I just got 14 messages all stating that my account logged onto root. But that wasn't me. I quickly logged on and checked and see no evidence of any root logins.

Suspecting that these might be older messages just now coming in (from previous days) I checked the email headers and they show that they came in just a minute ago. The /var/log/exim_mainlog also shows that the messages were just sent....

Hi all,

I have a Debian 9 server with all the latest patches and CSF/LFD the latest version. Just a standard configuration with one IP number, no crazy things.

I want to automatically block IPs when they try to break in. I thought CSF/LFD did out of the box, but still I wake up with 600 of the below alert mails:

HI all ,

Dear all,

I just setup CSF.

My home network works within 192.168.178.0/24 .
My plan was to only (mainly) allow internal connections to and from the server on which CSF has been installed.

Therefore I started with adding 102.168.178.0/24 to csf.allow:

Hi

I've read through quite a few posts on this forum and no one else seems to have the issue I'm having. I can't even get csf to register the postfix sasl attacks.

Hi there,

I have enabled login failure protection but it is letting a lot of attempts through:

Hi,

We are currently testing messenger with reCAPTCHA activated to allow our customer to unblock their IP when blocked.
So far, the HTML service is running and we are able to get the web page.
The reCAPTCHA is able to validate if the visitor is a bot or not but for some reason, once reCAPTCHA has been validated, the IP still remains blocked even tho we are seeing the following message:

Hi all,

In WHM when the CSF Firewall is enabled and Backups are triggered, there is a huge amount of softIRQs triggered (see screenshot at the bottom). When disabling the CSF Firewall: those softIRQs are a lot lower.
We have other servers elsewhere (VPS, not dedicated) and while there are some softIRQs, it is not as much as the screenshot attached.

I have made sure that the server is running...

Hi to all
please i need your help as what is happening is impossible

I have a server with csf (as all of us here...)..

All the sites stop loading after some time from SPECIFIC IPs that login to WHM or wordpress admin..

So if x person is working on this site to make it, after some time he looses access as csf blocks him.

The same from the corporate network, probably after much conections its...

Hi Guys,

I'm trying to setup a custom regex for nextcloud login failure detection. It is not working (triggering when I try to login >5 times with incorrect credentials):

I have setup /var/www/nextcloud/data/nextcloud.log as CUSTOM1_LOG. lfd says it is watching the file, and entries look like this:

Hi all,
It might be that Christmas is coming and my brain is more focus on Santa stuff instead of being able to read and understand the instructions, or that I am just TAU (tired as usual).

My problem is that I can't figure out if LF_INTERVAL is doing one or 2 things:
1) limiting the number of triggers accepted during the LF_INTERVAL number of seconds
2) setting the time between checks
