Ciscox notes (Anthony C. Zboralski Gaius)

Research is being done on a useless Cisco 1600 with 4 megs of flash
running IOS 11.1.

Recently after writting my first cisco warez (tunnelx), I told myself hey
we need to find a way to inject arbitrary code, poke and peek at the memory
on a cisco, hide interfaces, route-maps, access-lists.

Let's look around:
