Raspberry Pi Static IP

Raspbian Jessie uses a different network manager than most other Linux systems and previous versions of Raspbian. Most users will have no use for a static IP, but it is necessary in some environments. There is a lot of confusion online, but this method has been tested to work with the newest edition of Raspbian as of August 8th, 2016.
Also please note, depending on what you need a static IP for, it may be easier to go into your router(or other DHCP server) and specify an IP for your device there.

First, open /etc/dhcpcd.conf with your favorite text editor(We'll use nano).
Run the command: sudo nano /etc/dhcpcd.conf

Add this to the end:

interface eth0
static ip_address=192.168.1.7/24
static routers=192.168.1.1
static domain_name_servers=8.8.8.8



Use Ctrl+X to save and exit

Replace ip_address with an IP of your choice, routers with the IP of your router or gateway, and domain_name_server with the IP of a DNS server. If you're on Wi-Fi, change "eth0" to "wlan0". Make sure ip_address fits your network scheme!  You can leave the DNS server set to 8.8.8.8.

About Cayenne Cayenne is an IOT cloud program to assist you in quickly building automated projects with the Raspberry Pi, Arduino, and other boards. You can the easy to use graphical interface to manually control pins, view live sensor data, and set up automated responses to run based on time or events. It also let's you remote control the device in a way similar to a VNC server. Cayenne may no be for everyone though, on some board models the program takes up 100% of the processing power constantly. But not to worry, the program is almost as easy to uninstall as it is to install. This tutorial will walk you through the installation process for Raspbian. Installation Android App Cayenne is best used with the companion Android and iOS apps. After opening the app, it will walk you through logging in (or creating an account) and autonomously locate and install your Pi. After it scans the network, click your Pi and enter the username and password (Default Raspbian Username:

Raspberry Pi: Backup and Restore

While making another tutorial, I realized one thing I forgot that every Pi owner should do regularly: Backup the SD card in case of a crash  So this tutorial will show how to use our favorite operating system, Linux, to clone an SD card to an image file. Prepare First, you will need to find the path of your SD card. One easy way to accomplish this on Ubuntu systems is to open the "Disks" utility by opening the Unity Dash and searching "Disks". Here is another screenshot of the icon on a Ubuntu system running the Cinnamon desktop: Once the window opens, select your device from the left and the device path should be displayed(See highlight below). If you use a different distribution, you may have to use a different method to find the disk path. Different versions of Ubuntu may also call Disk Utility slightly different names. Now we start to backup the SD card! We're going to be using the dd command, which looks like this: sudo dd bs=XM
