We have a security camera system running an embedded linux. It boots with Lilo as a bootloader and has no tty access once booted. I don't know any username either.
SSH/22 is open, but I don't think brute force is an option.
I have tried all the common tricks to reset a linux user password (boot from the bootloader in single user mode = doesn't happen, still prompts for user login, boot to a live cd = can't access the file system...it's all loop files and other binary, etc etc), but they are all not possible as it is an embedded linux setup the way it is.
Any help/suggestions would be appreciated. Thanks
