 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:
 
               · 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_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.
