NAME

       arpsend - send ARP requests

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
              ARP reply was received

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).
