mod_adhoc_dataforms_demo: Fix duplicate field prevention It's supposed to only include each type of form field once per form at most but it didn't note which fields it had added already. No idea what the probability was anyways, probably pretty low.

summary: Log failed authentication attempts with their IP address
...

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 \(not-authorized\) for user .* 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
