+
+3rd Party Tools
+---------------
+
+In addition to the tools Friendica includes, some 3rd party tools can make your admin days easier.
+
+### Fail2ban
+
+Fail2ban is an intrusion prevention framework ([see Wikipedia](https://en.wikipedia.org/wiki/Fail2ban)) that you can use to forbid access to a server under certain conditions, e.g. 3 failed attempts to log in, for a certain amount of time.
+
+The following configuration was [provided](https://forum.friendi.ca/display/174591b4135ae40c1ad7e93897572454) by Steffen K9 using Debian.
+You need to adjust the *logpath* in the *jail.local* file and the *bantime* (value is in seconds).
+
+In */etc/fail2ban/jail.local* create a section for Friendica:
+
+       [friendica]
+       enabled = true
+       findtime = 300
+       bantime  = 900
+       filter = friendica
+       port = http,https
+       logpath = /var/log/friend.log
+       logencoding = utf-8
+
+And create a filter definition in */etc/fail2ban/filter.d/friendica.conf*:
+
+       [Definition]
+       failregex = ^.*Login\.php.*failed login attempt.*from IP <HOST>.*$
+       ignoreregex =
+
+Additionally you have to define the number of failed logins before the ban should be activated.
+This is done either in the global configuration or for each jail separately.
+You should inform your users about the number of failed login attempts you grant them.
+Otherwise you'll get many reports about the server not functioning if the number is too low.
+
+### Log rotation
+
+If you have activated the logs in Friendica, be aware that they can grow to a significant size.
+To keep them in control you should add them to the automatic [log rotation](https://en.wikipedia.org/wiki/Log_rotation), e.g. using the *logrotate* command.
+
+In */etc/logrotate.d/* add a file called *friendica* that contains the configuration.
+The following will compress */var/log/friendica* (assuming this is the location of the log file) on a daily basis and keep 2 days of back-log.
+
+       /var/log/friendica.log {
+               compress
+               daily
+               rotate 2
+       }
