Mitigating a DoS attack with GoAccess and Cloudflare

In this off-topic post, I’m going to discuss some behind-the-scenes “fun” that may happen when managing the web server used to host the CNX Software website. From time to time, the server becomes unreachable, but I can still access its console, and notice a very high CPU load (over 100) on a VPS with four cores, while the CPU load is typically 0.5 to 2 under normal circumstances. That’s usually due to a DoS (denial of service), DDoS (distributed denial of service), or some bug I can’t identify. An easy way to solve this issue is to log in to Cloudflare and set the “Under Attack Mode” to on. It will show all visitors a JavaScript challenge the first time they visit the website, and the CPU usage typically drops back to normal level within a minute or so. That means I can access my website and so do regular […]

ASUSTOR Flashstor Gen2 NAS features AMD Ryzen Embedded V3C14, 10GbE networking, up to 12x NVMe SSD sockets

ASUSTOR Flashstor 6 Gen2 and Flashtor 6 Pro Gen2 are NAS systems based on AMD Ryzen Embedded V3C14 quad-core processor with up to two 10GbE RJ45 ports and taking up to 6 or 12 M.2 NVMe SSDs respectively. The Flashstor Gen2 models are updated to the ASUSTOR Flashtor NAS launched last year with similar specifications including 10GbE and up to 12 M.2 SSDs, but based on a relatively low-end Intel Celeron N5105 quad-core Jasper Lake processor. The new Gen2 NAS family features a more powerful AMD Ryzen Embedded V3C14 SoC, support for up to 64GB RAM with ECC, and USB4 ports. The downside is that it lacks video output, so it can’t be used for 4K/8K video consumption like its predecessor. Flashstor Gen2 NAS specifications: SoC – AMD Ryzen Embedded V3C14 quad-core/8-thread processor @ 2.3/3.8GHz; TDP: 15W System Memory Flashstor 6 Gen2 (FS6806X) – 8 GB DDR5-4800 Flashstor 12 Pro […]

Black Friday and Cyber Monday 2024 – International deals and coupons

While Black Friday and Cyber Monday used to be a US-only event, it changed many years ago, and we’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, since a large portion of our audience cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events that will take place from November 21 until December 2 this year. So I’ve gathered some international Black Friday and Cyber Monday 2024 deals and discount coupon codes from relevant manufacturers and popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress’ Black Friday and Cyber Monday 2024 event has already started.
