NAME
       arping - send ARP REQUEST to a neighbour host

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


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

OPTIONS
       -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, arping waits for count  ARP  REPLY  packets,  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:

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

	      o In  Unsolicited ARP mode (with options -U or -A) set to desti-
		nation.

	      o 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.

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

AVAILABILITY
       arping  is  part of iputils package and the latest versions are	avail-
       able  in	 source	 form  at   http://www.skbuff.net/iputils/iputils-cur-
