Hi,

I'm trying to figure out what configuration setting within ConfigServer Security & Firewall is causing SMTP emailing with 3rd party providers (in our case Mailgun) from working... If I disable ConfigServer Security & Firewall then the email sending works fine.

WordPress SMTP Mail Log

Versions:
WordPress: 6.4.3
WordPress MS: No
PHP: 7.4.33
WP Mail SMTP: 3.11.1

Hello,

I see one IP address blocked on CSF:
# csf -g xxx.xxx.xxx.xxx
(...)
IPSET: Set:bl_CXS_LF_HTACCESS Match:xxx.xxx.xxx.xxx Setting:CXS_LF_HTACCESS file:/etc/csf/csf.blocklists
(....)

As I see on LFD log, the IP was blocked by LFD for htpasswd fail.

However, I'm unable to unblock it from SSH by csf -tr or csf -dr command. Which command I should use to unblock this IP address?

Thanks.

We have this error on direct admin csf install:

Hi,
either I don't know how to use it or csf.pignore is not working as it should, this is what I tried so far:

# stop monitoring wordpress breakdance /tmp files

dir:/tmp/systemd-private-*/*

sudo sh install.sh

i repeat i did not change anything, i did not enable csf, testing...

I had an application level attack on a Wordpress site that brought the server to its knees. First time I've had this happen ever running about a half dozen small business websites. Configserver is loading multiple RBLs like FIREHOL, etc. I did a blacklist search and out of like 60 lists the IP only showed up on the Barracuda RBL. However the link to the actual RBL gives a 403 error.

Does anyone use the connection limit protection or port flooding settings that doesn't have network level DDOS protection?

What would be typical reasonable settings for a server that is just running website applications that has maybe max 40 website users at any time plus bot scraping traffic and virtually no FTP and maybe one SSH session open at a time? Nothing else such as external MySQL...

I have that error if I put RU as blocked:

CC_DENY = RU,CN,UA,VN,BY,HK,IL,KZ,KP,SA,KR,SY,TH,TW,JP,ID,BR,AR,BD,CO,MA,SG,KR,ZW,AZ,PL,PY,SD,CI,EG,MZ,MX,PK,NP,TZ,MY,PE

Error: FASTSTART: (CC_DENY IPv4) [] . Try restarting csf with FASTSTART disabled, at line 5790 in /usr/sbin/csf

If I remove RU from CC_DENY list and restart csf everything is fine and work well

hello, I am experiencing a csf and cmm download error with wget and wget respectively.

Connecting to download.configserver.com (download.configserver.com)|94.130.90.175|:443... failed: Connection timed out.

my server does download other files via wget so i guess there is no problem with that, however i have a doubt if your firewall may be somehow blocking my server ip.
thanks.

Does this error indicate a Zone file error? If so, what is the best way to correct it?

Hi,
I'm getting a lot of lfd on server: Suspicious File Alert , generated by Breakdance page builder for Wordpress.
Looks like this:
File: /tmp/systemd-private-3d4985084fd3401ca76423f2a737ddb8-ea-php81-php-fpm.service-PysP3o/tmp/breakdance-746d3b64/twig-auto-generated-cache/69/6935f4b89776a7d6e242d5319b554acd.php
The file is always different.

How can I exclude /tmp/ folder or disable...

Hello,
i have a service to run only to 127.0.0.1 (for example 127.0.0.1:25000)
and i want to reach from public ip.

i can't expose service on public ip directly.
so my goal is redirect port 25000 to 127.0.0.1:25000 and apply ruleset from csf.

i try to
nano /etc/csf/csf.redirect
w.x.y.z|25000|127.0.0.1|25000|tcp

but
Error: csf: Incorrect csf.redirect setting ( ): , at line 3226

how i can do...

Hi!

My server uses for instance 1.1.1.1 and I want to redirect port 60000 (1.1.1.1:60000) to another server's 2.2.2.2:3392 TCP port.
For this I put the following in csf.redirect:
1.1.1.1|60000|2.2.2.2|3392|tcp

My problem is that this opens TCP port 60000 from anywhere. It doesn't matter what is in csf.conf TCP-IN section (60000 isn't in it, but if a put !60000 it locks it for everyone,...

Since our servers upgraded to Alma Linux 8.9, each time the servers reboot, CSF does not operate as normal until after its restarted via WHM.

On one server that uses PHPMailer and Office 365 SMTP, any emails that are sent by the cPanel account will fail due to network is unreachable and in the /var/log/messages it shows outgoing connection attempts to port 587 being blocked. This is happening...
