Troubleshooting Application Configuration for Security
In this video, Tony Fortunato uses Wireshark to show you how to get an application to run through a firewall.
Updated: First Set of Building Next-Generation Data Centers Self-Study Materials
When I started the Building Next-Generation Data Centers online course, I didn’t have the automated infrastructure to support it, so I had to go with the next best solution: a reasonably-flexible Content Management System, and Mediawiki turned out to be a pretty good option.
In the meantime, we developed a full-blown course support system, included guided self-paced study (available with most ipSpace.net online course), and progress tracking. It was time to migrate the data center material into the same format.

Four years ago we started looking at the level of support for ECDSA in DNSSEC. At the time we concluded that ECDSA was just not supported broadly enough to be usable. Four years later, let's see if we can provide an updated answer to the question of the viability of ECDSA.NSX Sessions to geek out at VMworld 2018
VMworld 2018 is around the corner and we have an exciting lineup of over 80+ breakout sessions, customer deployment stories and Hands-on Labs for you from the VMware NSX family!
For the tech nerds interested in deep-dives and deployment strategies, we have a list of recommended “geek” NSX VMworld 2018 sessions to choose from in various focus areas.
Security:
Deep Dive into NSX Data Center Security for Clouds, Containers, and More [SAI1527BU]
Speakers: Ganapathi Bhatt
This technical session will focus on key security features and use cases for VMware NSX-T Data Center in a multi-hypervisor, heterogeneous workload environment (VMs, containers, bare metal), the architecture and implementation of NSX-T distributed firewalls and edge firewalls, and the grouping/policy model for NSX-T Data Center. You will also find out how VMware NSX Data Center extends a uniform security policy model to VMware NSX Cloud and VMware Cloud on AWS environments.
Securing Horizon and Citrix End-User Computing with NSX Data Center [SAI1851BU]
Speakers: Geoff Wilmington
Organizations deploying virtual desktop infrastructures are tasked with designing for security, networking, and network services for this infrastructure. This can be a complex design process and include multiple products to meet the requirements. When coupling VMware NSX Data Continue reading
Instructor Spotlight: Keith Bogart
Keith Bogart is one of INE’s most esteemed and experienced instructors. Keith has been with INE for 4 years designing and instructing videos and bootcamps, as well as hosting live web-series, designing workbooks, and contributing to our IEOC Forum and INE Blog. Keith has a CCNA in Routing and Switching, CCIE in Dial-ISP, CWNA and is currently working towards his CCNA Security certification.
Before he was with INE, Keith worked as a service representative, technical assistance engineer and network consulting engineer at Cisco Systems. After 17 years at Cisco and a short time with a small start-up, Keith brought his talents to INE and became our #1 CCNA Routing & Switching instructor.
So what has Keith been up to?
On a typical day you can find Keith in our North Carolina office working on his latest project – a new CCNA Security Bootcamp. This bootcamp is still in its early stages of design, however, according to Keith, it’s shaping up to be a 5-day Bootcamp that will be offered online at least twice in the first half of 2019.
PrettyTable – Printing anything in Table
Hi,
As the scripting and programming deals in logging into the device and fetching data, there will be a time where presentability of Data matters. PrettyTable is one such package which greatly helps in reading things
A simple example, re-visiting the code to get the list of routes from the Device
PrettyTable will help in tabulating the Data, the installation and usage can be found here
Pip Package – https://pypi.org/project/PrettyTable/
Usage – http://zetcode.com/python/prettytable/
Once we have the code, let take a look at how the program looks
The Table form looks something like this
Hope this help for anyone who gets started with presentability of Data, honestly, there was one time I got crazy with the print statement just to make the data presentable.

Cisco Says Its Open vRAN Alliance Is Behind the Latest xRAN Forum Spec
There is a lot of work required to virtualize the RAN and standards groups like the xRAN/O-RAN Alliance and the 3GPP can’t do it all, says Cisco.
Instana Tailors Its APM to Each Enterprise User
More users need access to APM tools because of the growing complexity of architectures. Instana developed a tool to personalize APM tools for specific users.

Research: Are We There Yet? RPKI Deployment Considered
The Resource Public Key Infrastructure (RPKI) system is designed to prevent hijacking of routes at their origin AS. If you don’t know how this system works (and it is likely you don’t, because there are only a few deployments in the world), you can review the way the system works by reading through this post here on rule11.tech.
The paper under review today examines how widely Route Origin Validation (ROV) based on the RPKI system has been deployed. The authors began by determining which Autonomous Systems (AS’) are definitely not deploying route origin validation. They did this by comparing the routes in the global RPKI database, which is synchronized among all the AS’ deploying the RPKI, to the routes in the global Default Free Zone (DFZ), as seen from 44 different route servers located throughout the world. In comparing these two, they found a set of routes which the RPKI system indicated should be originated from one AS, but were actually being originated from another AS in the default free zone.
What do you believe now that you didn’t five years ago?
Decentralized systems will continue to lose to centralized systems until there's a driver requiring decentralization to deliver a clearly superior consumer experience. Unfortunately, that may not happen for quite some time.
I say unfortunately because ten years ago, even five years ago, I still believed decentralization would win. Why? For all the idealistic technical reasons I laid out long ago in Building Super Scalable Systems: Blade Runner Meets Autonomic Computing In The Ambient Cloud.
While the internet and the web are inherently decentralized, mainstream applications built on top do not have to be. Typically, applications today—Facebook, Salesforce, Google, Spotify, etc.—are all centralized.
That wasn't always the case. In the early days of the internet the internet was protocol driven, decentralized, and often distributed—FTP (1971), Telnet (<1973), FINGER (1971/1977), TCP/IP (1974), UUCP (late 1970s) NNTP (1986), DNS (1983), SMTP (1982), IRC(1988), HTTP(1990), Tor (mid-1990s), Napster(1999), and XMPP(1999).
We do have new decentalized services: Bitcoin(2009), Minecraft(2009), Ethereum(2104), IPFS(2015), Mastadon(2016), and PeerTube(2018). We're still waiting on Pied Piper to deliver the decentralized internet.
On an evolutionary timeline decentralized systems are neanderthals; centralized systems are the humans. Neanderthals came first. Humans may have interbred with neanderthals, humans may have even killed off the neanderthals, but Continue reading
