Hallo
I use Juggernaut Danami's overlay for CSF ,
I'm using it on Debian 10 and Plesk, everything seems to be working fine
except for one thing: Custom Login Failure Triggers but only for MSQL
others work very well

What I know and it works is:
Login error logs are saved at /var/log/mysql/error.log

Hello and I hope everyone is healthy and safe.

I manage a server which gets a lot of malicious hits from outside US. I use CC_DENY which works well. However, as mail is being sent out and oftentimes some foreign recipients do a dns check for dns on the server, it is also blocking that which degrades service.

What must I do to continue to use my CC_DENY list whilst also allowing foreign dns...

Hi! hope this message finds you well. For the last 2 weeks, we have been in a problematic situation, we have designed a custom website 2 months ago but from last 2 weeks, we have noticed unauthorized access to our website which is having a big impact on our general and real visitors. for example the slow loading to our page.

Good morning,

I wish to rate limit by outgoing trafic using some IPTables rules like this:
iptables -A OUTPUT -m hashlimit --hashlimit-upto 5000/sec --hashlimit-burst 10000 --hashlimit-mode dstip --hashlimit-name loutput_ip --hashlimit-dstmask 24 -j RETURN

If I just add these rules in IPTables, will it break CSF? Or is there a way to add some custom iptables rules inside CSF?

Hi :confused:

I noticed this content mentioned on readme
Local IP addresses cannot connect to the UI (i.e. all IP addresses configured on the server NICs)

That seems as asking feathers from tortoise but reasonable to me and my favorite firewall. you guys can give me a feather :cool:

Hi,

I customized blocklist and add some urls like this:

and:

But after restart the csf, it tries to download this list but final file size on /var/lib/csf/csf.block.NAME will be 0 byte for such url
although for others is ok

Appreciate for any help

Hi,

I am blocking China via CC deny plus some manual rules as well, but some connections are still getting through.

It appears blocking is active as a csf grep for the IP address shows it as blocked:

csf -g 111.202.101.113
No matches found for 111.202.101.113 in iptables
IPSET: Set:chain_DENY Match:111.202.101.113 Setting: File:/etc/csf/csf.deny

Hi Everyone,

I am getting a lot of spam from quite a large US hosting company, Eonix, it seems they are a spammers paradise from what I can see.

I can get a list of all their IP's

I would like to some how create my own custom RBL list with all their IP's on if that possible? I dont want to totally block the emails just assign them a high SA score.

What is the best way to do this in...

Hello,

in csf.pignore

exe:/opt/cpanel/ea-php71/root/usr/bin/lsphp

exe:/opt/cpanel/ea-php73/root/usr/bin/lsphp
exe:/opt/cpanel/ea-php74/root/usr/bin/lsphp

Thanks!

Hello,

I am having trouble with this. Please can someone help me with the custom Regex. I tried to whitelist user in pignore, but not working. Basically I dont want these suspicious file notices as they are false positive, so I need a regex or to know how to whitelist this user:...

I apply the ports I want to open and, when restarting CSF, it opens all ports:

Has anyone here created a PHP script in order to blacklist IP addresses in CSF to the Sucuri blacklist using their API as can be done with Cloudflare?

You must install ClamAV (Clamavconnector on cPanel) or ensure clamd is running to use this product correctly
If the clamd socket is not automatically detected, and to clear this message, you must set clamdsock=/path/to/socket in /etc/cxs/cxs.defaults to the live socket location

how to solve this.

Is it possible to redirect all blocked ips to a new address liked siteaddress.com/blocked to notify if a user is being blocked.

I get a lot of clients who get blocked due to incorrect email login attempts so would like to show the users they've been blocked instead of the sites showing a 500 error.

Ran into an odd issue today, CSF was reporting that it couldn't restart. This was the error in the startup logs:

Error: FASTSTART: (csf.allow IPv4) [] . Try restarting csf with FASTSTART disabled, at line 5587

I disabled FASTSTART and that did allow CSF to start, but I have no idea what that means. Any idea?

Good morning,

I have two IPs in my cPanel server, one for web purposes and a secondary IP for outgoing email. To avoid malicious things use the secondary IP, I wish to restrict this secondary IP to only SMTP ports. How can I achieve that with the CSF plugin in my cPanel?

Thanks in advance.
