In the current version (GOS 4, GVM 9), it is necessary to create multiple schedules for a more sophisticated scheme. For example: scanning every week but only on Mondays, Wednesdays and Fridays.
We extended the capabilities of the internal scheduler by adding support for the iCalendar (rfc5545) standard. Of course this standard is far too complex to implement all of it, but we implemented a couple of rules and it will be straight forward to add more if needed.
The Web-UI dialogs are extended as well for several use cases. The above example is now very easy to configure with a single schedule:
Scan every 1st and 10th of a month:
Scan the every first Monday of a month:
