#summary Log failed authentication attempts with their IP address
#labels Stage-Stable

= 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
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:

enabled = true
port    = 5222
filter  = prosody-auth
logpath = /var/log/prosody/prosody*.log
maxretry = 6
