Did you break everything? There's no shame in it. My config looks like: /etc/network/interfacesĬtrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev So I just copy over config from another, working, raspberry pi. The authoritative guide on the subject can be found on, and you might just want to do that.Īs for me, I don't know how not to break this stuff. There are like a million posts on how to configure a wifi connection. If you might break it all, you'll want to do it before you invest a lot of time into configuration. I cannot tell you how many times I have lost all ability to connect to my machine (ethernet or otherwise) after messing up the network configuration in an attempt to set up the darn wifi. If you want to connect to your raspberry pi on your wifi network, you'll want configure the connection earlier rather than later. This works a lot like setting your locale highlight your region and TAB to OK. Just highlight the one you want and TAB to OK. The next screen lets you choose your default locale. When you're done, hit OK (skip there by pressing TAB). Personally, I deselect en_GB.UTF-8 UTF-8 and then select en_US.UTF-8 UTF-8. Scroll with your arrow keys (it sucks and takes forever) and press spacebar on the to select / deselect. When you hit the "Change Locale" menu, you'll get a very long list of possible locales. Whatever you do, you want to make sure to hit Localisation Options. Advanced Options -> Expand Filesystem.So that my machine has an informative name on my network. I end up doing a lot of tinkering in here. The default username and password are, of course, pi and raspberry. Once you discover the IP address, ssh in. You won't know the machine's IP address ahead of time, but you can get that info a bunch of different ways (I use iNet Network Scanner). With SSH enabled, you should be able to connect to the pi remotely via ethernet the very first time you boot it up. I'll run through how to set up wifi later in this post. I don't know any tricks here for the time being, you'll need to connect to the pi via ethernet. As far as I know, you need to be able to connect to your pi in order to configure the wifi connection. If you want to connect to your pi via wifi, you've arrived at yet another catch-22 situation. Then a simple touch ssh command will do the trick. I never can remember where my SD card mount lives in the mac filesystem, so I navigate my finder to the mounted SD card and use Go2Shell to put my terminal there. Simply add a blank file, ssh, to the root of the SD card. Luckily, there's a little trick to set up ssh before the first boot. But you also need to connect to it in order to set up ssh. In order to connect to a headless pi, you need to have set up ssh. Ĭonsider the catch-22 situation you're in. I have never been able to remember the syntax to dd, so I just head over to and follow their instructions.Īs for the Raspbian distribution, I choose the latest "lite" version (right now it is "Raspbian Stretch Lite") because I don't use the desktop environment. Since I've done this more than a handful of times, I thought I'd record the steps I take to configure my new machine. The initial setup for a headless raspberry pi can be tricky. The project was to hook up a PiTFT display and use it to show upcoming Manhattan-bound Q trains. I recently set up a fresh Raspberry Pi 3 B+. They all run headless and I SSH into them occasionally to see if anything has broken. At this point, there are three tucked away in different corners of my apartment (one runs an online temperature sensor). I do a lot of projects that involve raspberry pis.
