New csf install on CENTOS 6.3 x86_64 virtuozzo with cPanel 11.34.1 build 7. The build automatically created a symlink in /sbin/ for iptables pointing to /sbin/iptables-multi, so I added another symlink for /sbin/ip6tables linking to /sbin/iptables-multi. Resolving fine.
csf starts when IPv6 disabled. VPS supports IPv6 and I have v6 addresses that I like to use for a couple of domains

Hello,

I am running LFD/CSF on three servers and on all servers I have the same problem since the first day when I set-up the server and installed LFD/CSF.

I am running nginx + php5-fpm + MySQL and lfd.log file is full of warnings:

Hi,
Currently have CSF v 5.72
The firewall does not seem to be blocking IPs. I am receiving hundreds of emails saying that an IP (108.166.114.12) has been permanently blocked however there are repeated entries/emails for the same IP

When I try and search for the IP in the IP Tables the following is displayed, which is not a normal result from what i remember

Searching for 108.166.114.12......

We have a new server installation of openSUSE 12.2 (x86_64) and installed csf 5.73. The process ignore reporting does not seem to be working correctly. We have included lines to ignore apache including all three of the following:

user:wwwrun
cmd:/usr/sbin/httpd2-prefork -f /etc/apache2/httpd.conf -D SYSTEMD -k start

We still get emails with:...

Hello,

CSF is latest version, Geo database unzipped and stay in correct folder but it seems that CSF do not try use it. PurePerl require few perl modules (like Import, Export etc.) all of them installed by CPAN but CSF still not use database. Some testing option might be useful for such case.

Hi all. I've been working in mitigating the attacks I'm suffering in my server and now I have a question.
Is it possible to block IP ranges (IP blocks) when lets say 4 or more IPs from that block are already banned?
Here is a small capture of the traffic on port 80 during the last attack:

Hi,

I can not update anything having to do with access to the Redhat network with CSF running. I have two switch off CSF just to update PHP, etc.

Hello,

I have a dedicated cpanel server at a colo here in Virginia. We have 1 client who has employees who connect to virtual desktops on a Citrix VM. While working on their virtual desktops they cannot see any websites we host; traceroutes show them traffic stopping one hop before our server.

We switched to CSF from APF a few months ago. I have this clients Citrix ip range (an entire /24)...

Hi there -

My servers are setup to only allow ssh by root. These alerts work fine with actual root logins but I've also gotten a couple of alerts with no evidence of an actual ssh/root login -

lfd on server.servername.com​: SSH login alert for user root from 62.212.154​.143 (NL/Nether​lands/www.​digiinfo.n​l)

When I parse /var/log/secure for this IP, there are no log entries. When I parse...

Hi,

I have a customer who's IPs are continually being blocked (he appears to have extremely frequently changing dynamic IPs!)

Is there a way I can find out more about what is causing the block? When I go to csf.deny is just says too many temp blocks :(

Thanks!

Hello,

I'm trying to configure LFD to send me an e-mail only when root logs in via SSH. I have LF_SSH_EMAIL_ALERT=1 and I get e-mails on every login to SSH, which I don't really need, especially since FTP is disabled and I require all users to use SFTP so I don't need an e-mail everytime they FTP in to upload files. So I just want alerts on root login, is there any way for me to configure this?...

Hello, good afternoon all ;)

Thanks for support and assistance.

Hi,

Looking at the following line, how do I know which email account caused the firewall block:

vps lfd : (smtpauth) Failed SMTP AUTH login from 196.214.185.114 (ZA/South Africa/dc1.mesure.co.za): 5 in the last 300 secs - *Blocked in csf*

Got a weird problem. Running Centos 6.3, cpanel, csf. The server isn't receiving email. It sends fine.

csf configuration shows port 25 inbound/outbound open.

From two other servers I tried to telnet in to the server and the connection is refused ( telnet xx.xx.xx.xx 25 )

It is refused whether csf is enabled or disabled. Both the server IPs are also whitelisted in the firewall.

Hi

I'm new to this ConfigServer/ModSecurity.

I've got an issue with CSF blocking PDF uploads bigger than 4mb. I've included the logs and removed anything that might identify our site/login details :)

Can anyone advise what to do here?

Thanks
