IDG Contributor Network: Bad cell service? Just start your own telco

We've all enjoyed a good moan about our cellular phone service over the years. Iffy coverage, bizarre billing practices, and infuriating customer service have all provided a source of jovial dinner table chat in my home. As the expression goes: you've got to laugh or you'd cry.But our trials are nothing compared to what some people experience. Many in rural areas have no service at all.Those unfortunate souls have, until now, had no redress. When powerful telco won't provide service, you simply don't have service.However, in Mexico, that's changing. Just as individual citizens in some Mexican communities have bandied together to create their own prisons (due to a lack of them), citizens are also creating their own local cellular systems.To read this article in full or to leave a comment, please click here

Microsoft to integrate Skype, Office with Cyanogen’s version of Android

Microsoft’s mobile apps will be integrated into a future version of Cyanogen’s Android-based operating system, as CEO Satya Nadella steps up efforts to make the company’s software more popular on Google’s platform.Cyanogen and Microsoft announced a partnership on Thursday that will result in Bing search, Skype, OneDrive, OneNote, Outlook, and Microsoft Office becoming part of the Cyanogen OS, which uses a heavily modified version of the Android interface.Exactly what this will look like remains to be seen, but Microsoft said it will create “native integrations” with Cyanogen’s operating system. That hints at integration that goes beyond pre-installed apps and well-placed icons.To read this article in full or to leave a comment, please click here

New malware program Punkey targets point-of-sale systems

Point-of-Sale (PoS) terminals have become an attractive target for hackers over the past year, reflected in the increasing number of RAM-scraping programs that steal payment card information from the memory of such systems.Last month security researchers from Cisco Systems issued a warning about a new PoS threat dubbed PoSeidon and on Wednesday security blogger Brian Krebs reported that the program has already infected PoS terminals at restaurants, bars and hotels in the U.S.To read this article in full or to leave a comment, please click here

Go-to storage and disaster recovery products

LEAF Commercial Capital used to wrestle with tape backups for disaster recovery. Now the equipment leasing and finance company is using a software-based service from Evolve IP for disaster recovery.Rusty Lorenzon, director of IT Infrastructure at Philadelphia-based LEAF, says Evolve IP’s disaster-recovery-as-a-service (DRaaS) has allowed the company to reduce its recovery-time objectives from 48 hours or more to four hours or less. At the same time, LEAF has reduced its disaster recovery operational expenses.“We adopted Evolve IP as an update to our traditional disaster recovery strategy, which had our team using tape backups and interfacing with various DR suppliers,” Lorenzon says. “Evolve IP DRaaS ZT is a flexible solution with an intuitive interface that is easy to configure and use. It’s built for the VMWare hypervisor and is completely SAN agnostic, which allows us to avoid SAN vendor lock-in.”To read this article in full or to leave a comment, please click here

Tech pros’ favorite tools increase IT efficiency

Content is core to the work of Densho, an organization whose mission is to preserve the testimonies of Japanese Americans who were held in internment camps during World War II.In the past, Densho needed a complex storage environment to house its 30TB of production data, says Geoff Froh, deputy director and CIO at the nonprofit organization based in Seattle.“The two-tier infrastructure was composed of high-performance SAN hardware and high-capacity consumer-grade NAS appliances. The SAN was expensive, difficult to manage and not scalable. The NAS gear was unreliable and lacked the IOPS to handle our workload,” Froh recalls.To read this article in full or to leave a comment, please click here

VCDX-NV Interview: Ron Flax On The Importance Of Network Virtualization

Ron Flax is the Vice President of August Schell, a reseller of VMware products and IT services company that specializes in delivering services to commercial accounts and the federal government, particularly intelligence and U.S. Department of Defense. Ron is a VCDX-NV certified network virtualization professional and a VMware vExpert. We spoke with Ron about network virtualization and the NSX career path.

