    Default Arpspoof help

    Hi,

    Just trying to get to grips with how arp spoofing works, and i have got a perfect setup going using ettercap to find hosts, select targets and do the arp poisoning then using wireshark to get the packets (i coudnt see the packets in ettercap graphical mode?)

    But ideally i would like to use the dsniff arpspoof program to do this, but it isnt working

    From a wireless linux laptop, intercepting traffic from 192.168.1.5, and traffic for that IP from the router 192.168.1.1:
    Code:
    arpspoof -i ath0 -t 192.168.1.5 192.168.1.1
    arpspoof: coudn't arp for host 192.168.1.5
    Think thats correct syntax, so i need to do the above twice, tell the router that im 192.168.1.5 and tell 192.168.1.5 that im the router. But the commands are failing.

    Both machines are on the same LAN & Subnet so i don't see why it isn't working, i can ARP spoof these IPs fine in ettercap.

    Thanks for any help

    For arp spoofing might wanna read up on it here:

    As for ettercap try this one:
    http://ettercap.sourceforge.net/forum/viewforum.php?f=8
    To be successful here you should read all of the following.

    Failure to do so will probably get your threads deleted or worse.
