NAME         top

       arping - send ARP REQUEST to a neighbour host

SYNOPSIS         top

       arping [-AbDfhqUV] [-c count] [-w deadline] [-s source]
              [-I interface] destination

DESCRIPTION         top

       Ping destination on device interface by ARP packets, using source
       address source.

OPTIONS         top

       -A
           The same as -U, but ARP REPLY packets used instead of ARP
           REQUEST.

       -b
           Send only MAC level broadcasts. Normally arping starts from
           sending broadcast, and switch to unicast after reply received.

       -c count
           Stop after sending count ARP REQUEST packets. With deadline
           option, instead wait for count ARP REPLY packets, or until the
           timeout expires.

       -D
           Duplicate address detection mode (DAD). See RFC2131, 4.4.1.
           Returns 0, if DAD succeeded i.e. no replies are received

       -f
           Finish after the first reply confirming that target is alive.

       -I interface
           Name of network device where to send ARP REQUEST packets.

       -h
           Print help page and exit.

       -q
           Quiet output. Nothing is displayed.

       -s source
           IP source address to use in ARP packets. If this option is
           absent, source address is:

               · In DAD mode (with option -D) set to 0.0.0.0.

               · In Unsolicited ARP mode (with options -U or -A) set to
               destination.

               · Otherwise, it is calculated from routing tables.

       -U
           Unsolicited ARP mode to update neighbours' ARP caches. No replies
           are expected.

       -V
           Print version of the program and exit.

       -w deadline
           Specify a timeout, in seconds, before arping exits regardless of
           how many packets have been sent or received. In this case arping
           does not stop after count packet are sent, it waits either for
           deadline expire or until count probes are answered.

       arping was written by Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>.

SECURITY         top

       arping requires CAP_NET_RAW capability to be executed. It is not
       recommended to be used as set-uid root, because it allows user to
       modify ARP caches of neighbour hosts.
