Worth Reading: Agile Development and Security

Matthias Luft (a good friend of mine, and a guest speaker in the upcoming Building Next-Generation Data Center course) wrote a great post about the (lack of) security in software development.

The parts I like most (and they apply equally well to networking):

The Linux Migration: Other Users’ Stories, Part 2

This post is part of a series of posts sharing the stories of other users who have decided to migrate to Linux as their primary desktop OS. Each person’s migration (and their accompanying story) is unique; some people have embraced Linux only on their home computer; others are using it at work as well. I believe that sharing this information will help readers who may be considering a migration of their own, and who have questions about whether this is right for them and their particular needs.

For more information about other migrations, see part 1 or part 2 of the series.

This time around we’re sharing the story of Rynardt Spies.

Q: Why did you switch to Linux?

In short, I’ve always been at least a part-time Linux desktop user and a heavy RHEL server user. My main work machine is Windows. However, because of my work with AWS, Docker, etc., I find that being on a Linux machine with all the Linux tools at hand (especially OpenSSL and simple built-in tools like SSH) is invaluable when working in a Linux world. However, I’ve always used Linux Mint, or Ubuntu (basically Debian-derived distributions) for my desktop Continue reading

iPhone 8 Rumor Rollup: new Lightning twist; Apple getting schooled; delivery delay?

Despite the fact that Apple had no presence at the big Mobile World Congress event in Barcelona this past week, rumors about the iPhone 8 or iPhone X did not subside.Sure, Android and Windows had their week in the spotlight at MWC, but inquiring minds also wanted to know what's up with rumors about a possible new port on the next flagship iPhone.LIGHTNING FAST CHARGING The Wall Street Journal and others reported that a USB Type-C port might be coming to the iPhone 8 to deliver faster charging and data transfer speeds. But by the end of the week, in part because of commentary from KGI Securities analyst Ming-Chi Kuo (revealed by MacRumors), the consensus seemed to be that the USB Type-C connecter will indeed come to the next iPhone, but on the other end of the cord from the Lightning connector. That's similar to what you find in the 12.9-inch iPad Pro.To read this article in full or to leave a comment, please click here

Ransomware attack hit Pennsylvania Democratic senators

The Pennsylvania Senate Democratic Caucus was hit with a ransomware attack, locking 16 Democratic senators and their staff out of their computer network.The attack was discovered on Friday morning; at the time of publishing, the Pennsylvania Senate Democratic Caucus website was still down and displayed an “error establishing a database connection” message. The same error displays when trying to view each Democratic senator’s website.“Officials from the caucus have been in contact with law enforcement to investigate the incident and are working with Microsoft to restore the IT system,” according to a written statement text-messaged to reporters and obtained by The Hill. It was sent via text, since the caucus could not use its email. “There is currently no indication that the caucus system was targeted or that any data has been compromised.”To read this article in full or to leave a comment, please click here

Netops with Emacs and Org mode

Org mode is a package for Emacs to “keep notes, maintain todo lists, planning projects and authoring documents”. It can execute embedded snippets of code and capture the output (through Babel). It’s an invaluable tool for documenting your infrastructure and your operations.

Here are three (relatively) short videos exhibiting Org mode use in the context of network operations. In all of them, I am using my own junos-mode which features the following perks:

• syntax highlighting for configuration files,
• commit of configuration snippets to remote devices, and
• execution of remote commands.

Since some Junos devices can be quite slow, commits and remote executions are done asynchronously¹ with the help of a Python helper.

In the first video, I take some notes about configuring BGP add-path feature (RFC 7911). It demonstrates all the available features of junos-mode.

In the second video, I execute a planned operation to enable this feature in production. The document is a modus operandi and contains the configuration to apply and the commands to check if it works as expected. At the end, the document becomes a detailed report of the operation.

In the third video, a cookbook has been prepared to execute Continue reading

NSX-V 6.3: Control Plane Resiliency with CDO Mode

NSX-V 6.3, released last month, introduced many new features. In my last blog post, NSX-V 6.3: Cross-VC NSX Security Enhancements, I discussed several new Cross-VC NSX security features. In this post I’ll discuss another new feature called Controller Disconnected Operation (CDO) mode which provides additional resiliency for the NSX control plane.

The NSX Controllers already offer inherint resiliency for the control plane by design in several ways:

• complete separation of control plane and data plane (even if entire controller cluster is down, data plane keeps forwarding)
• controller cluster of three nodes allows for loss of controller with no disruption to NSX control plane
• vSphere HA provides additional resiliency by recovering the respective NSX controller on another node if host it’s running on fails

For the reasons mentioned above, it’s a rare event and unlikely that communication would be lost with the entire NSX Controller Cluster. In NSX-V 6.3, this control plane resiliency is enhanced even further via CDO mode.

