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:

(there is no filter in the capture, only port...

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.

The following command at shell times out after several minutes with CSF running:

time yum list updates

The output eventually reads:

There was an error communicating with RHN.
RHN Satellite or RHN Classic support will be disabled.

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 ;)

If possible change time temp ban in csf firewall ?

I did not find anything about it.

Someone can help me and tell me if you can and if you ... how to do?

Thanks for support and assistance.

Hello all,

I am seeing many failed entry attempts in my mainlog for exim. Here is a snippet from that log file:

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

First to thank the CSF developers for giving us this wonderful product.

Am using Centos 6.3 and dovecot v2.0.9.
