[Discuss] Forgotten users and passwords in Debian

[Murray Strome]

I have an old computer on which I installed Debian some time ago (this 
was in order to get the library software, Koha, to work).  I have not 
looked at that computer for many months, and now realize that I have 
completely forgotten all the user names and passwords and the root 
password.  Without having to install everything (it took days to get it 
working the first time because Koha installation is so complicated), I 
really don't want to try that. I tried booting in Rescue mode, but it 
wants the root password which I don't remember.

Even if I could get to the list of users, presumably in /etc, it might 
twig my memory about one or more of the user passwords.

Any ideas?

Thanks.
