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+

Decoding SIP register hack
I need some help understanding SIP dialog. Some actor is trying to
access my server, but I can't figure out what he's trying to do ,or how.

fail2ban
For dovecot 2.1
as per wiki2, is this still valid? noticed a problem before and saw
it does seem to be triggering, I use:
maxretry = 6
findtime = 600
bantime = 3600
and there was like, 2400 hits in 4 minutes, it is pointing to the
correct log file, but I am no expert with fail2ban, so not sure if the
log format of today is compatible with the wiki2 entry

under another kind of attack
Hi to all,
@Olaf Hopp I've this filter enabled for fail2ban, my question is: could
my filters overlap or interfere with those suggested by you?
this is my filter:
Contents of /etc/fail2ban/jail.conf:
[postfix]
# Ban for 10 minutes if it fails 6 times within 10 minutes
enabled = true
port = smtp,ssmtp
filter = postfix
logpath = /var/log/mail.log
maxretry = 6
bantime = 600

Hello;
Did you remember to uncomment the dateformat in
/etc/asterisk/logger.conf? That's necessary for fail2ban to work.

dateformat=%F %T

under another kind of attack
Hi folks,
"somehow" similar to the thread "under some kind oof attack" started by "MJ":
I have dovecot shielded by fail2ban which works fine.
But since a few days I see many many IPs per day knocking on
my doors with wron password and/or users. But the rate at which they are knocking
is very very low. So fail2ban will never catch them.
For example one IP:

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:
