This weblog was intended primarily to have an easy way to type my documents and to make them searchable commentable etc..

After looking at my webservers webstatistics, I saw some search requests for Cisco password recovery techniques. Well then let's explain it here for everyone to read:

1) Attach a console cable to the Cisco
2) Reboot the Cisco
3) When the Cisco shows the first sign of life start sending it breaks (that's ctrl-F in minicom)
4) type confreg 0x2142
5) type reset
6) ... Cisco boots .... zZzZzZ ....
7) Enter no at the first question
8) voila a configless Cisco
9) now get into enable mode (but do NOT type conf term)
10) type copy startup running
11) voila a running cisco with full config in ENABLE mode
12) do your password changing stuff
13) type write mem
14) type config-register 0x2102 in configure mode
15) type reload

That was quite easy huh :)

This guide will grant you ACCESS to an enable prompt on a running router. It will NOT recover the actual password!
