Login problem

satimis · 08-23-2005, 11:48 PM

Hi folks,

BLFS 6.1
FC3 Host

On chroot environment after having installed
CrackLib-2.8.3
http://www.linuxfromscratch.org/blfs.../cracklib.html
Linux-PAM-0.80
http://www.linuxfromscratch.org/blfs...linux_pam.html

reinstalled Shadow-4.0.9 according to the book;
http://www.linuxfromscratch.org/blfs...fs/shadow.html

I was held on 'login' (with CrackLib), saying "bash: /etc/pam.d/login: No such file or directory"

According to the "Warning" near the bottom on the same page, reinstalled Shadow-4.0.9 with "--without-libpam" and also moved the /etc/login.defs.orig backup file to /etc/login.defs

Now I can't login LFS 6.1 with following warning;
Login:PAM Failure, aborting: Critical error - immediate abort

I did it twice including removing the source tree of Shadow-4.0.9 and download new packages from Internet as well

What I discovered are follows;

[root@localhost satimis]# find /mnt/lfs/ -name login.defs

Code:

/mnt/lfs/sources/shadow-4.0.9/etc/login.defs
/mnt/lfs/etc/login.defs

[root@localhost satimis]# find /mnt/lfs/ -name security -type d

Code:

....
/mnt/lfs/etc/security
/mnt/lfs/lib/security
/mnt/lfs/usr/include/security
/mnt/lfs/usr/lib/firefox-1.0.6/chrome/en-US/locale/global/security
/mnt/lfs/usr/src/linux-2.6.11.12/security
....

[root@localhost satimis]# ls -al /mnt/lfs/etc/ | grep pam.d
[root@localhost satimis]# ls -al /mnt/lfs/etc/ | grep pam.conf
Both no printout

[root@localhost satimis]# find /mnt/lfs/ -name pam.d -type d

Code:

/mnt/lfs/sources/shadow-4.0.9/etc/pam.d
......

[root@localhost satimis]# ls -al /mnt/lfs/sources/shadow-4.0.9/etc/pam.d/

Code:

Both of them were not on;
/etc/pam.d/
/etc/pam.conf

Please advise how to fix the login problme. Whether moving pam.d and pam.conf to their correct directories.

You need to create the directory /etc/pam.d, then create the files.

Hi kjordan,

Whether I can move/cp "/mnt/lfs/sources/shadow-4.0.9/etc/pam.d/* to "/mnt/lfs/etc/pam.d". The files are there;

[root@localhost satimis]# ls -al /mnt/lfs/sources/shadow-4.0.9/etc/pam.d/

Well, I'm not sure how well those default ones will work or how they compare to the ones the BLFS instructions create, so I'd just:

install -v -m755 -d /etc/pam.d
Then follow the instructions for creating the files in the shadow section.

Hi kjordan,

BLFS 6.1
FC3 Host
chroot environment

Login revived after running;
# install -v -m755 -d /etc/pam.d

and compketing Section Shadow-4.0.9
http://www.linuxfromscratch.org/blfs...fs/shadow.html

Re: Note (on bottom of that pape)

Code:

ENV_SUPATH is no longer supported. You must create a valid /root/.bashrc file to provide a modified path for the super user.

The file already existed.

[root@localhost satimis]# cat /mnt/lfs/root/.bashrc

Code:

# Begin ~/.bashrc
# Written for Beyond Linux From Scratch
# by James Robertson <jameswrobertson@earthlink.net>

# Personal aliases and functions.

# Personal environment variables and startup programs should go in
# ~/.bash_profile.  System wide environment variables and startup
# programs are in /etc/profile.  System wide aliases and functions are
# in /etc/bashrc.

if [ -f "/etc/bashrc" ] ; then
        source /etc/bashrc
fi

# End ~/.bashrc

What shall I change here.

Login as "root'

Code:

PAM-securetty[3103]: Couldn't open /etc/securetty
....
Lgin[3098:PAM pam_putenv: delet non-existent entry :PATH

X-window and Firefox can be started.

Login as "user"

Code:

....
No directory, logging in with HOME=/
id : cannot find name for group ID100

X-window cannot be started

Please advise how to get them fixed. TIA
