Tagged vs Untagged Ports: VLAN Configuration

TCP/IP goal (1970s): “Any host can talk to any host.” Blockwidth goal (2020s): “Any intent-carrying signal can arrive predictably enough to keep independent machines in better sync and coordination.”

Spy Event Processor: - Validate your payload, variables, attributes before and after a flows or in processors - Won't modify the event - Use to verify your logic before and the result after a call

What is a Patch Panel? A patch panel is a device with multiple ports that helps organize and connect network cables in a structured way. Instead of plugging all devices directly into a switch, cables first connect to the patch panel. 🔹 Organizes cables neatly → keeps setup clean and professional 🔹 Protects switch ports → reduces wear and tear from constant plug-ins 🔹 Easier cable tracing → quickly find which device is connected where 🔹 Adds flexibility → simple to manage changes without touching the main switch Keeping your network organized, secure, and easy to manage is what a patch panel is all about.

Which modification reduces NAT-induced hotspots without introducing application-layer stickiness? Reworded to avoid ambiguity around cookie-based sessions. A) Include ports & protocol in the key (5‑tuple hashing). B) Switch to Round Robin with no hashing. C) Use static weights on backends. D) Enable EWMA latency weighting.

zeropod is a tool that automatically checkpoints containers to disk after a certain amount of time of the last TCP connection, allowing for fast and seamless scaling down to zero. More: https://ku.bz/4gcszQMbG

PSA: Don’t plug into these. Two non–tamper-resistant screws and exposed USB ports? That’s a classic setup for “juice jacking”, where a compromised port can exfiltrate your data or infect your device. If you must use public USB, at least carry a data blocker. Better yet, plug into AC with your own adapter.

Every new TCP connection = 3-way handshake overhead. Keep-Alive keeps the connection open, skipping the repeated setup → faster requests, lower latency. 🚀"

Fiber builds are booming. Your network is growing. But can you say the same about your cable labels? If your team’s still manually tracing wires like it’s a treasure hunt… it’s time for an upgrade. Enter Panduit’s RapidID: ✨ Pre-labeled cables ✨ Barcode scanning magic ✨ Racks mapped in minutes No more guesswork. No more “what does this plug into again?” Just scan, connect, done. Don’t let your network fall victim to label laziness. Learn more: https://okt.to/2sPwCS

ICYMI: Say goodbye to combing through CAD as seconds tick by during a critical emergency. Introducing related incidents, a new feature within the Prepared platform that gives telecommunicators instant context on every prior & active incident relating to a call.

Some creative ways to check port status in Nmap! "These scan types rely on setting TCP flags in unexpected ways to prompt ports for a reply. Null, FIN, and Xmas scan provoke a response from closed ports, while Maimon, ACK, and Window scans provoke a response from open and closed ports."
