Which CRON jobs are needed?

[KoS]

I see that there are many cron jobs available in the configuration and was wondering which of them I need to add/activate.

E.g. there is a update and reload firewall aliases cron job available. I have configured some URL Table (IPs) firewall aliases and have set a refresh frequency. As far as I can see from the log files of my web server where the aliases are being downloaded, they are being downloaded in regular intervals, even without having a cron job update and reload firewall aliases added in the cron job list.

How do I know which cron jobs i need to add and which are anyways "somehow" being executed in the background?

Thanks for clarification.

afaiu they don't actually use cron to update aliases with update frequency set. looks like API call to configd (something like "configctl filter refresh_aliases"). and update frequecy is a <ttl> value in filter_tables.conf.

so you can not see this schedule in cron. but you can set your own in cron with predefined job (update and reload firewall aliases) and disable TTL in alias definition.

Thanks Fright for the clarification. Makes sense but is just not that obvious :-)
