Lab Requirements for Ansible for Networking Engineers Online Course
One of the undergraduate students attending my Ansible for Networking Engineers online course got to the point where he wanted to start hands-on work and sent me a list of questions:
Do I have to buy a VIRL license to use your Ansible course materials? Or is VIRL in any Github repository? Is there a way to use your files in a free Tool like GNS3?
Let’s go through them one by one:

Why ? I am currently using Ubuntu 1604 as the OS on my laptop. It generally works well apart from one thing ... The FRACKING NVIDIA DRIVERS. Nvidia you can go and die in a pit fire. At least 3 or 4 times in the last 6 months the driver update has stopped the system from booting. It gets to a...Extending Ansible action plugins for Cisco IOS
It started out as a question. If you are using several networking modules in a playbook, do you really have to repeat the same credentials on every task? Just like the last few articles about Ansible this one came to life after answering questions in a chat room. The short answer is; No you don’t have to include all of the required parameters for every task, you can use an action plugin to work around that.
Great! So what’s an action plugin? Continue reading
RIPE 75
RIPE held its 75th meeting in Dubai in mid-October. As usual there was a diverse set of presentations covering a broad range of activities that are taking place on today’s Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centres, IPv6, the DNS, routing and network measurement. If that's not enough, the topic of the Internet of Things has been added as a Working Group in the RIPE pantheon. If you add address policy, database and RIPE services to the mix you get a pretty packed five days with topics that would appeal to most Internet folkRIPE 75

It is now almost 12 months since the first announcement that Broadcom was to acquire Brocade, and sell off the IP parts of the business. It took another 6 months to get confirmation that Extreme Networks would be buying my business unit (SRA).
For regulatory reasons, the Broadcom/Brocade transaction has still not closed. The original plan was to close that deal first, then close the Extreme transaction. But due to the delays, they re-arranged things, and now the Extreme deal has finally closed. Desks have been cleared, moving crews are working all weekend, and come Monday, I will have a new “Extreme Networks” badge.
What does this mean for me? My group is moving to become part of Extreme Networks. In the short term, I keep working with the same core group of people. But now we will be part of a new wider group, with a different strategic focus.
We will have new systems and applications to integrate StackStorm with, new use-cases, and maybe further opportunities beyond StackStorm. So far all signs are pointing to this being a positive move, and I am looking forward to getting this transition behind us.
Cisco PIX Security Appliances Firewall modes
Today I am going to talk about the different modes of Cisco PIX firewall. By default if you talk about the mode of the firewall, a firewall is a routed hop and acts as a default gateway for hosts that connect to one of its screened subnets.
Now let's talk about the different firewall modes. There are two modes of firewalls and they are as routed mode and transparent mode.
Cisco PIX Security Appliances Routed mode
Default mode of an ASA. The ASA acts as a single firewall and all interfaces are provisioned to be managed through a single firewall configuration.
Configuration Example for Cisco PIX security appliances in routed mode
Below is the basic way Continue reading
In recent years, a growing best practice has been to deploy firewalls not only at the traditional network perimeter-where the private corporate network meets the public Internet-but also throughout the enterprise network in key internal locations, as well as at the WAN edge of branch office networks. This distributed-firewall strategy helps protect against internal threats, which have historically accounted for a large percentage of cyber losses, according to annual studies conducted by the Computer Security Institute (CSI).
Now let's talk about the different firewall modes. There are two modes of firewalls and they are as routed mode and transparent mode.

Alcatel-Lucent (Nokia) 7750 Service routers
Today I am going to talk about the Alcatel-Lucent 7750 Service routers as they are very much robust in nature and in demand with many of the enterprise networks. Now the Alcatel-Lucent 7750 Service routers are now rebranded and renamed as Nokia 7750 Service routers. The Nokia 7750 service routers are delivers the performance, service richness, and intelligence to drive the converged IP network edge.

MPLS 101 – The Basics
In this series of posts, I want to spend some time reviewing MPLS fundamentals. This has been covered in many places many times before – but I’ve noticed lately that often times the basics are missed or skipped when looking at MPLS. How many “Introduction to MPLS” articles have you read where the first step is “Enable LDP and MPLS on the interface” and they dont actually explain whats happening? I disagree with that being a valid starting point so in this post I’d like to start with the basics. Subsequent posts will build from here as we get more and more advanced with the configuration.
Warning: In order to get up and running with even a basic configuration we’ll need to introduce ourselves to some MPLS terminology and concepts in a very brief fashion. The descriptions of these terms and concepts is being kept brief intentionally in this post and will be covered in much great depth in a future post.
Enough rambling from me, let’s get right into it…
So what is MPLS? MPLS stands for Multi-Protocol Label Switching and it provides a means to forward multiple different protocols across a network. To see what it’s capable Continue reading

5 Strategies to Promote Your App
Brady Gentile from Cloudflare's product team wrote an App Developer Playbook, embedded within the developer documentation page. He decided to write it after he and his team conducted several app developer interviews, finding that many developers wanted to learn how to better promote their apps.
They wanted to help app authors out in the areas outside of developer core expertise. Social media posting, community outreach, email deployment, SEO, blog posting and syndication, etc. can be daunting.
I wanted to take a moment to highlight some of the tips from the App Developer Playbook because I think Brady did a great job of providing clear ways to approach promotional strategies.
5 Promotional Strategies
1. Share with online communities
Your app’s potential audience likely reads community-aggregated news sites such as HackerNews, Product Hunt, or reddit. Sharing your app across these websites is a great way for users to find your app.
For apps that are interesting to developers, designers, scientists, entrepreneurs, etc., be sure to share your work with the Hacker News community. Be sure to follow the official guidelines when posting and when engaging with the community. It may be tempting to ask your friends to upvote Continue reading
