Would it be possible to somehow put GeoIP in regex.custom.pm?
Something to filter IP by countries and work differently by countries?

Thank you.

One class of malicious user/uncooperative person is the prober. This is the source of most traffic on my websites, and consists of trying to find weaknesses to exploit.

Typical accesss are to files and directories with names like these:

wp-login.php, wordpress, wp-includes, PMA2017, admin, mysql, db, database, phpmyadmin, program, myadmin...

Why can't csf add an option to look for sequences...

I'm not sure exactly how to call it.
I have the same problem on multiple server, we are giving email services to a company which has 10+ person working in an office . The office connects to the internet via a NATing router, so everybody is seen coming from a single IP.
Now if a single person fails his password a couple time from , that IP will be banned, and everybody will loose access .
So...

The following is a list of features that I think are necessary to improve CSF and LFD integration; most of them are related to CSF blocking IPs:

- CSF should add the same information on manual blocks (csf -d) to the csf.deny files as LFD does (date, geolocation and hostname)

I'm requesting this, since when spammers strike our servers from many IPs a little bit at a time (instead of just a...

Hello,

Currently we are using CSF on our servers and we are testing with the recaptcha ability to unblock the IP address.

Now our customers are possible to unblock their IP it could be handy if they know why they are being blocked.
Is there any way to make this work?

Example, I am blocked and try to visit the server it shows me the message that I am blocked.
There is an option to unblock by...

Right now, the page is served out with status 200, which means that if for example a search engine crawler gets blocked, it will update its index with the blocked page content. I've added the following to the top of index.php in ~csf/public_html/index.php for now: but an .htaccess rule could also be set up to do the same thing.

We have using this useful tools, we found totally helpfull,

we suggest to add a option to maintain a ip blocked even if we flush the all the blocks, like adding a new file called (ex : csf.unignore) any ip in this file will not deleted from the ip_tables and will be permanently in the block unless we remove it from the file,

i hope the suggestion has a meaning for you.

Hello,

A few weeks ago I upgraded my system from Debian Jessie 8 to Debian Stretch 9 but till yesterday I didn't notice this issue. I tried to connect to an external ftp and I connect but it is not possible to list the directory contents, strange because before the upgrade with the same CSF conf I was able to connect to this ftp. I double check CSF conf and the port 21 is in TCP_OUT, SPI...

I want to redirect the blocked page to the new address

Example :

When the user was blocked Go site2.com

First, thanks for all of your incredible software, especially CSF and Mailscanner, which are amazing! Regarding CSF, I have a usability suggestion - have you ever considered moving the Quick buttons to the top of the page in their own section? Quick Allow, Quick Deny, Quick Ignore, and Quick Unblock. It's just not very quick the way it is right now having to scroll down the page to get to them. I...

Starting yesterday, all of our cPanel servers are getting hit with a massive amount of SMTP Authentication failures, from distributed IP addresses. Yesterday alone, we are seeing over 8000 different unique IPs involved in these distributed attacks.

The flood of LFD emails caused us some email issues. I tried to disable SMTP AUTH failure emails, or at least route them to a different email...

Hello there,

Nearly all of my servers that run Exim are constantly being attacked by remote nodes trying to brute through an AUTH command before advertised. Every day I get a big list of AUTH command used when not advertised in logwatch.

On a daily basis I'm blacklisting these remote nodes, because I know for certain they are scanning for open relays. Quite a big giveaway is also the HELO being...

can CSF be updated to use the new Cpanel mod-evasive Apache module

CSF is absolutely fantastic, we use it on many of our servers, but on our cPanel servers in a cpanel DNS cluster we are constantly bombarded by emails about WHM/Cpanel root access alert due to each of the 5 servers in the cluster remotely pulling various DNS data as part of cPanel's built in DNS cluster management. Every time a domain is edited by a customer or by management, every server reports...

I find the style of csf's Off/On setting buttons confusing at times. I am not sure if a button is Off or is On. I am used to the Off/On button styling used on the iPhone which uses a round white slider with button background of green=on and white=off (with optional 1/0 indicators in the background)..

Perhaps make csf's buttons status clearer by styling the current state with bold red text and...

it's possible to do this from a simple bash command but it might be useful to less skilled users to have an option where LFD can also add an ip ban to cloudflare when the user provides an api key

might be too much to maintain for permanent rules, maybe make it part of the tempban feature?

when the feature is enabled, csf -td or csf -tr could also do the api call to cloudflare

note that...

EXPECTED:
PT_SSHDHUNG is supposed to kill sshd: unknown and sshd: unknown processes.

PROBLEM:
It doesn t kill sshd: unknown

SOLUTION:
Change the following line in lfd and add a test with SPACE at the end just like this sshd: unknown <-- note the space at the end.

from
if ($cmdline eq sshd: unknown or $cmdline eq sshd: unknown ) {
to
if ($cmdline eq sshd: unknown or $cmdline eq sshd:...

While mailscanner does not provide protection for outgoing spam I guess it could send some alerts when the EXIM queue size reaches a size that could suggest spam is being sent

Your netblock function counts number of block episodes within a class.
I would like one that counts by number of unique IP addresses within a class.

So this didn't work as *I* had intended- by your mentioning ddos mitigation it is clear that you meant this to be use against rapid fire bombardment. I, on the other hand, thought it would be useful to block repeat offender bullet-proof type hosting...

It would be great to have a mysqladmin processlist attached on the warning emails (if it's detected to be installed), since I see on the PS that mysqld was active but I don't know what it was doing. Perhaps a different command from DB Governor can be used instead if it was installed on the server.

Also an iostat -xdk command would be helpful on cases that there's a high IO wait state.
