 ARP is address resolution protocol:   A TCP/IP protocol used to convert an IP address into a physical address, such as an Ethernet address.  A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the address in the request then replies with its physical hardware address. ARP is address resolution protocol:   A TCP/IP protocol used to convert an IP address into a physical address, such as an Ethernet address.  A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network.

 The second example we will look at is reusing the captured ARP from the example above.  You will notice that it said the ARP requests were being saved in "replay_arp-0219-123051.cap" So rather then waiting for a new ARP, we simply reuse the old ones with the "-r" parameter: The second example we will look at is reusing the captured ARP from the example above.  You will notice that it said the ARP requests were being saved in "replay_arp-0219-123051.cap" So rather then waiting for a new ARP, we simply reuse the old ones with the "-r" parameter:

 +Although not a direct troubleshooting tip for the arp request reinjection attack, if you are unable to get the attack to work or there are no arp request packets coming from the access point, there is an alternate attack you should consider:
