Fcron uses the cron facility of syslog to log all messages. Since LFS does not set up this facility in /etc/syslog.conf, it needs to be done prior to installing Fcron. This command will append the necessary line to the current /etc/syslog.conf (perform as the root user):
cat >> /etc/syslog.conf << "EOF" # Begin fcron addition to /etc/syslog.conf cron.* -/var/log/cron.log # End fcron addition EOF
The configuration file has been modified, so reloading the sysklogd daemon will activate the changes (again as the root user).
For security reasons, an unprivileged user and group for Fcron should be created (perform as the root user):
groupadd -g 22 fcron && useradd -d /dev/null -c "Fcron User" -g fcron -s /bin/false -u 22 fcron
Install Fcron by running the following commands:
./configure --without-sendmail --with-boot-install=no && make
This package does not come with a test suite.
Now, as the root user:
--without-sendmail: By default, Fcron will attempt to use the sendmail command from an MTA package to email you the results of the fcron script. This switch is used to disable default email notification. Omit the switch to enable the default. Alternatively, you can use the --with-sendmail=</path/to/MTA command> to use a different mailer command.
--with-boot-install=no: This prevents installation of the bootscript included with the package.
--with-editor=</path/to/editor>: This switch allows you to set the default text editor.
There are no required changes in any of the config files. Configuration information can be found in the man page for fcron.conf.
fcron scripts are written using fcrontab. Refer to the fcrontab man page for proper parameters to address your situation.
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 exiting /etc/pam.conf file. You should ensure the files match your preferences. Modify them as required to suit your needs.
Install the /etc/rc.d/init.d/fcron init script from the blfs-bootscripts-20060910 package.
