I've build a DNS server which allow me to skip ads, and all those not funny informations. All devises use it as DNS profit from this functionality, mobiles, laptops, ...

This feature is so addictive, that when I must replace his hardware, we can feel how it's annoying to not have it.

I've decided to have 2 machines in a cluster allowing me to never stop the service even during maintenance.

This is really common in our professional servers with paying solutions.

This blog will explain how to it with OpenBSD.

Latest changes in ssh rejects ssh-rsa.

In this post, I'll share some screenshots concerning mysysupgrade.sh script.

This post is linked to the previous one post in October of 2020.

No features has been added, just more details on what it does during the upgrade process

Following my last post I had an interesting conversation about Qterminal: "a lightweight Qt terminal emulator based on QTermWidget".

The discussion was about the "lightweight" of a terminal and the comparison against xterm. But this is not the most interesting part of the discussion. To my eyes, the most interesting feature of Qterminal is the bookmarks.

You just click and the terminal is immediately in the corresponding folder. For a lazy person like me this is fantastic.

Thus, this blog is about Bookmark in KSH.

I'm sharing here some practices I'm following and some small tips/tools which facilitate my usage of OpenBSD in my day to day.

Some a really specific to my usage, others could be re-used.

It's funny to see what does an idle machine. In this blog I compare which websites contacts my OpenBSD laptop with a Windows 10 laptop. I do know very few things of W10, so you can consider it as stock installation. You can see it as a newbie setup.

You have just upgraded your OpenBSD machine to the brand new release, but some of your applications are no more working because they do not have the required python package.

This is a very common problem between python package you have installed via pkg_add and the one you have installed via "pip install". The problem is that both are installed on your machine in /usr/local/lib/python3.8/site-packages.

I propose you a methodology to identify which one were installed with which tool

Since OpenBSD 6.8, boot process does not work on my ASRock J5005-ITX board. The root cause is the kernel size. In this blog, I present you 2 possible solutions

On one of my OpenBSD machine, I had, after several months of usage, a full /tmp filesystem. Despite by checking files, none were big enough to take full space of /tmp. Why df shows a full filesystem ? and why no big files identified by ls, neither by du ?

For the release of OpenBSD 6.8 I've slightly adapted my systupgrade utility.

fzf is an addicting tool for what concerns search. The overall process is very simple, despite very quick. Moreover the tool is well presented. This post will describe how to integrate fzf with OpenBSD packages.

I would like to re-run DragonflyBSD on my laptop where OpenBSD is running. So I'll explain how I've setup a multi-boot system.

After having listen to the presentation of Hannes Mühleisen given on February 2nd at Fosdem. I've decided to give a try to type of DB.

Last week my NAS stopped working. The mother board has not resist to an unplanned power outage. So, I bought a new board J5005. After having placed the new board in the case, I was surprised to see that the board does not see the boot sector. Looking in the documentation of the board, we can ONLY use EUFI. Legacy boot is not supported!!!. Here bellow I will explain how to migrate my disk to UEFI.

Since version 6.6 of OpenBSD we can upgrade a machine via a simple commmand: sysupgrade. Unfortunately this tool as some side effects annoying for me: install all sets and reboot immediately without asking it.
In this blog, I present modifications I did in order to solve those problems.
