Hello, fail2ban does not ban offending IP.

Hi list , someone on the list has seen this type of connection attempts in asterisk, fail2ban does not stop 2015-01-08 14:59:47] SECURITY[21515] res_security_log.c: SecurityEvent="ChallengeSent",EventTV="1420750787-386840",Severity="Informational",Service="SIP",EventVersion="1",AccountID="sip:100 at

If this is a small site, I recommend you download the free version of SecAst (www.telium.ca <http://www.telium.ca> ) and replace fail2ban. SecAst does NOT use the log file, or regexes, to match etc.instead it talks to Asterisk through the AMI to extract security information. Messing with regexes is a losing battle, and the lag in reading logs can allow an attacker 100+ registration

Hello Anyone have a working copy of Fail2ban asterisk filter asterisk.conf for Asterisk 16 running PJSIP. I have tried 10 different filters but none of them show any matches when testing with fail2ban-regex I see date template hits but no matches....

I need some help understanding SIP dialog. Some actor is trying to access my server, but I can't figure out what he's trying to do ,or how. I'm getting a lot of these warnings.

In https://wiki.dovecot.org/HowTo/Fail2Ban, for a current (I know for a fact in 2.2.36) I believe it should be filter = dovecot instead of filter = dovecot-pop3imap [root at mail ~]# ls -l /etc/fail2ban/filter.d/doveco* -rw-r--r-- 1 root root 1875 May 11 2017 /etc/fail2ban/filter.d/dovecot.conf [root at mail ~]#

I have turned on 'auth_debug_passwords=yes? in dovecot.conf. I?m trying to get Fail2ban to detect this log line: Sep 11 15:52:49 mail dovecot[54239]: auth-worker(10094): sql(user at bordo.com.au <mailto:user at bordo.com.au>,::1,<L2xqieNYeM4AAAAAAAAAAAAAAAAAAAAB>): Password mismatch (given password: 2) I?ve added it as the last line of my dovecot filter regex: failregex =

I'm trying to setup and test fail2ban with dovecot I've installed fail2ban, I've copied config from https://wiki2.dovecot.org/HowTo/Fail2Ban, and, trying to test it, attempted multiple mail access with wrong password, but, get this: # fail2ban-client status dovecot-pop3imap Status for the jail: dovecot-pop3imap |- Filter | |- Currently failed: 0 | |- Total failed: 0 | `- File

I'm trying to set up fail2ban with dovecot, I have it working on 'old' server Centos 6, but, not getting anywhere with 'new' server on Centos 7 using standard filters I've copied same 'filter' to new server, still get nothing any idea how to figure this out ? on old server, it logs to syslog/messages CentOS release 6.10 (Final) dovecot 2.3.10.1 (a3d0e1171) old #

For dovecot 2.1 as per wiki2, is this still valid? noticed a problem before and saw it does seem to be triggering, I use: maxretry = 6 findtime = 600 bantime = 3600 and there was like, 2400 hits in 4 minutes, it is pointing to the correct log file, but I am no expert with fail2ban, so not sure if the log format of today is compatible with the wiki2 entry filter.d/dovecot.conf [Definition]

Hi to all, @Olaf Hopp I've this filter enabled for fail2ban, my question is: could my filters overlap or interfere with those suggested by you? this is my filter: Contents of /etc/fail2ban/jail.conf: [postfix] # Ban for 10 minutes if it fails 6 times within 10 minutes enabled = true port = smtp,ssmtp filter = postfix logpath = /var/log/mail.log maxretry = 6 bantime = 600

Just a note that I did a little work to extend FreePBX distro with some extra Fail2Ban which deals with some drive-by SIP registration attempts. My regex is poor to middling, but the steps detailed here: http://www.coochey.net/?p=61 manage to stop IPs which try to authenticate against Asterisk which FreePBX were not able to stop before. I would welcome any improvements anyone would care to

I'm currently using postfix and dovecot, with dovecot authentication (with saslauthd) using mysql for accounts Is there any option available for me to help inhibit/prevent brute-force login attempts? Thx. Rick Rick Steeves http://www.sinister.net "The journey is the destination"

We''re testing out the Puppetlabs-Firewall module. And it seems I''m either missing something fundamental or Logging/Accpet works/doesn''t work in an irregular way. I would be most grateful for some input. *COMMON:* firewall { ''002 accept related established rules INPUT'': proto => ''all'', state =>
