Dotaz: nefunkcni passwd

[$]

Ahoj, nevite nekdo proc mi nejde zmenit heslo? Root muze menit hesla normalni uzivatel ne:

a@b:~$ passwd
Changing password for a
(current) UNIX password: 
Enter new UNIX password: 
Retype new UNIX password: 
Password unchanged
Enter new UNIX password: 
...

Debian 3.1 (Bastille); /usr/bin/passwd prava 106755.

normální user může taky měnit heslo, ale jenom svoje.
Zkus to ve formě passwd user u roota pak passwd root

kdyz jako normalni user zadam passwd tak to nejde

a@b:~$ passwd
Changing password for a
(current) UNIX password: 
Enter new UNIX password: 
Retype new UNIX password: 
Password unchanged
Enter new UNIX password: 
   ...

jako root to funguje, ale ja potrebuju aby si to moh menit sam uzivatel.

Nepíšeš náhodou pořád stejné heslo? Ti to tam píše Password unchanged, zkus si to přeložit...

Myslim, ze jsem podivne hloupou hlasku videl, kdyz konfigurace PAMU nedovolovala zmenit si heslo. Podivejte se do /etc/pam.d/passwd.

/etc/pam.d/passwd :

#
# The PAM configuration file for the Shadow `passwd' service
#

@include common-password

/etc/pam.d/common-password

#
# /etc/pam.d/common-password - password-related modules common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of modules that define  the services to be
#used to change user passwords.  The default is pam_unix

# The "nullok" option allows users to change an empty password, else
# empty passwords are treated as locked accounts.
#
# (Add `md5' after the module name to enable MD5 passwords)
#
# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
# login.defs. Also the "min" and "max" options enforce the length of the
# new password.

password   required   pam_unix.so nullok obscure min=4 max=8 md5

# Alternate strength checking for password. Note that this
# requires the libpam-cracklib package to be installed.
# You will need to comment out the password line above and
# uncomment the next two in order to use this.
# (Replaces the `OBSCURE_CHECKS_ENAB', `CRACKLIB_DICTPATH')
#
# password required	  pam_cracklib.so retry=3 minlen=6 difok=3
# password required	  pam_unix.so use_authtok nullok md5

Případně zkuste to samé, ale pod rootem ... tedy passwd $USER.
