arping


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  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

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