SYNOPSIS
arpsend -D -e target_ip [ -e target_ip ...] [-c count] [-w timeout] interface
arpsend -U -i source_ip [-c count] [-w timeout] interface
DESCRIPTION
Utility arpsend sends ARP packets on device interface to detect or update neighbours' ARP caches with a given IP.
COMMANDS
Run utility with one of the following commands:
-D Send broadcast ARP request to detect neighbours with target_ip. You have to specify target_ip (-e option).
-U Send broadcast ARP request to update neighbours' ARP caches with source_ip. You have to specify source_ip (-i option).
OPTIONS -c count
Number of packets to send. Default is infinity.
-w interval
Interval between packets, in seconds. Default is 1 second.
-i source_ip_address
Set source IP address field in ARP packet.
-e target_ip_address
Set target IP address field in ARP packet. Note that you can specify -e option multiple times to detect many IP addresses in one
utility call.
EXIT STATUS
arpsend returns 0 upon successful execution. If something goes wrong, it returns an appropriate error code.
1 EXC_USAGE
Usage error
2 EXC_SYSTEM
System error
3 EXC_RECV

EXAMPLES
To send request on interface eth0 to detect any neighbour computers with IP 192.168.10.200:
arpsend -D -e 192.168.10.200 eth0
To send request on interface eth0 to update neighbours' ARP caches with IP 192.168.10.200:
arpsend -U -i 192.168.10.200 eth0
NOTES
Interface you use have to be arpable and not be loopback (i.e. /sbin/ip link show interface should show neither NOARP nor LOOPBACK flags
in interface parameters).
