Hi team

I am using CSF and mod Security. I have implemented an automated reporting facility to AbuseIPDB.

It all works well - except occasionally, it sends a report to AbuseIPDB but does not block in CSF

When that happens, this is what is reported in AbuseIPDB

(CT) IP 12.345.6.789 (CA/Canada/-) found to have 190 connections;

This is what shows in Hits List for Modsec (there are many...

Hello
The spamassassin / mailscanner and configserver mailscanner FE do need some serious processor power.
Has someone find a config / work about, to have the mailaccounts etc continued to be managed by the CPANEL server,
but have the mail send (via secure connection) to a separate server to have there the spamassasin / mailscanner and mailscanner FE work done
before being sending back to the...

Hello friends.

How can we block sites like hackertarget.com/reverse-ip-lookup and host and block all domains on one IP address?

Is there a way to block it through CSF/LiteSpeed?

I have no clue why this is happening, but some emails are basically empty in the mail manage interface.

After the headers, there is just a message not found in Quarantine message and no other content, attachments, or actions are available. This only happens on seemingly random messages. Trying to figure out what is going on here.

Its not every day I find something this perplexing, so I thought I would toss this out there to the hive mind and see if anyone can guess what might be going on here.

Server is a Centos 7, fully updated server, high end specs, bare metal, latest Release version of cPanel. Running Litespeed.

This is so weird.

So, this url:

For any of you in the forum would load perfectly normally across all...

I have an entry in MSFE Blacklist for a domain (*.domain.tld). But I am still getting email from that domain. Any ideas?

Hi there,

From what I can make out, the settings are correct to only receive notifications for successful logins via SSH.

# Send an email alert if anyone logs in successfully using SSH
LF_SSH_EMAIL_ALERT = 1

LF_PERMBLOCK_ALERT = 0

Though we're still receiving alerts when there are blocks caused by failed SSH logins.

For some reason its seems that cluster members do not always respond properly when denying an IP address.

When Mailscanner FE is installed on a Centos 7 server with WHM/cpanel do global email filters at a cpanel account level still work? (they don't seem to).

I have a situation where mail TO a domain on the server is whitelisted in Mailscanner, and there are global filters at an cpanel account level for that domain, however mail that matches those filters is still delivered.

I have problem with coding in file /etc/csf/csf.deny.

When I'm editing this file in Python I'm getting error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xce in position 2882: invalid continuation byte .

Hello Forum,
I want to block an IP Adresse in the range of 91.241.72.0 to 91.241.72.254. Due to spam and multiple IP Adresse in that range.
So i added 91.241.72.0/24 #do not delete to /etc/csf/csf.deny.
And yes i restarted the firewall.

Then i tried to ping 91.241.72.1 from my host... no ping.. Great I thought it works.
The next day I got spam from that IP range agian. WTF!

After some...

Hi, i have two servers that every hour the settings are reseting, and removes on special cofig on TCP_IN, TCP_OUT and SMTP_ALLOWUSER,
i tryed to fix this reinstalling, searching for a cronjob but i already not found what is happening, on the logs there is no not about the resetting

Unless I have an IP address/port entry in the csf.allow (tcp|in|d=5061|s=my_ip_address/32), incoming SIP signaling with TLS transport (not UDP) on port 5061 is blocked.
I suspect SPI is rejecting this traffic.
Is it possible to turn off SPI on specific ports?

port 5061 is being opened with port knocking. I can see incoming traffic on tcp 5061 port with tcpdump, so I guess port has been...

Any idea how to make CSF Firewall only logging to file not the console ?
Using CloudLinux 8.5 with cPanel, last time i check the server it was correctly logging into the log file, but now it's shows the log too in the console.

Recently I started get these error messages. They are for one customer only.
Can anyone tell me what a possible cause may be.

Hi

I recently installed ConfigServer Security & Firewall - csf v14.15 on my VPS and there is an apparently easy problem to solve. A single client has access to the webmail blocked by the Firewall. The internet provider that serves you very often changes the internet IP. There are customers that the provider is another and changes with 30 days or more the IP address, but this provider is messing...

Hi

CC_ALLOW_PORTS_TCP seems to not be working for port 587 in combination with the Dutch (NL) country filter.

The connecting IP's came from NL but were not able to connect.

Thanks

Dear all:

I've been using csf at least 5 years, great product.

I have setup a new server and installed it as usual. But as soon I enabled it, all the network goes crazy, the network latency pikes high, making almost unusable :confused: , I thought I was having issues with the ISP, but I then disabled csf and everything back to normal, enabled it, and the network slow down inmediately.
