[TriLUG] Lost password for FreeBSD box

[Matt Pusateri]

Triluggers,

How about a plain Ctrl-alt-del (may be disabled) and when it reboots
go to single user mode? If it's a newer FreeBSD version there's a
single user mode on the menu if not you can interupt the boot process
and use -s.  Then just reset the root pwd.
