I have a cisco 7940 with sip firmware on it. How do I recover the config password? I can’t seem to find any articles on it.
brute force… write a simple expect script to telnet into the thing and try a password received from std-in, the print to std-out if it gets a prompt indicating success. Then you run the script, piping into it a dictionary file with a bazillion passwords. More brute force… get bigger dictionary file.
Before getting too fancy, make sure to try the default password “cisco”.
There is another way but it shouldn’t be published here. Talk to your Cisco sales rep.
Anyone else have any recommendations?
