Ciox notes (Anthony C. Zboralski Gaius)

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

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

Let's look around:

ep#show proc
CPU utilization for five seconds: 10%/4%; one minute: 14%; five minutes: 14%
PID QTy PC Runtime (ms) Invoked uSecs Stacks TTY Process
