    Terminal Login takes me straight to root prompt without auth!

    Hi,

    I have recently installed Debian on a low end PPC machine. I have changed the root password but when I login via putty using telnet or SSH I do not get prompted for a login; instead I see the root prompt immediately.

    I created another user but still no auth.

    Obviously this is not a good way to run a linux box

    If i type the following I do get the correct authentication:

    login

    How can I change the login process so a login/pass prompt appears straight away?

    I have search a lot of forums but to no avail....

    Thanks in advance.

    Paul.

    Default Debian

    My installation is pretty much the default debian installation. I have made a few minor typical modifcations e.g. network setup, samba service, proftpd.

    From the very first day I installed Debian the root prompt has been present at remote terminal login without auth.

    Any ideas??? Even some insight as to how a remote telnet session is processed by *nix machine would be usefull.

    Thanks,

    PC.

    No getty - inittab configuration?

    Yip no getty process. Never came across this program till now. As it handles logins I am assuming an entry would need to be added to inittab as it is not present.

    What do I need to add to it?

    BTY any ideas why I cannot find this post on the main Debian forum listing??

    Here is my inittab file:

    Code:
    # /etc/inittab: init(8) configuration.
# $Id: inittab,v 1.91 2002/01/25 13:35:21 miquels Exp $

# The default runlevel.
id:2:initdefault:

# Boot-time system configuration/initialization script.
# This is run first except when booting in emergency (-b) mode.
# /etc/inittab: init(8) configuration.
# $Id: inittab,v 1.91 2002/01/25 13:35:21 miquels Exp $

# This is run first except when booting in emergency (-b) mode.

~~:S:wait:/sbin/sulogin

# /etc/init.d executes the S and K scripts upon change
# of runlevel.
#
# Runlevel 0 is halt.
# Runlevel 1 is single-user.
# Runlevels 2-5 are multi-user.
# Runlevel 6 is reboot.

# Normally not reached, but fallthrough in case of emergency.

    Changed file and restarted - did not work.

    When I type:

    tty

    I get:

    /dev/pts/0

    Cannot find an answer on this anywhere on the net...

    Update:

    When I boot the machine no getty processes appear. However when I use the:

    init q

    command several getty processes appear.

    But still no login prompt!?

    ps -ax output:

    before you order the command : init q , see the dmesg , looking for any error.

    EDIT:
    and delete one of this entry

    # The default runlevel.
    id:2:initdefault:
