{{Fail2ban}} has a single (atomic) configuration file <tt>/etc/fail2ban.conf</tt> until 0.7.0. This file became quite lengthy since it keeps several kind of parameters: general settings, mail settings, section settings, etc. The proposal is to split this configuration file into several ones. fail2ban-client would process config files and provide respective commands to running fail2ban-server. So the server knows nothing about config files.
+
 
+
 
+
Every configuration files will be stored in the <tt>/etc/fail2ban</tt> directory.
+
* <tt>/etc/fail2ban/fail2ban.conf</tt> (file) will contain the general settings.
+
* <tt>/etc/fail2ban/jails.conf</tt> (file) will contain the jails definitions (one filter and one or more actions). Actions get triggered if filter matches maxfailures times within findtime
+
* <tt>/etc/fail2ban/filter.d</tt> (dir) will contain the filter settings: primarily it is failregex option. No timeregex should be necessary - they are guessed from the set of known. If not recognized - please add it as before (pre 0.7)
+
** <tt>/etc/fail2ban/filter.d/sshd.conf</tt> (file) will contain filter settings for OpenSSH server.
+
** <tt>/etc/fail2ban/filter.d/apache-auth.conf</tt> (file) will contain filter settings for Apache authentication.
+
* <tt>/etc/fail2ban/action.d</tt> (dir) will contain the action settings, ie how to react if a specific filter was matched specified (look jails.conf above) number of times
+
** <tt>/etc/fail2ban/action.d/iptables.conf</tt> (file) will contain the settings for banning an IP address using Netfilter/Iptables.
+
** <tt>/etc/fail2ban/action.d/hosts.conf</tt> (file) will contain the settings for banning an IP address using TCPWrapper.
+
Not implemented part of ideas
+
* <tt>/etc/fail2ban/pattern.d</tt> (dir) will contain regular expression templates.
+
** <tt>/etc/fail2ban/pattern.d/standard-date.conf</tt> (file) will contain a regular expression matching a standard date format.
+
* <tt>/etc/fail2ban/filter.d</tt> (dir) : The files included in this directory can benefit from the templates in <tt>/etc/fail2ban/pattern.d</tt>.
+
 
+
Any user change should be done in a <tt>''file''.local</tt> file instead of <tt>''file''.conf</tt>. First <tt>''file''.conf</tt> and then <tt>''file''.local</tt>  are read. This way, settings in <tt>.local</tt> override <tt>.conf</tt>. This should avoid conflict between user and package settings when upgrading.
