My server has 4 IP addresses, one of which has come under the Great Firewall of China DDoS attack.

For the affected IP address (let's say it's 1.2.3.4), I want to block all port 80 traffic, so I created the following entry in csf.deny:

tcp|in|d=80|d=1.2.3.4

This works but not how I want. For example, I am able to successfully connect to port 80 (telnet 1.2.3.4 80). Then, only after I issue GET...

Hi,

When csf tried to upgrade earlier this morning I get an email that says:

Oops: Unable to download: 599 - Could not connect to 'www.configserver.com:80': IO::Socket::INET: connect: Connection timed out

In WHM now there is only this text and no button to click to upgrade.

Hey guys,
I'm new to CSF, but I think it's amazing! I am running CSF v7.60 on CentOS 6.5 Final.
I am trying it on an asterisk PBX that is dedicated for VoIP faxing and am having some issues which I have been unable to diagnose. When the CSF is enabled, faxes fail. When I disable CSF and load a regular iptables script instead, they are flawless. I haven't been able to figure out why.

I've played...

I'm running into an issue with IP's getting blocked for Port Flooding. Most specifically, Whenever I have an Iphone try and configure an email account, they will be blocked for port scanning.

Do I have something set wrong?

Any ideas on optimizing these settings to stop this behavior.

Thanks,
Cliff

Hi,

In csf ver 7.59 on CentOS 6.6 with WHM 11.46.2 (build 4), when we try to compare profile configurations by selecting protection_high as first config and /etc/csf/csf.conf (current config) as second config, it doesn't show anything! However, if we select protection_medium or protection_low, it then shows the table of comparision. Is this a bug or are we doing something wrong?!!

Thank you

I just happened to notice that I am able to add the same IP as many times as I want via the Quick Deny. Checking another server, I'm not, as expected.
csf: v7.58

Is this a bug or did I break something?

Thanks!

Where do I find the option to change for this?

Folks, I have csf/lfd installed (no cpanel) and I'm having a hard time getting my game server to work.

It uses ports 10777,11777,9000,9010,7777,7778,7787,28902`

After trying to get all the ports in the right spots, just to get it going I added all of them to the TCP_OUT,UDP_IN and UDP_OUT sections of the csf.conf and it didn't work.

The closest I got was when I added the shell script that...

Hello,

How do I block access to port 25 for all IP addresses and allop only my hosted mail filter access to port 25 for mail delivery?

I tried to add this to the deny rules:

tcp|in|d=25|s=all

then added the the mail filters IP range to the allow rules. I tried to test using mxtoolbox but they are able to connect and get a 220 and 250 session transcript. I was under the impression that this...

Hello,

What happened to these localhostrelay settings? they were very helpful. I checked the changelog and there is no mention of their removal.

Good day and let me first apologize if I am posting in the wrong area.

I receive 70-80 alerts from lfd..is there a way to shorten the list?

First of all, I'd like to say I am most impressed with the work done on CSF, it's leaps and bounds ahead of manually editing iptables at the command prompt. Especially for someone who isn't very strong in linux. With that said..

We have a new server build of Ubuntu 10 LTS, which originally came with a DirectAdmin control panel. DA had huge issues in getting along with Webmin, so the ISP rebuilt...

As the title says, we have CSF running and successfully blocking IPs from .htaccess based login failures. We are running nginx, but we have updated the log file locations to our nginx logs and CSF is working great. IPs are auto added to csf.deny after several failed login attempts.

Our problem arises in that users can still load up the website even after their IP has been blocked. They are...

I keep noticing that the iptables service isnt running - it seems like since I installed CSF - just from a timeline perspective. Is there something I might have done wrong to cause this?

Thanks

Csf function connection limit per ip is not working and conflict with nginx. Kindly help me...

Hi,

is there a way to ban users who are trying to bruteforce drupal / wordpress or other cms installations. For fail2ban you have options but does csf has options to counter this?
