Troubleshooting NTP With Wireshark

 

Troubleshooting NTP With Wireshark

Many of my regular customers refer to me as the ‘Network Janitor’ because I seem to gravitate to ‘cleaning up’ networks.

In some cases, yes physically cleaning up and organizing datacenters, wiring closets, etc – kind a network version of a personal organizer. In most cases though I clean up the network from the packet perspective.

For years I have been preaching concepts such as ‘The pc bootup and login baseline’ as well as “The VLAN or subnet broadcast analysis”. In both cases, I look for unnecessary traffic to make things run smoother and more efficiently.

In my throughput class I explain how quickly things get messy using basic math. For example, assume you have a 7% broadcast rate on switch where everybody has a 1 Gbps connection.

Documenting Why “Its Slow”

I can’t tell you how many times I have heard that dreaded phrase, “Its Slow”.  I’ve heard this so many times I typically casually respond with, “Great, what is it and how slow is slow?”   The biggest issue I have with this statement is that this is the typical network complaint that sucks you into the troubleshooting vortex since nothing is clearly defined.   For example, if I said, “email is slow or it takes 2 hours to download my files” you have a chance to address this since I can measure the problem and the end result. The 2 hour comment actually gives you a measurable value to compare against.   One of the toughest things about troubleshooting is when an assumption is made like drive x on the server is fine, therefore the server is fine.   In this example I wanted to demonstrate to a client that one disk or file system on a server can be slower than the other. I also taught him some Wireshark tips and tricks along the way to help him in the future.   Enjoy

One More Thing (Paul W. Smith )

One More Thing (Paul W. Smith )

 

Everyone loves a good saying.  Aphorisms – those terse statements instilled with a modicum of truth – are a popular part of our language.  The term originated with Greek physician Hippocrates who once aphorized, “To do nothing is sometimes a good remedy.”  Ironically, he is also regarded as the Father of Medicine.  The more aphorisms are used, the more credibility they accrue.  

It is widely known that actions speak louder than words, he who hesitates is lost, and if you lie down with dogs, you wake up with fleas.  It is reassuring that a barking dog never bites, and that absence makes the heart grow fonder.

Create a Wireshark Auto‑Capture Shortcut: Instant Packet Sniffing on Launch

Create a Wireshark Auto‑Capture Shortcut: Instant Packet Sniffing on Launch

In this video, I show you how to streamline your workflow in Wireshark by creating a Windows desktop shortcut that launches the program and immediately begins capturing packets. Instead of navigating menus or manually starting a capture each time, the tutorial walks you through a simple command‑line tweak that transforms Wireshark into a one‑click network analysis tool. It’s a small optimization with a big impact, especially if you frequently monitor network traffic.

Next Generation Autonomous Control - Dynamic Artificial Intelligence DAI (Mr. Lenko)

Next Generation Autonomous Control - Dynamic Artificial Intelligence DAI (Mr. Lenko)

 Real-time autonomous control for distributed and edge devices using a hybrid of real-time Neural Networks, Inference Engines, and Evolutionary Computational Structures.

Abstract

Dynamic Artificial Intelligence (DAI™) is a new technology originated by Xtensor Systems to develop and integrate next-generation autonomous systems. DAI™ enables real-time control of distributed edge devices, remote locations, and distributed equipment without the need for a centralized control system or cloud data sets. DAI™ creates secure Autonomous applications that respond dynamically to changing local conditions. The system provides Autonomy by switching from one neural net or inference engine configuration to another in real-time.


What is Autonomous Control?

Autonomous control solutions include products, systems, and services that respond autonomously with specific actions without human interaction. In general, they are a combination of proprietary automation, control, sensing, and AI technologies. The technology utilization is still early-stage with initial applications including military vehicles (land/sea/undersea/air) and commercial vertical solutions (automobile, robotics, and more). Autonomy promises to create better, faster, and cheaper commercial solutions.


What is Missing from Current Autonomous Solutions?

Before Autonomous solutions can takeoff commercially, several issues need resolution:

Scalability

AI requires expertise to design and build integrated solutions

AI Complexity

Limited AI expertise in the market – early-stage market

Real-time Capabilities

Edge solutions require local real-time response

Distributed Functionality

Complex integration when distributing functionality

Security

Data, communications, and cybersecurity vulnerabilities

Long Lead Times

Long lead times until solutions are fully functional

Adds, Moves, Changes

Variability requires constant solution modifications


What is Dynamic Artificial Intelligence

Dynamic Artificial Intelligence™ (DAI™) is Xtensor’s patented autonomous control software that powers the next generation of secure, highly intelligent Edge devices, products, systems, and services. It is a complementary technology designed to integrate control solutions with management solutions more quickly. DAI™ technology brings high-performance and high scalability to distributed applications without producing heavy network traffic. DAI™ pre-optimizes system processes with minimal human intervention. DAI™ can be reconfigured, updated, and upgraded remotely for servicing and support. DAI™ proactively responds to problems and threats in 10 milliseconds. Complex Edge challenges can be resolved automatically in less than one second instead of hours or days using existing solutions.


Why DAI™?

DAI™ introduces new Autonomous capabilities into the changing control and management markets. DAI™ is a flexible platform that can migrate existing solutions into the future. It can help transform existing products, systems, and services into leading-edge, fully Autonomous solutions.
