h1. HowTo Configure Fail2ban For Redmine h2. Install install fail2ban with apt-get if not installed ( or use yum, pacman or another package manager) <pre> apt-get install fail2ban </pre> h2. Configure create a new file in /etc/fail2ban/filter.d/redmine.conf explanation: here we create our new filter to match failed login attempts <pre> # redmine configuration file # # Author: David Siewert # # $Revision$ # [Definition] failregex = Failed [-/\w]+ for .* from <HOST> # Option: ignoreregex # Notes.: regex to ignore. If this regex matches, the line is ignored. # Values: TEXT # ignoreregex = # Source: #http://www.fail2ban.org/wiki/index.php/MANUAL_0_8 </pre> add following lines somewhere in your /etc/fail2ban/jail.conf explanation: here we enable our newly createt filter and add some configuration options <pre> [redmine] enabled = true filter = redmine port = 80,443 #backend = polling action = iptables-allports[name=redmine] logpath = /var/log/redmine/default/production.log maxretry = 5 findtime = 7320 bantime = 7320 </pre> note 1: if you our web server uses local time, then you need to increase findtime and bantime accordingly to the drift in comparison to UTC time in my example configuration i used 2 h + 2 minutes = 3600 * 2 +120 = 7320, because my local server time was were always 2 hours earlier and i added 2 minutes just in case note 2: if you do not use redmine in production mode, then you need to change the logpath as well note 3: if this configuration does not work, you can try uncommenting "backend = polling" h2. Test if you make any changes, you can check the syntax with: <pre> fail2ban-regex /var/log/redmine/default/production.log /etc/fail2ban/filter.d/redmine.conf </pre> finally start/restart fail2ban <pre> /etc/init.d/fail2ban restart </pre> and test if you can get yourself banned :) note: your failed login attempts need to match the maxretry value in /etc/fail2ban/jail.conf
