This is important - reloading ensures that changes made to the deny.conf file are recognized. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? I can still log into to site. inside the jail definition file matches the path you mounted the logs inside the f2b container. These will be found under the [DEFAULT] section within the file. Premium CPU-Optimized Droplets are now available.

My dumbness, I am currently using NPM with a MACVLAN, therefore the fail2ban container can read the mounted logs and create ip tables on the host, but the traffice from and to NPM is not going to the iptables of the host because of the MACVLAN and so banning does not work.
