Recently I disabled WP-CRON for wordpress and started using CPANEL with WGET to replace it. I've started getting emails lfd on XXXXX: Suspicious process running under user . I found some instructions on where to go to tell CSF to ignore these in the /etc/csf/csf.pignore edit, but I'm unclear exactly how to do this. Here is what the LFD emails are showing:

Hi guys,

We have configured the alert template (/usr/local/csf/tpl/alert.txt) on multiple servers to send email to a particular email account

This has been working fine for a number of years.

All of a sudden on one server it no longer works. We are puzzled as to why this would be the case.

Any ideas?

Thanks
Sasha

I've always used CC_ALLOW_FILTER to block non-US IPs, but I recently began using Cloudflare and now all connections come from a Cloudflare IP! My server load has skyrocketed, so I don't think that CSF is able to block non-US IPs anymore.

I blocked them in Apache configuration, but I think that runs after CSF, too, so I'm still getting the Apache connection for each request. And I'm talking about...

We are warding off a country denial of service attack on a WHM Exim server that has been ongoing for around 1 week. The attack takes the form of 1000s of servers sending email to non-existing recipients on the Exim server, quickly overwhelming the Exim's server's connection count limit ` smtp_accept_max `. The default for Exim is 20 connections. The default for cPanel is 100 connections. In our...

I've seen a lot of threads related to using Cloudflare, but no answers :-( Hopefully this thread will be the exception!

I've always used CSF's CC_ALLOW_FILTER to block non-US IPs. But I started using Cloudflare in September, and now that all incoming IPs appear to come from Cloudflare I don't think that this is working.

I tried enabling CF_ENABLE, but nothing changed so I think there must be...

LFD is emailing me three times for all excessive SFTP usage. Not for other excesses.

I know I could add the SFTP executable to the pignore file but I want to receive these notifications.

How can I make it email just the once for each excess?

After making all needed updates in my Ubuntu 20.04 server and restarting it through WHM I was not able to access the hosted sites(they are not propagating) and I was not able to check for Ubuntu updates through apt-get update.
The configuration of the csf v14.20 was unchanged and before the restart it was working perfectly.
My port settings are the following:

Hi all,

On my VPS I use:
- WHM/cPanel v114.0.11
- CloudLinux v8.8.0
- Plug-in: ConfigServer Security & Firewall - csf v14.20

I am a beginner.

On my VPS I host several websites for others. Also, the VPS serves as a mail server.

Part 1:
I perform all management tasks for my VPS from 1 fixed IP address for example xxx.xxx.xxx.xxx.xxx. This IP address should never be blocked and all ports...

I have tried this in my regex.custom.pm to use with the output from the error log file line(s) below but it doesn't work.

The log file I have added as CUSTOM1_LOG returns the following when...

Any idea how to completely unistall CSF from my WHM? I followed the famouns instructions but nothing happens.

==============
cd /etc/csf
sh uninstall.sh

Thanks

Sorry I am sure this has been asked but i can't seem to find it. I have a server with multiple ( 16 ) ip addresses. What i want to do is open specific ports on specific ip address of that server so for example:
ip: xxx.xxx.xxx.xxx i want to open port 6697 but don't want that port open on ip: yyy.yyy.yyy.yyy

tcp|in|d=6697|d=xx.xx.xx.xx from what i understand would be like if i wanted to open port...

I am trying to configure csf to allow tcp and udp in and out on ports 1514,1515,5601 and 9200. After I save these changes in the csf.conf file, verify the changes have actually been saved and restart csf, the changes take effect for a few minutes to an hour and then the csf.conf reverts to it's default version by itself. This happens both when I do it from the terminal and when I use the UI to do...

Hi,

I would like to ask if there is a conflict in using ConfigServer Security & Firewall (CSF) even if we already have CloudFlare and Azure NSG. My understanding is that it will provide an additional security layer in WHM/CPanel, but our network admin has suggested not to install it due to a possible conflict. Any suggestions and recommendations are appreciated.

Thank you.

hi,
i have csf in centos7.9 with cpanel and when csf is enabled, host tracker cant ping ip server or any website,
when i disabled csf, everything is completely works fine,
so whats the problem?
in my all servers the problem is the same with csf.
* when csf is enabled, everyone can access their website or server but websites like host-tracker.com or check-host.net cant ping them with timeout error.

I've just gone through the process of upgrading from CentOS 7.9 to AlmaLinux using the cPanel elevate script and everything went through successfully.

However, since the upgrade CSF has stopped functioning.

I'm getting hourly alerts with the following errors:

Aug 12 11:10:12 server.rhdns.com systemd : Starting ConfigServer Firewall & Security - lfd...

Hello.

I'm having problems with outbound emails that contain links to images not displaying in the email unless I disable csf.

I can't imagine what setting within csf is causing this to happen, so:

1) where can I get a fresh install csf.conf file to compare it with and:
2) anyone have a clue why images would not display in this situation.

Thank you.

Hi there

Since a few weeks, 2 or 3, I started having a very strange issue.

The server cannot communicate on self (like doing a curl on it's own ip, or access an image from an url hosted on the same server).

I have 3 servers with the same os, same config, and only this one has the trouble.

Let's take an example of a php website that generates PDF, where in the pdf you have an image loaded by...

I have a new server running CloudLinux 8.8 and while csf starts, it gives the following errors at the end of the startup output;
