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.
availability
arping is part of iputils package and the latest
versions are available in source form at
http://www.skbuff.net/iputils/iputils-current.tar.bz2.
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.
