Hi,
I was recently trying to get fcron installed but I got stuck after
installing the blfs-bootscript for fcron. Here's what happened:
# /etc/rc.d/init.d/fcron start &&
fcrontab -z -u systab
* Starting fcron... [ OK ]
2020-05-17 21:32:27 ERROR Could not authenticate user using PAM (7):
Authentication failure
After doing some research, I stumbled across this post:
https://www.linuxquestions.org/questions/linux-security-4/cronjob-could-not-authenticate-pam-user-authentication-failure-for-root-696038/
who encountered a similar issue and I also found that the package
installed the pam configuration for fcron to /etc/pam.conf (which did
not exist before). I have read in the configuration section of fcron
stating that
"If Linux-PAM is installed, two PAM configuration files are installed in
|etc/pam.d|. Alternatively if |etc/pam.d| is not used, the installation
will append two configuration sections to the existing |/etc/pam.conf|
file. You should ensure the files match your preferences. Modify them as
required to suit your needs."
However, I do have the /etc/pam.d directory so I'm not sure why it
installed /etc/pam.conf -- perhaps I missed something but I did check
the errata and there was no entry for it. Looking at what Arch Linux
did, I've added a few lines to my install script
|mkdir -pv $PKG/etc/pam.d install -Dm644 files/fcron.pam
$PKG/etc/pam.d/fcron install -Dm644 files/fcrontab.pam
$PKG/etc/pam.d/fcrontab rm -rvf $PKG/etc/pam.conf |
where PKG is the installation directory (I used a DESTDIR install).
Finally, I reran
# /etc/rc.d/init.d/fcron start && fcrontab -z -u systab
* Starting fcron... [ OK ]
2020-05-17 21:45:04 INFO reinstalling systab's fcrontab
2020-05-17 21:45:04 INFO installing file /tmp/fcr-CI0N4s for user systab
Modifications will be taken into account right now.
so, I'm guessing that the problem was fixed as PAM seems happy now.
Was there a line that I've overlooked in the BLFS book?
