[Arpspoof Disconnected Host]

You are arp attacking the router and another machine on the network though, right, and not yourself?

I ran the arp commands from a different system, Ubuntu at 192.168.0.5.

bringing down and up the NIC on the victim machine, and a few minutes for the router to update its arp table

By the way how do you do it in Windows 7? I tried

ipconfig /release

ipconfig /renew

and it didn't help. I'm sure I had waited more than a few minutes. Only the restart helped.

Thanks for the useful info.

By the way, you use the same subnet/netowrk as darren does at home? 10.13.37.0/24 ??

Sorry, I should have been more clear about it. I just used the above commands as an example from the video. My actual IP addresses were:

arpspoof -t 192.168.1.1 192.168.1.4

arpspoof -t 192.168.1.4 192.168.1.1

The Win7 host (192.168.1.4) is connected to a NetGear router. It worked for a little while after I ran the arpspoof commands from Ubuntu 11.10 but then lost the network.

Thanks.

I tried to use arpspoof as presented in the following episode:

http://hak5.org/hack/arp-spoofing-with-dsniff

After:

arpspoof -t 10.13.37.1 10.13.37.124

arpspoof -t 10.13.37.124 10.13.37.1

host 10.13.37.124 got disconnected from the network. I had to restart the host to bring it back online.

What am I doing wrong?

Thanks
