yppasswd(1) yppasswd(1)
NAME
yppasswd - changes a login password on the Network
Information Service (NIS) master server
SYNOPSIS
yppasswd [login-name]
ARGUMENTS
login-name
Specifies the login name of the user whose password is
to be changed. If you do not specify a value for
login-name, yppasswd attempts to change your password.
DESCRIPTION
yppasswd adds or changes a password in the /etc/passwd file
on the NIS master server. The master server must be running
the password daemon, yppasswdd, for this command to work.
Before changing an existing password, yppasswd prompts for
the old password, as stored in the /etc/passwd file on the
NIS master server, and then prompts twice for the new
password to verify your entry.
New passwords can have a minimum of four characters if they
use a sufficiently rich alphabet and must have at least six
characters if all of the characters are in the same case.
These rules are discarded if you enter the same password
often enough.
A normal user can change his or her password only. A user
who is logged in as root can change the password of any
user. In either case, yppasswd prompts for the old
password.
LIMITATIONS
The yppasswd command uses an update protocol that passes all
the information to yppasswdd in one remote procedure call,
without ever looking at it. Thus, if you type your old
password incorrectly, you are not notified until after you
have entered and verified your new password.
