Wow, that is a flood of information and it kind of makes sense. I'd need to be running ESXi which I'm currently not but could try. I think I've got a long way to go on low lever networking to be doing anything more than trying to hop from VLAN to another and seeing what sniffers pick up on different network segments. The joys of coming down the stack from developer rather than up from sys-admin.
