[How-To] Raspberry Pi FreeBSD Web Server

By Leave a Comment

User spacemonkey shows us how to get a FreeBSD web server set up on Raspberry Pi. Follow the link below for the full set of instructions.

0. Introduction


The purpose of this guide is to provide step by step instructions on how to set up a system consisting of a Raspberry Pi credit card-sized computer, running the FreeBSD operating system and the nginx web server. The server is meant to operate “headless” (i.e. without a display or keyboard) and run at relatively low power (approximately 2 to 4 Watts). This guide assumes that the reader has some minimal familiarity with a Linux/Unix/BSD-like environment.

NOTE: Due to Raspberry Pi’s relatively low power CPU, some of the steps described below (e.g. compiling software) will take a few hours. Patience is a virtue :)

Aside from patience, you’ll need the following hardware:

– Raspberry Pi
– Power supply for the Raspberry Pi
– USB keyboard
– Display (with HDMI or Composite video connector)
– SD Card (recommended minimum size 4 GB)
– Ethernet cable
– A BSD or Linux PC with an SD card slot

[How-To] Using a Raspberry Pi as a serial console server for FreeBSD

By Leave a Comment

This short guide by user solence will show you how to set your Raspberry Pi as a serial console server for FreeBSD. Follow the link below for the full set of instructions.

My home server runs FreeBSD 11.0, and, of course, has full disk encryption. This requires a passphrase to be entered while booting, so I need a keyboard and monitor attached, and have to be in the same room for restarts and after power outages. This is not acceptable at all. There is no need for a display and keyboard otherwise, and I want to be able to enter the passphrase remotely, but without compromising security. Luckily, the server has a serial port and I have a spare Raspberry Pi. So I can connect the serial port to the Raspberry Pi, SSH into it and use the serial console of the server just like physical access. Hooray for stuff from the 1960s still being useful!

So first things first, I need to connect the Raspberry Pi to the serial console. Since it only has USB (aside from GPIO), a USB to serial port adapter is necessary. The Raspberry Pi runs FreeBSD 11.0, which has good out-of-the-box support for the Prolific PL2303 chipset, so I just ordered a cheap apdater based on it. It probably works with Linux as well, if you’re using Raspbian. You can use dmesg to check if it was detected correctly:

[How-To] Installing & Updating FreeBSD 11.0 on Raspberry Pi

By 1 Comment

This guide by user  will show you how to install and update FreeBSD 11.0 on a Raspberry Pi machine. Follow the link below for the full set of instructions.

FreeBSD runs great on a Raspberry Pi, but the official images are all stable or current branches and there is no support for binary updates, i.e. freebsd-update. So I tried to figure out how to install the latest release version and keep it updated as well, without starting from scratch with a new image every time.

While it is possible to build a kernel and world on the Raspberry Pi itself, it takes about a week to finish (trust me, I tried) and you need a much larger /tmp on a disk or share for it to work in the first place. Since FreeBSD can also be cross-compiled, I decided to use my Xeon box to do the heavy lifting and then just install it on the Raspberry Pi.

[How-To] ownCloud with RaspberryPi 3 and FreeNAS

By Leave a Comment

In this tutorial, user ro55mo of Level1Tech shows us how to get an ownCloud setup on Raspberry Pi 3, using a FreeNAS system as a data store. Follow the link below for the full set of instructions.

owncloudfreenasThis guide is intended for the installation of OwnCloud on a RaspberryPi 3 with a FreeNAS server as the storage backend.

I am aware this is rather backward as FreeNAS has an OwnCloud plug-in you can install but I wanted to see if it was possible.

Objective

The object is to have the RaspberryPi act as a web front end for the backend storage. Their are guides on doing this with external USB drives but a FreeNAS server with ZFS and RAID struck me as a more sensible storage solution.

