Recovering versioned files from Owncloud’s data directory
Tasked with recovering files you don’t have access to through the web interface, you can always find these through the file system if you’re the operator. You could, of course, give yourself access, but let’s save that for another time. Right now we want the files our users removed and/or can’t find. We start by […]
Who deleted the files from the Windows file server?
Classic whodunit – the file is gone. Who deleted it? Well, unless you’ve already prepared for this, Windows has no log for you. Sorry. The good news is that this is an excellent time to prepare for the next time. So let’s do that. Enable the auditing of file operations to the Windows Event Log […]
ClipWriter, a PowerShell script that emulates keyboard input to transfer files and text
I wrote this tool today, as I was annoyed having to do a bunch of changes to a configuration file on a client site through a restrictive remote tool that doesn’t let you paste or transfer any files for “security reasons” (read: BOFH) It pastes text, files and entire directory structures by simulating keyboard input.

Enable remote management of Windows Server Core and Hyper-V Core
This is a reference for the commands to enable the firewall rules necessary to remotely manage Windows Server Core and Hyper-V Core. I keep having to look these up… Enable-NetFireWallRule -DisplayName “Windows Management Instrumentation (DCOM-In)” Enable-NetFireWallRule -DisplayGroup “Remote Event Log Management” Enable-NetFireWallRule -DisplayGroup “Remote Service Management” Enable-NetFireWallRule -DisplayGroup “Remote Volume Management” Enable-NetFireWallRule -DisplayGroup “Remote Scheduled […]
Forcing Cygwin to create sane permissions on Windows
If you use Cygwin to mainly manipulate files in your regular Windows filesystem, under /cygdrive/…, you have probably seen this message more than a few times: “The permissions on <node> are incorrectly ordered, which may cause some entries to be ineffective” You have also likely seen “NULL SID” as the top entry in permission lists. […]
Property ‘BindToHostTpm’ does not exist in class ‘Msvm_SecuritySettingData’
Microsoft has apparently messed up their integration of the Hyper-V Manager on Windows 10 with Hyper-V Server hosts, resulting in the above error message showing up on the “Security” tab of virtual machines. So now what do you do if you want to disable Secure Boot to load some Linux distribution that doesn’t support it? […]
Script for creating a compressed image file from a Raspbian SD card
I’ve previously presented a manual process for doing this, but lately I’ve had to do it more often, and I figured it was about time for automation. This script will: Run e2fsck on the root file system Erase logfiles, such as bash_history and stuff in /var/log Erase the test.h264 video file Wipe resolv.conf Defragment the […]
Using external Certificate Authority certificates in a restricted or closed environment
In this example, we’ll be using a wildcard certificate from Let’s Encrypt, obtained through their recently released wildcard certificate offering. What we’re doing The use case is that we want, for one reason or another, to use this certificate in an environment that does not have unrestricted internet access, such as a health institution or […]
My tweaks to get Kali Linux running well on the GPD Pocket
Mostly notes to myself, but hey, maybe it helps you too! Get Kali for the GPD Pocket I installed using re4son’s modified image from here. Removing the GRUB splash screen (it’s sideways anyway, which looks horrible, and I’m not multibooting) /etc/default/grub GRUB_TIMEOUT=0 GRUB_BACKGROUND=”” Speeding up WiFi so it doesn’t lag if you SSH into the […]
