Fedora 14 - Passwordabfrage in Runlevel S

G

Gast123

Liebe Community,

ich habe gerade mir Erschrecken festgestellt, dass (mein) Fedora 14 standardmäßig kein Passwort im Runlevel S abfragt.
Wenn man mein Notebook mit
Code:
init S
startet ist mannach dem Boot automatisch als root angemeldet.

Wie kann ich das also einstellen, dass wie z.B. bei openSUSE ein Passwort abgefragt wird?

Danke

Runlevel S ist dich RL 1?

Würde grub ein Password verpassen - dann musst du zerst das eingeben bevor du die bootoptionen anpassen kannst.
 
Hallo,

ja Runlevel S und 1 sind bei Fedora, wie bei den meisten Linux distris üblich, identisch.
Ein Bootloader Passwort lößt aber nicht mein Problem.
Ich verstehe nicht, wie ein Distributor das System so konfigurieren kann, dass man in einem bestimmten Runlevel (S) automatisch als Root angemeldet wird. Das entbehrt jeder Sicherheitspolitik.
Also, es würde mich freuen, wenn jemand eine Idee hätte, wie man auch im Runlevel 1 bei Fedora eine obligatorische Passwortabfrage hinbekommt - so wie bei openSuSE z.B.

Danke euch!
Schard
 
Was steht denn in /etc/inittab bzgl. Runlevel S? Wird dort ein bestimmtes Programm gestartet ausser z.B.
Code:
 1:2345:respawn:/sbin/getty 38400 tty1

Ein Rechner ist uebrigens erst dann sicher, wenn man den Zugang zur Hardware verhindert, von daher ist es nicht so ein enormes Risiko, bei 'init S' gleich eingeloggt zu werden. Den gleichen Zugriff haettest Du ja auch mit einer Knoppix-CD o.ae.
 
Hallo Rikola,

du hast prinzipiell recht.
Aber man kann es einem Störer auch zu einfach machen.
Also meine /etc/inittab sieht so aus (Fedora-Standard):
Code:
# inittab is only used by upstart for the default runlevel.
#
# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# System initialization is started by /etc/init/rcS.conf
#
# Individual runlevels are started by /etc/init/rc.conf
#
# Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf
#
# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,
# with configuration in /etc/sysconfig/init.
#
# For information on how to write upstart event handlers, or how
# upstart works, see init(5), init(8), and initctl(8).
#
# Default runlevel. The runlevels used are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
# 
id:5:initdefault:
Ich habe des Weiteren schon dies hier versucht. Hatte aber keine Auswirkung.
Dieses /sbin/sulogin aus diesem Forum ist hingegen aber genau das, was ich von openSuSE kenne und gerne hätte.

LG

Edit:

Ein Standardbenutzer sollte an einer Workstation arbeiten können ohne durch eine Sicherheitslücke root werden zu können.
Dabei spielt die Situation der Hardware außerdem erst ein Mal keine Rolle.
 
Sicher, dass das die gesamte inittab ist??? Steht ja mal nix drin. Wenn ja, musst Du Dir wohl /etc/init/rc.conf
# Individual runlevels are started by /etc/init/rc.conf
anschauen. Aber meinem Verstaendnis von init nach scheint fedora schon ziemlich damit und dem kernel rumgepfriemelt haben, damit diese inittab ueberhaupt etwas bewirkt...
 
Hi,

also da gibts bei mir noch die /etc/rc.d/rc:
Code:
#! /bin/bash
#
# rc            This file is responsible for starting/stopping
#               services when the runlevel changes.
