NAME
mkpasswd - generate new password, optionally apply it to a
user
SYNOPSIS
mkpasswd [ args ] [ user ]
INTRODUCTION
mkpasswd generates passwords and can apply them automati-
cally to users. mkpasswd is based on the code from Chapter
23 of the O'Reilly book "Exploring Expect".
USAGE
With no arguments, mkpasswd returns a new password.
mkpasswd
With a user name, mkpasswd assigns a new password to the
user.
mkpasswd don
The passwords are randomly generated according to the flags
below.
FLAGS
The -l flag defines the length of the password. The default
is 9. The following example creates a 20 character password.
mkpasswd -l 20
The -d flag defines the minimum number of digits that must
be in the password. The default is 2. The following exam-
ple creates a password with at least 3 digits.
mkpasswd -d 3
The -c flag defines the minimum number of lowercase alpha-
betic characters that must be in the password. The default
is 2.
The -C flag defines the minimum number of uppercase alpha-
betic characters that must be in the password. The default
is 2.
The -p flag names a program to set the password. By
default, /etc/yppasswd is used if present, otherwise
/bin/passwd is used.
The -2 flag causes characters to be chosen so that they
alternate between right and left hands (qwerty-style),
making it harder for anyone watching passwords being
entered. This can also make it easier for a password-
guessing program.
The -v flag causes the password-setting interaction to be
visible. By default, it is suppressed.
EXAMPLE
The following example creates a 15-character password that
contains at least 3 digits and 5 uppercase characters.
mkpasswd -l 15 -d 3 -C 5
