The system goes up without my password

English Install/Boot/Login
#1

I am using OpenSuse 12.3 and KDE

In “System Settings”, I Keep unchecked the option “enable authentication without password”

But in the login screen, if I type enter, without my password (blank), the system goes up.

Thus anyone comes into my pc.

What should I do to prevent this?

To me it looks as if you have no password for that user. Didn’you provide one at installation?

Try from a terminal (as the user involved):

passwd

It will first ask you for the old password, because it seems to be empty hit the return key. Then it will ask you twice for your new password. That should give you a password.

#3

Have a look at this setting in /etc/sysconfig/displaymanager:

## Type:        yesno
## Default:     no
#
# Allow all users to login without password, but ask for the user, if
# DISPLAYMANAGER_AUTOLOGIN is empty.
#
DISPLAYMANAGER_PASSWORD_LESS_LOGIN="no"
#4

My password is not empty, look below (## my translation)
First time, I just pressed enter
Second time I typed my password

sergio@linux-l78t:~> passwd
Mudando senha para sergio. ## Changing password for sergio
Senha UNIX (atual): ##UNIX password (current):
passwd : Falha de autenticação ## Authentication failed
passwd: senha inalterada ##password unchanged
sergio@linux-l78t:~> passwd
Mudando senha para sergio. ##Changing password for sergio.
Senha UNIX (atual): ##UNIX password (current):
Nova senha: ## New password:
UNIX password (current):

Ok, so sergio has a pssword and you know it. Then my asumption was wrong.

Did you check what wolfi 323 suggested?

Just a comment. When the system language is not English, you should do,
in order to post here, like this:


minas-tirith:~ # LANG=en_US.UTF-8 zypper info kvm
Loading repository data...
Warning: Repository 'openSUSE-11.4-Update' appears to outdated. Consider
using a different mirror or server.
Reading installed packages...

or this:


minas-tirith:~ # LANG=C zypper info kvm
Loading repository data...
Warning: Repository 'openSUSE-11.4-Update' appears to outdated. Consider
using a different mirror or server.
Reading installed packages...
^C

That way we can all read it, regardless of local languages of sender and
reader. It is not a permanent change, it only applies to one command.

Thank you very much, Wolf323.

I followed your advice and now the system only goes up if you use the correct password.

#8

Nice it works. But your system was already up. This is only about the login. Try to understand the difference.

#9

You mean that if I get the login window, then the system is already up?

As Carlos said: of course.
After all you can login and logout and login again. And other people can do likewise (it is a multi-user system). Either localy (more logical screens) or from remote. There are Unix/Linux systems where hundreds of people are login in/out during the day and the system is up and running all the time.

Also a system that mainly acts as a server (wev server e.g.) will be up and serving after boot. Even when nobody is loged in.

I understood
Thank you for the explanation.
