I’ve got to redo it, but it’s a work in progress. Still saving money compared to buying a rack. Total investment so far in this I think is around $100-$150.

I’ll probably make a dedicated page on here to the rack building, but I just wanted to update the blog

Edit: here is the page http://www.riscit.info/server-rack/

Adafruit Arduino Motorshield, completely assembled and working – $10
3v Sparkfun FTDI – $10
3 Sparkfun xbee breakout boards (two have headers I soldered on) – $5 for all three
Tankbot from budgetrobotics.com, with the third deck – $45
two Xbees, 1mW with chip antennas – $20 each
Arduino Pro Mini 328 – 5V/16MHz – $15
5v Sparkfun FTDI – $10
Xbee Explorer Regulated Board – $5
Xbee Explorer USB Board – $15
Parallax RFID reader serial, brand new – $25

Here’s my project page I will be keeping updates on: http://www.riscit.info/wopr/

Well, I was able to use HyperTerminal and a serial cable to connect to it successfully, so I started from there. When you first connect to the router, use N-8-1 (or, No parity, 8 data bits, 1 stop bit) at 9600Baud. However, be careful, the Centillion 50/100 and 5000BH Models may reset if you press a key at the terminal before the CLI prompt appears.

Now you will want to login the engineer prompt using eng and the password is debug. This is an account, from my understanding, for network engineers to check out debug information in case something is wrong with the router.

Now you will need to access the what? prompt. The what? helps with the output of the raw debug data, again, as far as I can tell. There is nothing in the manuals about the eng and what? prompts at all.

Now, you begin the real work. You must dump the data in the flash memory. To do this you issue the command: d 0bfc60000 and hit ENTER

You will need to continue to dump this until you see a double 12C pattern. To continue dumping, press d and hit ENTER. Just about 12 bytes before this 12C pattern is the password in hex. I had to continue dumping this data about 5 or 6 times till I got the double 12C pattern. You will see the password on my C100 was: 313233343536. Which, when converted is 123456. Since: 31 = 1, 32 = 2, 33 = 3, 34 = 4, 35 = 5, 36 = 6 in hex.

Apparently in firmware verison 2.0.2 and above, password recovery is not possible from the CLI. Access to the enginnering or what? prompts requires the user password. To fix this, you will need to reprogram your flash.

CBS embedding video into magazines – I see this and think that maybe it’s inspiration came from movies.  Pretty awesome.
