ConfigServer Community Forum

I'm using this rule I pulled from the forum:

# BLOCKING LiteSpeed attacks by Sergio

if (($lgfile eq $config{CUSTOM4_LOG}) and ($line =~ /^\S+\s+\S+\s\ .*Failed Login Attempt \- username: (\S+) ip: (\S+)/i)) {
return ( $1 ,$2, SECMAS_LiteSpeed , 1 , 1 );
}

on my cPanel/Linux box. In CSF.conf, I have

CUSTOM4_LOG = /usr/local/lsws/admin/logs/error.log

and a sample log line is

It seems LFD outputs its blocked messages (eg. Firewall: *UDP_IN Blocked* IN=eth0... ) to the system journal with priority 4 (warning), even when it's just blocking incoming traffic based on port number. This makes them gold-coloured in my TTY, but more annoyingly it gets spammed out to my VPS's emergency console standard output, putting out lines every few seconds. Is there a way to get LFD to...

Hello,

I am getting weird block mails everyday from ldf.

The title of the email is:

lfd on : :: (Unknown) blocked permanently

And the content is:

IP: :: (Unknown)
Temporary Blocks: 48

Temporary blocks that triggered the permanent block:

Hi there,
After the latest cpanel update to version 122.0.5 we have all of sudden been getting lfd email every hour as such:

hi

CSF having an IP detection error. It is actually from Colombia, but it detects it as Romania

Query:

A) What database does CSF work with to query IP and country of origin?
B) How can you update the CSF IP database?
C) Is there a way to report this type of IP location errors?

Thank

Hello,

I get this email from my server:
Subject: Cron /usr/sbin/csf -u
Message: csf and lfd have been disabled, use 'csf -e' to enable

I logged in to WHM to enable again all connection become blocked, if I disable via SSH everything works fine.
I can't image what I have to do to work again, should I reinstall csf or how can I find the problem?
I did not changed anything for weeks, csf updated 5...

When CSF blocks an IP, it shows all the information of where and why including the country code. I'm not sure where CSF gets the country code information but why can't you simply block by the country code instead of huge lists of CIDR's? I am able to do this in Modesecurity but I would rather block for the entire server instead of just http.

Example block list:
218.155.106.83 # lfd:...

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,

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
