I have 2 VPS both managed by WHM-cPanel
One of them is very old and works fine, while new one just installed Centos7 and cPanel.
On both VPSs run same CSF v14.08.
I am facing a strange bug on the new VPS cPanel installation.
The TCP_IN: List is not applied at all
That means, what ever port i add to this list, does not open.
The List that the i get from the View Listening Ports button, has nothing...

Hi. We'd like to only allow FTP access to users who connect via a specific hostname like: portal4321.vps22.hostingserver.com.

And block everything which tries to connect to the FTP in a different manner, like ones who use the server IP or vps22.hostingserver.com directly.

Is this possible in CSF? If yes, great, how do i set it up?

Thanks!

I'm guessing this is a modsec question, but please let me know if I'm in the wrong place.

We have the problem of hackers trying to submit forged payment requests. They return the url /checkout?payment_failed=1 when their attempts fails.

How can we block their ip IF they visit that url more than 3 times?

Many thanks in advance.

Hi.

After upgrading machines that uses CSF to cPanel v92, this notification started coming every second:

lfd on host.domain.com: SUDO login alert - Successful login from wp-toolkit to root

Setting Account Tracking to root or even disabling it seems not to work.

The binary has been whitelisted in pignore.

What could be done to stop this notification as it clogs the pipeline and eats up email...

Hi I am trying to configure lfd Clustering in csf, however the fields are all gray outed and unable to fill any number.
I use cPanel + immunify360.
Has anyone overcome same issue? :confused:

I have an email address that is repeatedly checking my server, but that account is invalid (non-existant account), and I know that the person doing it is not malicious, but only stubborn for not updating their settings, can i skip that email address from being checked by CSF and dont block their IP?

I use directadmin by the way.

Good morning,

Is there a way to rate limit efficiently cPanel account with daily limits with ConfigServer Mail Queue ?

In csf.conf I have
LF_IPSET = 1
LF_IPSET_HASHSIZE = 1024
LF_IPSET_MAXELEM = 65536

I have several public blocklists enabled, namely ABDE, BDEALL, SPAMDROP, etc., all of which have been working correctly on csf with ipset for several years. At this point, I don't recall precisely what I had to do to set it up initially. I thought all I did was uncomment a line in /etc/csf/blocklists to enable...

Good morning,

Is there a way to check if From header matches authenticated user and block via MailScanner or OSM if it is not matching?

Thanks in advance.

I have private custom ipset-managed blocklists on my system that get wiped out whenever csf is restarted,because, of course, csf is unaware of them. This poses a management problem.

Is there some way to inform csf of the existence of these ipsets? I am only aware of the support in /etc/csf/csf.blocklists, which is geared entirely to public lists dowloaded from external URLs.

The kind of...

Hello Everyone,
Does anyone know if CSF process is monitored by Cpanel server manager? As some mornings i find CSF randomly stopped i want to make sure that the service restarts should this happen?

Thanks

Am I getting the error below after last update, anyone else?

UPGRADE:

I enabled LF_IPSET and WAITLOCK, but it didn't work.

Hello,

my server provider blocked 25 port, and I use external SMTP service for all outgoing mails. is there someway to setup CSF to send mail notifications via external smtp with required autorization? Thanks!

I am trying to standardize my servers better with Puppet. Puppet is very good at building files with multiple lines like csf.allow, but it is more difficult to add multiple values to a single line like the TCP_IN list in csf.conf.

I attempted to add partial lines to csf.allow, but that didn't seem to work:
tcp|in|d=22 # puppet - from csf-global-allow-ssh
tcp|out|d=8140|d=192.168.118.31 # puppet...

Getting this on check:

Server Check
Check SUPERUSER accounts
You have accounts other than root set up with UID 0. This is a considerable security risk. You should use su, or best of all sudo for such access

How do I check what users have that permission and how do I correct that?

Hello,

Last couple days the LFD on some of my servers have gone a bit crazy. 60+ M/s sustain disk write.

If I turn off LFD Disk IO goes down to almost zero.

I start LFD and it spikes right back up.

I'm struggling to figure out what LFD is doing that's taking so much IO so I can try and fix the root problem.

Thanks.

Hello,
I have had a relatively serious problem for a few days. I have a VPS and I am suffering an attack, almost daily, which I think is DDOS, many connections from different IP's.
I have lowered the value of CT_LIMIT and this is mitigating the attack, but as I lower it, they lower the number of connections per ip and increase the ip's.
I had to get the CT-LIMIT value down to 5 (for a few...

Hi there

We have an server with

CT_SUBNET_LIMIT= 350

however, we do not want this to affect a particular subnet eg 192.168.1.0/24

Immediately, as expected 192.168.1.0/24 triggers

csf -t

hi all,
I have wordpress on two web server nodes behind a loadbalancer server. and I log failed login IPs on web nodes in a file in order to use this custom regex on it:

if (($globlogs{CUSTOM1_LOG}{$lgfile}) and ($line =~ /^(\d+\.\d+\.\d+\.\d+)/)) {
return ( Failed Wordpress login from ,$1, wordpresslogin , 5 , 80,443 , 3600 , 0 );
}

this works on both servers. But I figured out this is...

Hi,
Our clients OFTEN get blocked by CSF/LFD due to mail bad login attempts, or stuff like that.

They are in offices with multiple email clients (outlook or other).
They always tell me that they did not change anything.
But it MIGHT be one of their employees with an iPhone misconfiguring their account.

So I would like to give them MORE information about WHICH device in their network is making...
