bcron
Short Description
Bruce Guenter <bruce@untroubled.org>
Version 0.11
2015-08-12
This is bcron, a new cron system designed with secure operations in
mind. To do this, the system is divided into several seperate programs,
each responsible for a seperate task, with strictly controlled
communications between them. The user interface is a drop-in
replacement for similar systems (such as vixie-cron), but the internals
differ greatly.
A mailing list has been set up to discuss this and other packages.

Development versions of bcron are available at:
https://github.com/bruceg/bcron
Requirements:
- Needs ucspi-unix (or ucspi-local) to be able to accept user-submitted
crontabs.
- bglibs version 1.100 or later from http://untroubled.org/bglibs/
Installation:
- Edit the configuration in the conf-* files as necessary.
- Build the sources by running "make".
- Install the package by running "make install" as root.
Configuration:
- Create a system user and group "cron". This user will own all the
crontab files.
- Create the spool directory as follows:
mkdir -p /var/spool/cron/crontabs /var/spool/cron/tmp
mkfifo /var/spool/cron/trigger
for i in crontabs tmp trigger; do
chown cron:cron /var/spool/cron/$i
chmod go-rwx /var/spool/cron/$i
done
- Create the configuration directory /etc/bcron as follows:
mkdir -p /etc/bcron
You can put any common configuration settings into this directory,
like alternate spool directories in BCRON_SPOOL.
Operation:
- The scheduler can be started with the following command:
envdir /etc/bcron bcron-start | multilog t /var/log/bcron &
- To accept crontabs from users, run the spooler:
envdir /etc/bcron \
envuidgid cron \
unixserver -U /var/run/bcron-spool \
bcron-spool >/dev/null 2>&1 &
- To update system crontabs, run the updater:
envdir /etc/bcron \
bcron-update /etc/crontab /etc/cron.d >/dev/null 2>&1 &
- Sample run scripts are provided for operating the above commands under
svscan and supervise (or equivalents such as runit).
