The class handles the initialisation of a filter, and actions. It's role is then to act as an interface between the filter and actions, passing bans detected by the filter, for the actions to then act upon. Parameters ---------- name : str Name assigned to the jail. backend : str Backend to be used for filter. "auto" will attempt to pick the most preferred backend method. Default: "auto" db : Fail2BanDb Fail2Ban persistent database instance.
