Beware the Marketing Magic of GUI-Based Programming

Someone working for a network automation startup desperately tried to persuade me how cool their product is. Here’s what he sent me:

We let network engineers build their own network automation solutions in no time without requiring coding or scripting knowledge. It’s all GUI based, specifically geared towards network engineers - they can simply model services or roll-out networks “as-designed”.

The only problem: I’ve seen that same argument numerous times…

Wow: NVMe and PCIe Gen 4

Recently it’d come to my attention that my old PC rig wasn’t cutting it.

• Intel i7 950
• 18 GB of RAM
• X58 Asus-based motherboard
• Sandisk 1 TB SSD
• 2 x 8 TB Shucked Best Buy Easystore Hard Drives in Windows Storage Spaces (see why I didn’t do parity storage because of the Microsoft shit-show)
• 1 Gigabit Intel NIC
• NVidia GTX 980

Considering it was 10 years old, it was doing really well. I mean, I went from HDD to 500 GB SSD to 1 TB SSD, up’d the RAM, and replaced the GPU at least once. But still, it was a 4-core system (8 threads) and it had performed admirably.

The Intel NIC was needed because the built-in ASUS Realtek NIC was a piece of crap, only able to push about 90 MB/s. The Intel NIC was able to push 120 MB/s (close to the theoretical max for 1 Gigabit which is 125 MB/s).

The thing that broke the camel’s back, however, was video. Specifically 4K video. I’ve been doing video edits and so forth in 1080p, but moving to 4K and the power of Premerier Pro (as opposed to iMovie) was just killing my system. 1080p was a Continue reading

3 strategies to simplify complex networks

As the cloud era meets the demands of digital transformation, networks must change. That means for enterprises, they must become simpler, said Juniper CEO Rami Rahim, speaking at the company's annual industry analyst conference last week.The past five years has seen more innovation in networking than in the previous 30. Things such as SD-WAN, multi-cloud, Wi-Fi 6, 5G, 400 Gig, and edge computing are on the near-term horizon for almost every company. While all of those technologies have enabled the network to do so much more than ever before, their complexity has also risen.To read this article in full, please click here

How to freeze and lock your Linux system (and why you would want to)

How you freeze and "thaw out" a screen on a Linux system depends a lot on what you mean by these terms. Sometimes “freezing a screen” might mean freezing a terminal window so that activity within that window comes to a halt. Sometimes it means locking your screen so that no one can walk up to your system when you're fetching another cup of coffee and type commands on your behalf.In this post, we'll examine how you can use and control these actions. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] How to freeze a terminal window on Linux You can freeze a terminal window on a Linux system by typing Ctrl+S (hold control key and press "s"). Think of the "s" as meaning "start the freeze". If you continue typing commands after doing this, you won't see the commands you type or the output you would expect to see. In fact, the commands will pile up in a queue and will be run only when you reverse the freeze by typing Ctrl+Q. Think of this as "quit the freeze".To read this article in full, please click Continue reading

The Week in Internet News: Antitrust Investigations of Big Tech Heat Up

Playing monopoly: Antitrust investigations of large U.S. tech companies are launching, with 48 state attorneys general announcing a Google probe, Salon.com reports. The focus is on Google’s alleged domination of online advertising. Meanwhile, the U.S. House of Representatives Judiciary Committee has asked Facebook, Amazon, Apple, and Google parent company Alphabet to turn over documents in its own antitrust probe, CNBC.com says. The House committee seems to be focused on Facebook’s and Google’s recent acquisitions, Amazon’s promotion of its own products, and other issues.

Broadband Island: Anacortes, Washington, on Fidalgo Island near Seattle, is building its own broadband network, Geekwire.com notes. The city is using existing water lines to install fiber optic cable, and the service will cost residential customers $39 per month for 100 Mbps service and $69 for gigabit speeds. 

The Internet of Gasoline: Hackers are increasingly talking about ways to target Internet of Things connected gasoline pumps, ZDNet reports. It’s unclear whether hackers are targeting gas pumps as a way to get cheaper gas or for more destructive reasons. Smart electricity meters are also a target, with the goal of reducing bills, the story suggests.

Just Published: High-Level Azure Networking Concepts

Last week we started the Microsoft Azure Networking saga that will eventually mirror the AWS Networking materials.

I recorded the hands-on demos in advance so we had plenty of time to discuss Azure API and CLI, geographies, regions and availability zones, high-availability concepts, and deployments models… and spent the second half of the live session focusing on virtual networks, subnets, interface, and IP addresses. The videos are already online and accessible with Standard ipSpace.net Subscription.

Next step (on September 24th): network security and user-defined routes.

If You Travel to Slovenia, You SHOULD NOT Fly with Adria Airways

I apologize to my regular readers for a completely off-topic post, but if I manage to save a single traveller the frustrations I experienced a few weeks ago it was well worth it. Also, please help spread the word…

TL&DR: If you travel to Slovenia, DO NOT even consider flying with Adria Airways (and carefully check the code-share flights, they might be hiding under a Lufthansa or Swiss flight number). Their actual flight schedule is resembling a lottery, and while I always had great experience with the friendly, courteous and highly professional cabin crews, it’s totally impossible to reach their customer service.

WISP Design – Migrating from Bridged to Routed

TFW adding the 301st subscriber to your bridged WISP….

Why are bridged networks so popular?

• Getting an ISP network started can be a daunting task. Especially, if you don’t have a networking background.
• Understanding L1/L2/L3 is not easy – I spent a number of years working in IT before I really started to grasp concepts like subnetting, the OSI model and Layer 2 vs. Layer 3. It takes a while.
• Bridged networks are very attractive when first starting out. No subnetting is required and the entire network can be NATted out an upstream router with minimal configuration.

What does a “bridged” network look like?

• Bridged networks use a single Layer 3 subnet across the same Layer 2 broadcast domain (typically over switches and software/hardware bridges) which is extended to all towers in the WISP
• Bridging can be done with or without VLANs but they are most commonly untagged.
• The diagram below is a very common example of a bridged WISP network.

What is the difference between switching and bridging?

These days, there isn’t much difference between the two terms, switch is a marketing term for a multiport hardware-accelerated bridge that became popular in the 1990s to Continue reading
