Arista AVD (Architect, Validate, Deploy) – https://avd.arista.com – is a powerful tool that brings network architecture into the world of Infrastructure-as-Code. I wanted to try it out in a lab setting and see how it works in a non-standard environment. Since my go-to lab tool is GNS3 with Arista cEOS images — while the AVD […]

I have a bit of a problem with this setup serving phpIPAM via Nginx reverse proxy, so I said to share the solution which works for me here maybe will help somebody out there. I installed phpIPAM as Docker container following the instructions here: https://github.com/phpipam-docker/phpipam-docker. Using it via plain http was working OK, but I […]

I’m using Mac at work and I found out that Kerberos needs sometimes a “kick” for the SSO to work properly. Sometimes after being offline the renewal of Kerberos ticket fails (especially when remote and connected via ZTA or VPN), even though everything looks alright in the “Ticket Viewer” app. Here is we where the […]

This post will be a very short one, more like a note :) Based on the LFNE Docker images (explained here https://ipnet.xyz/2023/11/lfne-linux-for-network-engineers) I’ve created the GNS3 Appliances for easy import into GNS3. The GNS3 Appliances can be downloaded here https://github.com/yotis1982/lfne and imported into GNS3. Have fun!

Formerly known as PFNE – Python For Network Engineer, the images developed to be more than just for Python learning. My choice was to call the new one more generic and pick the Linux For Network Engineers (LFNE) Linux images build with all tools need by network engineers to perform various tasks ranging from simple […]

Lately I’m looking more and more into Python, with respect to automation implementations useful for network engineers. In the learning process I’ve used different materials, like the excellent video trainings Python Programming for Network Engineers from David Bombal which are available free on Youtube.
This training in particular relies on a Ubuntu Docker image in order to support Python learning following interaction with Cisco devices in GNS3. Everything is great, just that the image doesn’t contain all necessary tools (like Paramiko, Netmiko, Ansible…). As you can guess, whenever you close / open the Project in GNS3, all the installed packages installed in the Ubuntu Docker image are gone.
Since we’re talking automation, I got bored to install the necessary tools everytime I wanted to start a new project or I had to close GNS3 for some reason. I’ve tried to find a Docker image that suits my needs, but I couldn’t (please point me to one if you know it).
So, I’ve build a Docker image, based on Ubuntu 16.04, which contains the necessary tools to start learning Python programming oriented for network engineers:
