Hello and welcome to the Unrayed April Digest. I'm your host, Stefanopartina, and today we're gonna talk about all things that went down in April. With our first topic, I'm sure all of you have heard this by now because all of the buzz has been generated online and pretty much everyone talking about it. And if you haven't heard, well, uh good job, I guess. But 45 Home Lab and Lime Technology, the creators of Unraid, have released their new X15 server. This is a jointly engineered server designed to meet the needs of the most common Home Lab use cases and be as flexible as possible. The CPU chosen for the X15 is an Intel 14700, which has 20 cores and 28 threads. It also has an IGPU. This is a good choice because it has plenty of room for virtual machines and or containers, and can also support transcoding for streaming services. No dedicated GPU is required, which reduces costs, frees up a PCIe slot, and reduces the system's power consumption overall. A workstation motherboard was chosen for this build because it offers things that consumer motherboards cannot, like supporting ECC memory, A-speed BMC for full remote IPMI, out-of-band management and troubleshooting, an onboard speaker that is also useful for troubleshooting, four PCIe Gen 4 M.2 slots, eight SATA ports, dual PCIe Gen 5 slots, an M.2 E key for Wi-Fi, 128GB capacity across the four DEM slots, and an Intel 2.5 GB Ethernet port. This is genuinely a great pick for a motherboard because it is so well rounded and can be applied to many use cases. If the onboard 2.5 GB Ethernet isn't fast enough for you, this system also comes with an Intel X550 T2, which is a dual 10GB Ethernet NIC. On the storage front, we are given the most trusted and heavily regarded LSI 9400 HBA card as a storage controller. The X15 will have 16GB of DDR4 ECC memory, which will help defend against data corruption and improve system reliability. There is a 1TB Kingston NVMe boot drive that will store the Unraid OS itself, so no SD card or USB stick is required. Oh and by the way, the X15 includes an Unraid lifetime license, so that means there's no expiration, there's no subscriptions, and there are no fees. Lastly, the X15 comes with a trustworthy and fully modular Corsair 1000 watt 80 plus gold rated power supply, which will give you plenty of headroom in the future for dedicated GPU expansion, and it will also run silently and quietly. Speaking of quietly, the included Arctic P12 Pro fans will provide maximum airflow to keep things cool all the while being silent enough for your home or office. Unrate 7.3 release candidate 1 is now generally available, and this release candidate brings us better onboarding, internal boot support, TPM-based licensing, Docker and storage improvements, web UI improvements, virtualization updates, hardware support, and platform package updates. Before you run off and install the release candidate 1, be sure to visit the blog page to learn about known issues, considerations for rolling back, and how to report bugs should you discover them. Unraid OS 7.2.5 is available and it's recommended that everyone apply this update because it brings us some security patches as well as bug fixes for things like Docker, the web UI, and so forth. The Linux kernel is updated to patch two vulnerabilities. One that is the copy fail, local privilege escalation vulnerability, that affects nearly every distribution of Linux and has existed since 2017. This vulnerability allows tackers to gain valuated privileges on a system which would potentially allow them to take full control of it. Another fix is for a trigger by unprivileged users submitting specially crafted X509 certificates to the kernel, which could cause the kernel memory to leak contents, crash the system, and even potentially gain escalated privileges. Docker has been updated to version 29 to fix three significant security vulnerabilities with Run C. Docker Engine 28 introduced new functionality that dynamically generates MAC addresses each time a container is created. So any containers that rely on stable MAC addresses for DHCP reservations, firewall rules, ACLs, or monitoring will be affected by this after the upgrade is applied. The MAC address field is now included in Docker templates. So values set here are preserved across Docker restarts or reboots. Any templates that used extra parameters for MAC addresses will automatically be migrated to include this new field. Oh, and uh you guys should honestly apply unrate 7.2.5 because there are so many fixes and CVs that are resolved. So take this one very seriously. For the app of the month, we have custom SMB shares, which really gives you a ton of granularity in controlling your SMB shares. I highly recommend just checking out the video instead of relying on me to relay information to you because there is just so much granularity you have with this app. Be sure to check out the Unrayed Digest page to see community content from around the web. And also be sure to check out Alien Tech 42's YouTube video about Cloudflare tunnels versus Nginx. I have watched it and it is absolutely clear, concise, and packed full of tons of information that I think you all will find very valuable. Before I let you go, don't forget to check out the merch store and of course like and subscribe if you enjoy content like this. Thank you all for watching and good night.
