ARPING(8)              System Manager's Manual: iputils              ARPING(8)

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, 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:
              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.
