na_passwd - modify the system administrative user's password
passwd
rsh-only usage:
passwd oldpassword newpassword [ username ]
passwd changes the filer's administrative user's password.
First it prompts you for the login name (if any non-root
users are configured). Then, if you are not logged in as
the root user, it prompts you for the current password. If
you type the current password correctly (or were the root
user and weren't required to type in the current password),
the filer requests a new password. The passwd command
imposes no minimum length or special character
requirements for " root " or for " Administrator ". As
with any password, it is best to choose a password
unlikely to be guessed by an intruder. All non-root administrative
user's passwords should meet the following
restrictions:
- - it should be at least 6 characters long
-
- - it should contain at least two alphabetic characters
-
- -
- it should contain at least one digit or special
character
By default, the above criteria are enforced by the filer
when a new password is given. However, the security.passwd.rules.enable
option can be used to prevent the
restrictions from being enforced. See na_options(1) for
additional information.
If the filer is booted from floppy disk, selection "(3)
Change password" enables you to reset the "root" password
without entering the old password. This is useful for the
forgetful.
The second style of using the passwd command, shown in the
SYNOPSIS above, is only allowed when you execute the password
command using rsh. (Since rsh doesn't allow prompting,
all the necessary values must be put on the commandline.)
If you do not provide an explicit username as the
third argument, "root" is assumed.
Each filer in a cluster can have a different password.
However, in takeover mode, use only the password set on
the live filer to access the consoles of both filers. You
do not need to enter the failed filer's password to execute
commands in partner mode.
Because the password for the failed filer becomes
unnecessary after a takeover, you do not have increased
security by assigning different passwords to the filers in
a cluster. Network Appliance recommends that you use the
same password for both filers.
When run from a vfiler context, (e.g. via the vfiler run
command), passwd operates on the concerned vfiler, and can
only be used to change the password of a user of that
vfiler.
