Change root password

I have inherited an Alpha 1000 4/266
(but no manuals) running Digital UNIX
that has not been up since 2001.
The USR partition is full, but I can't
get that taken care of until I get into
the root or superuser account.
Is there a way to assign the root account
password from the boot prompt?
Any other suggestions are certainly welcome.

Re: Change root password

I'm sure this has been addressed in this forum in detail, so if you want more detail try searching the forum.

The short answer is to boot in single user mode:
>>> boot -fl s
mount the disks:
# bcheckrc (or mount -a)
Change the root password:
# passwd

Re: Change root password


from SRM console
>> boot -fl S

will take you to songle user mode
#mount -a
#passwd root

will set new root passwd
never give up
