In late 2023, I started playing with the idea of having automated validation in netlab. The early implementation was used in BGP labs, and a user liked it so much that he opened an issue saying:
I would suggest providing netlab validate for each lab.
Numerous rounds of yak-shaving later, I merged a humongous commit that adds automated validation to these lab exercises:

This Friday at 1pm ET, Bruce McDougall and I are teaching a live class on using Containerlab to build and automate network labs. From the course description:
This course will guide learners through the tools and techniques to build virtual labs either locally or on common cloud services, so you can become more proficient at understanding, designing, monitoring, and troubleshooting networks. The course begins with obtaining and starting the basic tools required to build and test network labs using open-source and freely available tools. The instructors will build a variety of network topologies, including data center and campus, to help learners understand how to test in different environments.
During the ITNOG8 netlab presentation, I jokingly said something along the lines “all that’s missing is RIPv2 and Babel.” That’s no longer true; someone asked me how hard it would be to add RIPv2 to netlab, and I said, “give me a few days 😎”
Other new features in netlab release 1.8.3 include support for BGP route servers (and route server clients), BGP Link Bandwidth community, and OSPF/BGP validation plugins for Arista EOS, Cumulus Linux and FRR. We also fixed the installation scripts to work with Ubuntu 24.04 and Debian Bookworm.
For more details, read the release notes.

In part 2 of this multipart series on network observability with SuzieQ, we looked at how to setup SuzieQ using docker compose. In this part, we will look at how to interact with the data collected by SuzieQ using the command line interface (CLI) and its REST API.
If you have not read Part One and Part Two yet, I recommend you read it first before proceeding with this part.
SuzieQ provides a command line interface to interact with the data it has collected. Like any Linux CLI, SuzieQ CLI providers command completion when options are available and also provides help for each command. All commands follow a common structure <table_name> <verb> <filters>. This will make more sense when we start looking at some examples.
Let us start by running the SuzieQ CLI. If you have been following along with the previous parts, you should have the SuzieQ docker container running and you can connect to the SuzieQ CLI by running the docker attach suzieq_cli command. Once you are connected, you will see a prompt like this suzieq>. This is the SuzieQ CLI prompt.
root@sudarshanv:/suzieq/suzieq# docker attach suzieq_cli
suzieq>Connecting to SuzieQ CLI

If you work with Palo Alto firewalls, you might know there's no straightforward way to find and remove unused address objects. When I googled for solutions, I found that others suggested using Expedition or some kind of automation. In this blog post, I'll show you a very simple script to find these objects and remove them if needed.
I tried using Expedition a few years back, but it required a dedicated VM, and I struggled to wrap my head around how to use it. I just needed a simple solution. While I could also use Palo Alto's REST API or even the Python SDK, setting everything up takes a bit more time.
Then it occurred to me that Palo Alto provides 'set' commands, and you can use the 'delete' version of those commands to remove something. With that in mind, I thought, "Hmm, what if I get the whole config from either the firewall or Panorama in the 'set' format, run it through a regex, and extract all the object names?" Once I have the object names, I can go through the configuration line by line to check if the objects are Continue reading
Richard Solomon has heard the rumblings over the years. As vice president of PCI-SIG, the organization that controls the development of the PCI-Express specification, he has listened to questions about how long it takes the group to bring the latest spec to the industry. …

You will probably be laid off at least once in your career–we no longer live a world of “permanent positions,” or even a world where people are in complete control of their “work destiny.” It’s important, then, to prepare to be laid off, made redundant, or impacted by a RIF, today. Mike Bushong joins Eyvonne Sharp, Tom Ammon, and Russ White in a wide-ranging discussion about preparing to be laid off.
Here is something we don’t see much anymore when it comes to AI systems: list prices for the accelerators and the base motherboards that glue a bunch of them together into a shared compute complex. …
