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.

collector { ip=10.0.0.70 }
docker { }
pcap { dev=docker0 }

}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
If you have seen our other post you know that we released WARP to the last members of our waiting list today. With WARP our goal was to secure and improve the connection between your mobile devices and the Internet. Along the way we ran into problems with phone and operating system versions, diverse networks, and our own infrastructure, all while working to meet the pent up demand of a waiting list nearly two million people long.
To understand all these problems and how we solved them we first need to give you some background on how the Cloudflare network works:
The Cloudflare network is composed of data centers located in 194 cities and in more than 90 countries. Every Cloudflare data center is composed of many servers that receive a continual flood of requests and has to distribute those requests between the servers that handle them. We use a set of routers to perform that operation:
Our routers listen on Anycast IP addresses which are advertised over the public Internet. If you have a site on Cloudflare, your site is available via two of these addresses. In this case, I am doing a DNS query 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
In a previous tutorial we have built DPDK 18.11.2 and Open vSwitch 2.11.1 on Linux Debian 10.1 VM (buster). We have created a L3 Open vSwitch QEMU appliance that we will use to compare performance of Open vSwitch with enabled/disabled DPDK. A network topology is depicted on the Picture 1.
The lab is created as GNS3 project which consists of a single Debian Open vSwitch appliance. Two Linux Core 6.3 hosts PC1 and PC2 are connected to the switchports Ethernet0 and Ethernet1, respectively. Firstly, we are going to bind the both ports to DPDK-compatible driver and create a bridge with the DPDK ports attached to the bridge. As a last step, we will measure maximum achievable bandwidth with iPerf3 tool. The host PC1 will be be acting as a iPerf3 client connecting to the iPerf3 server running on the host PC2.
Note: Open vSwitch 2.11.1 appliance built on Debian 10 buster and DPDK 18.11.2 is available in Download-> Appliance Section. The Linux Core 6.3 image is available there, as well.

Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag).
DPDK is the Data Plane Development Kit that consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures.
Note: Open vSwitch images are customized with my after install script and they are ready for use in GNS3.
Username is debian with the password debian.

A while ago Ruben Tripiana tried to configure BGP on Cisco IOS using IETF YANG data models… and failed. In Spring 2019 Building Network Automation Solutions online course Chris Crook decided to deploy BGP routing on multiple platforms using YANG data models instead of configuration templates. Not only did he succeed, he also documented his work and the tools he used, and published the solution so you can replicate his efforts.

50 ways to leak your data: an exploration of apps’ circumvention of the Android permissions system Reardon et al., USENIX Security Symposium 2019
The problem is all inside your app, she said to me / The answer is easy if you take it logically / I’d like to help data in its struggle to be free / There must be fifty ways to leak their data.
You just slip it out the back, Jack / Make a new plan, Stan / You don’t need to be coy, Roy / Just get the data free.
Hop it on the bus, Gus / You don’t need to discuss much / Just drop off the key, Lee / And get the data free…
— Lyrics adapted from “50 ways to leave your lover” by Paul Simon (fabulous song btw., you should definitely check it out if you don’t already know it!).
This paper is a study of Android apps in the wild that leak permission protected data (identifiers which can be used for tracking, and location information), where those apps should not have been able to see such data due to a lack of granted permissions. By detecting Continue reading
