Hi, I'm running CentOS 7 on an Internet-facing server. SELinux is in permissive mode for debugging. I've removed FirewallD and replaced it with a custom-made Iptables script. I've also installed and configured Fail2ban (fail2ban-server package) to protect the server from brute force attacks. Out of the box, Fail2ban doesn't seem to play well with SELinux. Here's what I

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! Thanks, John H. Nyhuis Desk: (206)-685-8334 jnyhuis at uw.edu Box 359461,

Hi, Some time ago I had SELinux problems with Fail2ban. One of the users on this list suggested that it might be due to the fact that I'm using a bone-headed iptables script instead of FirewallD. I've spent the past few weeks getting up to date with doing things in a more orthodox manner. So currently my internet-facing CentOS server has a nicely configured NetworkManager, and

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 [16138]: NOTICE [dovecot] Ban 77.40.61.224 2020-04-07 09:42:06,981

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

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 --

On a CentOS 6.7 system that's been running fail2ban for a long time, we recently started seeing this: ct 28 19:00:59 <servername> fail2ban.action[17561]: ERROR iptables -w -D INPUT -p tcp --dport ssh -j f2b-SSH#012iptables -w -F f2b-SSH#012iptables -w -X f2b-SSH -- stderr: "iptables v1.4.7: option `-w' requires an argument\nTry `iptables -h' or 'iptables --help' for

Is anyone using asterisk with fail2ban? I have it working except it takes way more break-in attempts than what is set in "maxretry" in jail.conf For example, I get an email saying: "The IP 199.204.45.19 has just been banned by Fail2Ban after 181 attempts against ASTERISK." when "maxretry = 5" in jail.conf Perhaps someone else is experiencing this or has resolved it,
