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

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

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 ~]#

So I have this nice, simple web server up running. Its purpose is to allow me external testing with HIP, and to provide some files for external distribution. Of course, there it is sitting on port 80 and the attacks are coming in per logwatch report. Examples from the report include: Requests with error response codes 404 Not Found //phpMyAdmin-2.5.1/scripts/setup.php: 1

Hi, I have a current auth database using mysql with a "password" column in plain text. The config has "default_pass_scheme = PLAIN" specified In preparation for a more adaptable system I changed a password entry from "asdf" to "{PLAIN}asdf", but now auth fails. Works fine if I change it back to just "asdf". (I don't believe it's a

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

Hi, Is there any way to disable the "dovecot: " at the beginning of each line of the log? Fail2Ban responds poorly to it. I know there are a number of sites with "failregex" strings for Fail2Ban and Dovecot, but I've tried them all, and they don't work, at least with the latest Fail2ban and the latest Dovecot. The Fail2Ban wiki is pretty clear about why there

Hello list. I have a question for fail2ban for bad logins on sasl. I use sasl, sendmail and cyrus-imapd. In jail.conf I use the following syntax: [sasl-iptables] enabled = true filter = sasl backend = polling action = iptables[name=sasl, port=smtp, protocol=tcp] sendmail-whois[name=sasl, dest=my at email] logpath = /var/log/maillog maxretry = 6 and the following filter:
