DNS Queries Made Easy: dig, host, and nslookup Explained: Why DNS Queries Matter for Anyone Running a Server Let’s be honest: DNS is one of those things you don’t think about until something breaks. Suddenly, your shiny new VPS or Dockerized app isn’t reachable, your emails bounce, or your domain points to the wrong place. If you’re running anything from a basic website to... https://mangohost.net/blog/dns-queries-made-easy-dig-host-and-nslookup-explained/?utm_source=dlvr.it&utm_medium=mastodon #blogpost #networking

Modern high-speed Ethernet standards often use optical transceivers to transmit data over long distances via fiber optic cables. These transceivers are essential in data centers, enterprise networks, and carrier infrastructure where copper cabling is insufficient for speed or distance requirements
Here are different types of optical transceivers 😎👇 #datacenters #sysadmin #technology

Kubernetes Networking with Cilium: eBPF-Based Observability and Security: Why Kubernetes Networking is a Headache? If you’ve ever tried to set up a Kubernetes cluster—whether on a cloud provider, your own VPS, or a beefy dedicated server—you’ve probably run into networking weirdness. Pods can’t talk to each other. Services are unreachable. Network policies don’t work as expected. And, when you try to debug, it’s... https://mangohost.net/blog/kubernetes-networking-with-cilium-ebpf-based-observability-and-security/?utm_source=dlvr.it&utm_medium=mastodon #blogpost #networking

Recently switched from arch to #nixos and encountering a strange networking issue where network over wifi drops out every ~30 seconds or so. Very occasionally had problems on arch but nothing this bad.
Have been enjoying getting to grips with #networking but this one is particular annoying.
I stared at tcpdump for awhile but couldn't make much sense of output.
NIC is an Intel Killer AX1650w. Delightful wifi setup in my rental is behind an extender.
Anything obvious I can check?

Woah- WiFi is such a vulnerable point in any network. I see why backups are so important.
Playing around with the home system has been quite interesting. Also 2.4ghz is actually so fucking insane 😭

I am looking for some kind of VM or system I can run to create a network that I can put an untrusted device on to and allow/deny all its connections one by one - think auditioning a new TV or IOT device rather than out-and-out hostile malware. Assume I will also dump packets for investigation.
Security Onion looks like overkill but I'd like to avoid writing my own firewall rules if possible.
