Hi!
Suddenly today I get this error in the log and it is all 4 blocklists that it cant find. It have worked for 2 month without a problem. What can be wrong

This is the lines in blocklist

csf01|86400|0|
csf02|86400|0|
csf03|86400|0|
csf04|86400|0|

Hello,

Could someone tell me how to make all together the:
CSF smtp auth +
localhosts +
tls cipher
- part of the rules in the
auth_advertise_hosts= section
of exim.conf?

auth_advertise_hosts =
localhost : ${if eq{$tls_in_cipher}{}{}{*}}
${if match_ip{$sender_host_address}{iplsearch;/etc/exim.smtpauth}{*}{}}

So these two lines should work together in the auth_advertise_hosts rule of...

As indicated:

Is there any guidance or roadmap from CSF on --gulp-- firewalld, or other, as RHEL seems to indicate these may be dropped in the next version.

Thank you.

I am running a WHM CloudLinux8 based dedicated server that has both ModSecurity and CSF/LFD (v14.22) installed.

Despite being set-up correctly as far as I can see, CSF is neither temporarily nor permanently blocking any repeat offender IPs recorded by ModSec in the server's main error_log

I can see lots of IP entries and rules matches in WHM > ModSecurity > Tools so I know ModSec is working....

Something has happened overnight and blocklists cant be downloaded.

One of client informed me that, he is unable to access their site hosted in my server. I then accessed their PC using anydesk, their IP was in firewall whitelist still they were unable to access. I then stopped the firewall using command line and it started working, then started the firewall and it stopped working again. I then stopped CSF and started the firewall from WHM menu and then it was...

Since the Comodo ruleset is dead, I'm trying to switch over to OWASP.
Mod_Security & the OWASP ruleset are installed on a CWP server.

But when I do, LFD doesn't send the email alert or add it to the csf.deny

CSF setting are:

LF_MODSEC = 5
LF_MODSEC_PERM = 1

I have tried different paths of MODSEC, the default is:
MODSEC_LOG = /usr/local/apache/logs/error_log
and
MODSEC_LOG =...

I see that csf blocked ips are logged in /var/log/messages.
Is there a way to have it log the name of the blocklist that triggered the block?
I am using /etc/csf/csf.blocklists to specify blocklists.
something like iptables LOG --log-prefix some name: ?

thanks.

Hi!
Newbi on CSF
Perhaps obvious answer but I dont find

If I allow 1 country in the allow list and the deny list is empty, does it mean that all countries exept the one allowed is denied

I'm trying to switch over from the Comodo ruleset (Since they are dead now) to OWASP.
CSF/LFD is being used with CWP (Control Web Panel).

Need some help.

I use to get LFD notifications and automatic blocks when using Comodo, but now I get neither.

/etc/csf/csf.conf shows:

LF_MODSEC = 5
LF_MODSEC_PERM = 1

MODSEC_LOG = /usr/local/apache/logs/error_log

I tried changing it to...

I changed from cPanel to CWP Control Panel and I am running the latest version of CSF and everything was fine until the otherday I could not access any domain on my server, yet I can access any IP on the server so when I need to access a domain I have to disable CSF.

I have my IP in csf.allow & csf.ignore and it is still blocking me on Port 80 and I cannot figure out why, anyone have...

I have noticed a lot of cloudflare IP's accessing my site. I added them to my csf.deny file but see they are still accessing my site.

Using cPanel and WHM.

Any ideas why they can still access the site? Been using csf successfully prior to this.

Hi guys, I'm new here, but I've been using CSF for many years! Over 2024, there has been a surge in Internet attacks and I've recently discovered something with my CSF install that I think is weird and wanted your opinion and eventually maybe a suggestion to mitigate the issue:

In my config, I have:
LF_TRIGGER = 0
LF_APACHE_404 = 200
LF_APACHE_404_PERM = 3600 (1 hour)
LF_INTERVAL = 300 (5...

Hi,

I think CSF doesn't attention to allow list of IPs when we temporary deny an IP address
But it fails deny when we want to deny normally

Thanks

Hi, i already set email notification to off but seem like i still received notification like almost 1k per day.

May i know how to completely disable all the notification please?

I have a VPS with Almalinux8, Cpanel and CSF installed and with a 600Mpbs port. I started experiencing speed issues with FTP uploads (because it limited data upload) and so to check the speeds from the server, I installed speedtest cli.

The results with CSF/LFD activated are:
