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:

              • 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. 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 recommended to be used as
       set-uid root, because it allows user to modify ARP caches of neighbour hosts.
