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 copied jail.conf and added the edited jail.local to the directory /etc/fail2ban/
This is about as far as I have gotten with searches on how to configure with Centos 7.
Any help would be welcome. What am I missing?

This is what I have for ssh in jail.conf
[ssh-iptables]
enabled = true filter = sshd action = iptables[name=SSH, port=ssh, protocol=tcp] sendmail-whois[name=SSH, dest=x@harte-lyne.ca, sender=x@harte-lyne.ca, sendername=Fail2Ban] logpath = /var/log/secure maxretry = 5
I’m using fail2ban with the -firewalld and -systemd modules, and I had to setup some SELinux rules to make it working right. This is the policy I add to the CentOS 7 machines:
module fail2ban-journal-sepol-new 1.0;
require { type fail2ban_client_exec_t; type logrotate_t; type fail2ban_t; type syslogd_var_run_t; class dir read; class file { ioctl read execute execute_no_trans open getattr }; }
#============= fail2ban_t ==============
#!!!! This avc is allowed in the current policy allow fail2ban_t syslogd_var_run_t:dir read;
#!!!! This avc is allowed in the current policy allow fail2ban_t syslogd_var_run_t:file { read getattr open };
#============= logrotate_t ============== allow logrotate_t fail2ban_client_exec_t:file { ioctl read execute execute_no_trans open };
What’s the best way to report the selinux problems in EPEL packages, btw?
