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, 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. This option is required.

       -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 destination.

              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_RAWIO  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.

AVAILABILITY
       arping   is   part   of   iputils   package   and   the   latest   versions   are    available   in   source   form    at
