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

\FC-A\F[]
    The same as \FC-U\F[], but ARP REPLY packets used instead of ARP REQUEST.

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

\FC\F[]Stop after sending count ARP REQUEST
    packets. With deadline [arping(8)] option, arping waits for count ARP REPLY packets, until the timeout expires.

\FC-D\F[]
    Duplicate address detection mode (DAD). See . Returns 0, if DAD succeeded i.e. no replies are received

\FC-f\F[]
    Finish after the first reply confirming that target is alive.

\FC\F[]Name of network device where to send ARP REQUEST packets.

\FC-h\F[]
    Print help page and exit.

\FC-q\F[]
    Quiet output. Nothing is displayed.

\FC\F[]IP source address to use in ARP packets.
    If this option is absent, source address is:

    •   In DAD mode (with option \FC-D\F[]) set to 0.0.0.0.

    •   In Unsolicited ARP mode (with options \FC-U\F[] or \FC-A\F[]) set to destination.

    •   Otherwise, it is calculated from routing tables.

\FC-U\F[]
    Unsolicited ARP mode to update neighbours' ARP caches. No replies are expected.

\FC-V\F[]
    Print version of the program and exit.

\FC\F[]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 [arping(8)] packet are sent, it waits either for deadline [arping(8)] expire or until count [arping(8)] probes are answered.

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.
