Stopping Web Server Abuse with Fail2Ban

At 4am yesterday morning I was awake. Luckily so, as I checked my email and saw a warning that my VPS had been running at 199% CPU for two hours. I went into my office and checked the logs. Someone had been hammering this site with HEAD requests since just after midnight with nearly 30,000 requests across different URLs in four hours.

If they’d hit the same page repeatedly, cached responses would have handled it. But by requesting thousands of distinct URLs, each request generated a fresh cache file, forcing PHP and the database to do real work every time. My small server was coping, but the load average was high.

I blocked the offending IP in .htaccess immediately. That stopped requests from reaching PHP, but I wanted a proper defence, something that would catch this kind of abuse automatically next time.

I already had Fail2Ban installed. I’d just never configured it for web server attacks. Time to do that.

Fail2Ban works by watching log files for patterns, then banning IPs that match too often. I needed two files: a filter to match Apache access log lines, and a jail to define the thresholds.

First, the filter at /etc/fail2ban/filter.d/apache-ratelimit.conf:

This matches every request in the log.

The jail decides what volume of requests counts as abuse. It lives at /etc/fail2ban/jail.d/apache-ratelimit.conf:

The logic: if a single IP makes more than 500 requests in 30 seconds then ban it for 24 hours. Adjust maxretry and findtime to suit your traffic patterns. Legitimate crawlers and real users won’t come close to these numbers, but an attacker blasting thousands
of requests will trip the threshold fast. These are not the numbers I’m using.

The ignoreip directive keeps trusted networks (monitoring services, your own IPs) from getting caught.

The changes to Fail2Ban are activated with the following command (as root):

And I verified it was running by checking the status:

Within a couple of minutes, the offending IP appeared in the banned list. I checked the access log, and there was nothing more from that IP. The requests weren’t just being rejected by Apache; iptables was dropping the packets before they reached the web server at all.
That’s the key advantage over an .htaccess block: banned traffic never touches Apache.

A VPS with limited resources can’t absorb a flood of uncached requests. Caching helps with repeat visits to the same page, but an attacker who rotates URLs defeats that entirely. Fail2Ban shifts the defence from the application layer down to the network
layer, where it’s cheap to enforce.

If you run a small site on a VPS, configure fail2ban for your web server. It takes ten minutes and it works.

Anyway, I presume whoever did that attack is reading this post since they seem to like my blog so much. Why did you do it?

Ich würde gerne den neuen Server und die etwa 15 Webseiten, die darauf umziehen ausschließlich auf IPv6 umstellen. Spricht da etwas dagegen? Sollte ich beides ermöglichen? Oder nur IPv4, wie bisher?

Vous avez déjà utilisé mod_evasive (Apache2) ? Je suis un peu dubitatifve devant cet outil. Il n’est pas listé dans la documentation officielle et je n’ai aucune idée de si c’est un module tiers et lequel est le plus fiable parmi les différents forks… Quant à comment le configurer, ça me semble un peu bancal 😅 ? Zéro idée de comment mon chef l’a installé et "configuré", sinon ce ne serait pas drôle 🙃 !

33 Debian LTS Advisories fixing 216 CVEs for various packages were released by Debian LTS contributors in January 2026. These include notable security updates for python 3.9, django 2.2.28, php 7.4, apache2, ceph, Linux 6.1 kernel and more.

A study into the security status report of p7zip, which is unmaintained upstream, was also done last month in addition to updates contributed for recent releases of Debian 12, Debian 13 and to Debian unstable.

Người dùng Debian 13 (Trixie) đang gặp khó khăn khi thiết lập ruTorrent do `mod_scgi` không còn sẵn có trong Apache2/PHP 8.4. Lỗi này khiến lệnh kết nối `SCGIMount /RPC1 127.0.0.1:5001` không hoạt động.

Đây là thách thức mới cho cộng đồng self-hosted khi các bản phân phối Linux cập nhật phần mềm và loại bỏ các module cũ.
