arpsend - utility to send ARP requests.
arpsend < -U -i source_ip | -D-e target_ip [-e target_ip] ... >
[-c count] [-w timeout]
Utility arpsend sends ARP packets on device interface to detect
or update neighbours' ARP caches with a given IP.
Run utility with one of the following commands:
Send broadcast ARP request to detect neighbours with
target_ip. You have to specify target_ip (-e option).
Send broadcast ARP request to update neighbours' ARP caches with
source_ip. You have to specify source_ip (-i option).
- -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.
arpsend returns 0 upon successful execution. If something goes wrong, it
returns an appropriate error code.
- 1 EXC_USAGE
- 2 EXC_SYSTEM
- 3 EXC_RECV
ARP reply was received
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
Interface you use have to be arpable and not be loopback (i.e.
/sbin/ip link show interface should show neither NOARP
not LOOPBACK flags in interface parameters).
