Hello, I'm trying to user fail2ban with a specific program (heyu) but I can't get rid of the timeregex and timepattern, I'm still getting the error message below: Found a match for '07/03 23:53:05 rcva func RFdata : Type VISONIC ID 0xc9a9d2 Data 0x0c ' but no valid date/time found for '07/03 23:53:05 rcva func RFdata : Type VISONIC ID 0xc9a9d2 Data 0x0c In my .conf file I'm using the following: timeregex = \d{2}/\d{2} \d{2}:\d{2}:\d{2} timepattern = %%m/%%d %%H:%%M:%%S failregex = RFdata : Type VISONIC ID (?P<host>\S+) Data 0x0c\s*$ Did I made something wrong the regex ? Any help would be greatly appreciated ! Thanks. Jérôme.
