NETWORKING

Back when I started as a network engineer, we didn’t even have wireless networks.  All of our clients were hardwired.  In fact, because I was in charge of network security, I remember being firmly opposed to introducing wireless onto my network!  Those days are obviously long gone, but one thing hasn’t changed–even with hardwired clients, I  managed an open-source IPS system to detect attacks against my network, malware, and other threats. I recently sat down…

The which, whereis and whatis commands on a Linux system provide information about commands. They provide related but not identical information. In this post, we’ll check out the differences and provide a script for getting information that’s available from all three commands. We’ll also explore some sample commands for looking at secondary (i.e., not section 1) man pages. which The which command will show you the file-system location for a command’s executable. This is the…

Today, the need for security is at an all-time high. Huge, high-profile ransomware attacks hit the news all too often, so it’s not a surprise that cybersecurity pros are trying everything to secure their networks. Many people frantically buy every new solution out there but throwing multiple point products at the problem isn’t the answer. Too many products inevitably lead to too much complexity. Managing multiple vendors and products with little integration or coordination can…

Cisco has added a new class of servers to its Unified Computing System that are more flexible and outfitted with management software geared to hybrid cloud. The UCS X-Series is the first major redisign since UCS hit the market in 2009. The company says the modular hardware architecture is future-proofed because it can accomodate new generations of processors, storage, nonvolatile memory, accelerators, and interconnects as they come along. Prior UCS chassis were either blade systems…

Data center capacity has historically been a technology concern focused on compute, storage, and power resources. But it now has a fourth vector: Humans. IT specialists are in extremely high demand and disconcertingly short supply. They’re responsible for an increasingly complex mix of infrastructure and applications, which in many cases have branched beyond the data center and are now distributed among cloud, colocation, branch office, and edge environments. And more than ever, technologists have been…

We’ve all seen how the pandemic has changed the way state and local governments work and how they’re delivering services to the people of their communities. We’ve also watched as it accelerated changes in the public sector workplace, impacting which technologies are adopted—and how they’re used—the effects of which will be felt for decades. People call it the “next normal” but the truth is it’s long overdue. The future of work is now here. It’s…
