Sorry, accidentally sent mail without highlighting the line:

static void fail2ban_event_handler(switch_event_t *event)
{
<------>if (event->event_id == SWITCH_EVENT_CUSTOM && strncmp(event->subclass_name, "sofia::register_attempt",23) == 0) {
<------><------>switch_file_printf(logfile, "A registration was atempted ");
<------><------>switch_file_printf(logfile, "%s:%s ", "User", switch_event_get_header(event, "to-user"));
<------><------>switch_file_printf(logfile, "%s:%s ", "IP", switch_event_get_header(event, "network-ip"));
<------><------>switch_file_printf(logfile, "\n");
<------>} else if (event->event_id == SWITCH_EVENT_CUSTOM && strncmp(event->subclass_name, "sofia::register_failure",23) == 0) {
<------><------>switch_file_printf(logfile, "%s ",  switch_event_get_header(event, "Event-Date-Local"));
<------><------>switch_file_printf(logfile, "A registration failed ");
<------><------>switch_file_printf(logfile, "%s:%s ", "User", switch_event_get_header(event, "to-user"));
<------><------>switch_file_printf(logfile, "%s:%s ", "IP", switch_event_get_header(event, "network-ip"));
<------><------>switch_file_printf(logfile, "\n");
<------>}

}


Now I can run fail2ban with my logs set to a lower verbosity which is a pretty big deal since I have high traffic patterns.


Regards,

Guillermo

Figured out what was wrong...

Reading in the fail2ban web page I found this:

  • In order for a log line to match your failregex, it actually has to match in two parts: the beginning of the line has to match a timestamp pattern or regex, and the remainder of the line has to match your failregex. If the failregex is anchored with a leading ^, then the anchor refers to the start of the remainder of the line, after the timestamp and intervening whitespace.
  • The pattern or regex to match the time stamp is currently not documented, and not available for users to read or set. See Debian bug #491253. This is a problem if your log has a timestamp format that fail2ban doesn't expect, since it will then fail to match any lines. Because of this, you should test any new failregex against a sample log line, as in the examples below, to be sure that it will match. If fail2ban doesn't recognize your log timestamp, then you have two options: either reconfigure your daemon to log with a timestamp in a more common format, such as in the example log line above; or file a bug report asking to have your timestamp format included.

mod_fail2ban does NOT include any timestamps in the logs it generates (see my previous mail).  So I modified it to include one.  Recompiled, etc. and now it is working like a charm.

I only added on line to the original source, here highlighted in bold:



static void fail2ban_event_handler(switch_event_t *event)
{
if (event->event_id == SWITCH_EVENT_CUSTOM && strncmp(event->subclass_name, "sofia::register_attempt",23) == 0) {

<------><------>switch_file_printf(logfile, "%s:%s ", "User", switch_event_get_header(event, "to-user"));
<------><------>switch_file_printf(logfile, "%s:%s ", "IP", switch_event_get_header(event, "network-ip"));
<------><------>switch_file_printf(logfile, "\n");
<------>} else if (event->event_id == SWITCH_EVENT_CUSTOM && strncmp(event->subclass_name, "sofia::register_failure",23) == 0) {

<------><------>switch_file_printf(logfile, "%s:%s ", "IP", switch_event_get_header(event, "network-ip"));
<------><------>switch_file_printf(logfile, "\n");
<------>}

}

Has anyone tried this but with mod_fail2ban?  I cant get it to work.  I am logging to /usr/local/freeswitch/log/fail2ban.log.  I see entries there like:

I have the following in /etc/fail2ban/filter.d:

failregex = A registration failed User:.* IP:<HOST>

ignoreregex =


I never get any matches...  I have tested the regexp at http://regex101.com and it works there for PCRE and Python.

I have tried this with both fail2ban version 0.8.1.3 and 0.9.4.

Any ideas?

Thanks,

Guillermo

So, to only block failures does this regex look right? I basically just removed "failure|challenge" and replaced with "failure"

failregex = ^\.\d+ \[WARNING\] sofia_reg\.c:\d+ SIP auth (failure) \((REGISTER|INVITE)\) on sofia profile \'[^']+\' for \[.*\] from ip <HOST>$
