We have recently been having an issue with JetBackup restoration processes getting kill by CSF. If we disable CSF the restoration process goes off without a hitch. Troubleshooting with CPanel and Jetbackup we narrowed this down to CSF killing the mongod process for JetBackup.

So per JetBackup support we placed exe:/usr/local/jetapps/usr/bin/mongod in the pignore file. This worked for a while but...

Hello,

I'm experiencing an issue where the custom firewall script csfpost.sh is no longer executed automatically, likely after the recent cPanel or CSF update on March 19, 2025.

Environment:

cPanel servers running CloudLinux 8 & 9
Imunify360 installed
ConfigServer Firewall (CSF) / LFD enabled
The script (/etc/csf/csfpost.sh) contains custom iptables rules, for example, to allow outgoing...

I have an AlmaLinux 8 server running CSF + LFD, using ipset for a larger corpus. Load looked very, very high, and I noted in the web server logs that IPs which were blocked in CSF were hammering some of my domains. So I did a systemctl status on iptables. It responded that iptables was dead . systemctl status csf showed that CSF was running.

I did a systemctl iptables start , and load plummeted...

The Hourly Log Scanner Report is not delivered and is blocked because MailScanner flagged this report with virus:

Clamd: msg-691013-207.txt was infected: YARA.r57shell_php_php.UNOFFICIAL
Clamd: message was infected: YARA.r57shell_php_php.UNOFFICIAL

Where I can do a check of this file msg-691013-207.txt ?

Thanks,
Sergio

At I see 2 buttons View lfd statistics and view system statistics.

These are not displayed on my CSF. (Installed on Debian12)
Is there something to be done at csf.conf ?

Hi,

I recently added Abuse IP DB to my CSF blocklists file as I've seen an increase in web scanning, and all of the source IPs were listed on AbuseIPDB, so I figured it may be a good source to add to CSF blocklists..

I noticed some unwanted traffic this morning, and the IP was on AbuseIPDB, so I started digging and found that the csf.block.abuseipdb file in /var/lib/csf only contains around...

Are there any plans to release a version of MSFE that supports the webuzo panel?

Hi all,

Used the CC_DENY option to block AS16276 since some bots hosted there are hammering my site.

Noticed email to some users can no longer be delivered, seems that their mail server is hosted on AS16276 (mail.ovh.net).

Is there any solution to fix both problems? Continue to block AS16276 but allow mail to be delivered?

So we're running a Proxmox server with several LXC containers, Proxmox is Debian, and Containers are Centos 7. We install CSF on both the Host and the Containers.

We configured everything properly and running 'perl /usr/local/csf/bin/csftest.pl' under the container gives OK on all tests:

# perl /usr/local/csf/bin/csftest.pl
Testing ip_tables/iptable_filter...OK

Hi,

CSF or LFD do not detect failed logins via email and do not send report emails.
Hi, I've been using csf for a while now and I've noticed from the journal logs that there are several failed login attempts via pop and imap. It seems that these, unlike ssh login attempts, are simply ignored.
cat /etc/csf/csf.conf | grep mail.log
POP3D_LOG = “/var/log/mail.log”
IMAPD_LOG = ”/var/log/mail.log”

we have written rule in csf allow to only allow connection to port 25 from server ip but we are being able to telnet to this port from another ip

rule is written in csf.allow

tcp|in|d=25|s=server ip

our intention is only the server should be able to send and receive mails that is we created mail and from cpanel we login into mail and from there only we should be able to...

I have a web site that I do not want to be accessed from outside of our local network.

It resides on it's own IP address, so I used the Deny Server Ips feature to block all traffic on it's public IP.

But I can still access it from anywhere.

I notice that the purpose of this feature is to allow blocking of all traffic on server configured IP’s if they’re not in use .

Does that mean that if an...

One of client informed me that, he is unable to access their site hosted in my server. I then accessed their PC using anydesk, their IP was in firewall whitelist still they were unable to access. I then stopped the firewall using command line and it started working, then started the firewall and it stopped working again. I then stopped CSF and started the firewall from WHM menu and then it was...

Since the Comodo ruleset is dead, I'm trying to switch over to OWASP.
Mod_Security & the OWASP ruleset are installed on a CWP server.

But when I do, LFD doesn't send the email alert or add it to the csf.deny

CSF setting are:

LF_MODSEC = 5
LF_MODSEC_PERM = 1

I have tried different paths of MODSEC, the default is:
MODSEC_LOG = /usr/local/apache/logs/error_log
and
MODSEC_LOG =...

For whatever reason, When I RU is in CC_DENY, any IP in cidr 169.244.0.0/16 is getting blocked. I downloaded Maxmind's GeoLite2-Country-Blocks-IPv4 DB just to make sure it wasn't a mistake on their end and their DB classifies my 169 range as a US based cidr. I'm unsure what to do at this point, other than either manually adding all the RU cidrs to csf.deny which would most likely greatly affect...

I'm trying to switch over from the Comodo ruleset (Since they are dead now) to OWASP.
CSF/LFD is being used with CWP (Control Web Panel).

Need some help.

I use to get LFD notifications and automatic blocks when using Comodo, but now I get neither.

/etc/csf/csf.conf shows:

LF_MODSEC = 5
LF_MODSEC_PERM = 1

I changed from cPanel to CWP Control Panel and I am running the latest version of CSF and everything was fine until the otherday I could not access any domain on my server, yet I can access any IP on the server so when I need to access a domain I have to disable CSF.

I have my IP in csf.allow & csf.ignore and it is still blocking me on Port 80 and I cannot figure out why, anyone have...

None of the mail coming from my customers contact forms are being scanned. When I look at the email in Mailscanner FE it says Not Scanned at the top. Consequently my customers are getting a ton of spam delivered to their inboxes generated from their contact forms. I have searched endlessly but nothing is white listed that I can see that would cause this. The server's IP is whitelisted in CSF, but...
