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

expire or until
count
probes are answered.

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.
