Enable BitLocker Without A TPM Chip (Password-Based Authentication)

Posted on by Brody Rethy
  1. Open Edit group policy.
  2. Navigate to the following directory:
    • Computer Configuration -> Administrative templates -> Windows Components -> BitLocker Drive Encryption -> Operating System Drives
  3. Open/configure the following setting: Require additional authentication at startup. Note, do not open the one named Require additional authentication at startup (Windows Server 2008 and Windows Vista) unless you are using Windows Server 2008 or Vista.
  4. Change the option from Not Configured to Enabled.

If you try encrypting your OS drive without a TPM chip, you’ll now notice you have the option to setup a password or use a drive as a passkey as well.

How To Do IRC Idling Properly

Posted on by Brody Rethy

Requirements

  1. An Internet connected server.
    • This can be a VPS or a on-prem. server you control that’s accessable from the Internet. You could do something on your LAN as well, but that’s up to you.
  2. Knowledge of IRC.
  3. Knowledge of tmux session attaching/detaching. You can read my quick article about it here: Persistent SSH Sessions Using tmux.

Steps

  1. Open or attach to a tmux session.
  2. Install weechat or irssi (recommended), depending on your preference.
  3. Open irssi.
  4. Connect to the server you want to join. Example: /connect irc.libera.chat.
  5. Join the channel. Example: /join #blastwave.
  6. Detach from the tmux session and go about your day. Then, come back whenever and reattach.

Accessing QEMU/KVM From An Android Device Over SSH/SPICE Server

Posted on by Brody Rethy

Assuming you have QEMU/KVM setup, you can access your VMs from your Android phone. This is thanks to the SPICE protocol already being enabled by default in (virt-manager created) VMs. It’s pretty simple if you already have your virt-manager + QEMU/KVM environment setup.

  1. Install the aSPICE Free app from the Google Play Store
  2. Open the aSPICE Free app
  3. Create a new connection by pressing the icon next to the Search Connections search bar. It’s a computer monitor with a plus symbol. It looks like this: [+].
  4. Input your server credentials, and be sure to switch the Connection Type from SPICE to SPICE over SSH.
    • Each individual connection shortcut you save is an individual VM. The way SPICE works is by hosting a VM video stream on an iterating port. Usually they start on 5900, then go 5901, and so on for every new VM started. These numbers are freed up and moved around when VMs are turned off, so be aware of changing connection details depending on if your VM was restarted or not.
