Dans /opt/systools, créer maj_scripts.sh

Ne pas oublier
chmod 700 maj_scripts.sh
Puis créer juste les noms des scripts pour une première mise à jour. Ex :
touch ossec-local-rules.sh touch dumpmysql.sh touch check_services.sh
Et planifier tout de suite ces scripts pour ne pas oublier !
cd /etc/cron.hourly ln -s /opt/systools/check_services.sh cd /etc/cron.daily ln -s /opt/systools/ossec-local-rules.sh ln -s dumpmysql.sh
Planifier aussi maj_scripts par un lien dans /etc/cron.daily, En tête de liste pour qu'il se lance avant les autres scripts, et le lancer une première fois manuellement.
cd /etc/cron.daily ln -s /opt/systools/maj_scripts.sh 0maj_scripts.sh ./0maj_scripts.sh ls -l /opt/systools/