***

The most exciting thing about network virtualization, I think, is the transformative nature of this technology. Networks have been built the same way for the last 20 to 25 years. Nothing has really changed. A lot of new features have been built, a lot of different technologies have come around networks, but the fundamental nature of how networks are built has not changed. But VMware NSX, because it’s a software-based product, has completely altered everything. It enables a much more agile approach to networks: the ability to automate the stand-up and tear-down of networks; the ability to produce firewalling literally at the virtual network interface. And because things are done at software speed, you can now make changes to the features and functions of networking products at software speed. You no longer have to deal with Continue reading

The Upload: Your tech news briefing for Thursday, April 16

In antitrust case, EC could have a tough time proving Google abuseA European Commission victory in its antitrust case against Google is not a sure bet. The narrowly defined case, focusing on search results that allegedly favor Google Shopping, indicates that the Commission thought that broad charges would not stick, legal experts say. And to successfully conclude the case, the Commission must show that Google’s actions harm not just competitors, but consumers as well, which could be a stretch.Israeli camera tech may be lens on future Apple productsTo read this article in full or to leave a comment, please click here

How Do I Get Started with SDN and Virtualization?

Here’s a short question I got from one of my readers:

I am a CCIE in SP/DC & working as Technical Architect in US. I follow your website but I don’t know where to start for SDN/Virtualization/Openstack…

I guess he’s not alone, so here’s a long list of resources I put together in the last 5+ years.

Before I get started: you’ll find links to most of these resources on ipSpace.net SDN Resources page.

YouTube flaw allowed copying comments from one video to another

An Egypt-based security researcher said Google has fixed an interesting vulnerability he and a colleague found in YouTube.Ahmed Aboul-Ela wrote on his blog that he and a fellow researcher, Ibrahim Mosaad, wanted to find a problem in a feature on YouTube “that not many bug hunters have tested.”They focused on a setting in YouTube that holds comments for review before they’re published. If that feature is enabled, comments are then listed in a control panel labeled “held for review.”Aboul-Ela wrote he intercepted the http request that is sent to Google when a comment is approved. The request contains two parameters: “comment_id” and “video_id.”To read this article in full or to leave a comment, please click here

Dropbox to pay security researchers for bugs

Dropbox said Wednesday it will pay rewards to independent researchers who find software flaws in its applications, joining a growing list companies who see merit in crowdsourcing parts of their security testing.The popular file storage service previously publicly recognized researchers, but did not pay a reward, also sometimes referred to as a bug bounty.“In addition to hiring world class experts, we believe it’s important to get all the help we can from the security research community, too,” wrote Devdatta Akhawe, a Dropbox security engineer.Facebook, Google, Yahoo and many other large companies pay researchers rewards that are often determined by the seriousness of the software flaw. Running such programs are more efficient than hiring more security engineers since a company’s applications are analyzed by a larger number of people with diverse security skills.To read this article in full or to leave a comment, please click here

AirDroid app fixes severe authentication vulnerability

AirDroid, a popular management tool for Android devices, has fixed a severe authentication software flaw in its Web interface that could give a hacker complete control over a mobile phone.The problem was fixed in an update released last month, wrote Matt Bryant, a consultant with the security company Bishop Fox, who discovered the flaw. Versions 3.0.4 and earlier of the tool are affected.AirDroid lets people manage their phone from a Windows or Mac tablet or through a Web interface. To do that, it asks for a lot of permissions, such as the ability to send text messages, turn on a camera and have access to the phone, among many others.To read this article in full or to leave a comment, please click here

Dynamic Kubernetes installation/configuration with SaltStack

I’ve been playing more with SaltStack recently and I realized that my first attempt at using Salt to provision my cluster was a little shortsighted. The problem was, it only worked for my exact lab configuration. After playing with Salt some more, I realized that the Salt configuration could be MUCH more dynamic than what I had initially deployed. That being said, I developed a set of Salt states that I believe can be consumed by anyone wanting to deploy a Kubernetes lab on bare metal. To do this, I used a few more of the features that SaltStack has to offer. Namely, pillars and the built-in Jinja templating language.

My goal was to let anyone with some Salt experience be able to quickly deploy a fully working Kubernetes cluster. That being said, the Salt configuration can be tuned to your specific environment. Have 3 servers you want to try Kubernetes on? Have 10? All you need to do is have some servers that meet the following prerequisites and tune the Salt config to your environment.

Environment Prerequisites
-You need at least 2 servers, one for the master and one for Continue reading