The storage must be totally transparent to the user (me). I don’t want to have to rely on the “external” storage module that comes with OwnCloud as these all end up with seperate folders inside your view of OwnCloud. If this was the case and I forgot to upload something to the right folder I could exhaust the 16GG MicroSD card on the RaspberryPi very fast.

As stated elsewhere in the guide my FreeNAS box is not in its “final form” yet. But once it is and I have an offsite backup in place I will replace Dropbox and Google drive with this solution.

[How-To] Reading DHT11 Temp. Sensor on Raspberry Pi FreeBSD

This tutorial by user Alex Samorukov shows us how to get the DHT-11 temperature sensor readings configured on a Raspberry Pi running FreeBSD. Follow the link provided below for the full set of instructions.

Connecting sensor to the RPi

DHT-11 is a very cheap temperature/humidity sensor which is commonly used in the IoT devices. It is not very accurate, so for the accurate measurement i would recommend to use DHT21 instead. Anyway, i had DHT-11 in my tool box, so decided to start with it. DHT-11 using very simple 1 wire protocol – host is turning on chip by sending 18ms low signal to the data output and then reading 40 bytes of data. Details about the protocol could be found in the specification. To read data from the chip it should be connected to the power (5v) and gpio pin. I used pin 2 as VCC, 6 as GND and 11 as GPIO (it is GPIO17, see pinout):

[Blog] FreeBSD Pi

User  details his experience in getting FreeBSD started on the Raspberry Pi. Check out the link below for his findings, including a lengthy discussion from other users in the comments section.Raspberry_Pi_Logo.svg

OpenBSD is in many ways the worlds best security operating system. So much so, in fact, they don’t want to port to the Raspberry Pi. Why? Because the boot loader is a ‘binary blob’ that gets loaded to the GPU where it proceeds to load the rest of the Operating System to regular memory and the regular CPU. It then hangs around as it runs the GPU. It is, theoretically, possible to hack that code so that it became an entry point for things like reading and changing memory. I’m relatively OK with that as it is a highly unlikely target for ‘serious folks’, but they are correct that an exploit could be done that way. (So check the SHA code on any Raspberry Pi boot loader downloads). That is also why I have said “good enough for a home user but don’t bet your company on it or use it if you have TLAs after you”. (Three Letter Agencies…). For that, you want OpenBSD supported hardware. (Cubieboard / Cubietruck are supported IIRC). I’d rather have a UK origin and binary bootloader blob than China sourced and no blob, but that’s just me… not the OpenBSD folks who are Industrial Strength Paranoid (since that is their job, and their day job, and their life, and… OpenBSD is what I would use for any strongly security enhanced system and is the base that China used for their Kylin system). So no OpenBSD on the Pi, but FreeBSD is less obtuse and did make a port.

So I installed FreeBSD.

The install itself is nearly trivial. Go here and download the SD card image:

How-To: FreeBSD on Raspberry Pi 2

By Leave a Comment

raspbsdpiThis short tutorial by user garyhall shows us how to get Raspberry Pi 2 running FreeBSD. Follow the link below for the full instructions.

Most Raspberry Pi’s run some form of Linux (Raspbian, Ubuntu, etc) but you can also run other Unix variants on the Raspberry Pi. Before I started using Linux in the mid 90’s I used FreeBSD – an extremely robust operating system. The good news is that Free BSD for Raspberry Pi is now available and I’ll talk you through how to install it.

First you’ll need to download the images for Raspberry Pi 2 Model B FreeBSD from here or download them from your command line as follows: …

User  shows us how to connect your Raspberry Pi USB to Mac and FreeBSD. A CP2102 serial converter is necessary to do this task. Follow the link below for the short tutorial.

Raspberry-Pi-USB-UART-Cabling

I play with my Raspberry Pi so rarely that I forget how to use my CP2102 serial converter to connect from my iMac or FreeBSD laptop to the Raspberry Pi, so I thought I’d write a blog post and then I’d have an easy place to go back to remember how…
