Muhammad Shabbbir Awan: Reflections on the WTDC17

It’s been 5 months since WTDC17 concluded and I had time to reflect on the outcomes of the conference and the experience itself. WTDC sets the ITU’s development agenda and in Argentina last October over 1000 government delegates from close to 135 countries gathered during the two-week period. They were there to discuss a range of issues and shape the development sector’s priorities for the next four years. For me, it was a trip of many firsts: my first experience as an observer participating in a multilateral conference; my first trip to South America; and, as a visually impaired person, the eighteen hours flight duration was my first such experience.

To recall, I was a member of the Internet Society delegation as a Fellow. For me, the two motivators to apply for the fellowship opportunity were: first, the theme for WTDC17 (“ICTs for Sustainable Development Goals”) and possibility to make a difference. Second, my quest to learn even more about Internet Governance processes and to participate in the discussions.

WTDC17 had a packed agenda that included ceremonial events marking the 25th Anniversary of the Development Sector and side events on a range of Sustainable Development Goal (SDG) topics.

sFlow available on Juniper MX series routers

sFlow support on MX Series devices—Starting in Junos OS Release 18.1R1, you can configure sFlow technology (as a sFlow agent) on a MX Series device, to continuously monitor traffic at wire speed on all interfaces simultaneously. The sFlow technology is a monitoring technology for high-speed switched or routed networks.  - New and Changed Features

Understanding How to Use sFlow Technology for Network Monitoring on a MX Series Router lists the following benefits of sFlow Technology on a MX Series Router:
  • sFlow can be used by software tools like a network analyzer to continuously monitor tens of thousands of switch or router ports simultaneously.
  • Since sFlow uses network sampling (forwarding one packet from ‘n’ number of total packets) for analysis, it is not resource intensive (for example processing, memory and more). The sampling is done at the hardware application-specific integrated circuits (ASICs) and hence it is simple and more accurate.
With the addition of the MX series routers, Juniper now supports sFlow across its entire product range:
Universal support for Continue reading

Introducing “Cooking with Cumulus” – Episode one

Alright, we know you’re hungry for more Cumulus goodness, so we’ve cooked up something new that we think will satiate your appetite for awesome technical content. It’s the perfect mix of one part technical deep-dive, one part fun and just a pinch of silliness. The wait is over — our latest project is hot, fresh and ready to serve!

Okay, enough teasing. Today we’re introducing the new Cumulus Networks video series “Cooking with Cumulus!”

“Wait, what does cooking have to do with networking??” you may think to yourself. Glad you asked. You may already know JR Rivers as the CTO and co-founder of Cumulus Networks, but did you know he’s also a master of the culinary arts? Here at the Mountain View office, we know it’s the start of a good day when JR brings in his homemade food to share. From chocolate chip cookies to paella, we’ve approved (and enjoyed) his many recipes. So, we decided that we wanted to share that gift with the rest of the Cumulus community by combining two of JR’s greatest passions — networking and cooking. The resulting brain child was a video series where we put two networking nerds in a Continue reading

Weekend Reads 040618: Kernel Programming, Secure Messaging, and Icebergs

Programming in user space is safer for a very small number of reasons, not the least of which is the virtual memory system, which tricks programs into believing they have full control over system memory and catches a small number of common C-language programming errors, such as touching a piece of memory that the program has no right to touch. Other reasons include the tried-and-true programming APIs that operating systems have now provided to programs for the past 30 years. All of which means programmers can possibly catch more errors before their code ships, which is great news—old news, but great news. What building code in user space does not do is solve the age-old problems of isolation, composition, and efficiency. —George V. Neville-Neil @ACM

There is no such thing as a perfect or one-size-fits-all messaging app. For users, a messenger that is reasonable for one person could be dangerous for another. And for developers, there is no single correct way to balance security features, usability, and the countless other variables that go into making a high-quality, secure communications tool. @EFF

Breaches of private information in hospital records are serious and expensive security events but remediating them can be deadly. Continue reading

New distributed database adds international and GDPR controls

The European Union’s General Data Protection Regulation (GDPR) will force very strict new privacy compliance rules on firms doing business in the EU, but a startup that has an atrocious company and product name has what it says is the solution to maintaining compliance.Cockroach Labs has introduced version 2.0 of its CockroachDB distributed database, which can be run in a data center or cloud.

New RFC 8360 – RPKI Validation Reconsidered – Offers Alternative Validation Procedures to Improve Routing Security

RFC 8360, Resource Public Key Infrastructure (RPKI) Validation Reconsidered, is now published in the RFC libraries.

What is RPKI?

Resource Public Key Infrastructure (RPKI) aims to improve the security of the Internet routing system, specifically the Border Gateway Protocol (BGP), by establishing a hierarchy of trust for BGP routes. Today, most organizations simply trust that routing updates they get are sent by authorized senders. This is how bad actors and misconfigurations can cause massive routing issues. With RPKI, the receiving organization can verify that the sending organization is authorized to send the routing update.

RPKI works by issuing X.509-based resource certificates to holders of IP addresses and AS numbers to prove assignment of these resources. These certificates are issued to Local Internet Registries (LIRs) by one of the five Regional Internet Registries (RIRs) who allocate and assign these resources in their service regions.

What Does This RFC Do?

In the IETF, participants have been discussing issues that may arise when resources move across registries. The problem happens when a subordinate certificate “over-claims” resources compared to its parent. According to the standard validation procedure specified in RFC 6487, the whole branch beneath would be invalidated. The closer to Continue reading

Cloudflare Argo Tunnel with Rust+Raspberry Pi

Cloudflare Argo Tunnel with Rust+Raspberry Pi

Yesterday Cloudflare launched Argo Tunnel. In the words of the product team:

Argo Tunnel exposes applications running on your local web server, on any network with an Internet connection, without adding DNS records or configuring a firewall or router. It just works.

Once I grokked this, the first thing that came to mind was that I could actually use one of my Raspberry Pi's sitting around to serve a website, without:

  • A flaky DDNS running on my router
  • Exposing my home network to the world
  • A cloud VM

Ooooh... so exciting.

The Rig

I'll assume you already have a Raspberry Pi with Raspbian on it.

Cloudflare Argo Tunnel with Rust+Raspberry Pi

Plug the Pi into your router. It should now have an IP address. Look that up in your router’s admin UI:

OK, that's promising. Let's connect to that IP using the default pi/raspberry credentials:

$ ssh 192.168.8.26 -l pi
