Worth Reading: Oblivious DNS

The recent news that Mozilla and Cloudflare are deploying their own DNS recursive resolver has once again raised hopes that users will enjoy improved privacy, since they can send DNS traffic encrypted to Cloudflare, rather than to their ISP. In this post, we explain why this approach only moves your private data from the ISP to (yet another) third party. —Nick Feamster @CircleID

The Modern Telco is Open, Part 2 Q&A – Virtual Central Office (VCO) in an Open Telco World

Thanks to all who joined us for The Modern Telco is Open, Part 2 – Virtual Central Office (VCO) in an Open Telco World. After the webinar, we took questions from the audience but unfortunately ran out of time before we could get to all their questions. Below is the full The Modern Telco is Open, Part 2 Q&A. 

Integrating the configuration build – Next steps

Hi,

The last post link below, I got introduced to a CI System and basics of it.

https://r2079.wordpress.com/2018/04/03/using-travis-ci-continuous-
integration-with-github/

This post goes further in actually using the CI system.

All the code is hosted here

https://github.com/yukthr/auts.git

-> Requirement is very simple

This is a very basic program which introduces anyone to Jinja2 and
 yaml syntaxing 


Problem  - Have two interfaces ge-0/0/0 and ge-0/0/1, we have to use 
Yaml / Jinja2 and Pyez to develop the configurational 
syntax for this and later on a CI system need to validate the build. 

The code hosted in Github above.
intf.yml    - will have all the interfaces 
template.j2 - will have the appropriate Jinja2 
template.py - will have the python program combining these two

So, we write the code 





Finally build the CI file, but here we also buld the dependencies 
because when CI starts to validate it needs to have all the 
appropriate software installed. It amuses me to the point, 
it spins up the VM and then install the dependencies and then

it validates our code. I have come a long way from manual 
verificaitons / lab testing / CI testing now

IDG Contributor Network: What Larry, Moe and Curly can teach us about network security and SD-WAN agility

In comedy, unexpected actions make for good fun. The pratfalls. The eye pokes. But in networking, the unexpected is hardly funny. And yet it was the antics of the Three Stooges that came to mind as I reviewed the results of Cato Networks’ latest networking survey.The survey canvassed more than 700 enterprise IT buyers from around the globe about the drivers and challenges facing their networking and security deployments. What we observed serves as a promise and warning for anyone considering SD-WAN.SD-WAN is supposed to be the answer to network complexity. And like any good slapstick setup, we can almost see how SD-WAN meets that objective. As an overlay aggregating traffic from MPLS, broadband and any other underlying data transport, SD-WAN hides the complexity of a building a network from multiple data transports. Policies provide the intelligence for SD-WAN to select the optimum network for each application freeing IT from making those calculations and changes manually, if that was even possible.To read this article in full, please click here

New Approaches to Optimizing Workflow Automation

Workflow automation has been born of necessity and has evolved an increasingly sophisticated set of tools to manage the growing complexity of the automation itself.

The same theme keeps emerging across the broader spectrum of enterprise and research IT. For instance, we spoke recently about the need to profile software and algorithms when billions of events per iteration are generated from modern GPU systems. This is a similar challenge and fortunately, not all traditional or physical business processes fall into this scale bucket. Many are much less data intensive, but can have a such a critical impact in “time to …

Reclaiming 1.1.1.1 For The Internet

Hopefully by now you’ve seen the announcement that CloudFlare has opened a new DNS service at the address of 1.1.1.1. We covered a bit of it on this week’s episode of the Gestalt IT Rundown. Next to Gmail, it’s probably the best April Fool’s announcement I’ve seen. However, it would seem that the Internet isn’t quite ready for a DNS resolver service that’s easy to remember. And that’s thanks in part to the accumulation of bad address hygiene.

Not So Random Numbers

The address range of 1/8 is owned by APNIC. They’ve had it for many years now but have never announced it publicly. Nor have they ever made any assignments of addresses in that space to clients or customers. In a world where IPv4 space is at a premium, why would a RIR choose to lose 16 million addresses?

As it turns out, 1/8 is a pretty bad address space for two reasons. 1.1.1.1 and 1.2.3.4. These two addresses are responsible for most of the inadvertent announcements in the entire 1/8 space. 1.2.3.4 is easy to figure out. It’s the most common example IP address Continue reading

IDG Contributor Network: The serverless cloud provider was last year – what can we expect to change?

Reno-based analyst Synergy Research Group released a review of the 2017 cloud market on January 4th. The report, which estimated the total scope of the industry at $180 billion, gauged the year-over-year growth rate of infrastructure as a service (cloud hosting) and platform as a service (combined cloud hardware and software) at 47%. Such astronomical growth in the infrastructure of cloud is fueling growth of data centers. The extent to which cloud is becoming the new form of infrastructure cannot be overstated, with Cisco predicting 95% of data center traffic will be through cloud infrastructure by 2021.To read this article in full, please click here

Argo Tunnel: A Private Link to the Public Internet

Photo from Wikimedia Commons

Today we’re introducing Argo Tunnel, a private connection between your web server and Cloudflare. Tunnel makes it so that only traffic that routes through Cloudflare can reach your server.

You can think of Argo Tunnel as a virtual P.O. box. It lets someone send you packets without knowing your real address. In other words, it’s a private link. Only Cloudflare can see the server and communicate with it, and for the rest of the internet, it’s unroutable, as if the server is not even there.

How this used to be done

This type of private deployment used to be accomplished with GRE tunnels. But GRE tunnels are expensive and slow, they don’t really make sense in a 2018 internet.

GRE is a tunneling protocol for sending data between two servers by simulating a physical link. Configuring a GRE tunnel requires coordination between network administrators from both sides of the connection. It is an expensive service that is usually only available for large corporations with dedicated budgets. The GRE protocol encapsulates packets inside other packets, which means that you will have to either lower the MTU of your origin servers, or have your router do Continue reading

How the Lenca are Restoring the Past to Build their Future

The Internet has the potential to enable Indigenous communities to continue living on remote traditional lands without diminishing their access to services and information. The potential can go a long way towards closing the digital divide and offers new opportunities while preserving Indigenous culture.

In the ongoing debate about what difference the digital makes to the concept of Indigeneity itself, the voices of Indigenous people are what has been missing. It should be left up to community members to be caught up in this age of information and build the future on their own terms.

This is the story of Lenca people of Azacualpa, an Indigenous community of Yamaranguila in Intibucá, Honduras. In June 2017 they decided to start their relationship with technology by creating Radio Azacualpa, a radio station run by women, with the support of Cultural Survival’s Community Media Grants Project. It was a dream come true.

The radio tagline “La voz de las Mujeres” – the voice of women –  says it all. “One of our goals as a radio station is to achieve recognition of our rights as women and to achieve equality,” explains Maria Santos, leader of the Azacualpa community.

In 2018, the Lenca decided Continue reading
