ConfigServer Community Forum

We are trying to block all incoming IPs and only allow cloudflare IPs. We've whitelisted this in csf.allow we still wanted to check if from CSF side if we can block all other traffic.

Hello Everyone :)

I hope you are well. I now manage numerous servers running WHM; and I have lately begun integrating config server security and firewall and login failure daemon to improve the security of these systems. While I have some familiarity with server management; I am new to the more advanced configurations and optimizations that CSF and LFD provide. I am seeking out this informed...

Hello,

After setup MESSENGERV3 when IP is blocked, return this error bellow on log, and show 404 page of Litespeed:

Hi.

On a machine with CSF (although on others the problem has appeared after writing this ticket)

It has been installed and running for years.
The settings are very restrictive. Only port of entry 53 is open, the rest are not.
Access is only allowed to my ips. One of them dynamic, added to csf.dyndns

Today I couldn't get in. So I logged into the server via KVM (it's a proxmox)

The first thing...

In order to sort (some) compatibility with Docker and CSF we are working on an approach to allow docker to handle its iptables adding a chain on prerouting added in csfpost.sh

The problem is that for this to work we need to store all docker generated chains on each csf restart and reload them in csfpost.sh

For my surprise, csfpre.sh is not executed first on that process. CSF first clears all...

Hi, we do not see any CSF email alerts in the exim_mainlog, and we aren't receiving any either. The server is also running cPanel and WHM. We have taken the following steps to check that everything is set:
Testing = 0 in the configuration
LF_ALERT_TO AND X_ARF_TO are set to the correct email
Alerts are turned on in the configuration
LF_EMAIL_ALERT is set to 1 or true
/etc/aliases root is...

Hello,

There are hackers trying to find vulnerabilities by testing every 2 seconds.
Response is 404 or 301. Sometimes also 403
Shouldn't CSF block that?

Hi all,
Is there a way to exclude one user (or few) from blocks in CSF?

How can we disable the passive mode that we had previously enabled as well as activate the SPI that we had disabled.
Thank you very much in advance for your help

Hi
I have a very bad problem , i put some ip in csf.allow and even in csf.ignore but they still blocked by firewwall.
can anyone help me?

Hi all,
Where does csf keep the list of blocked emails that are associated with IP address?
I remember on one of my previous csf installations I had the ability to see blocked emails and from which IP addresses these emails tried to connect but now I can't find it on this new server.

Hello, every 5 minutes I receive this email. What I can do ? You never did this before and the configuration is the same as when you did it several years ago, I have not modified anything since then

I have this problem, maybe you can help me. I am not able to upload files via FTP with CSF active. If I deactivate it I can upload without problems.

My FTP client is very old and has no options. It is part of custom software. It only connects without SSL and uploads files in ACTIVE mode. That's why I can't put it in PASSIVE mode, which surely works. I already have the range of ports open for...
