Automation and programmability is not a new topic for me. Having studied Information Technology in High School I’ve always coded somehow, never making it my primary focus but always using it as a tool to make my life easier.
I remember a script I did in Pascal to create a menu to load custom maps for Doom II instead of using the CLI. It would be great to find it again but it’s very unlikely because I trashed so many PCs and hard drives since, well, at least I hadn’t bitcoins stored there!
For a Network Engineer living and working on the field has some challenges that are not common in office environments.
I have a set of tools, hardware and software, that I bought or built over the years that allow me to accomplish my job in more effective way.
I used to carry a small Access Point to provide connectivity inside a datacenter or campus when the rack is located in odd places (you know what I mean).
We live in a time of intent, automation, orchestration and a lot of wonderful tools that promise to make the life of network engineers easier.
Sometimes reality is simpler and maybe less fascinating, real problems need to be solved quickly with small budget.
The specific case I discuss here is a medium network, around a hundred devices. The problem is to create an inventory of all the devices, backup configurations and verify all the boxes have the correct syslog, ntp and timezone configuration.
I had the honor and pleasure of being invited again to attend Tech Field Day, this time for an Extra event at Cisco Live Europe in Barcelona.
Cisco Live is a week full of product announcements, technical session, (social) networking with fellow network engineers, meetings with colleagues and customers, discussions with Cisco engineers about products and roadmap. This is exhausting and exciting at the same time but it definitely worth the effort.
My new post about Floating Networks has been published, read it on Aruba Blogs.
Three years in a row, this is great! I’m again a Cisco Champion!
In the previous post of this AirPiConsole series (part1, part2) I used Autossh to create a reverse tunnel from the device to a cloud VPS to permit remote access.
The VPS I use is cheap but unreliable so the tunnel was down most of the time so I started looking for a better alternative.
The solution came from the Packet Pushers podcast episode PQ134 about ZeroTier.
What is ZeroTier?
My new post about Colorless Switches and Mac-Auth has been published, read it on Aruba Blogs.
The future of CLI and how Network Engineers will interact with devices is a topic being discussed quite often:
"I'll give you my CLI when you pry it from my cold, dead fingers" - said no #CCIE ever, they're busy automating their networks with Python to save time for more creative activities.
Just a few of them suffer the "CLI Stockholm Syndrome"https://t.co/jHkB4LQk5T pic.twitter.com/j8CDgCIBpA

At the end of the year it’s quite common to think about the results accomplished and missed on the last twelve months.
Some people say
career is a marathon, not a sprint
and I partially agree. The main difference is a marathon has a predefined path already known since the beginning, a career looks more like connecting the dots but
you can’t connect the dots looking forward; you can only connect them looking backwards
