![]() ![]() proceed to sanitize and insert data and run reports $result = mysqli_query($con, "SELECT * FROM reports WHERE (ip LIKE '$ip' AND time >= '$fresh')") exclude your own servers from reports due to dumb user errors CSF will call that script whenever an IP is blocked, and you have the script assign the variables you need using the arguments in the output. The way it basically works is that you build a script to be called on an event using CSF’s BLOCK_REPORT functionality. ![]() CSF itself does the rest and provides the great bulk of the malicious IP data. I wrote the honeypots, the web form failure scripts, the database scripts, and the scripts that interface with CSF. Not being one to reinvent the wheel, I let CSF do between 85 and 95 percent of the work. Of course, you can do all of this with firewalld and fail2ban if you want, but it would involve a heck of a lot more work. ![]() It just kind of morphed into a blocklist from there. That’s actually how this project began: I wanted an easy way for all my servers to share their events with each other. There would be more entries, but because the servers share their observations (as well as actions against the honeypots and web forms) with each other, IPs that act maliciously toward any one server or site are blocked by the rest, as well. This is my page on AbuseIPDB, by the way. That avoids permanently banning an IP due to a temporary situation like a hack, breach, or malware infection, once it has been resolved.Įvery IP that winds up on the list is also reported to AbuseIPDB in real time so if you already use AbuseIPDB, you’re already benefiting from CSF’s work on my servers. In a nutshell, if an IP is not observed misbehaving in that time period, it is rehabilitated. IP addresses that have behaved themselves are automatically removed between 72 and 96 hours following their most recent bad behavior, as reported (or not reported) by both CSF running on the servers or scripts running on the sites and honeypots. The philosophy behind those lists rests on rehabilitation by ephemerality. #Ip2location variables wordpress function updateThey contain only the worst offenders’ IP addresses and are only updated once a day (I may change that soon to make them update more often), but they’re free. #Ip2location variables wordpress function downloadMultiple servers, numerous honeypots, and numerous failure scripts on public contact form spam filters also contribute to that database, which in turn is re-imported into CSF (and other firewalls that can import text-based blocklists) so all of the servers benefit from the data.Īnyone in the interwebs-connected world can download free, public versions of the blocklists if they like. In my own case, one of the things it does (via an external script) is populate a remote, ephemeral database of malicious IP addresses that generates text files that can be downloaded by other servers and firewalls. It can block IP addresses or ranges automatically, manually, or programmatically from the GUI, a terminal, or a script temporarily, permanently, or temporarily-to-permanently and it can trigger other, root-defined processes upon doing so, or upon rehabilitating the IPs. You can make it forgiving, heartless, both depending on recidivism, or anywhere in between. The default configuration is sensible, but it can be customized as necessary for a particular use case. It very handily does all the work that firewalld and fail2ban combined do, and then some. This thread reminds me of why I still use CSF. ![]()
