The root password is unknown. Is there a way to reset it?Yes, there is a way to reset the root level password. It requires attaching a keyboard and monitor to the unit and rebooting the system. Use the control alt delete key stroke to reboot the unit. Do not power off a working unit.
During the LILO prompt (boot loader screen), type:
2.4.22 init=/bin/sh rw
Then at the (none):/# prompt type:
passwd (this will allow you to define your own root password)
Then enter the sync command three seperate times:
Then at the prompt reboot the unit with:
exec /sbin/init 6
and let it boot up normally.
