Hello,
After upgrading from Ubuntu 22.04 to 24.04, and while CSF+ProFTP server was working fine, now it doesn't allow to retrieve directory listing.
Any suggestions ?

Hello ,
I created a custom modsec rule that returns a 403 status code if there is a sql injection attempt, i want csf to block the ip that is triggering this rule by monitoring the log that modsec is logging in it , but it isnt blocking it at all
the log came up as either
/usr/local/apache/error_log or
/var/log/apache2/error_log

so in csf.conf i specified the MODSEC_LOG to be...

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:

Time: Wed Sep 11 06:44:40 2024 +0300
IP: :: (Unknown)
Temporary Blocks: 48

Temporary blocks that triggered the permanent block:

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...

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 dear community.
I wanted to ask if ConfigServer ModSecurity Control support LiteSpeed Web Server and Imunify360?

Hello,

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

Failed to open : Permission denied

My csf.conf:

MESSENGERV3 = 1

MESSENGERV3LOCATION = /etc/apache2/conf.d/

MESSENGERV3RESTART = /scripts/restartsrv_httpd

MESSENGERV3TEST =

MESSENGERV3HTTPS_CONF = /usr/local/apache/conf/httpd.conf

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...

Hello everyone

Recently I'm receiving a lot of logs regarding spamd.
Do I need to worry about this?

Hello Guys,

I'm new to firewall/server configurations and I have a PCI scan result saying:

Your firewall policy seems to let TCP packets with a specific source port pass through.

Some types of requests can pass through the firewall. The port number listed in the results section of this vulnerability report is the source

Hi,

We have the following issues with Almalinux any suggestions?

# perl /usr/local/csf/bin/csftest.pl

Wondering if someone could explain how Mailscanner handles contact forms?
Probably a dumb question but I didn't find an answer from my searches.
Have been seeing an increase of copy paste stuff into contact boxes on some sites and wondering if using Learn as Spam would affect all the contact forms sent or just the content of the forms ?

Hi,

I'm encountering something I've never seen before. This is on a newish server running AlmaLinux v8.10.0 STANDARD standard
cPanel Version 120.0.14, with the full ConfigServer server package installed when it was brought online. When I check CMQ, it shows two messages in the queue for 92 days. CMQ seems to allow me to delete the messages, but they never actually delete. If I try to get details...

Greetings, within /etc/csf/lfd.pl, we have this little tidbit of code within the getlogfile section (between lines 2194 to 2248).

my $text = *Error* Log line flooding/looping in $logfile. Reopening log file ;
logfile( $text );
if ($config{LOGFLOOD_ALERT}) {
my @alert = slurp( /usr/local/csf/tpl/logfloodalert.txt );

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

The default CSF configuration files allow UDP in/out ports 20 and 21:

UDP_IN/UDP6_IN = 20,21...
UDP_OUT/UDP6_OUT = 20,21...

I believe this is a mistake. The FTP RFC defines it as a TCP-only protocol.

We were also unable to locate any implementation of ports 20,21/UDP in the field.

Viewing in WHM> ConfigServer Security & Firewall - csf v14.20 and it says enabled and also confirmed in lfd.log but it references mod_cloudflare which is no longer supported, so I'm using mod_remoteip. Is this integration still working? If so, how to verify?

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
