TL-DR: Dropbox is harassing me about new products. Combined with poor performance of their bloated app and enormous waisting of my disk space, I’m getting close to quitting. I want to use Dropbox to synchronise files between my various devices aka desktop, laptop, tablet and smartphone for quite some time. I like it enough to […]

The autumn 2019 webinar season is in full swing ;) We’re almost done with Azure Networking webinar (the last session will take place on October 10th) and the network automation course is nicely chugging along – a few weeks ago Matthias Luft talked about supply-chain security in open-source software and today we’ll enjoy the start with a single source of truth presentation by Damien Garros.
Dinesh Dutt is coming back on October 8th with another installment of EVPN saga, this time focused on running EVPN on Linux hosts, and on October 22nd Donald Sharp will tell us all about the underlying magic box – the Free Range Routing software.
But there are even more open-source goodies waiting for you: on October 15th we’ll have Pete Lumbis describing the new features Cumulus Linux got in the last year, including AutoBGP and AutoMLAG.
Most everything I mentioned above apart is accessible with Standard ipSpace.net Subscription, and you’ll need Expert Subscription to enjoy the automation course contents.
China's Baidu donated the Baetyl seed code, while Dianomic contributed Fledge.
This is the second of the two part EVPN-PIM blog series exploring the feature and network deployment choices. If you missed part one, learn about BUM optimization using PIM-SM here.
Servers in a data-center Clos are typically dual connected to a pair of Top-of-Rack switches for redundancy purposes. These TOR switches are setup as a MLAG (Multichassis Link Aggregation) pair i.e. the server sees them as a single switch with two or more bonded links. Really there are two distinct switches with an ISL/peerlink between them syncing databases and pretending to be one.
The MLAG switches (L11, L12 in the sample setup) use a single VTEP IP address i.e. appear as an anycast-VTEP or virtual-VTEP.
Additional procedures involved in EVPN-PIM with anycast VTEPs are discussed in this blog.
Friend: “So you are working on PIM-MLAG?”
Me: “No, I am implementing EVPN-PIM in a MLAG setup”
Friend: “Yup, same difference”
Me: “No, it is not!”
Friend: “OK, OK, so you are implementing PIM-EVPN with MLAG?”
Me: “Yes!”
Friend: “i.e. PIM-MLAG?”
Me: “Well, now that you put it like that….……..NO, I AM NOT!! Continue reading

On today's Network Neighborhood we talk with Dana Iskoldski, Corporate Communications Manager at BlueCat Networks. We discuss the role of corporate comms in tech, how the position straddles marketing and community engagement, and how Dana grapples with the natural skepticism of engineers.

sflow {The above /etc/hsflowd.conf file, see Configuring Host sFlow for Linux via /etc/hsflowd.conf, enables the docker {} and pcap {} modules for detailed visibility into container metrics and network traffic flows, and streams telemetry to an sFlow collector (10.0.0.70). The configuration is the same for every node making it simple to install and configure Host sFlow on all nodes using orchestration software such as Puppet, Chef, Ansible, etc.

When 16-year-old Swedish environmental activist Greta Thunberg burst onto the global scene a few months ago, people underestimated the power this young girl would have to raise awareness and rally the world around climate change. Today, she has become a fearless advocate, boldly speaking out and holding politicians to account for their lack of action on the climate crisis. We need more Gretas.
And they’re out there.
We’re proud to introduce 30 young changemakers who make up the 2019 cohort of the Internet Society’s IGF Youth Ambassadors Program. The group is made up of 15 women and 15 men from 21 countries. This cadre of young leaders are working on many of the pressing issues affecting the Internet globally.
In November, they’ll bring their drive for change to Berlin, Germany, to take part in the Internet Governance Forum (IGF). This is an annual multistakeholder forum for inclusive policy dialogue on shared principles, procedures, and programs that shape the evolution and use of the Internet. Although not an official decision-making body, the IGF remains an important forum. Many of the world’s experts in and advocates for the Internet gather there for discussion, networking, research sharing, and best practices from around the Continue reading
Today, after a longer than expected wait, we're opening WARP and WARP Plus to the general public. If you haven’t heard about it yet, WARP is a mobile app designed for everyone which uses our global network to secure all of your phone’s Internet traffic.
We announced WARP on April 1 of this year and expected to roll it out over the next few months at a fairly steady clip and get it released to everyone who wanted to use it by July. That didn’t happen. It turned out that building a next generation service to secure consumer mobile connections without slowing them down or burning battery was… harder than we originally thought.
Before today, there were approximately two million people on the waitlist to try WARP. That demand blew us away. It also embarrassed us. The common refrain is consumers don’t care about their security and privacy, but the attention WARP got proved to us how wrong that assumption actually is.
This post is an explanation of why releasing WARP took so long, what we've learned along the way, and an apology for those who have been eagerly waiting. It also talks briefly about the rationale for why we Continue reading
