NAME¶

fail2ban - a set of server and client programs to limit brute force authentication attempts.

DESCRIPTION¶

Fail2Ban consists of a client, server and configuration files to limit brute force authentication attempts. The server program fail2ban-server is responsible for monitoring log files and issuing ban/unban commands. It gets configured through a simple protocol by fail2ban-client, which can also read configuration files and issue corresponding configuration commands to the server. For details on the configuration of fail2ban see the jail.conf(5) manual page. A jail (as specified in jail.conf) couples filters and actions definitions for any given list of files to get monitored. For details on the command-line options of fail2ban-server see the fail2ban-server(1) manual page. For details on the command-line options and commands for configuring the server via fail2ban-client see the fail2ban-client(1) manual page. For testing regular expressions specified in a filter using the fail2ban-regex program may be of use and its manual page is fail2ban-regex(1).
