Ssh that worked, you will be logged into your target machine without having to enter a password. If all of this worked, you should be able to log into the target machine with “ssh” from the “Again, “scott” is my username on the remote system and “mondo” is the name of the system we want to shutdown: Ssh-copy-id -i~/.ssh/id_rsa.pub will be prompted for your password on the target machine after the command above is entered and this is so that the key can be registered there. In my example, “scott” is the name of my account on the target node that has sudo privilege and “mondo” is the name of that machine: Default all the entry prompts:Ĭopy the generated key over to the machine that you want to perform the automated remote shutdown. Now exit back to the shell without sudo privilege:Ĭreate an ssh key for automatic password entry for ssh login (This is very secure). You are still logged into the Raspberry Pi but we need to log into the www-data account now:Ĭreate an ssh hidden folder for an “ssh key” to facilitate automatic login without manual password entry:Ĭhange ownership for the. To do this “sudo nano /etc/passwd” and find the www-data account and change it to the following: You still won’t be able to easily log into the account without changing the /etc/passwd record to include shell access. ![]() The Apache web server runs under the user account “On a private LAN, like a home network, as long as the Raspberry Pi has no connection route from the public internet and you have secured your router and wireless access, the risk is manageable.Ĭhange the password for www-data so that you can log into the “apache” web server account: Sudo nano /var/Now that we have the script, we will be executing the script from a web browser on your local LAN that points to the address of the Raspberry Pi and the script we just created. ![]() Also, “mondo” in my example is the target computer that we want to develop the shutdown procedure for. In my example, “scott” is an account with sudo privilege to perform the following steps. On your Raspberry Pi, from a command Window:Īdd the following to the end of /etc/apache2/nf Note that the Raspberry Pi and the target computer must be on the same LAN for this to work. This computer could be a windows machine with modification to the following procedure. The script runs from a web page hosted on the Raspberry Pi and issues a “sudo shutdown -P 0” to the target linux computer. ![]() The company also debuted new white-box Alexa original design manufacturer (ODM) hardware: Calix’s GigaSpire Max and Gemtek’s Vita.This piston is designed to execute an orderly system shutdown of an Ubuntu computer from Alexa which toggles a virtual switch which in turn executes an HTTP GET request to a Raspberry Pi running a CGI Script. Developers don’t need to build their own voice user interface - instead, they simply provide music metadata to Amazon on a “regular basis,” and Amazon takes care of updating the voice models in the background.Īnd in mid-October Amazon launched a public beta of Alexa Presentation Language (APL) - a suite of tools to help developers create “visually rich” skills for Alexa devices with screens, such as Amazon’s Echo Show, Fire TV, Fire Tablet, and Echo Spot. In related news, Amazon debuted the Music Skill API last month, which allows developers to stream songs from online services to Alexa devices and Amazon Echo speakers. Wake-on-Lan Controller follows hot on the heels of the Alexa for PC app, which became broadly available to Windows 10 users in the U.S., U.K., and Germany last week, and New Release Notifications, which lets users follow artists and receive notifications when new songs or records become available on Amazon Music. ![]()
