fail2ban ban not working
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

fail2ban help
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:

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

Fail2Ban Centos 7 is there a trick to making it work?
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.

fail2ban behavior
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

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:

fail2ban Asterisk 13.13.1
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+

anyone care to helop with a fail2ban problem on Centos 5.8?
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:

port = ssh

logpath = /var/log/auth.log
maxretry = 6

iptables - how to block established connections with fail2ban?
I am working to a CentOS 6 server with nonstandard iptables system

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

change destination on digit
Is there an easy way to setup diaplan so when someone pushes a digit such as
* during a call, they will be transferred to another destination.
For example, a caller is hearing ringing while calling a UA, but instead of
waiting for the UA to pick up, they can push * and go directly to that UA's
voicemail.
