ARPING System Manager's Manual: iputils
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 suc-
ceeded 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.
