Connecting VIRL to the Outside World

I’ve been leveraging VIRL for some time to build and test self-contained labs. I’ve always known that there was some ability to connect to the world outside of this environment. Recently, I decided to configure this functionality and I wanted to take just a moment to share what I found.

First and foremost, this isn’t anything difficult or time consuming. So if you have a need to leverage physical devices with your VIRL deployment, don’t hesitate before building it out.

There are two mechanisms for outside connectivity. The first mechanism is called SNAT. This method basically builds static NAT in and out of the environment. I get how this could be beneficial, but I would typically prefer to keep any NAT configuration contained to an environment that I am very familiar with (possibly an ASA or IOS instance outside the lab when an additional NAT layer is required).

The second method, and configuration we will be testing is called FLAT. In this configuration, VIRL connects a L2 broadcast domain between a lab device and an Ethernet interface. In my example I am running the VIRL components in a VM environment on ESXi. So this is a virtual interface that needs Continue reading

Using free Yandex DNS service in an automated way

This DNS story started when I bought a domain with a specific need — to dynamically create and delete DNS records for Nuage Networks components we use during Proof Of Concepts and customers trials. Earlier I used to rely on Dynamic DNS services (i.e. no-ip.com) whenever I needed a DNS name for my public endpoints. But this approach has two

The Grugq, Hacker House and ‘Boceffus Cleetus’ weigh in on the latest ShadowBroker dump

If you enjoy good security-related reads, then you might like to check out a couple different takes on the latest ShadowBrokers’ NSA-linked Equation Group auction files. One comes from “the grugq,” a security researcher who is well-respected for his infosec and counterintelligence knowledge, and the other is by the cybersecurity researchers at Hacker House out of the UK.The Grugq published a three-part commentary series on the great cyber game – part 1, part 2, part 3. His deep analysis is his contribution since not many are capable of it. He said that the latest by the ShadowBrokers, dropped on Dec. 14, is a “massive” and valuable drop in terms of revealing to the NSA what the Russians know and have obtained.To read this article in full or to leave a comment, please click here

IP Networking – generational shift in the industry to pure-L3 network stack

© Calico project (http://docs-archive.projectcalico.org/en/1.4.3/addressing.html)
After years and years of innovation, the networking industry is changing. IPv6 is now slowly being adopted - both by interest and need. With all of IPv4 addresses having been exhausted it is now a mandate on the requester to either move to IPv6 or pay a hefty premium for repurchase of v4 addresses. On the other spectrum I believe that Calico and other projects that do pure L3 only networking, is a newer approach to network segregation; not just solving specific problems in the networking infra but a trend that will slowly be adopted widely in the network community. This is mainly also because of IPv6 acting as a booster to moving to a L3 pure play networking solution. This move to L3 only networking can be seen across the infra stack - from physical servers to VMs to containers.

Docker networking eco-system begun with libnetwork and after that has propagated with multitude of solutions by both community and networking vendors. Unlike Flannel (CoreOS) and VXLAN which leverage tunneling and L2 protocols, Calico is a distributed L3 networking solution that works both with Virtual Machines and Continue reading

Obama vows to punish Russia over election-related hacks

U.S. President Barack Obama pledged to punish Russia for hacking of Democratic groups and figures during the election season with actions that’ll occur in secret and others that’ll be made public.“Our goal continues to be to send a clear message to Russia or others not to do this to us because we can do stuff to you,” Obama said in a press conference.The President stopped short of explicitly blaming Russian president Vladimir Putin for directing the alleged hacks, but said that, “not much happens in Russia without Vladimir Putin.”Obama met Putin during a summit in China in September and told him to "cut it out" and or else "there would be some serious consequences if he didn't," he said. After that meeting, the hacking attempts stopped but Wikileaks had already been given copies of stolen documents.To read this article in full or to leave a comment, please click here

Zinc launches new tools for putting workers on blast

Zinc, a messaging platform for businesses, announced Friday that it is launching a set of new features aimed at helping desk-less workers get the most out of enterprise instant messaging. First off, the company is launching Broadcasts, a way for businesses to send employees rich notifications that block out all of the other messages and force users to close then before they can resume messaging. Administrators will be able to see which employees have seen and dismissed the notification. In addition, the company rolled out support for Organizations, which let administrators subdivide all of the Zinc users in their company into a set of smaller groups.To read this article in full or to leave a comment, please click here

Worth Reading: The bandwidth paradox

If consumers are always on, so is the data center. From mobile applications to wearables, the number of devices that are always connected continues to grow. Surprisingly, many consumers don’t understand that behind wicked-fast music downloads, YouTube video streaming or an instantaneous ride from Uber, data centers are at the forefront of this always-on movement. Without the compute capacity and agile power-management options, these services would simply be impossible. —Data Center Journal

Businesses eye cloud for big data deployments

As 2016 draws to a close, a new study suggests big data is growing in maturity and surging in the cloud.AtScale, which specializes in BI on Hadoop using OLAP-like cubes, recently conducted a survey of more than 2,550 big data professionals at 1,400 companies across 77 countries. The survey was conducted in conjunction with Cloudera, Hortonworks, MapR, Cognizant, Trifacta and Tableau.[ Analytics 50 winners for 2016 ] AtScale's 2016 Big Data Maturity Survey found that nearly 70 percent of respondents have been using big data for more than a year (compared with 59 percent last year). Seventy-six percent of respondents are using Hadoop today, and 73 percent say they are now using Hadoop in production (compared with 65 percent last year). Additionally, 74 percent have more than 10 Hadoop nodes and 20 percent 20 percent have more than 100 nodes.To read this article in full or to leave a comment, please click here

IDG Contributor Network: IoT-based precision agriculture reduces the guesswork in farming

“Whoever makes two ears of corn, or two blades of grass to grow where only one grew before, deserves better of mankind, and does more essential service to his country than the whole race of politicians put together”.Steven Valenscin, the founder of Growers exemplifies this 400-year-old quote by Jonathan Swift.Steven grew up working on his family farm in Washington State. After serving in the US Navy, He started North Carolina’s first private soil testing laboratory and then combined his passion for soil fertility and farming to found Growers. Steven aims to simplify the complex world of agronomy into precise farm management decisions.To read this article in full or to leave a comment, please click here
