Been working on my anti-spam centos mailserver for a while now and thought I would share fail2ban's help. I installed fail2ban a few weeks back. It was tough to get it working properly but pretty much working now. Although it works fine for brute force, I thought I would run it pretty tough against spammers. I started with a regular mail server, my old one, that is horrendously pounded

Many of you are interested in and have used or recommended fail2ban for your linux boxes. I finally installed it on our FreeBSD server (no asterisk, hence the OT) with the help of a friend from the VoIP Users Conference and Asterisk community. After a lot of new learning about regex, I extended the actions and filters to look at our mail server, plagued by spammers - who isn't? Our server has

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.

Apologies, this is slightly off-topic being to do with an EPEL package, although it's running on CentOS6, so I thought others here might have come across this issue. I have five CentOS 6 systems running fail2ban from EPEL, and this package was updated in the last week from 0.9.2-1.el6 to 0.9.3-1.el6. On all these systems, I received an error from logrotate this morning. It appears that

Copy dovecot-pop3imap.conf to dovecot-pop3imap.local.? Edit dovecot-pop3imap.local and add to the failregex: dovecot:.+auth failed.+rip=<HOST> Then run: fail2ban-regex /var/log/dovecot.log /etc/fail2ban/filter.d/dovecot-pop3imap.local and see if you get any matches.

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

Have you tried just using the the filter dovecot.conf come with the fail2ban? # cat /etc/fail2ban/filter.d/dovecot.conf ...... failregex = ^%(__prefix_line)s(?:%(__pam_auth)s(?:\(dovecot:auth\))?:)?\s+authentication failure; logname=\S* uid=\S* euid=\S* tty=dovecot ruser=\S* rhost=<HOST>(?:\s+user=\S*)?\s*$ ^%(__prefix_line)s(?:pop3|imap)-login: (?:Info: )?(?:Aborted

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?

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.

If there is a serious power failure, eg during an electric storm, and the internet goes down then my CentOS-6.2 server seems to take an inordinate time, maybe forever, to get past fail2ban. It is as though there is an extremely long - maybe an hour - timeout if fail2ban cannot connect to the internet. (I usually stop the machine with the power-button, re-boot into a different OS (Fedora) and

This should probably be a bug report for the fail2ban EPEL maintainer, the problem was introduced in version 0.9.3 >From the file /etc/fail2ban/action.d/iptables-common.conf ... # Option: lockingopt # Notes.: Option was introduced to iptables to prevent multiple instances from # running concurrently and causing irratic behavior. -w was introduced # in iptables 1.4.20, so

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?

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
