ARPING(8)                        iputils                       ARPING(8)

NAME

       arping - send ARP REQUEST to a neighbour host

SYNOPSIS

       arping [-AbDfhqUV] [-c count] [-w deadline] [-i interval]
              [-s source] [-I interface] {destination}

DESCRIPTION

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

       arping supports IPv4 addresses only. For IPv6, see ndisc6(8).

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:

               • 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. If any
           replies are received, exit with status 0, otherwise status 1.
           When combined with the count option, exit with status 0 if
           count replies are received before the deadline expiration,
           otherwise status 1.

       -i interval
           Specify an interval, in seconds, between packets.

AUTHOR

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

SECURITY

       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.

AVAILABILITY

       arping is part of iputils package.
