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


       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).


       Fail2Ban  is  able  to  reduce  the  rate of incorrect authentications attempts however it
       cannot eliminate the risk that weak authentication presents.  Configure  services  to  use
       only  two factor or public/private authentication mechanisms if you really want to protect

       A local user is able to inject messages into syslog and using a Fail2Ban jail  that  reads
       from  syslog, they can effectively trigger a DoS attack against any IP. Know this risk and
       configure Fail2Ban/grant shell access accordingly.
