IDG Contributor Network: Using Passpoint for private Wi-Fi networks

We normally think of Passpoint, the Wi-Fi Alliance certification, as a feature for Wi-Fi hotspots owned and operated by service providers. Passpoint enables comprehensive inter-carrier roaming, with discovery, authentication and accounting.But, as with any good protocol, the possible applications greatly outstrip the scenarios originally considered. Enterprise access points already support Passpoint. And as implementation in phones moves forward, slowly but surely non-carriers are finding interesting new applications.9 tips for speeding up your business Wi-Fi Passpoint’s big innovation is decoupling service advertising from the Service Set Identifier (SSID). An access point can advertise, in addition to its SSID, a number of service providers that provide roaming possibilities. When a device starts authentication, the access point relays to the respective service provider’s authentication server, then provides an internet connection.To read this article in full or to leave a comment, please click here

Survey Paints A Bleak Picture of the Current State of Trust Online

The 2017 CIGI-Ipsos Global Survey on Internet Security and Trust paints a bleak picture of the current state of trust online. A majority of those surveyed said they are more concerned about their privacy than the year before, with an almost even split between those “much more concerned” and those only “somewhat more concerned”. When asked whether they agree with the statement “overall, I trust the Internet”, only 12% of respondents strongly agreed and a further 43% somewhat agreed. This means only a little more than half agreed that they trust the Internet, and some even expressed some reservation by choosing to respond “somewhat agree”.

Comparing Docker deployment options in public cloud

Few weeks back, I did a presentation in Container conference, Bangalore comparing different solutions available to deploy Docker in the public cloud. Slides are available here. I have also put the steps necessary along with short video for each of the options in the github page here. Abstract of the talk: Containers provide portability for … Continue reading Comparing Docker deployment options in public cloud →

Trump claimed on Earth Day: ‘Rigorous science is critical to my administration’

If you had been living under a rock, then you might actually believe that President Trump plans to protect the environment and support science.Trump’s Earth Day statement began: Our Nation is blessed with abundant natural resources and awe-inspiring beauty. Americans are rightly grateful for these God-given gifts and have an obligation to safeguard them for future generations. My Administration is committed to keeping our air and water clean, to preserving our forests, lakes, and open spaces, and to protecting endangered species.To read this article in full or to leave a comment, please click here

Optimizing OpenVPN Throughput

In the previous post, I talked about OpenVPN TCP and UDP tunnels and why you should not be using TCP. In this post, I’m going to talk about optimizing the said tunnels to get the most out of them.

Believe it or not, the default OpenVPN configuration is likely not optimized for your link. It probably works but its throughput could possibly be improved if you take the time to optimize it.

A tunnel has 2 ends! Optimizing one end, does not necessarily optimizes the other. For the proper optimization of the link, both ends of the tunnel should be in your control. That means when you are using OpenVPN in server mode serving different clients that you do not have control over, the best you could do is to optimize your own end of the tunnel and use appropriate default settings suitable for the most clients.

Below are some techniques that could be used to optimize your OpenVPN tunnels.

Compression

In today’s world where most connections are either encrypted or pre-compressed (and more commonly both), you probably should think twice before setting up compression on top of your vpn tunnel.

While it still could be an effective way Continue reading

Sharing state between host and upstream network: LACP part 3

So far in the previous articles, we’ve covered the initial objections to LACP a deep dive on the effect on traffic patterns in an MLAG environment without LACP/Static-LAG. In this article we’ll explore how LACP differs from all other available teaming techniques and then also show how it could’ve solved a problem in this particular deployment.

I originally set out to write this as a single article, but to explain the nuances it quickly spiraled beyond that. So I decided to split it up into a few parts.
• Part1: Design choices – Which NIC teaming mode to select

• Part2: How MLAG interacts with the host
• Part3: “Ships in the night” – Sharing state between host and upstream network

Ships in the night

An important element to consider is LACP is the only uplink protocol supported by VMware that directly exchanges any network state information between the host and its upstream switches. An ESXi host is also sortof a host, but also sortof a network switch (in so far as it does forward packets locally and makes path decisions for north/south traffic); here in lies the problem, we effectively have network devices forwarding packets between each other, but Continue reading

There’s now a tool to test for NSA spyware

Has your computer been infected with a suspected NSA spying implant? A security researcher has come up with a free tool that can tell.Luke Jennings of security firm Countercept wrote a script in response to last week’s high-profile leak of cyberweapons that some researchers believe are from the U.S. National Security Agency. It's designed to detect an implant called Doublepulsar, which is delivered by many of the Windows-based exploits found in the leak and can be used to load other malware.To read this article in full or to leave a comment, please click here

Self Driving Cars and Network Automation

Last year at Interop, there was a great mini-conference dedicated to the DevOps for Networking community. In that session, I kicked off the day with a general view of where the industry was with respect to the intersection of DevOps and networking with a focus on network automation.

One of the analogies I made was comparing network automation to self-driving cars posing the question, “Are they real?”…“Are they real for us (the consumer)?”

Self-Driving Cars

No, they are not, but I continued to make the analogy. Is complete network automation real today? While, the answer is yes, it’s not really a reality for most…yet.

So, what’s the connection between self-driving cars and network automation?

Start small and expand. Pick a problem, solve it, and integrate it.

Self-Driving Cars are Coming

While self-driving cars aren’t a reality for us to buy and purchase today, intelligent cars are– these are cars that have high-value services and features enhancing the way we drive, our safety, and much more generally, the way we in which we consume the streets and infrastructure around us.

Intelligent Cars

These include automated features like self-parking, back-up cameras, automated beeping as you back-up, automatic-brakes, GPS, and computer systems that give Continue reading
