in Categories CentOS, RedHat and Friends last updated December 28, 2011
I‘ve created a file as follows:
ls -l -Z /etc/cron.d/vnstat
-rw-r–r–. root root system_u:object_r:system_cron_spool_t:s0 /etc/cron.d/vnstat
I’ve created a new file /etc/cron.d/vnstat.custom.interface:
ls -l -Z /etc/cron.d/vnstat.custom.interface
-rw-r–r–. root root unconfined_u:object_r:system_cron_spool_t:s0 /etc/cron.d/vnstat.custom.interface
The /etc/cron.d/vnstat is part of default vnstat package. I’ve installed my own version of the same. But, due to SELinux security cron job is not running. How do I change file SELinux security contex under RHEL / CentOS 6 Linux server to system_u:object_r:system_cron_spool_t:s0 from unconfined_u:object_r:system_cron_spool_t:s0 for /etc/cron.d/vnstat.custom.interface file?
