Split configuration file
Fail2ban has a single (atomic) configuration file /etc/fail2ban.conf 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 /etc/fail2ban directory.
- /etc/fail2ban/fail2ban.conf (file) will contain the general settings.
- /etc/fail2ban/jails.conf (file) will contain the jails definitions (one filter and one or more actions). Actions get triggered if filter matches maxfailures times within findtime
- /etc/fail2ban/filter.d (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)
- /etc/fail2ban/filter.d/sshd.conf (file) will contain filter settings for OpenSSH server.
- /etc/fail2ban/filter.d/apache-auth.conf (file) will contain filter settings for Apache authentication.
- /etc/fail2ban/action.d (dir) will contain the action settings, ie how to react if a specific filter was matched specified (look jails.conf above) number of times
- /etc/fail2ban/action.d/iptables.conf (file) will contain the settings for banning an IP address using Netfilter/Iptables.
- /etc/fail2ban/action.d/hosts.conf (file) will contain the settings for banning an IP address using TCPWrapper.
Not implemented part of ideas
- /etc/fail2ban/pattern.d (dir) will contain regular expression templates.
- /etc/fail2ban/pattern.d/standard-date.conf (file) will contain a regular expression matching a standard date format.
- /etc/fail2ban/filter.d (dir) : The files included in this directory can benefit from the templates in /etc/fail2ban/pattern.d.
Any user change should be done in a file.local file instead of file.conf. First file.conf and then file.local are read. This way, settings in .local override .conf. This should avoid conflict between user and package settings when upgrading.
