BYOPM is a portable Password Manager implementation based on VaultWarden, an unofficial implementation of BitWarden and a Raspberry PI Zero. It’s a self hosted solution, with full functionality, which is activated by just plugging the device on your computer. Bitwarden’s Official browser addons and extensions are also supported, and the device has been tested both on Windows (10 and 11) and Linux (Debian Based).
This is how to enable Home Assistant’s SMS Integration Service using the Geetech Arduino GPRS Shield (based on the SIMCom SIM900 module) on a Raspberry PI 4 over serial communication. The host system is using Home Assistant Supervised which was deployed in docker.
Due to the fact that Hypervisors stand between hardware and software, they sometimes disrupt the proper communication between the two causing the software to fail. One such case is when software is locked on specific hardware, for example Microsoft Windows Server ROK.
If you follow the default procedure and install the OS directly on the server then everything runs fine without any issues. But what happens when you want to install the OS as a Virtual Machine on the same server? Well if you are using oVirt as your virtualization solution then you get the following message:
Every operating system, has a way to mount file systems from devices or image files and include them in the file system. Under Linux the mount command instructs the operating system for an existing file system and associates it with a particular mount directory. Using the offset parameter of the mount command it’s possible to mount a Raspberry PI image to a directory and interact with it.
Thin Clients, are computers which are optimized to establish a remote connection to a server and run using the remote resources. Usually those systems are not meant to be used for intensive tasks or gaming and they are mostly found in office environments. In the following guide you will find out how to use a Raspberry PI to connect to a local Windows Computer using Microsoft’s RDP Protocol.
Every version of Microsoft Windows following the release of Windows XP includes a Remote Desktop Connection (RDC) client (mstsc.exe). The Remote Desktop Connection is accomplished through the Client using the Remote Desktop Protocol a proprietary Microsoft Protocol which provides a graphical interface to connect to another computer.
48-bit MAC "addresses" are the most commonly used Ethernet interface identifiers. Those that are globally unique are also called EUI-48 identifiers. An EUI-48 is structured into an initial 3-octet OUI and an additional 3 octets assigned by the OUI holder or into a larger initial prefix assigned to an organization and a shorter sequence of additional bits so as to add up to 48 bits in total.
Here you can find a complete list of the registered OUIs from IEEE and here the Wireshark OUI Lookup tool.
How many times you wanted to know if an Ethernet plug or port has internet connectivity and you had to bring your laptop or a cable from the next room to check? And how many times the only tools available were the simple Network Cable tester and your provider’s Modem or Router? For me that was a common issue and of course there was no easy, "plug and play" solution (at a reasonable price!!). Taking these into consideration I decided to give a solution by making a simple optimization to the most common Network tool. Arduino Network Tester, extends the functionality of the well-known Network Cable tester by adding DHCP, DNS and Internet connectivity tests using an Arduino Pro Mini and a W5500 Ethernet Shield with an overall cost of less than €15!
There are many tutorials explaining how to set up your Raspberry PI as a Serial Device. Almost all of those tutorials explain how to setup your Raspberry as a Serial Console, which will act similar to a SSH connection. The current tutorial takes a different approach. You will find out how to turn your Raspi to a Serial USB Gadget, and how to control what you redirect to the Gadget’s Serial port in order to be available to the machine it will connect to. Using socat, commands we will redirect Serial data received over IP to the Gadget Serial port or data from the on-board UART protocol to the Gadget port.
