I know asking for passwords is a common theme, and I've tried to get the answer from the internet and on Cisco's website, but the problem is we have no information to start with. We don't know the PIX software version or anything.
Our internet provider installed this PIX 501 several years ago. Now they are under new ownership, and they evidently cannot provide the passwords. We would like to use it, however. But what can we do, since we do not know the version?
