I have been messing with ettercap for some time now and understand how it works on the application, protocol, OSI levels, etc.
What I'm not sure about is the harware.
I know that switches work at the layer 2 (MAC) and sometimes layer 3 (network/vlans).
In this case I'm using DLink and 3Com unmanaged workgroup switches. All layer 2.
I have not had an opportunity to play with it on managed switches of any type... as my experimenting is limited mostly to my home network.
Can using a program like ettercap damage a switch? Since it is forcing it to act as a hub and repeat all traffic through all ports...
Thanks in advance!
