mod_firewall: SUBSCRIBED: Flip subscription check to match documentation The documentation claims that this condition checks whether the recipient is subscribed to the sender. However, it was using the wrong method, and actually checking whether the sender was subscribed to the recipient. A quick poll of folk suggested that the documentation's approach is the right one, so this should fix the code to match the documentation. This should also fix the bundled anti-spam rules from blocking presence from JIDs that you subscribe do (but don't have a mutual subscription with).

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
