Re: VLAN hopping - demonstration

[Christian Martorella <laramies2k () yahoo com ar>]

Hi all, a great tool that can do Vlan hopping and a lot of layer 2
attacks is Yersinia:

For example in vlans you can :

Send RAW VTP packet
Delete ALL VLANs
Delete selected VLAN
Add one VLAN

Check it here:  http://www.yersinia.net