CDO mode targets specific scenarios where control plane connectivity is lost, for example, a host losing control plane connectivity, losing control plane connectivity to the controller cluster, or NSX controllers are down. CDO mode enhances control plane Continue reading

IDC projects Windows Phone share to be big fat goose egg by 2021

Market watcher IDC anticipates the worldwide smartphone market will bounce back over the next few years from a sluggish 2016, but Microsoft is not expected to take part in that celebration.In fact, while Android smartphone shipments are projected to edge up from 85% this year to 85.3% in 2021 and Apple iPhones are expected to slip a tad from 14.7% to 14.6%, Windows Phone's meager 0.1% share in 2017 will drop to 0% if IDC is on the mark.While Windows Phone's predecessor, Windows Mobile, led the U.S. market as recently as 10 years ago, iOS and BlackBerry blew by it before long in the United States, and Symbian ruled worldwide until its own decline beginning in 2011.To read this article in full or to leave a comment, please click here

Uber and the Terrible, Horrible, No Good, Very Bad Month

On February 19th, this year, Susan J. Fowler, a software engineer who left Uber (I don’t have to explain what Uber is, do I?) to work for Stripe (okay, I’ll outline what they are: Stripe has been described as “the PayPal of the mobile era”) blogged about her experience of working at Uber. She outlined a nightmarish corporate culture of poor management, backstabbing, dirty politics, and negligent human resources, along with apparently endemic and rampant sexual discrimination and harassment. To read this article in full or to leave a comment, please click here

Enough with “the Cyber”!

Email is great; it’s transformed business, enabled geographically dispersed families and friends to stay in touch, redefined news distribution, transformed sales pipelines … the list of good stuff about email is endless. But, as many people have discovered to their cost, keeping control of your email account requires effort, effort like not using dumb, easy-to-guess passwords, and making sure your email hosting service is reliable and not, for example, Yahoo or AOL. And these issues aren’t anything like new, recent discoveries; we’ve all known for over a decade where the risks lie … well, all of us except, apparently, for the government.I don’t know about you, but  during the 2016 election I was fairly surprised when the Democratic National Committee email system was hacked after which the email account of John Podesta, the DNC chairperson, was hacked. You’d have thought that the folks who manage IT for these people would have known the risks and done more to minimize exposure but when simple phishing and malware intrusions that should never of happened and which went undetected were successful, then you have to wonder where the disconnect lies.To read this article in full or to leave a comment, Continue reading

Container networking: What is it and how can it help your data center?

There has been a lot of buzz in the industry about containers and how they are streamlining organizational processes. In short, containers are a modern application sandboxing mechanism that are gaining popularity in all aspects of computing from the home desktop to web-scale enterprises. In this post we’ll cover the basics: what is container networking and how can it help your data center? In the future, we’ll cover how you can optimize a web-scale network using Cumulus Linux and containers.

What is a container?

A container is an isolated execution environment on a Linux host that behaves much like a full-featured Linux installation with its own users, file system, processes and network stack. Running an application inside of a container isolates it from the host and other containers, meaning that even when the applications inside of them are running as root, they can not access or modify the files, processes, users, or other resources of the host or other containers.

Containers have become popular due to the way they simplify the process of installing and running an application on a Linux server. Applications can have a complicated web of dependencies. The newest version of an application may require a newer Continue reading

Gigamon CMO Steps Down, Sales Leadership Reorganizing

Fred Studer's CMO tenure lasted less than a year.

Trump broke his H-1B promise. Now what?

On the campaign trail, candidate Donald Trump was so determined to present himself as the solution to H-1B visa abuse – the kind that has American IT workers training their foreign replacements -- that he promised to launch an investigation of the program on day one of his administration. Not in due time, on day one. Today is day 43. No investigation has been launched. No changes have been made to the H-1B program. And it’s not clear when or if any will be forthcoming. That no one should be surprised does not mean no one has taken notice. From a Computerworld story:To read this article in full or to leave a comment, please click here

IoT and 5G are driving computing to the edge

By 2020, an average internet user will use 1.5GB of traffic a day, and daily video traffic will reach 1PB, Intel predicts. A huge amount of data will be generated by autonomous vehicles, mobile devices, and internet-of-things devices.Every day, more information is being collected and sent to faster servers in mega data centers, which analyze and make sense of it. That analysis has helped improved image and speech recognition and is making autonomous cars a reality.Emerging superfast data networks like 5G -- a melting pot of wireless technologies -- will dispatch even more gathered information, which could stress data centers. Servers are already being redesigned to handle more data, and throughput technologies like Gen-Z and fiber optics will reduce latency.To read this article in full or to leave a comment, please click here
