Everything Is Better with a GUI (even netsim-tools)

Some people think that everything is better with Bluetooth. They’re clearly wrong; according to the ancient wisdom of product managers working for networking vendors, everything is better with a GUI.

Now imagine adding network topology visualizer and GUI-based device access with in-browser SSH to an intent-based infrastructure-as-code virtual network function labbing tool. How’s that for a Bullshit Bingo winner¹?

Creating a quick calculation function on Linux

Anytime you're planning to do a lot of calculations on a Linux system, you can use the power of bash to create a quick function and then use it repeatedly to do the calculations for you. In this post, we'll look at how this trick works and what you need to be aware of to ensure that your calculations are correct.Let's start with this mathematical function as an example:$ ? () { echo "$*" | bc ; } Troubleshooting your bash scripts in Linux   This command sets up a function that will pass the values and mathematical operators that you provide as arguments to the bc calculator command. Note that to call the function, you simply type a "?" followed by the arguments. In the first example below, the arguments are 1, followed by the multiplication character "*", followed by a 2, a "+" sign and a 3. The result is 5.To read this article in full, please click here

How SASE uses AI

Secure access service edge, or SASE, combines networking and security into a cloud-based service, and it’s growing fast. According to Gartner projections, enterprise spending on SASE will hit almost $7 billion this year, up from under $5 billion in 2021. Gartner also predicts that more than 50% of organizations will have strategies to adopt SASE by 2025, up from less than 5% in 2020.To read this article in full, please click here

What is Ethernet?

Ethernet is one of the original networking technologies, having been invented nearly 50 years ago. And yet, because of the simplicity by which the communications protocol can be deployed and its ability to incorporate modern advancements without losing backwards compatibility, Ethernet continues to reign as the de facto standard for computer networking.At its core, Ethernet is a protocol that allows computers (from servers to laptops) to talk to each other over wired networks that use devices like routers, switches and hubs to direct traffic. Ethernet works seamlessly with wireless protocols, too.Its ability to work within almost any environment has led to its universal adoption around the world. This is especially true because it allows organizations to use the same Ethernet protocol in their local area network (LAN) and their wide-area network (WAN). That means that it works well in data centers, in private or internal company networks, for internet applications and almost anything in between. It can even support the most complex forms of networking, like virtual private networks (VPNs) and software-defined networking deployments.To read this article in full, please click here

Mitigate Supply-Chain Attacks With Microsegmentation And ZTNA

This article originally appeared on Packet Pushers Ignition on January 12, 2021. In broad terms, the SolarWinds attack is a standard (though well-executed) supply-chain compromise that breaches a trusted source of software, hardware, or services to gain entry into an organization’s internal infrastructure. Once inside, it spreads to other systems, installs additional tools, compromises user […]
