Using BurpSuite with qutebrowser

Some time ago I switched to qutebrowser, a keyboard-driven browser based on QtWebEngine. Thus, I had to adapt my BurpSuite setup for WebApp pentesting.

When pentesting web applications, a MITM proxy to log HTTP(S) requests is a necessity. Although open-source alternatives exist, PortSwigger's BurpSuite is the de-facto standard in …

EFA Departure Monitor on the command line

Fixing WiFi Multicast Flooding in bridged networks

I'm using MPD and PulseAudio's RTP multicasting to get a seamless multi-room audio experience.

Unfortunately, if you're using a network bridge to connect your wired and wireless LAN, using multicast RTP might have unintended consequences: All WiFi clients are flooded with multicast traffic, which can bring down the entire wireless …

Upgrading iLO 4 on a HPE ProLiant MicroServer from Linux

I recently got my hands on a ProLiant MicroServer Gen8 by Hewlett Packard Enterprise (HPE). As I always do when setting up a server I checked if the device needs a firmware upgrade.

Generating syntax diagrams using the LaTeX rail package

If you ever had the need to add syntax specifications to your document, you basically have two options: Either write down the syntax in the Backus-Naur form (BNF) (or one of its derivatives) or opt for a more graphical approach by adding "railroad diagrams". In my opinon, the latter are …

ODROID-C1 issues finally fixed

When I decided to replace my beloved Raspberry Pi media center with something more powerful, I didn't expect so many issues. I purchased Hardkernel's ODROID-C1 and was rather excited. The Kodi Entertainment Center worked much smoother than before (especially since I compiled it to use the Framebuffer instead of X11 …

Working around UEFI madness on a HP ProBook 6465b

It's past 6 o'clock in the morning and - while writing this blog post - I'm wondering why manufacturers seem unable to implement stuff properly. If I had known what pain UEFI would cause me, I would have sticked to my good ol' BIOS boot setup.

But first things first: Since I …

ODROID-C1 post-installation tips

Some weeks ago I decided you replace my old and rusty Raspberry Pi (serving as a media center) with something faster (and less likely to suddenly lose ethernet connection). I stumbled over the dirt-cheap ODROID-C1, which outruns the Raspberry Pi (and even the brand-new Raspberry Pi 2) thanks to its …
