IT

Python reminds me of PHP many years ago, when multiple incompatible versions could exist on one server. Do you need another version? The best solution back then was a new server, because any update or installation could break the entire global environment. Half a year after the “Sunsetting Python 2”, major distributions still continue to install Python 2 by default, and it becomes a challenge not to replace the default version after some update or after installing a new package.

This was the first time I used FreeRadius. This program reminds me of Postfix — a similarly complicated and powerful tool. Only one big difference: very poor documentation and not enough examples. In the mailing lists there are many questions without answers from FreeRadius gurus. Here I provide examples of how I solved some problems or where I spent too much time…

New project — new challenge. For this project I got UAP-AC-Pro, UAP-AC-Lite and UAP-Outdoor+. How to install and configure them you can easily find on the Ubiquiti website. This post is about the hard way — when you don't buy the full ecosystem and need a custom solution.

Work From Home (WFH)… Not a big problem for IT. Almost everything I need I can do without any discomfort. A good understanding of how to work remotely came during the first quarantine period; in Lithuania it was in summer. Good weather, my own house, lots of forests around… Who cares about COVID-19 — I just stayed with my family and spent my time as usual.

Sometimes even a fully updated Windows server can be compromised. One of the simplest ways to reduce exposure is to place services behind a VPN.

When starting 150+ Docker containers with docker-compose, I encountered a strange problem: "Could not generate persistent MAC address".
