Password help

[laolinux]

this is the output ....when i run the command 'passwd' for change password ... i use redhat 7.3
root]# passwd
Changing password for user root.
passwd: Module is unknown

[jnev]

he is asking the output of which passwd!!! not passwd...

also, why are you using such an old distro?

[laolinux]

# which passwd
/usr/bin/passwd

[budman7]

That command was run as the normal user.
In order to change the root password, you have to be logged in as root.

Try

su

or

su -

Then your root password.

Now you can do

passwd

That command "which passwd" if run as root, will give /usr/sbin/passwd, if not, the only way I see around it is to login in single user mode, I haven't had to do this so I can't explain how, and try to do "passwd" from there.

[laolinux]

i already did it ... here

[support@example support]$ su -
Password:
[root@example root]# passwd
Changing password for user root.
passwd: Module is unknown

[root@example root]# which passwd
/usr/bin/passwd
[root@example root]#

[scm]

Have you checked the system logs to see if there's any clues in there? On Redhat it's probably /var/log/messages, but there may be others which are written to. "ls -lrt" will give a list in time order, reapeat the passwd command to generate the error, then look at which files have just been written and see what their last entries say.

The fix is to reinstall pam

[Moi!]

I had the same error. It was because a libpam-*** was missing.
Be sure that you have all libpam installed.
(check errors at /var/log/auth.log)

(I use Debian.)
