Since a few weeks the CSF Real time blocklists checker in WHM stopped working. The titles of the hourly checks that email me, they report this:

`RBL Check on server04.ourcompanydomain.com: failures`

Every single list is failing, and I have no idea where to start checking why.

The only clue I have and the only text that seems out of order is in the middle of the email report Senderbase:...

Hi. I've been using CSF for a while on a PVE (LXC) server.
The host has an interface vmbr0 for public address and a vmbr10 that we use as an internal network (10.0.X.X)
Most LXC containers only have one of the internal network address as we use a Nginx proxy in one of them to receive all the external traffic. This to the local containers is an eth0 address. Additional IPs are routed through the...

Hi guys,
I'm new to csf, so, please dont judge me hard if already have answers.
Could you please help me understand how to build me owr rules.
As many users we run WP sites and most attacks are over login.php and xmlrpc.php.
So, how to tell:
If xxx.xxx.xxx.xxx POST (GET) login.php (and/OR xmlrpc.php) then check this IP in csf blacklists and if is there ban it perm (temp)

This example will help...

Hi there Folks

CXS is still a mystery to me so, while I'm slowing getting to grips with it being on our servers, could someone advise what to do with this?

I get these messages everyday from CXS from various of our servers. Do I...

Hello,

I was wondering if anybody has any insight into this issue we are seeing. We have centos6 and csf with cpanel integration installed. Sometimes a users IP will be blocked, and after being removed, the hostname will still remain blocked in iptables.

After trying to remove the block through CSF it's saying it doesnt exist:

Unblock 184.153.XXX.XX, trying permanent blocks...

Good morning CSF Team!

We are currently evaluating if we can use CloudLinux's Imunify360 solution which has a CSF Integration mode.

In Imunify360, when it detects CSF blocked an IP, it will move that block from CSF to Imunify360, however it relies on the 'BLOCK_REPORT' function of CSF.

During our testing, we've noticed that sometimes CSF will block an IP but Imunify360 didn't see the block....

Hello

I have two related questions if you could answer, I would be very grateful;

1) I am using Mod security as well as CSV on my Apache Centos server. I have been getting some IPV6 attacks and mod security is adding them to the mod security block just fine - but how can I manually add the offending IPV6 address into CSF? For example this one: 2a03:6f00:1::5c35:601e - when I try to add it I get...

Hello,

I am having issues with CSF not loading iptables rules on CentOS 8 on reboot. I have to run csf -r to apply the rules after reboot. How can I fix this?
