Cloud Engineering For The Network Pro: Part 3 – VPCs And Virtual Networks (Video)
The next installment of Michael Levan’s series on networking in public clouds walks through how to set up a VPC (Virtual Private Cloud) in AWS and a VNet (Virtual Network) in Microsoft Azure. You can subscribe to the Packet Pushers’ YouTube channel for more videos as they are published. It’s a diverse a mix of […]

Tech Bytes: How Fortinet’s FortiGuard Labs Turns Billions Of Security Events Into Intelligence (Sponsored)
Today’s Tech Bytes podcast explores threat intelligence with sponsor Fortinet and its FortiGuard Labs. FortiGuard Labs analyzes billions of global security events daily and distills them into actionable information for network and security teams. Fortinet also uses those events to inform security updates to its products.

This post originally appeared on the Packet Pushers’ Ignition site on October 19, 2020. The network edge is desirable new territory for software and hardware vendors. The objective is to get compute, networking, storage, and security features as close as possible to data sources and data-hungry applications. VMware and NVIDIA have launched new initiatives to […]

Network Break 371: Arista Turns Campus Switch Into NDR Sensor; Mikrotik Puts A Router On A PCIe Card
Take a Network Break! This week we examine how Arista is turning a campus switch into a sensor for network detection and response, a new PCIe card from Mikrotik running router software, a Dell/Marvell partnership on hardware for Open RAN gear, Cisco and Dell financial results, potential equipment danger from solar flares, and more.Topology aware fabric analytics

Running a Ubuntu VM on a Mac M1
If you’re brand-new to Python and Ansible, you might be a bit reluctant to install a bunch of packages and Ansible collections on your production laptop to start building your automation skills. The usual recommendation I make to get past that hurdle is to create a Ubuntu virtual machine that can be destroyed every time to mess it up.
Creating a virtual machine is trivial on Linux and MacOS with Intel CPU (install VirtualBox and Vagrant). The same toolset no longer works on newer Macs with M1 CPU (VMware Fusion is in tech preview, so we’re getting there), but there’s an amazingly simple alternative: Multipass by Canonical.

A Bird feeder from re-usable plastics – we have to start something small to protect other beings.
Disclaimer: I speak about reducing plastic and still I use a 3d printer to print a very specific fixture, I have weighed in options and plastic that I end up printing will be out there hopefully feeding birds or can safely be re-cycled until I come up with something innovative, as of now this is the least I could come upon re-using old bottles, helping birds feed and using some plastic to print a fixture. If I have to buy a commercial one, that is again some plastic and I won’t end up re-using it as well, so 3d printing this small fixture for me outweighs the other currently viable solution and this is something I can give out to neighbours and they can easily associate with.
Am proud to say that I have started to take some responsibility towards the environment and other living beings, that to say it’s my first step and now I appreciate even more what environmentalists and other people do to protect other beings, earth and fellow human beings which we don’t have any time to notice and appreciate them.
Once I started doing the below things which are very trivial I feel good and Continue reading
ExtraHop Bridge Triggers
Recently, I was working with a customer that wanted to extract the TCP SYN unanswered in/out metric captured by Extrahop for a group of web servers and send that data to Splunk so their application team could view the data in a Splunk dashboard. It was an interesting problem to solve...continue reading
AWS: The Case of the iBGP Peer that Worked – Part 1: The Facts
I was so surprised when the BGP neighbor came up. I kinda just blinked and stared at it for awhile. I knew it couldn’t be an AWS bug. This was just too basic a setup. Did I misconfigure something? If... Read More ›

I had a fun exchange on Twitter this week that bears some additional thinking. Emirage (@Emirage6) tweeted a fun meme about learning BGP:
Okay, it's decided. This is how I am going to handle BGP in the future

— Emirage (@Emirage6) February 22, 2022
I retweeted it and a few people jumped in the fun, including a couple that said it was better to configure BGP for reasons. This led to a blog post about routing protocols with even more great memes and a good dose of reality for anyone that isn’t a multi-CCIE.
Explain It Like I’m Five
I want you to call your mom and explain BGP to her. Go on and do that now because I’m curious to see how you’d open that conversation. Unless your mom is in networking already I’m willing to bet you’re going to have to start really, really basic. In fact, given the number of news organizations that don’t even know what the letters in the acronym stand for I’d guess you are going to have a hard time talking about the path selection process or leak maps or how sessions are established.
Now, try that same Continue reading
