Re: How to change root passwd without original passwd

Are you root currently?

How about just

/sbin/passwd

(without root at the end)

Note:

Superusers are not prompted for old passwords, unless
they are attempting to change a superuser's password in a trusted
system.


Is it trusted?

Hope this helps!

Yes, the systems is in trusted mode.

 

When I put /sbin/passwd it ask me for the passwd name

 

# /sbin/passwd
Usage: passwd name
