Transitioning to Let’s Encrypt wildcard certificates

A month ago I issued a wildcard certificate for *.paranoidpenguin.net and patiently awaited the expiration of my old HPKP policy. Eventually the time to install the new key and certificate arrived, but to my great dismay, things did not turn out according to plan. Upon restarting the Apache web server, I got served with the following (epic) failure:

AH01909: www.blog.paranoidpenguin.net:443:0 server certificate does NOT include an ID which matches the server name

Zapping crashed services on Gentoo Linux

While configuring my first Gentoo VPS I somehow managed to crash a service and discovered that I had actually no idea how to recover it. The service no longer had any matching processes but it still refused to stop, and simultaneously insisted it was already started. Severely embarrassed I made sure nobody was looking and rebooted the server.

There are still privacy concerns with GNOME Software

I recently read a thread on reddit titled “A Privacy & Security Concern Regarding GNOME Software” that addressed a few issues regarding the fwupd daemon. The developer eventually responded and was able to justify and debunk most of the claims made against his software. However, that prompted me to have a closer look at the traffic originating from GNOME Software.

Rickrolled by Google Search Console

So I noticed this new “Recrawl now” link that had suddenly appeared in Google Search Console (beta edition) and was immediately enticed. The result however was not what I had in mind. I can deal with being fooled on April Fool’s day, but getting Rickrolled in 2018… now that’s just pure evil. Anyhow, enjoy an animated gif of Google’s trolling below.

macOS Sierra review – Behind enemy lines

I’ve never owned a single Apple product but lately I’ve been wondering how good a real UNIX certified operating system might actually be. To get my feet wet, I decided to try out macOS Sierra in a VirtualBox session on a Linux host. I’m aware that much of the Apple experience is closely connected to the hardware, but personally I was more interested in the isolated OS experience.

Arch Linux boot halts on Reached target Multi-User System

Arch pushed out Gnome 3.28 today but unfortunately for me, my system failed to boot properly after the upgrade. The system simply locked up after the “Reached target Graphical Interface” stage. GDM (The GNOME Display Manager) was a prime suspect in my book, so the first order of business was booting into a lower runlevel to figure out what was going on.

BlueOnyx 5209R – Issues with importing signed certificates

Importing signed certificates on BlueOnyx has always been somewhat of a challenge and it’s not well documented. The gist of it is that the certificate you want to import needs to consist of both the certificate and the corresponding private key, and it must have an extension that BlueOnyx understands (*.crt or *.cert works). Even so, my attempt to import a signed certificate from RapidSSL failed with a message stating that the imported certificate did not contain the correct private key.

Unexpected VPN bypass attempts on Arch Linux

So I was minding my own business while connected to my VPN service when I noticed several blocked outbound network connections appearing in my firewall log. For some reason my wifi adapter (wlp3s0) was trying to connect directly to the internet without having traffic routed through my VPN interface (tun0). Was this my reward for not reviewing AUR PKGBUILD files, or was there another explanation as to why wlp3s0 wanted to disclose my real IP address?

Another significant WordPress brute-force attack in the works

So today I’ve experienced a more significant than usual attack against WordPress installations hosted on one of our company servers. So far I’ve blocked more than 17000 21000 unique IP addresses, but the attackers seem to have an endless supply and they’re not slowing down. Note: This article was updated on January 27, 2018.
