+
+= Introduction =
+
+Prosody doesn't write IP addresses to its log file by default for privacy reasons (unless debug logging is enabled).
+
+This module enables logging of the IP address in a failed authentication attempt so that those trying to break into accounts for example can be blocked.
+
+= fail2ban configuration =
+
+fail2ban is a utility for monitoring log files and automatically blocking "bad" IP addresses at the firewall level.
+
+With this module enabled in Prosody you can use the following example configuration for fail2ban:
+
+{{{
+# /etc/fail2ban/filter.d/prosody-auth.conf
+# Fail2Ban configuration file for prosody authentication
+[Definition]
+failregex = Failed authentication attempt \(not-authorized\) from IP: <HOST>
+ignoreregex =
+}}}
+
+And at the appropriate place (usually the bottom) of /etc/fail2ban/jail.conf add these lines:
+
+{{{
+[prosody]
+enabled = true
+port    = 5222
+filter  = prosody-auth
+logpath = /var/log/prosody/prosody*.log
+maxretry = 6
