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

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"

Hello list. I have a question for fail2ban for bad logins on sasl. I use sasl, sendmail and cyrus-imapd.

Hi all, If I may, one more question on this subject: I would like to create a fail2ban filer, that scans for these lines: > Jul 20 11:10:09 auth: Info: ldap(user1,60.166.35.162,<cDFXHbxUQgA8piOi>): invalid credentials (given password: password) > Jul 20 11:10:19 auth: Info: ldap(user2,61.53.66.4,<V+nyHbxU+wA9NUIE>): invalid credentials (given password: password) (as you can

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.

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

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 fail2ban working for EVERYTHING else except dovecot. I have tried using my own custom regex in conjunction with the regex on the dovecot.org site. Neither are picked up by fail2ban and I'm trying to use an imminent attack agaist dovecot, going on now, to my advantage to see when I get the right regexp. Here are my current ones: failregex = .*dovecot: (?:pop3-login|imap-login):

Hi all We have an Asterisk server that?s been running for a few years now without problems. We have IPTables running, as well as fail2ban and have followed all the security recommendations we have found. Every few weeks we get an attack that lasts about a minute or two, resulting in our AGI script being overloaded. What happens is that somebody seems to be trying to connect from our
