mod_c2s_conn_throttle: Reduce log level from error->info
Our general policy is that "error" should never be triggerable by remote
entities, and that it is always about something that requires admin
intervention. This satisfies neither condition.
The "warn" level can be used for unexpected events/behaviour triggered by
remote entities, and this could qualify. However I don't think failed auth
attempts are unexpected enough.
I selected "info" because it is what is also used for other notable session
lifecycle events.

--- labels: - 'Stage-Stable' 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 Compatibility ------------- ------- -------------- trunk Works 0.9 Works 0.8 Doesn't work ------- --------------
