Internet of Things Messaging, Part 3: Testing Mosquitto

So, in the last installment of this series on the messaging protocol MQTT, we installed the Mosquitto MQTT broker. Now we'll test it which we’re going to do on the same machine that Mosquitto is running on. First, you’re going to need to install the Mosquitto client tools:sudo apt-get install mosquitto-clients Now, let’s run Mosquitto from the command line:root@deb-01:/home/mgibbs# mosquitto 1485602498: mosquitto version 1.3.4 (build date 2014-08-17 03:38:31+0000) starting 1485602498: Using default config. 1485602498: Opening ipv4 listen socket on port 1883. 1485602498: Opening ipv6 listen socket on port 1883. The Mosquitto broker is now listening on the standard MQTT port, 1883, for both IPv4 and IPv6 MQTT requests. Next, open a new terminal window and enter:To read this article in full or to leave a comment, please click here

APIC-EM Data Export

I was at a Cisco DNA customer event on Thursday. Someone in the audience asked a very good question. Basically they wanted to know if there was a way to extrapolate data from the APIC-EM network management tool. At first glance it didn’t seem to be something that was available in the UI. One of the Cisco representatives quickly and correctly stated that it APIC-EM to Excelis all available from the API.

My initial thought was that this was a product weakness. Why can’t we just manually extract this stuff to a CSV and import it wherever we want to? Whether due to intentional omission or strategic direction, an API first approach is better. It is better because it allows systems to be glued together and more of our mindless tasks to be automated. So the counter argument to that really revolves around use cases, initial effort and skills gaps. The examples I’m about to provide should help alleviate some of those concerns.

TL;DR — Looking to get APIC-EM data into an Excel spreadsheet? Python can easily grab Host and Device Data and provide it in a format that is easily consumable such as Text, Tab, CSV or other format of choice.

A burden of many #NETCONF articles and tutorials is that they are often silent about the #YANG part. This is why we would like to highlight this post by Michael Kashin called ""Getting Started With NETCONF and YANG"" [1]. Not only this article covers the basics of network elements configuration via NETCONF (particularly via python

Skylake Xeon Ramp Cuts Into Intel’s Datacenter Profits

Every successive processor generation presents its own challenges to all chip makers, and the ramp of 14 nanometer processes that will be used in the future “Skylake” Xeon processors, due in the second half of this year, cut into the operating profits of its Data Center Group in the final quarter of 2016. Intel also apparently had an issue with one of its chip lines ­– it did not say if it was a Xeon or Xeon Phi, or detail what that issue was – that needed to be fixed and that hurt Data Center Group’s middle line, too.

Still, …

Samsung Galaxy S8: Leaks, rumors and fake news

Samsung will not be launch its new Galaxy flagship phone, the S8, next month at Mobile World Congress like it usually announces new Galaxy flagships. The launch is delayed until March 29.The delay did not slow the January leaks, rumors and fake news about the new device, though, including leaked images showing the Galaxy S8 will have a USB C port, an almost bezel-less display and, OMG, a 3.5-inch jack that we may hear about every day in the news during the post-launch week because of the attention the iPhone 7 received for not having one.To read this article in full or to leave a comment, please click here

Docker Online Meetup recap: Introducing Docker 1.13

Last week, we released Docker 1.13 to introduce several new enhancements in addition to building on and improving Docker swarm mode introduced in Docker 1.12. Docker 1.13 has many new features and fixes that we are excited about, so we asked core team member and release captain, Victor Vieux to introduce Docker 1.13 in an online meetup.

The meetup took place on Wednesday, Jan 25 and over 1000 people RSVPed to hear Victor’s presentation live. Victor gave an overview and demo of many of the new features:

  • Restructuration of CLI commands
  • Experimental build
  • CLI backward compatibility
  • Swarm default encryption at rest
  • Compose to Swarm
  • Data management commands
  • Brand new “init system”
  • Various orchestration enhancements

In case you missed it, you can watch the recording and access Victor’s slides below.

 

Below is a short list of the questions asked to Victor at the end of the Online meetup:

Q: What will happened if we call docker stack deploy multiple times to the same file?

A: All the services that were modified in the compose file will be updated according to their respective update policy. It won’t recreate a new stack, update the current one. Same Continue reading

Microsoft’s shell game: 2 new ways to deploy Windows 10

Microsoft is rumored to be working on two new “shells,” but they should not be confused with PowerShell, which is replacing CMD as the primary prompt in Windows 10. While the term “shell” is being used interchangeably, these shells are more like an interface than a command line. First is a single, unified, “adaptive shell” for Windows 10, while the second will actually be a lightweight version of Windows 10. The unified adaptive shell is called “Composable Shell,” or CSHELL. According to a report from Windows Central, which cites unnamed sources, Microsoft's new universal shell will be a single Windows 10 experience that can adapt and scale to the device it’s on, from a phone to a PC. To read this article in full or to leave a comment, please click here

Worth Reading: IOS/XR in GNS3

Cisco IOS XRv is one of the most popular platforms among network engineers. However, this platform is only available in high-end devices, which might not be available to all engineers. For this reason, engineers prefer to virtualize the OS and GNS3 is one of the most popular network simulators to do this. GNS3 is based on Dynamips, Pemu/Qemu and Dynagen. Simulating Cisco IOS in GNS3 is pretty straightforward. Simulating the XR platform is not. But with new XRv image and a few tweaks, you can now run Cisco XR platform in GNS3. —APNIC

Five arrested for hacking into ATMs and stealing $3.2 million

Law enforcement authorities from Europe and Asia have arrested five members of an international cybercriminal group that specialized in hacking into automated teller machine (ATMs).The investigation began in early 2016, according to Europol. Three suspects were arrested in Taiwan, one in Romania, and one in Belarus. Most of them had multiple citizenships and could travel easily between countries, the agency said Friday.Hacking into ATMs to steal money is nothing new, and there are malware programs built specifically for such machines that allow criminals to withdraw money using hidden commands.To infect ATMs with such malware most attackers either receive help from bank insiders or buy service keys that can be used to open the front panels of ATMs and access their communications ports.To read this article in full or to leave a comment, please click here

Fragmentation nixed a Cisco-Android network partnership

Cisco Systems tried to give Android devices the same kinds of integration it later provided for iPhones and iPads but gave up because the Android ecosystem was too fragmented.A Cisco-Apple partnership announced in 2015 gives iOS devices capabilities that other wireless clients don’t have on Cisco-based enterprise networks. Among other things, enterprises can designate work-related applications like videoconferencing for priority on the wireless link between iOS devices and a Wi-Fi access point.To read this article in full or to leave a comment, please click here
