iptables - how to block established connections with fail2ban?

CentOS 7, Fail2ban and SELinux
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

CentOS 7 : SELinux trouble with Fail2ban
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

fail2ban firewalld problems with current CentOS 7
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

Mine occurred in Feb when my versions of firewalld etc were updated to the versions you show. Thus far I have not had the opportunity to sort the problem.

Nasty Fail2Ban update for Centos 7
Hi all... Recently a new Fail2Ban was available among some other updates for my Centos 7 system, and I just updated all. It seems that was a very BAD idea. Just noticed that Fail2Ban have generated a 6MB error log because of the update, and FirewallD a 1MB log of errors ! (not sure if any of those were really working after this) ok, I'll just run yum downgrade fail2ban I thought. Naa, no

asterisk and fail2ban
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,

svm in e1071 package: polynomial vs linear kernel
I am trying to understand what is the difference between linear and polynomial kernel: linear: u'*v polynomial: (gamma*u'*v + coef0)^degree It would seem that polynomial kernel with gamma = 1; coef0 = 0 and degree = 1 should be identical to linear kernel, however it gives me significantly different results for very simple data set, with linear kernel
