A user submitting the wrong login details to the mail service or htaccess login can easily result in their IP address being added to the CXS reputation list. Their access to the server will be blocked, and access to other servers using CXS reputation list.

When a user reports the problem, the first thing we do is search for & remove the IP address in CSF (as I presume most server admins will...

We have been using CSF on cPanel quite successfully for years and over the last couple of years, we have started using them on Virtualmin/Webmin servers as well. The difference we see is that while CSF is very well optimized for cPanel with lot of additional custom configuration like monitoring unwanted scripts, monitoring exim login attempts and blocking them if necessary, monitoring service...

Hello,

my /usr/local/cpanel/logs/login_log is full of failed whm login attempts from ip addresses in verry strange countrys but it looks like the attackers know the defending mechanism against this type of attack because they stop after two failed attempts and a few hours hours later they try again.

I know this would be a working as designed status as my LF_CPANEL is set to 5 so it only...

Is the intended behavior that csf /lfd will only email upon the first WHM root access from the same IP within so many hours?

I'm trying to figure out why lfd only sent one email WHM/Cpanel root access alert when I logged in and out and then in again a few times to WHM. The cpanel login_log shows all three WHM logins, but lfd only emailed once and only logged the first whm login to...

I've run into this before at I swear sometimes the set loads, sometimes it doesn't. I feels like it happens more often when I add a new blocklist.

Here's my config:

FIREHOL2|3600|0|

FIREHOL3|3600|0| /blocklist-ipsets/master/firehol_level3.netset

We would to allow IPs from a FQDN with multiple A records, for example out.adyen.com, which resolves 20 different IPs.

Will this work? Is there a specific way to configure this?

Thanks in advance.

whoops... silly error. I was placing my ignore commands under IP Blocking rather than process blocking ... completely missed the drop-down list of ignore options.

Hello

I would like to activate the access limit for each IP, for example, to allow 5 requests per second for one IP

Hi there. Lately I was getting a lot of errors like
*Error* pid mismatch or missing, at line 1160
daemon stopped
This error is caused by trying to block some IP address, which triggered csf of lfd rule few times in a row. After that csf is disabled, but it was reenabled by cron job, which monitors services state

This is from lfd.pl (including line 1160, where an error is triggered)

Hello,

we have a server that needs to be able to access mysql with the root user.

We have blocked port 3306 globally.

And allowed the authorized IP in csf.allow with the following format:

We check that it works fine, but we have found a strange log:

We tried to install csf on a server running the Ubuntu 18 system and you blocked countries from accessing the server
But it appears that the server works in countries that have been blocked

dpkg --configure -a

2-===========

cd /usr/src

wget
tar -xzf csf.tgz
cd csf
