Lost password and username on linux firewall box

Hello all and thanks in advance for any insight you may have.

It's been 35 years or so since I worked on a Linux type OS, so I am nearly blank. Please bear with me as I try to explain my issue.

I have inherited this job for a local company which runs a Linux machine with smoothwall as a firewall, the old IT guy left and did not leave a network map or passwords or live disks ... not a thing.

The company switch ISP from DSL and went with Mediacom cable there were no IT person there or anybody that knew anything about the system. Of course nothing is working now since the ISP and IP was changed. The cable company merely installed the modem and plugged it into the firewall ... and they were done.

That's when I come in, thinking this was going to be a simple outside IP change, I booted up the box, which also boots Smoothwall automatically and it when finally came to a stop, it wanted a Login and password ... ooops!

I can't tell which version of linux it is because everything scrolls so fast that I can't catch any linux version on boot, I even tried the "Pause/Break" key to stop the scrolling, but no luck.

Now I have been reading a lot here about how to reset the password on Linux, and from what I can understand the way to do this is to press ESC when Grub starts loading to get to the main menu where you can see a list of available kernel ... etc.

The only 2 items that show on the Grub menu are the following;


When I select Smoothwall-runtime from the above listing and press "e" to edit, this what I have;

Kernel /vmlinuz-
root=uuid=29e722ba-2d29- initrd / initrd-26-32-26+drm33.12.0-runtime.bz2

I looked at runtimebig and it is the same except runtime is replaced with runtimebig.

Since all the examples I have found here all show the Grub menu with some kind of linux name and not smoothwall, I am not sure what to do. I did not try to edit anything yet, I thought I'd better consult with someone before I screwed thing up and put those folks in even worse shape.

The Grub version is 0.97, from what I can gather, it's an older version.

well, I hope I made some sense. I am not sure if I am even on the right track, any help you can offer will be more than greatly appreciated.

It's 3:30am here ... yep, I am definitely losing sleep over this issue ... lol.

At the GRUB command line "editing" means just a temporary change. For permanent modification you need to edit GRUB files in /boot/grub, /boot/grub2 or /etc directly.

Append either " single" or " init=/bin/sh" to the end of your "root" line:
root=uuid=29e722ba-2d29- initrd/initrd-26-32-26+drm33.12.0-runtime.bz2 init=/bin/sh
If it grants you a shell run 'passwd root' to set a new password.
Also change the password for the "setup" user and any web interface virtual users.
