One thing I like about the Raspberry Pi is that it’s a small gadget that, once configured, only needs power in order to sit somewhere and do something.\u00a0 For example, BakBoard<\/a> runs on a Raspberry Pi that only plugs into a TV (for both power and display).\u00a0 Unfortunately, in order to get everything running, I typically have ended up connecting various extra wires (network, keyboard, mouse, display) and work directly on the Pi before I can stick it in some random location to do what I want it to do.\u00a0 Below are the steps I figured out so that I can do everything from my main computer and the only wire I need to my Pi is for power.<\/p>\n To get the base image, I went to the Raspberry Pi Downloads Page<\/a> and grabbed the latest Raspbian image (specifically 2017-01-11-raspbian-jessie-lite).\u00a0 Once I had downloaded the zip, I opened it and then doubled clicked the image file (2017-01-11-raspbian-jessie-lite.img).\u00a0 This brought up the Ubuntu image tool and it was easy to “restore” the image to the SD Card.<\/p>\n Since I don’t want to mess with a network cable, I want my Pi to be able to access my wireless network.\u00a0 In order to do so, I modified the interfaces file.\u00a0 It is in the image at etc\/network\/images.\u00a0 Basically I changed the bit:<\/p>\n To be:<\/p>\n Obviously I plugged in the correct network name and password.<\/p>\n The Raspbian OS used to have SSH enabled by default, but last year that changed as a security precaution.\u00a0 The explanation for the change (and where I learned to do what is described below) is described on the Raspberry Pi Blog<\/a>.<\/p>\n Basically, to enable ssh, I just create a file called “ssh” in the boot directory.\u00a0 The contents of boot\/ssh don’t matter–apparently the OS will see that file, enable ssh, and then delete the file.\u00a0 The tricky part was that there were two “boot” directories.\u00a0 There was one at the root of the volume, but there was actually a separate volume as well that is named boot–that’s the one where the ssh file must be created.<\/p>\n The default password to\u00a0 the Raspberry Pi is well-known which is nice because I don’t have to remember yet another password, but also a security risk since everyone knows it.\u00a0 Instead, I like to use key based authentication and disable password authentication for ssh access.\u00a0 Here’s how I did that:<\/p>\n First, I generated my public and private key (that was done a long time ago, and there are plenty of sources on the Internet how to do that).\u00a0 My public key is id_rsa.pub (in the .ssh folder in my home directory) and the private key is id_rsa.\u00a0 That creation was on my main computer.\u00a0 Then, on the Raspberry Pi volume, I created the directory home\/pi\/.ssh.\u00a0 I then copied the public key file (id_rsa.pub) into the home\/pi\/.ssh folder and also copied the file and named the copy “authorized_keys”.<\/p>\n Then, to disable password authentication via SSH I opened up the file etc\/ssh\/sshd_config in a text editor and changed:<\/p>\n To be:<\/p>\n Once the above has been completed, I can stick the SD card into the Raspberry Pi and then plug in the Pi (giving it power).\u00a0 It automatically connects to the wifi and I’m able to SSH into it without a password.\u00a0 There’s nothing new here that can’t be found in various places online, but I’ve gathered the pieces together for my own reference at least.\u00a0 Here are a few “gotchas” I encountered along the way:<\/p>\n Introduction One thing I like about
