Hi,
LF_APACHE_404 not working on cPanel with litespeed.
HTACCESS_LOG is setup with /var/log/apache2/error_log but not working
I've inserted custom regex but no work.

Can you help me to build custom 404 regex on cPanel litespeed?

I have an issue because every day I receive from lfd information about overload my server and logs shows me many connections from Microsoft adress IP. Manual block IP isn’t good because every day is another IP. In Csf I have set two parameters: CONNLIMIT 80;50,443;50 i PORTFLOOD 80;tcp;100;60,443;tcp;100;6 but it doesn’t work. Could you give me any suggest how to resolve this an issue?

I apologize if this is in the wrong area.

On ModSecurity I switched the ruleset from Comodo to OWASP, and now LFD isn't sending the Mod Security notifications to email.

LFD is sending out emails for other notifications.
Have restarted CSF & LFD, and ran csf -ra

Any suggestions are welcome on what to look at.

Thanks

Hi,

I've recently setup the emails for csf/lfd and I started getting tons of emails coming through, but most of them appear to be false positives.

I've added the following rules to csf.pignore but they don't appear to be working as the emails for the very same reasons are still coming through even after restarting both CSF and even the entire server....

Hi,

I hope you can help.

Hello,

Due to some requirements, I can't use PT_USERKILL to kill process over PT_USERTIME / PT_USERMEM, I need to use custom script in PT_USER_ACTION to perform advanced checks.

However, I've seen that since I switched PT_USERKILL to 0, I keep receiving Excessive resource usage emails, no matter if PT_USERKILL_ALERT is set to 0 or 1.

How can I disable the Excessive resource usage email without...

Hello to CSF Community,

After migration to AlmaLinux 9 from CentOS 7 I suddenly met the problem with loading files by ftp (example from shell)

Hello,

I have a server that will be used for development tasks. So i want this server only accessible from Finland (for some ports only, all other ports will be blocked for anywhere). I tried lots of settings and couldn't make it working.

My configuration is below:

FASTSTART = 0

LF_IPSET = 1

MM_LICENSE_KEY = ABCDEFG12312

CC_DENY =

Hello

I have a few rules under regex.custom.pm.

Some are very important and I want to receive mail notification and other not so much so no need of notification.

Is there any way I can disable mail notifications for specific rules and keep temp/perm block working as expected?

It would also be cool if we can filter notifications by country.

Thank you

Hi - we're needing some assistance to get these type of attacks blocked automatically with a custom regex- say 10 login attempts in 12 hours to mitigate slow logins and permanently banned and added to block list where we can remove them if needed in case of customer false attempts. We've tried a few things including fail2ban although it would be great if LFD can scan the logs and ban them...

Hi,

We are getting lots of Process Tracking notifications for an executable and would like to add it to csf.pignore

/usr/local/cpanel/3rdparty/perl/536/bin/perl

What is the correct syntax to add this to /etc/csf/csf.pignore please?

Thanks very much

Hi, forgive me if this has already been asked and adequately answered, but I haven't found it so far:

I'm new to DirectAdmin and ConfigServer and trying to configure everything properly. I'm confused because the server security check keeps returning:

You should consider disabling commonly abused php functions, e.g.:
disable_functions = show_source, system, shell_exec, passthru, exec, popen,...

I've seen some posts about using BLOCK_REPORT to customize when an IP is blocked. I'm looking for something that will allow me to execute a custom script whenever CSF identifies accounts exceeding processes, mem, time limits. I want to be able to kill certain accounts (based on their web hosting plan) via a custom script that will allow me to do further reporting/stats at the same time.

Is there...

Hello people,

There are a lot of questions on this forum regarding this, and I have read most of them. As is usually the case, I am receiving a huge amount of notifications from CSF, from a cron.php that the user of this server has placed and wants to run every 5 minutes. This process is legit, and we want to keep it running. The output is this:

Executable:

/home/virtfs/...

OS: CloudLinux release 9.4 (Vladimir Vasyutin)
CSF version: csf: v14.21 (cPanel)

Hi,

I'm facing a strange issue where CSF is not blocking nor allowing IPs in Almalinux/CL 9.
If I add a temporarly allow like this, it creates an IPTABLES entry and it doesn't work (port 22 is not in TCP_OUT):

# csf -ta 12.34.12.34
ACCEPT all opt -- in !lo out * 12.34.12.34 -> 0.0.0.0/0

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 ?

Once an hour the load on one of our servers spikes big time. Normal load is barely above zero, but it spikes to loads over 100.0 for a minute or two then comes back down to normal.

When it spikes I always see these: processes, with the first one causing the load:

lfd - retrieving global lists
lfd - retrieving blocklists (waiting for list lock)
lfd - retrieving countrycode lists (waiting for...

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...

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

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

and a sample log line is
