MinIO ist eine freie Implementierung des Amazon Simple Storage Services (kurz: S3), womit sich Dateien als Objekte “kübelweise”, d.h. in sogenannten Buckets, ablegen lassen. Weitere Hierarchiestufen gibt es nicht; auch die Berechtigungen lassen sich nur auf Stufe Bucket festlegen.
In diesem Artikel soll gezeigt werden, wie sich MinIO in Betrieb nehmen und mit dem MinIO-Client mc ansprechen lässt. Hierzu soll wie bereits im spiped-Artikel das Herr der Ringe-Universum zur Veranschaulichung dienen ‒ und Debian 12 “Bookworm” als Betriebssystem.

Zur sicheren Datenübertragung einzelner Nachrichten hat sich PGP/GPG etabliert. Für gesicherte, d.h. verschlüsselte Verbindungen gibt es SSH. Eine SSH-Sitzung wird jedoch unterbrochen, wenn die TCP-Verbindung abbricht. Der Secure Pipe Daemon (spiped) arbeitet als Daemon, wodurch man es mit einer beständigen, verschlüsselten Datenverbindung zu tun hat.
Im Gegensatz zu GPG und SSH kommt jedoch bei spiped eine symmetrische Verschlüsselung zum Einsatz. Der gemeinsame Schlüssel muss also vor Verbindungsaufnahme über einen sicheren Kanal ausgetauscht werden.

I’ve been using Arch Linux since 2016. I got to understand the system better since then, and installing Arch nowadays is rather a strain on my fingers than on my brain. I automated my personal setup procedure to some extent with a couple of shell scripts, which I’m adjusting as time goes and hardware changes. I collect those scripts and setup instructions in a GitHub repo.
Even though I’ve often taken my laptop with me, especially for university, I never made the effort to encrypt my disk or a single partition thereon.

I have a roughly ten year old Brother HL-5370DW printer on the shelf next to me. This printer is mostly used by my wife to print sewing patterns. When I was studying computer science, I sometimes printed documents I’ve written for proofreading. I often was able to find typos that I didn’t see on the screen even after proofreading the document two or three times. However, I didn’t bother to print out my bachelor thesis.

I’ve been using the Swiss keyboard layout for most of my life. Things changed when I first had to work on a Mac Book. If the Swiss keyboard layout is not great for programming on a usual keyboard, because it requires combinations with Alt-Gr to type in braces and brackets, I consider the Mac version of it outright horrible, because braces and brackets are located on the digits row. Those symbols are not even painted onto their respective keys, which makes the transition for non-Mac users even harder.

A week ago, I’ve installed OpenBSD on my Thinkpad. I’ve been using it now and then, and already have changed a couple of things in respect to the original setup described in the article. I also installed OpenBSD on the Dell Optiplex on which I previously installed FreeBSD a month before. This means that I’m no longer using FreeBSD on the desktop, at least not for the moment. However, FreeBSD is running on a disk station I built earlier this summer.

Let’s install OpenBSD on a Lenovo Thinkpad X270. I used this computer for my computer science studies. It has both Arch Linux and Windows 10 installed as dual boot. Now that I’m no longer required to run Windows, I can ditch the dual boot and install an operating system of my choice.
Preparation First, I grab my work Thinkpad running Arch Linux and some USB dongle big enough for the amd64 miniroot image (roughly five megabytes, that is).

I’m a happy user of Arch Linux both on my private computers and on my work laptop. I even managed to get through four years of university with my setup, and only had to bring a Windows machine on some rare occasions, even though some professors are openly hostile towards a Linux setup. (It doesn’t run Microsoft Project and the real Excel, after all…)
Recently, I got interested in the BSDs, especially in OpenBSD and in FreeBSD.

I’d like to dig deeper into system administration tasks. At work, I have to manage a fleet of Linux servers with Puppet. And in my spare time, I’d like to manage the servers I run with Ansible or Puppet in the future.
Virtual Machines are easily obtained nowadays. Cloud providers such as Digital Ocean or Exoscale offer virtual machines with various operating systems at rather moderate prices. You only have to pay for the time the virtual machines are actually running, so you can save money by shutting those hosts down when not needed.

Ich verwende seit 2005 hauptsächlich Linux als Betriebssystem. Dabei habe ich schon Erfahrungen mit verschiedenen Distributionen sammeln können. Meistens hatte ich eine Hauptdistribution, die praktisch auf all meinen Rechnern installiert war. Dies ändert sich jetzt vielleicht. Doch der Reihe nach…
Mandrake: Wie alles begann Meine ersten Erfahrungen mit Linux habe ich im Jahr 2004 gemacht. Alles begann damit, dass eMule (das damals wichtigste File-Sharing-Tool, das einen Stellenwert hatte, wie es heute BitTorrent hat) auf dem Windows-Rechner der Familie nicht mehr richtig funktionierte.
