Last Month in Internet Intelligence: July 2018

In June, we launched the Internet Intelligence microsite, including the new Internet Intelligence Map. In July, we published the inaugural “Last Month in Internet Intelligence” overview, covering Internet disruptions observed during the prior month. The first summary included insights into exam-related outages and problems caused by fiber cuts. In this month’s summary, covering July, we saw power outages and fiber cuts, as well as exam-related and government-directed shutdowns, disrupt Internet connectivity. In addition, we observed Internet disruptions in several countries where we were unable to ascertain a definitive cause.

Power Outages

It is no surprise that power outages can wreak havoc on Internet connectivity – not every data center or router is connected to backup power, and last mile access often becomes impossible as well.

At approximately 20:00 GMT on July 2, the Internet Intelligence Map Country Statistics view showed a decline in the traceroute completion ratio and DNS query rate for Azerbaijan, related to a widespread blackout. These metrics gradually recovered over the next day. Published reports (Reuters, Washington Post) noted that the blackout was due to an explosion at a hydropower station, following an overload of the electrical system due to increased use Continue reading

New my.ipspace.net Design

During the last weeks I migrated the whole my.ipspace.net site (apart from the workgroup administration pages) to the new ipSpace.net design. Most of the changes should be transparent (apart from the pages looking better than before ;); I also made a few more significant changes:

Here we go again!

It’s time to start a new term on #themorningpaper. I read my very first #themorningpaper on the 30th July 2014 (“Why functional programming matters”, Hughes 1990) and since then, bar three scheduled breaks a year, I’ve been reading a research paper every weekday. Since the 8th October 2014, I’ve also been posting a write-up of the day’s paper on The Morning Paper blog. There’s not always an exact 1:1 correspondence between a post and a paper, but it’s pretty good. On that basis, you can now find somewhere in the order of 840 paper write-ups on the blog, and we’re racing towards the 1,000 mark!

People often ask, and yes, it’s a lot of work to curate papers, read them, and post the write-ups! Somewhere on the order of 15-20 hours a week (and all outside of my regular work commitments). I’ve got a tremendous amount of value out of this habit and I intend to keep it going. However, starting again this term it suddenly felt like a big load to carry – might be something to do with the fact that we’re moving house in a couple of weeks! So to keep things feeling fun for me and Continue reading

Integration of GNS3 with VMWare Workstation

Integration Of GNS3 with VM

There has been multiple query regarding the integration of GNS3 with VMWare  , the  goal of this Post is to help to get the users know the easy steps to integrate GNS3 with VM  .  This will not only help the user to practice  CCNA,CCNP  lab in GNS  but also work with  with network automation scenarios.

Lets start with downloading the  GNS3 and corresponding GNS3 VM from GNS site.

Now you need to install VMWare Player ,  download the Vmware workstation Player 12 which i found to be compatible with GNS3 .The last item to download is VIX API , so in total we have downloaded 4 items as mentioned below with required links:

1)GNS3  èhttps://www.gns3.com/software 

2) GNS3 VM(.ovo file)èhttps://www.gns3.com/software 

3)Vmware workstation Player èhttps://filehippo.com/download_vmware-workstation-pro/68880/

4) VIX APi èhttps://www.vmware.com/support/developer/vix-api/

Once VM Player is downloaded , need to open the GNS3 VM .ovo  file and import it.

You can see GNS3 VM  on Workstation player page as below

If You want to tweek the VM Memory, cpu that can too be done .   

You can see the  IP address obtained Continue reading

BGP/DNS Hijacks Target Payment Systems

In April 2018, we detailed a brazen BGP hijack of Amazon’s authoritative DNS service in order to redirect users of a crypto currency wallet service to a fraudulent website ready to steal their money.

In the past month, we have observed additional BGP hijacks of authoritative DNS servers with a technique similar to what was used in April. This time the targets included US payment processing companies.

As in the Amazon case, these more recent BGP hijacks enabled imposter DNS servers to return forged DNS responses, misdirecting unsuspecting users to malicious sites.  By using long TTL values in the forged responses, recursive DNS servers held these bogus DNS entries in their caches long after the BGP hijack had disappeared — maximizing the duration of the attack.

The Hijacks

At 23:37:18 UTC on 6 July 2018, Digital Wireless Indonesia (AS38146) announced the following prefixes for about thirty minutes.  These prefixes didn’t propagate very far and were only seen by a handful of our peers.

Show 401: A Deeper Understanding Of Free Range Routing (FRR)

Free Range Routing (FRR) is an open source routing project. It’s designed to provide a full routing stack that can run on top of a network OS. FRR is itself a fork from the Quagga routing project.

On today’s Weekly Show, recorded live from IETF 102, we talk with Donald Sharp to learn about FRR, understand its capabilities, and get an update on roadmap features.

We also get a behind-the-scenes look at how new features are chosen, architectural issues that can lead to performance bottlenecks (and how to overcome them), and the challenge of making a programmatic interface for a project that was not originally conceived with that in mind.

We also discuss open source communities–how to understand them, the sorts of people that are involved with them, and the role a developer plays vs. a product consumer.

Then we get specific as to how someone with no previous project involvement can vet the community, decide to become involved, and add value to the group at large–even if they aren t developers.

Donald Sharp is Principal Engineer at Cumulus Networks and a lead contributor to the FRR project.

I enjoyed some of the sessions and also had fun talking to attendees. The topic I presented was “Deep dive into Kubernetes Networking”. Other than covering Kubernetes networking basics, I also touched … Continue reading Container Conference Presentation →

Arm flexes flexibility with Pelion IoT announcement

The pervasiveness of Arm-based silicon – it’s everywhere from cars to signage to smartphones to supercomputers – makes the company a natural fit for an internet of things platform like the one it just announced.The Pelion IoT Platform's main selling point is its universality – the company boasts that it’s able to handle “any device, any data, any cloud” – in a marketplace overflowing with vertical-specific solutions. (GE and Siemens make industrial IoT products, other companies make platforms designed specifically to work well in healthcare, fleet management, or agricultural environments, and so on.)[ Check out our corporate guide to addressing IoT security. ] Pelion can sit on an edge device, in a data center, or even in an endpoint, integrating devices into a working ecosystem, although the focus is on the edge.To read this article in full, please click here

Stuff The Internet Says On Scalability For August 3rd, 2018

Hey, it's HighScalability time:

 

Everything starts with Doug Engelbart — Jane Metcalfe.
It was the very first time (1968) the world had ever seen a mouse, seen outline processing, seen hypertext, seen mixed text and graphics, seen real-time video conferencing. — Doug Engelbart (Valley of Genius).
ARPA funded the demo at a cost of $1 million. Most importantly? It was the first use of a todo list as an example. A tradition unlike any other.

 

Do you like this sort of Stuff? Please lend me your support on Patreon. It would mean a great deal to me. And if you know anyone looking for a simple book that uses lots of pictures and lots of examples to explain the cloud, then please recommend my new book: Explain the Cloud Like I'm 10. They'll love you even more.
