I'm having difficulty with getting SMTP auth failures detected by LFD. I believe this is partially due to Postfix on Ubuntu not reporting the rhost in the /var/log/auth.log file. Here's an example:
Hello.
When I activate cfs and Fail2Ban, Fail2Ban does not send me detailed information like the one I attached in the email. When I disable cfs it sends.
VPS Server virtualmin for ubuntu 22.04
This started happening and I am not sure what I am missing at the moment. csf.deny is now cleared and I have created an /etc/csf/csf.cloudfront.allow with their full range of IPs and included reference to it in the csf.allow and restarted but I am still seeing timeouts. As soon as I turn off csf, it loads right up. I have also made sure flooding options are disabled but still encountering this...
Hello , I'm getting this message in my email from the cron daemon: Oops: Unable to download: Can't connect to download2.configserver.com:443 (Connection timed out) . now 433 is open and I don't see the cron job in the cron job area of cPanel. I've whitelisted the config server IPs too in CSF. is there a cron job script i can add to the cron job lists in cPanel? Thank you for the help! :)
I have a member on the server that uses google ads. Google is reporting http 500 error for the url's, even though they work fine. They are saying their IP(s) are being blocked. I downloaded a list of all of their IP's and CIDR's (about 300) and added them to the whitelist by editing the allow list. But the problem is still there. I found that if an IP is in the deny list and I add it to the allow...
Hi,
yesterday I updated cpanel and centos on a couple of servers and, after that update, CSF CC_IGNORE is not working.
I had CC_IGNORE for my country working for a long time until yesterday and, after that update, all servers have this issue now.
I'm reporting a persistent issue I've been experiencing with ZeroTier connectivity when the CSF is active on my Linux system. Despite my attempts to configure the firewall to allow ZeroTier traffic, ZeroTier does not function as long as CSF is active.
Here's what I've done so far:
I have allowed all UDP traffic in both UDP_IN and UDP_OUT sections of my CSF configuration.
I have opened...
Hi Guys
I've been trying for a month to stop LFD warnings from legitimate PHP scripts that are run from cron, but none of the suggestions I've found are working.
I've tried ...
In /etc/csf/csf.signore
/path/to/script.php
In /etc/csf/csf.pignore
cmd:php /path/to/script.php
exe:/path/to/script.php
exe:/opt/cpanel/ea-php72/root/usr/bin/php-cgi /path/to/script.php
exe:/bin/bash -c /usr/bin/php...
I have installed CSF firewall on Centos Stream 9 on my VPS server successfully without errors.
However, after I set some IP ranges in this file:

Hello, I am a new CSF user. I am using Almalinux 8.9 and cpanel. I have successfully installed CSF. But I couldn't achieve my main goal.
I want to block all requests coming directly to my server's ip address. But I want to allow 3-4 ip addresses.
I allowed my own ip addresses in the CSF interface. And I entered 0.0.0.0.0/0 in the Deny field to block all other traffic. but this time the traffic...

Hello!
Recently i've been facing a problem in multiple server, when you add an ip to csf.allow on the UI it'll be added to the chain normally until you restart csf and lfd.
After the restart most of the ips on csf.allow won't be on the allow chain, if I remove them and add again it'll be added until the next restart;
The search option identify the ip on csf.allow but won't find it on the allow...
Hi,
I have setup CSF on our server but we're facing some troubles with too many IPs being blacklisted.
Many IPs that our clients access their e-mail from (dynamic ip ranges) are getting listed in Spamhaus, and thus CSF is blocking their connection to the server. I've checked csf.blocklists file but every RBL entry there is commented, so it shouldn't be affecting this, right? Anyway, i tried...
We currently have a custom blocklist and we managed to implement a webui for asking an unblock. But as the blocklist can only be reloaded each 3600s, the user have to wait a maximum time of 3600s to get unblocked.
Is there a way to trigger a blocklist reload within CSF/LFD from SSH? In this way we'll be able to unblock instantly an user.
I use CC_ALLOW option to add a couple of countries I want to whitelist but the problem is I'm still getting those countries IPs blocked (in temporary block list).
After upgrading to Rocky Linux and latest cPanel install, they wont allow Host Access Control anymore. So, I am trying to block all SSH connection except allow IP in the hosts.allow:
=============================
ALL : 1.1.1.1 : allow
sshd : 1.2.3.4 : allow
sshd : ALL : deny
=============================
What rule in the CSF can be defined to achieve the above SSH to block all incoming...
I am a victim of (D)DoS attacks for at least 2 years now from a very persistent attacker. The attacks are coming from spoofed IPs and the attacks are so low that it isn't distinguishable from normal traffic according to my provider (Hetzner).
CSF is able to detect them and block it according to the logs from what I can see in the /var/log/syslog file as the attacking IPs are there. Yet CSF is not...
