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 -

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

Hello, fail2ban does not ban offending IP. NOTICE[29784] chan_sip.c: Registration from '"user3"<sip:1005 at asterisk-ip:5060>' failed for 'offending-IP:53417' - Wrong password NOTICE[29784] chan_sip.c: Registration from '"user3"<sip:1005 at asterisk-ip:5060>' failed for ?offending-IP:53911' - Wrong password systemctl status

If this is a small site, I recommend you download the free version of SecAst (www.telium.ca <http://www.telium.ca> ) and replace fail2ban. SecAst does NOT use the log file, or regexes, to match etc.instead it talks to Asterisk through the AMI to extract security information. Messing with regexes is a losing battle, and the lag in reading logs can allow an attacker 100+ registration

I've got an up-to-date Centos 5.8 and can't seem to get fail2ban to get rid of troublesome sshd login attempts. /etc/fail2ban/jail.conf has these sections: [ssh] enabled = true port = ssh filter = sshd logpath = /var/log/auth.log maxretry = 6 # Generic filter for pam. Has to be used with action which bans all ports # such as iptables-allports, shorewall [pam-generic] enabled =

Hi, I realise that one can simply start fail2ban and then it will insert its own ruleset before shorewall''s ruleset. Are there subscribers to this list having alternative (and probably better) ways to use both fail2ban and shorewall?

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 --

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

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
