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 |...

I am testing the solr FTS following the guide here: http://things.m31.ch/?p=379 Now I am having problem when I try to test: # doveadm -v? index -u fail2ban at mydomain.com Inbox doveadm(fail2ban at mydomain.com): Error: fts_solr: Invalid XML input at 1:0: not well-formed (invalid token) (near: { ?

I've followed one of the pages on line specifically for installing fail2ban on Centos 7 and all looks fine. I've added a fail regex to /etc/fail2ban/filter.d/exim.conf as suggested on another page: \[<HOST>\]: 535 Incorrect authentication data which appears to be successfully matchnig lines in /var/log/exim/mail.log such as 2019-04-19 13:06:10 dovec...

Hi! I have a server running CentOS 7.7 (1908) with all current patches installed. I think this server should be a quite standard installation with no specialities On this server I have fail2ban with an apache and openvpn configuration. I'm using firewalld to manage the firewall rules. Fail2an is configured to use firewalld: [root at server ~]# ll /etc/fail2ban/jail.d/ insgesamt 12 -rw-r--r--. 1 root root 356 21. Jan 05:12 00-firewalld.conf -rw-r--r--. 1 root root 610 15. Nov 19:55 a...

Copy dovecot-pop3imap.conf to dovecot-pop3imap.local.? Edit dovecot-pop3imap.local and add to the failregex: dovecot:.+auth failed.+rip=<HOST> Then run: fail2ban-regex /var/log/dovecot.log /etc/fail2ban/filter.d/dovecot-pop3imap.local and see if you get any matches.

I got the fail2ban from epel. There were a number of issues relating to using a log file... logwatch was looking for both fail2ban and fail2ban.log logrotate file fail2ban added looked for fail2ban.log and then reset itself to syslog fail2ban itself went to syslog, over riding its fail2ban.log. took a while, but I...

Have you tried just using the the filter dovecot.conf come with the fail2ban? # cat /etc/fail2ban/filter.d/dovecot.conf ...... failregex = ^%(__prefix_line)s(?:%(__pam_auth)s(?:\(dovecot:auth\))?:)?\s+authentication failure; logname=\S* uid=\S* euid=\S* tty=dovecot ruser=\S* rhost=<HOST>(?:\s+user=\S*)?\s*$ ^%(__prefix_line)s(?:pop3|imap)-login: (?:I...

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 will be a pr...

Been working on fail2ban, and trying to make it work with plain Jane install of Centos 7 Machine is a HP running 2 Quad core Xeons, 16 gig or ram and 1 plus TB of disk space. Very generic and vanilla. Current available epel repo version is fail2ban-0.9.1 Looking at the log file, fail2ban starts and stops fine, there i...

I have fail2ban on my mail server monitoring Dovecot and Exim. I have noticed that it has stopped banning IP's. I have seen in /var/log/fail2ban.log: 2020-04-07 09:42:05,875 fail2ban.filter [16138]: INFO [dovecot] Found 77.40.61.224 - 2020-04-07 09:42:05 2020-04-07 09:42:06,408 fail2ban.actions...

Apologies, this is slightly off-topic being to do with an EPEL package, although it's running on CentOS6, so I thought others here might have come across this issue. I have five CentOS 6 systems running fail2ban from EPEL, and this package was updated in the last week from 0.9.2-1.el6 to 0.9.3-1.el6. On all these systems, I received an error from logrotate this morning. It appears that something has broken the flushlogs option in fail2ban-client: [root at system ~]# cat /etc/logrotate.d/fail2ban # # Gen...

I recall others on this list are using fail2ban to block brute force login attempts. Packages are from the EPEL repo, so I'm just sharing some knowledge here. For about two months now I've had a CentOS 6.3 box (web host) in production that occasionally is ftp brute forced. Oddly enough fail2ban wasn't nabbing the perpetrators. I fo...
