similar to: CentOS 6.3 - fail2ban not working properly + workaround

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

We're seeing on a few of our servers - and sometimes it's only occasionally on some of those - where fail2ban's running happily, AFAIK, but there's an attack (from China, Brazil, etc) on ssh, and they don't seem to be banned; I see many, many sorries for wrong username or password. It *seems* to work again once restarted. mark

Hi has someone a script which can filter out dictionary attacks from /var/log/maillog and notify about the source-IPs? i know about fail2ban and so on, but i would like to have a mail with the IP address for two reasons and avoid fail2ban at all because it does not match in the way we maintain firewalls * add the IP to a distributed "iptables-block.sh" and distribute it to any

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,

Hi, Is there any way to disable the "dovecot: " at the beginning of each line of the log? Fail2Ban responds poorly to it. I know there are a number of sites with "failregex" strings for Fail2Ban and Dovecot, but I've tried them all, and they don't work, at least with the latest Fail2ban and the latest Dovecot. The Fail2Ban wiki is pretty clear about why there

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 got the fail2ban from epel. There were a number of issues relating to using a log file... logwatch was looking for both fail2ban and fail2ban.log logrotate file fail2ban added looked for fail2ban.log and then reset itself to syslog fail2ban itself went to syslog, over riding its fail2ban.log. took a while, but I use /var/log/fail2ban now, that finally worked through logrotates and logwatch.

Hello, I have a big problem with fail2ban and firewalld on my new system. I have a server running (CentOS 7.1) and run a Update to 7.2 on this system all is working ?

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

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

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 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

I have tried to setup fail2ban on a machine running OpenSuSE 11. Everything looks fine, except the machine restarts the firewall whenever the DHCP lease is renewed, thus flushing all the fail2ban rules (I think.). It seems to me that a quick fix would be to have the system restart fail2ban whenever the firewall is restarted. Has anyone else encountered this issue? .and come up with a solution?

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'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 =
