Properly Arp Cache Poisoning

[Leandro Quibem Magnabosco <leandro.magnabosco () fcdl-sc org br>]

Hello guys,

Recently I attempted an Arp Cache Poisoning to sniff over switched 
connections.
The problem is that it works against my home computer but not against my 
laptop.
When I try to sniff my laptop, it get DoS'ed.
Sniffing my Desktop it all goes smoothly.

What could be influential in this other than doing something wrong like 
a miss clicking onto another IP on ettercap or something or whatever?
I tried this 5 times last night and I was pretty confused why I could 
not sniff my laptop and could sniff my Desktop.
The ARP tables are as it should be for sniffing... this is where I wonder.

Put your thoughts here so I can test it again this evening.and maybe get 
it to work.
Tomorrow I will tell you if something else went wrong or what did I do 
to fix the issue.

Thank you.
