't show up as much with ping since arping packets (when  pinging  IP)
       doesn't traverse the IP stack when received and are therefore replied to faster.


       --help Show extended help. Not quite as extensive as this manpage, but more than -h.

       -0     Use  this  option to ping with source IP address Use this when you haven't
              configured your interface yet.  Note that this may  get  the  MAC-ping  unanswered.
              This is an alias for -S

       -a     Audible ping.

       -A     Only  count addresses matching requested address (This *WILL* break most things you
              do. Only useful if you are arpinging many hosts at once. See for
              an example).

       -b     Like  -0 but source broadcast source address (  Note that this may
              get the arping unanswered since it's not normal behavior for a host.

       -B     Use instead of host if you want to address

       -c count
              Only send count requests.

       -d     Find duplicate replies. Exit with 1 if there are answers  from  two  different  MAC

       -D     Display answers as dots and missing packets as exclamation points.  Like flood ping
              on a Cisco.

       -e     Like -a but beep when there is no reply.

       -F     Don't try to be smart about the interface name. Even if this switch is  not  given,
              -i disables this smartness.

       -h     Displays a help message and exits.

       -i interface
              Don't guess, use the specified interface.

       -p     Turn  on promiscious mode on interface, use this if you don't "own" the MAC address
              you are using.

       -q     Does not display messages, except error messages.

       -r     Raw output: only the MAC/IP address is displayed for each reply.

       -R     Raw output: Like -r but shows "the other one", can be combined with -r.

       -s MAC Set source MAC address. You may need to use -p with this.

       -S IP  Like -b and -0 but with set source address.  Note that  this  may  get  the  arping
              unanswered  if  the target does not have routing to the IP. If you don't own the IP
              you are using, you may need to turn on promiscious mode on the interface (with -p).
              With  this switch you can find out what IP-address a host has without taking an IP-
              address yourself.

       -t MAC Set target MAC address to use when pinging IP address.

       -T IP  Use -T as target address when pinging MACs that won't respond to a  broadcast  ping
              but perhaps to a directed broadcast.

              Example:                                                                  To  check
              the address of MAC-A, use knowledge of MAC-B and IP-B.

              $ arping -S <IP-B> -s <MAC-B> -p <MAC-A>

       -u     Show index=received/sent instead of just index=received when pinging MACs.

       -v     Verbose output. Use twice for more messages.

       -w     Time to wait between pings, in microseconds.

       You  have  to  use  -B  instead  of  arpinging,  and  -b  instead  of  -S This is libnets fault.
