similar to: Fail2Ban & CSF

Just to add another alternative while we're discussing the subject, I've got a soft spot for CSF as a replacement for fail2ban, and it has a lot of additional features as well. https://www.configserver.com/cp/csf.html P.

Hi all I have a CentOS 5.1 server running Xen and recently installed ConfigServer Firewall (CSF) on the main node to give it some protection. On a daily basis I''m getting an email about portmap. haldeamon and xfs consumming too much resources. The main node, dom0 doesn''t even do anything, and everything is done on the domU''s Here''s a thread I''ve

I use SSHGuard on well ssh (doh!), but supposedly you can use it for postfix and dovecot also. I can tell you it is well supported. I am on Centos 7 using firewalld. ? Original Message ?

I find csf/lfd much easier to configure and can be used in combination with fail2ban.

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.

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

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: (?:Info: )?(?:Aborted

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 isn't output though showing any login attempts being restricted.

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 use /var/log/fail2ban now, that finally worked through logrotates and logwatch.

This should probably be a bug report for the fail2ban EPEL maintainer, the problem was introduced in version 0.9.3 >From the file /etc/fail2ban/action.d/iptables-common.conf ... # Option: lockingopt # Notes.: Option was introduced to iptables to prevent multiple instances from # running concurrently and causing irratic behavior. -w was introduced # in iptables 1.4.20, so

Just a random stab in the dark, but CEntOS6 was iptables, and CentOS7 is firewalld. They take different fail2ban packages. CentOS6 = fail2ban CentOS7 = fail2ban-firewalld Are you sure you are running the correct fail2ban package for your firewall? (I screwed this up myself before I noticed and fixed it...) Good Luck!
