The simplicity and complexity of using quotes on Linux

There are only a few special characters involved in working with character strings on the command line or in a script on Linux: the single quote, the double quote and the backslash. But the rules aren’t as obvious as one might think. In this post, we’ll look at the easy and the somewhat tricky uses of these special characters.Echoing text The echo command doesn’t require any variety of quote characters much of the time.

Enterprise adoption of smartNICs faces challenges

Growth in hyperscaler data centers and processor-intensive enterprise workloads, such as high-performance computing (HPC) and AI, is set to drive broadscale adoption of SmartNICs.The Ethernet controller and adapter market will grow from $3.2 billion in 2021 to $5 billion in 2026, with smartNICs contributing significantly to the growth, according to Dell’Oro Group. In addition, server network connectivity will transition to higher speeds, according to the research firm, which predicts 100 Gbps and higher-speed ports will account for 44% of the shipments in five years.To read this article in full, please click here

HPE Slingshot Makes The GPUs Do Control Plane Compute

In modern system architecture, there is a lot of shifting pieces of systems software (particularly in the control plane) and often their workloads around between pieces of silicon to get better bang for the buck, to improve the overall security of the system, or both. …

Using the watch command on Linux

Watch is a command on Linux that will repeatedly run commands for you, and it offers some very useful options. One of its basic options is that you can tell watch how long to wait before running the specified command again. For example, if you run the command watch -n 10 date, the watch command will first clear the screen and run the date command right away. After that, it will run the command every 10 seconds until you stop it by hitting control-C. Note that the first line on the screen will indicate the wait time between iterations (every 10 seconds).$ watch -n 10 date Every 10.0s: date fedora: Fri, Aug 12 16:32:09 EDT 2022 Fri Aug 12 04:10:11 PM EDT 2022 The -n option specifies the number of seconds between commands. The default is 2. You might have to look closely to notice the changes in the output.To read this article in full, please click here

BGP Peering (2)

I recorded the beginnings of a BGP training series over at Packet Pushers a short while back; they’ve released these onto youtube (so you can find the entire series there). I’m highlighting one of these every couple of weeks ’til I’ve gone through the entire set of recordings. In this recording, I’m talking through some more interesting aspects of BGP peering, including challenges with IPv6 link local nexthops, promiscuous peering, and capabilities.

VMware NSX Achieves Common Criteria Certification for Network Devices (NDcPP 2.2e)

We are excited to share that as of July 2022, VMware NSX-T version 3.1 has passed Common Criteria certification for Network Devices under Collaborative Protection Profile 2.2e, also known as NDcPP 2.2e. This is one of many testaments to our commitment to providing industry-leading certified solutions for customers from federal departments and agencies, international governments and agencies, and other highly regulated industries and sectors. Along with FIPS, DISA-STIG, ICSA Labs firewall certification, and several other independent evaluations, the NDcPP 2.2e certification validates NSX as a reliable network virtualization platform that satisfies rigorous government security standards.

VMware NSX 3.1 is now listed:

From the NIAP Security Evaluation Summary:

The evaluation was carried out in accordance with the Common Criteria Evaluation and Validation Scheme (CCEVS) process and scheme. The criteria against which the VMware NSX-T Data Center 3.1 was evaluated are described in the Common Criteria for Information Technology Security Evaluation, Version 3.1 rev 5.  The evaluation methodology used by the evaluation team Continue reading

Jumping Off Cliffs

For quite a few years, I’ve had this desktop wallpaper that I really love. I don’t even remember where I got it or where it came from, so I can’t properly attribute it to anyone. I use this wallpaper from time to time when I want to be reminded to challenge myself, to learn new things, and to step outside of what is comfortable in order to explore the as-yet-unknown. Looking at this wallpaper on my desktop a little while ago, I realized that I may have started taking the inspirational phrase on this wallpaper for granted, instead of truly applying it to my life.

Here’s the wallpaper I’m talking about:

A person jumping off a cliff, with the text “We have to continually be jumping off cliffs and developing our wings on the way down”

To me, this phrase—illustrated so well by the wallpaper—means taking a leap into the unknown. It means putting yourself into a position where you are forced to grow and adapt in order to survive. It’s going to be scary, and possibly even a bit painful at times. In the end, though, you will emerge different than when you started.

It’s been a while since I did that, at least from a career perspective. Yes, I did change jobs a little over a year ago when I left VMware to Continue reading
