Fail2ban Configuration

The default Fail2ban installation comes with two configuration files, /etc/fail2ban/jail.conf and /etc/fail2ban/jail.d/defaults-debian.conf. It is not recommended to modify these files as they may be overwritten when the package is updated.

Fail2ban reads the configuration files in the following order. Each .local file overrides the settings from the .conf file:

• /etc/fail2ban/jail.conf
• /etc/fail2ban/jail.d/*.conf
• /etc/fail2ban/jail.local
• /etc/fail2ban/jail.d/*.local
