Emails are the same except the code is different each time.

Whenever csf updates it produces an output like:

‘csf.blocklists’ -> ‘/etc/csf/csf.blocklists.new’

this is totally confusing. If it's new that would imply it is replacing the old file. Yet, how can it be new AND functional if it's labelled something like csf.blocklists.new

Are we to assume the old (not new ) is still in use?

Or, is .new the new new ?

Totally confusing and without any...

Hi, I would like to run my own script when an LFD alert is generated.

Is this possible?

Thank you!

So we have had an issue with some updates coming down for WHM - and in the process we discovered that the server was blocking a specific range of IP adresses.

If you search for the IP via the WHM gui you get this return

Table Chain num pkts bytes target prot opt in out source destination

filter CC_DENY 93147 1686 80924 DROP all -- * * 162.55.0.0/16 0.0.0.0/0

But if we try to unblock that...

Hello,

When viewing the CSF firewall in cpanel WHM there is a CSS style error noticeable at the top of the Juniper theme page for the Search field.

Console shows error:
Source map error: Error: request failed with status 404
Resource URL:
Source Map URL: bootstrap.min.css.map

If I fix this on my end will updates overwrite my fix?

I was wondering if there are any pre-existing hooks/script support for the moment CSF downloads and pulls the geolocation database download? Or would it work to just monitor /var/lib/csf/Geo for file changes?

Hi,

I would like to configure CSF to not block IP-s form some countries in csf.deny ( permanent block ) but still implement the firewall rules for closed ports and other configuration. Temporally block should also work normally.

I know of CC_Allow option but when i add county in that list it ignore ALL firewall rules and i`m looking for solution just not adding the IPs in csf.deny .

Any...

does anyone here have any tips to setting up nginx reverse proxy to properly and fully serve up all of csf's webmin control panel correctly? right now, it mostly works with examples available online for putting webmin behind nginx, but, when editing csf properties and attempting to save them, the proxy redirects fail. i'm left with having to make the csf config edits via command line and manually...

Hello,

I have had some issues with a security research company binaryedge.io. From time to time they scan some of the web site on our servers without throttling activity or connections and my server loads spike, sometime well over 36 load for a an 8 core server.

I spoke to Linode abuse, since mane of the IP's were theirs. Linode say they are a 'Security Research' Company, so they are not...

We are seeing that imap-login is aborting IMAP connections during our nightly upcp cron job which is triggering LFD to add customer IPs to the deny list even though the password is correct and after unblocking they continue to check email fine. Likely a problem with cPanel directly, but since the problem presents itself in CSF first, I wanted to see if anyone else has been seeing this happen? We...

Hi ConfigServer friends!

I recently installed the CSF and LFD software onto my Cpanel server and I experiencing some problems with users who wish to connect via FTP.
My FTP keep complaining to me that they are unable to list directories of the folder that they have access to.

When I attempted to replicate their experience, I found that this complaint was true.
While using Filezilla ver 3.58.0,...

Hi there,

When csf is disabled the update works.

I think the documentation is not very explanatory when it comes to the BLOCK_REPORT feature.

I suspect more than one person found out that this only works for triggers from LFD after a lot of debugging.

This hampers more or less the idea of being able to report abusive IP's or report them because half of the features of CSF rely on, well, CSF and not on LFD.

Since CSF already has the option to...
