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.

-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 desti‐
nation.

· 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_RAW capability to be executed. It is not recom‐
mended to be used as set-uid root, because it allows user to modify ARP
caches of neighbour hosts.

AVAILABILITY
arping is part of iputils package and the latest versions are avail‐
able in source form at http://www.skbuff.net/iputils/iputils-cur‐
rent.tar.bz2.
