Hello, I have Fail2ban set with:

Ban Time: 1800
Max Ban Time: 10000
checked: ban time is incremented
IPv4 subnet: /24

I see that one subnet has racked up 8388607h 57m 17s of ban time, but they still get back in every few hours. Is this a bug? Is this some configuration parameter I missed?

Thanks!

  • Good point. I guess unbanning doesn’t clear the accumulated ban time for the respective IP/subnet. Not sure if this is a bug or intentional…

    Anyway, the “Max. ban time” value is the upper limit, as soon as this value is reached, the IP is automatically unbanned.

    Have something to say?

    I mathed that out too, but why does the UI show:

    Should it be the 10000 or what the UI shows?

        Thanks for that! I’ll file a bug and update my config. Appreciate your help.
