I find CSF very difficult to understand, perhaps because it is so low-level in its configuration. I am getting an email message for every malicious intrusion to my web server, and each message is sent to an invalid address, in spite of editing file

Code: Select all

/etc/csf/csf.pignore

! I've searched the Web, and all I can find is advice to edit internal csf files, instead of using the WHM csf interface to fix this. So frustrating!

Here is a typical email. Let me know if you need the headers, too.

I think the answer is to select WHM > Plugins > ConfigServer Security & Firewall > Firewall Configuration, and make the following changes:
1. LF_ALERT_TO=EmailAddressForNotices
2. LF_EMAIL_ALERT=NO (no alert on IP blocks)
3. LF_CPANEL_ALERT=NO (no alert on normal cPanel usage)

You must then go to bottom of page, click Change.
On next page, click Restart csf+lfd.

That's all a guess based on experiments. Can anyone confirm?

Nope. I'm still getting these unnecessary notices, and sent to an invalid address. Is there a way to submit a bug ticket? Frustrated!
