Cisco Router Break In

Had to break into another Cisco router that I didnt know the password for.  Its real simple if you have physical access, which is why you keep your gear behind secured doors.  Change the config register and you are in.

Readonly ROMMON initialized
rommon 1 >
rommon 1 > confreg 0x2142

You must reset or power cycle for new config to take effect
rommon 2 > reset

System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1)
Technical Support:

PLD version 0x10

Change it back to 0x2102 when you are in.
