Hello List, with CentOS 7.2 it is not longer possible to run fail2ban on a Server ? I install a new CentOS 7.2 and the EPEL directory yum install fail2ban I don't change anything only I create a jail.local to enable the Filters [sshd] enabled = true .... ..... When I start afterward fail2ban systemctl status fail2ban is clean But systemctl status firewalld is broken ? firewalld.service -

...stall fail2ban"? This installs fail2ban and fail2ban-firewalld. 2: install /etc/fail2ban/jail.local.? This file enables the matching rules in /etc/fail2ban/filter.d/sshd.conf, and allows up to 10 failures. ??? [sshd] ??? enabled = true ??? maxretry = 10 3: install /etc/fail2ban/action.d/firewallcmd-ipset.local.? This file overrides the default action defined in /etc/fail2ban/action.d/firewallcmd-ipset.conf and selected in /etc/fail2ban/jail.d/00-firewalld.conf.? The new definition blocks the source address from *all* TCP ports rather than just the ports defined for the jail (in /etc/fail...

Hello Experts! I'm sure many of you run CentOS for some time already. My question is: is there some place that lists which of the most often used sysadmin commands are gone and what are replacements for them. Or what else one needs to do after successful installation. (in the past it was process accounting that was not enabled by default, but which gives you quite some handle in

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.

...a clean test install. [root at centos7 fail2ban]# rpm -qa fail2ban\* fail2ban-sendmail-0.9.3-1.el7.noarch fail2ban-firewalld-0.9.3-1.el7.noarch fail2ban-0.9.3-1.el7.noarch fail2ban-server-0.9.3-1.el7.noarch Make sure you have fail2ban-firewalld installed as this provides the configuration to use firewallcmd-ipset as default banaction. Plenty of reasons for the "ERROR: NOT_ENABLED" logging, see man 5 firewalld.dbus. Alexander

...> The fail2ban-systemd package configures fail2ban to use systemd journal for log input. The OP can see that it is detecting the transgressions, so the input side of things is not the issue. What they appear to be having problems with is the banning process. Personally, I don't use 'firewallcmd-ipset' for banaction, I use 'iptables-multiport'. But the OP needs to look at what exactly is happening to the firewall configuration when an IP is banned. P.

I have just tried this, and re-started fail2ban. It does not seem to have worked. I have looked at /var/log/exim/main.log and found lots of lines like 2019-04-29 09:39:15 dovecot_plain authenticator failed for (hosting-by.directwebhost.org.)

My first impression was that firewalld and NetworkManager had a more desktop oriented/plug-n-play type feel compared to traditional

I am working to a CentOS 6 server with nonstandard iptables system without rule for ACCEPT ESTABLISHED connections. All tables and chains empty (flush by legacy custom script) so only filter/INPUT chain has rules (also fail2ban chain): Chain INPUT (policy ACCEPT) target prot opt source destination f2b-postfix tcp -- 0.0.0.0/0 0.0.0.0/0 ACCEPT all --
