We’re watching you: The U.S. CIA secretly had an ownership stake in Swiss encryption company Crypto AG for decades and was able to read encrypted messages sent using the company’s technology, the Washington Post reports. West German intelligence agencies worked with the CIA. Forbes columnist Jody Westby called for a congressional investigation.
We’re watching you, part two: Meanwhile, Russia’s Federal Security Service has ordered some large Internet companies in the country to give it continuous access to their systems, the New York Times reports. The FSB has targeted more than 200 companies, including popular messenger service Telegram, social network VK. and classified advertisement website Avito.ru.
Big bucks for space-based Internet: Astranis, a satellite Internet startup focused on bringing service to underserved areas, has raised $90 million in new funding, Fortune says. The new funding will help Astranis deploy its first satellite, focused on providing Internet service in Alaska.
Not so fast: Satellites, however, have some downsides, according to a story on TheConversation.com. Satellites are vulnerable to cyberattacks, with hackers potentially able to shut them down or even turn them into weapons, the story suggests.

What’s the next logical automation step after you cleaned up device configurations and started using configuration templates? It obviously depends on your pain points; for Anne Baretta it was a network inventory database stored in SQL tables (and thus readily accessible from his other projects).

Migrating a privacy-safe information extraction system to a software 2.0 design, Sheng, CIDR’20
This is a comparatively short (7 pages) but very interesting paper detailing the migration of a software system to a ‘Software 2.0’ design. Software 2.0, in case you missed it, is a term coined by Andrej Karpathy to describe software in which key components are implemented by neural networks. Since we’ve recently spent quite a bit of time looking at the situations where interpretable models and simple rules are highly desirable, this case study makes a nice counterpoint: it describes a system that started out with hand-written rules, which then over time grew complex and hard to maintain until meaningful progress had pretty much slowed to a halt. (A set of rules that complex wouldn’t have been great from the perspective of interpretability either). Replacing these rules with a machine learned component dramatically simplified the code base (45 Kloc deleted) and set the system back onto a growth and improvement trajectory.
A really interesting thing happens when you go from developing a Software 1.0 (i.e., traditional software) to a Software 2.0 system. In Software 1.0 we spend Continue reading
Hello my friend,
We are slowly but surely start talking about more and more useful and interesting topics staying yet at a basic level. Today you will learn about variables in Python, as variables are obviously the basic building block of any tool.
Don’t wait to be kicked out of IT business. Join our network automation training to secure your job in future. Come to NetDevOps side.
How does the training differ from this blog post series? Here you get the basics and learn some programming concepts in general, whereas in the training you get comprehensive set of knowledge with the detailed examples how to use Python for the network and IT automation. You need both.
We will learn how to create and use in Python 3.8 several types of the variables such as:
The different types of variables are used for the different purposes, that’s why the more variables’ type you know, the better code you can write. We must admit that this list of the variables isn’t complete. That is why in the next couple of blogposts you will see Continue reading
MikroTik announced VxLAN support on Valentine’s Day (Feb 14th) of 2020.
This is a significant feature addition for RouterOSv7 as it will pave the way for a number of other additions like EVPN in BGP.
It will also give MikroTik the ability to appeal to enterprises and data centers that might need cost-effective VxLAN capable devices.
Service Providers are also moving towards VxLAN as a future replacement for VPLS so this is helpful for that market as well.
Download the OVA here:
https://download.mikrotik.com/routeros/7.0beta5/chr-7.0beta5.ova
The initial release of VxLAN is based on unicast and multicast to deliver Layer 2 frames.
As there is no EVPN support, the VTEPs must be manually configured for each endpoint in a full mesh configuration.
The VxLAN interface can then be bridged to a physical ethernet port or VLAN interface to deliver the traffic to the end host.
Here is an overview lab in EVE-NG with a basic setup using 3 linux servers on the same 10.1.1.0/24 subnet which is carried as an overlay by VxLAN.
VxLAN reachability for VTEPs is acheived with OSPFv2 and loopback addresses.

Dinesh Dutt, a pragmatic IP routing guru, the mastermind behind great concepts like simplified BGP configuration, and one of the best ipSpace.net authors, finally decided to start blogging. His first article: describing the impact of having 256 100GE ports in a single ASIC (Tomahawk 4). Hope you’ll enjoy his musings as much as I did ;)

When talking about high-end HPC systems in the world, much of the attention often is paid to the massive supercomputers that are being developed by the likes of system makers Cray (now part of Hewlett Packard Enterprise and the main contractor on two exascale systems), Fujitsu, Atos, IBM, and others along with component makers Intel (which is a primary contractor on one exascale system), AMD, and Nvidia. …
