Arp-request sniffing

What? Packet injection as in spoofing? Arping is a method of faking a response as to which machine owns an IP address. It's commonly used to create a "man in the middle" type of security nightmare. If this is what you're planning to do, please turn yourself in to the nearest federal anti-terrorism agency for re-education in proper use of internet protocols.

First, check if ARP decoding is enabled. Analyze -> Enabled Protocols -> ARP

You can generate an ARP request by pinging a new IP address on your LAN. It doesn't have to be a real device, just one that's not in the current arp cache: arp -a Yep. It works. Just ping any IP non-existant address in your Class C IP LAN block.

Hi all,

Ive been looking into some packet injection techniques and have read

that the best packets to inject into a network to increase traffic is

arp-requests.I have so far built up a 100Mb file of traffic and on

filtering for arp-requests with ethereal there isnt a single

arp-request packet.Is this typical? and can i somehow force arp-request

by maybe forcing dis-associations on the network?

Regards
