What’s the difference between being an engineer or a metaengineer? In this Network Collective Short Take, Russ White differentiates between the two and explores when it makes sense to be one or the other.
The post Short Take – Metaengineering appeared first on Network Collective.
In case you haven’t heard, there’s a new vector for Distributed Denial of Service (DDoS) attacks out there right now and it’s pretty massive. The first mention I saw this week was from Cloudflare, where they details that they were seeing a huge influx of traffic from UDP port 11211. That’s the port used by memcached, a database caching system.
Surprisingly, or not, there were thousands of companies that had left UDP/11211 open to the entire Internet. And, by design, memcached responds to anyone that queries that port. Also, carefully crafted packets can be amplified to have massive responses. In Cloudflare’s testing they were able to send a 15 byte packet and get a 134KB response. Given that this protocol is UDP and capable of responding to forged packets in such a way as to make life miserable for Cloudflare and, now, Github, which got blasted with the largest DDoS attack on record.
How can you fix this problem in your network? There are many steps you can take, whether you are a system admin or a network admin:
Computing used to be far away.
It was accessed via remote command terminals, through time sliced services. It was a pretty miserable experience. During the personal computing revolution, computing once again became local. It would fit under your desk, or in a small dedicated “computer rooms”. You could touch it. It was once more, a happy and contented time for computer users. The computer was personal again. There was a clue in the name.
However, as complexity grew, and as networks improved, computing was effectively taken away again and placed in cold dark rooms once more far, far away for …

Hyperscale companies like AWS have led the way on automation, but enterprise IT can close the gap by following these steps.
After introducing PowerNSX Anthony Burke illustrated how easy it is to use with a Hello, World equivalent: creating a logical switch (VXLAN segment).
You’ll need at least free ipSpace.net subscription to watch the video.
Want to know more about VMware NSX? We’ll run an NSX-focused event and a NSX Deep Dive workshop in Zurich on April 19th 2018, an overview webinar comparing NSX, ACI and EVPN on March 1st, and a deep dive in VMware NSX architecture later in 2018.
As a consultant within the NSX PSO practice, one of the conversations that comes up with customers often is how NSX enables migration from a legacy datacentre to an NSX managed datacentre. This was the case with a customer recently who were looking to move out of a datacentre that was scheduled to be decommissioned. The problem was that the customer workloads needed to be migrated to a Logical Switch within the new datacentre without changing IP addressing, and with minimal downtime.
There are four approaches available to us with NSX for vSphere that might help solve this problem:
The platform interoperates with the GSMA's Mobile Connect technology.
The general consensus, for as long as anyone can remember, is that there is an insatiable appetite for compute in the datacenter. Were it not for the constraints of budgets, for both the acquisition of iron, the facilities to house it, the electricity to power and cool it, and the people to manage it, it is safe to say that the installed base of servers worldwide would be much larger than it is.
But the world doesn’t work that way, and there are constraints. But thanks to ever more complex applications, ever richer media, and a burning desire to save …
The Server Market Booms, And It Could Last For A While was written by Timothy Prickett Morgan at The Next Platform.
Colegio Técnico National (CTN) of Asunción is one of the top schools in Paraguay offering the technical baccalaureate. It was created by the country’s Ministry of Education and Science in 1980. The school is attended by more than 1,500 students from the capital city and from nearby towns like Luque, Fernando de la Mora, San Lorenzo, Lambaré, and Capiatá.
As with most of Paraguayan state schools, the CTN does not have the right infrastructure for an appropriate development of modern education. The little equipment owned by the CTN, donated more than 25 years ago by private or charitable institutions, are today too obsolete. Classes do not have any type of interactive material due to the lack of an Internet connection, equipped laboratories, and modern computers. A new project lead by the Paraguay Chapter and supported by the Internet Society Beyond the Net Funding Programme will provide the school with Internet access and set up a high-tech electronics lab to ensure a quality environment for the development of innovative solutions based on robotics, automation, e-learning systems, and the Internet of Things. 250 students will be trained in the use of online tools. ReVa , a virtual library, will be available Continue reading
