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.

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 -

I recall others on this list are using fail2ban to block brute force login attempts. Packages are from the EPEL repo, so I'm just sharing some knowledge here. For about two months now I've had a CentOS 6.3 box (web host) in production that occasionally is ftp brute forced. Oddly enough fail2ban wasn't nabbing the perpetrators. I found that the iptables chain for VSFTP isn't

I'm trying to setup and test fail2ban with dovecot I've installed fail2ban, I've copied config from https://wiki2.dovecot.org/HowTo/Fail2Ban, and, trying to test it, attempted multiple mail access with wrong password, but, get this: # fail2ban-client status dovecot-pop3imap Status for the jail: dovecot-pop3imap |- Filter | |- Currently failed: 0 | |- Total failed: 0 | `- File

Hello, Has anyone got fail2ban working and blocking ssh spambot atempts? My ssh is logging with a facility of authpriv which syslogd sends to /var/log/secure. That file has 600 permissions owned and group of root. I want to make it where fail2ban can access the needed file, yet not make it insecure in the process. I was not wanting to change permissions last time I did that on a log file a cron

Hi, To begin I'm sorry for my poor English level, that's not my first language. On CentOS 6 I've installed fail2ban 0.8.4 from EPEL repository. I've configured it with this page : http://centoshelp.org/security/fail2ban/ Then I've tried this command : chkconfig --level 23 fail2ban on && service fail2ban start but the output says it fallen, nothing more. The status

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

Tonight I added fail2ban to one of my webservers to test it out. Here is my step by step, as best as I could figure it out...documentation a bit sketchy. feel free to add anything to it or suggest changes. I tried to set it up to deal with ssh, http authentication, dovecot, ftp, and postfix I could find no working example for centos 6 and there is no fail2ban book available to peruse. So,

I'm trying to set up fail2ban with dovecot, I have it working on 'old' server Centos 6, but, not getting anywhere with 'new' server on Centos 7 using standard filters I've copied same 'filter' to new server, still get nothing any idea how to figure this out ? on old server, it logs to syslog/messages CentOS release 6.10 (Final) dovecot 2.3.10.1 (a3d0e1171) old #

Hello list I'm trying to setup fail2ban specially sasl action but I'm facing problems. I have centos-release-5-9.el5.centos.1 and fail2ban-0.8.7.1-1.el5.rf installed with selinux disabled The errors I get are: INFO Creating new jail 'sasl-iptables' fail2ban.comm : WARNING Invalid command: ['add', 'sasl-iptables', 'polling'] I tried gemin against

Hello list. I have a question for fail2ban for bad logins on sasl. I use sasl, sendmail and cyrus-imapd. In jail.conf I use the following syntax: [sasl-iptables] enabled = true filter = sasl backend = polling action = iptables[name=sasl, port=smtp, protocol=tcp] sendmail-whois[name=sasl, dest=my at email] logpath = /var/log/maillog maxretry = 6 and the following filter:

I'm using fail2ban with CentOS 6.6. Something is causing fail2ban's alerts sent to root's mail to be rejected.

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?

I created a filter and verified it with fail2ban-regex against actual lines in my log and it works. During restarts of fail2ban, only some previous ip's get banned immediately whereas some need a reoccurrence despite the jail's config specification of maxretry and findtime suggesting the entries mandate blocking. I'd assume the behavior after a restart is noe way if it weren't for
