| Hi
| I'm trying to get arp cache poisoning working on my wireless network.
| The setup is an AP with IP 192.168.0.100, a client with IP .55 and an
| attacker with IP .56. All devices can ping each other and looking at
| the arp table shows that they all know the MAC addresses of the
| others.
|
| I'm trying to use arpspoof to do ARP spoofing against the AP.
|
| On the attacker machine I've used the command:
|
| arpspoof -i ath0 -t 192.168.0.55 192.168.0.100
|
| but get the response
|
| "arpspoof: couldn't arp for the host 192.168.0.55"
|
| If I try the attack the other way so targetting the AP it still fails.
|
| Looking at the FAQ on monkey.org it says that this error is because
| the machines must be on the same subnet but they are in this
| situation, aren't they?
|
| If not, what is the best way to poison a wireless network?

Are you running arpspoof with root privilege?
Have you checked if iptables is stoped?
