send ARP REQUEST to a neighbour host
' arping 'u arping [ -AbDfhqUV] [ -c count ][ -w deadline ][ -s source ][ -I interface ] destination
Ping destination on device interface by ARP packets, using source address source .
-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, instead wait for count ARP REPLY packets, or 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 destination .
Otherwise, it is calculated from routing tables .
-U Unsolicited ARP mode to update neighbours (Aq 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 .
arping requires CAP_NET_RAW 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 .
arping is part of iputils package .
