FAIL2BAN(1)		    General Commands Manual		   FAIL2BAN(1)

NAME
       fail2ban	- a set	of server and client programs to limit brute force au-
       thentication 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  fail2ban-
       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 mon-
       itored.

       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).

LIMITATION
       Fail2Ban	 is  able  to reduce the rate of incorrect authentications at-
       tempts 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 services.

       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.
