I'm new to raspberry pi's and Linux in general. I'm setting up some Pi's to access a webpage. I have tried using:
nano /home/pi/.config/lxsessions/LXDE-pi/autostart
then adding the line
#chromium-browser www.etc.com
but what I found is that while it auto starts chromium, it boots into openbox and the ethernet interface is disabled. I made sure to add
sudo nano /etc/network/interfaces and iface eth0 inet dhcp, but when I reboot again it changes nothing.
So my main question is how do I either make this same thing boot into the desktop AND open chromium, or have chromium startup auto AFTER boot up and log in.
I appreciate any insights and/or help with this.
You can run this alongside the GUI using the method below. I had the same issue and this was the only suggested method that worked.
sudo nano /etc/xdg/autostart/myapp.desktop
(Replace myapp with the desired file name)
Then add this to the file:
[Desktop Entry]
Exec=chromium-browser https://stackoverflow.com

I can't open the GitHub website on any browser and it was running before
I'm not using any proxy server.
when I'm trying to open it in the browser or connect via terminal cloning or any communication with that website it gives me an error.
using MacBook(macOS Big Sur).
The problem has been Solved by changing my IP For Github
192.30.253.112 this was my Ip Adress For Githup befor I change it to
140.82.112.4
in /etc/hosts file by terminal
after the change I cleared the cache memory by command:
sudo dscacheutil -flushcache;
sudo killall -HUP mDNSResponder
Then It opens ^_^.
We set up a voice kit using Raspberry Pi (using "the MagPi essentials AIY Projects" manual). We are able to enable Google Assistant using the command "src/assistant_library_demo.py" in the dev terminal, after Raspberry Pi starts up. We would like to embed the voice kit in a stuffed animal with a portable power supply (i.e., used to charge cell phone on the go). But when the portable power supply is charged, the Raspberry Pi resets. That requires us to go back into the Raspberry Pi, open the dev terminal, and run the Google Assistant file.
My question: Is it possible to run a startup script that automatically runs Google Assistant upon Raspberry Pi starting up? How to do this?
I ended up creating a crontab job after a 10 second wait. Starting right at boot didn't give it enough time for the internet to connect fully.
In terminal type:
crontab -e
Choose an option if it asks how you want to open/edit the file. Then at the bottom put:
#reboot sleep 10 && /home/pi/pathtofile > /home/pi/cronlog 2>&1
Save the file and reboot or pull the cable out and plug it back in. The cronlog helped me troubleshoot this whole process and get feedback on why it didn't work.
Take a look at this page. It tells you how to set up a service which will run automatically.
If the link has gone bad, here is a short explanation of it:
Create a file called my_assistant.service in the src directory, and put in the following code
[Unit]
Description=My awesome assistant app
[Service]
Environment=XDG_RUNTIME_DIR=/run/user/1000
ExecStart=/bin/bash -c 'python3 -u src/my_assistant.py'
WorkingDirectory=/home/pi/AIY-projects-python
Restart=always
User=pi
[Install]
WantedBy=multi-user.target
Where the file says src/my_assistant.py, replace my_assistant with your program's filename. Now go to the folder that file the .sevice file is in, and run the command sudo mv my_assistant.service /lib/systemd/system/. This code moves the file to the services folder. Now you can run the following commands to change the service:
Enable the service- sudo systemctl enable my_assistant.service
Disable it- sudo systemctl disable my_assistant.service
Start it (just runs it once, enabling makes it run on startup)- sudo service my_assistant start
Stop it- sudo service my_assistant stop
See the logs, when the program was started and if an error occurred- sudo service my_assistant status
I have built the linux system for my RPi3 using buildroot. It boots properly and I can access the wired connection properly. However, I am stuck with enabling the wlan.
Here is what I have done so far.
Built the filesystem using buildroot:
make raspberrypi3_defconfig
make
After booting linux successfully I followed this link to enable wlan.
As the author of the post mentions, I had to select some of the wireless related packages by running make linux-menuconfig. But when I did run it, these packages were already selected.
I then ran make menuconfig and selected wpa_supplicant and other packages.
Now, when I boot the RPi3, wlan0 is not listed when I run ifconfig -a. I googled it a bit and found that there should be folder named wlan0 under /sys/class/net/. But I can only find eth0 and lo
Kindly guide me on how to get the wlan working. dmesg log is posted here
If you are using Buildroot, make sure you have selected BR2_PACKAGE_RPI_WIFI_FIRMWARE.
Also you have to manual load the wifi kernel module:
# modprobe brcmfmac
After that, you can confirm wlan0 with
# ifconfig -a
You could also configure Buildroot to build udev as /dev management option, in this case, WiFi kernel module will be loaded automatically.
I am trying to configure LIRC to work with my Raspberry 2B and a circuit I build with a transistor and a IR transmitter as explained in this tutorial
After the installation of LIRC, I followed all the steps and I added these two lines in /etc/modules
lirc_dev
lirc_rpi gpio_out_pin=36
Then I typed this in /etc/lirc/hardware.conf
LIRCD_ARGS="--uinput"
LOAD_MODULES=true
DRIVER="default"
DEVICE="/dev/lirc0"
MODULES="lirc_rpi"
LIRCD_CONF=""
LIRCMD_CONF=""
After rebooting, I added the configuration of my Samsung remote (BN59-00516A) to /etc/lirc/lircd.conf
Then I restarted LIRC again but when I run a command to send a IR frequency
irsend SEND_ONCE Samsung_BN59-00865A KEY_POWER
it complains with the following error:
irsend: could not connect to socket
irsend: No such file or directory
I am guessing this is a problem with my device socket, because in the hardware.conf file I set
DEVICE = "/dev/lirc0"
(just because the tutorial states it), but lirc0 file isn't within the folder.
I couldn't find any other question related to this problem and google didn't help me much either. Does anyone have any hint on this?
After googling a lot, I found out an update is needed to have everything working properly. In my case I did:
apt-get update, apt-get upgrade, rpi-update
Also, as pointed out in this other tutorial, depending on the Raspberry firmware, you might need to add this to /boot/config.txt
dtoverlay=lirc-rpi,gpio_in_pin=XX,gpio_out_pin=YY
Substitute X and Y for whatever pins you're using!
I had a similar problem and I solved it with this command:
sudo lircd --device /dev/lirc0
If you set the value of LIRCD_ARGS in /etc/lirc/hardware.conf to "--device /dev/lirc0", it should start lircd appropriately, when /etc/init.d/lirc is started at boot.
you need to run lircd. It will create two files (lircd and lircd.pid) at /var/run/lirc/:
lircd
I got the same error messages. But had all configurations done. The restart of the lirc daemon solved this issue by typing
$ sudo /etc/init.d/lirc restart
I think is useful to say that the gpio_in_pin=XX,gpio_out_pin=YY part of the /etc/modules can be double checked with
dmesg | grep lirc
which results in something like
[ 3.437499] lirc_dev: IR Remote Control driver registered, major 244
[ 5.472916] lirc_rpi: module is from the staging directory, the quality is unknown, you have been warned.
[ 6.621156] lirc_rpi: auto-detected active high receiver on GPIO pin 22
[ 6.622515] lirc_rpi lirc_rpi: lirc_dev: driver lirc_rpi registered at minor = 0
[ 6.622528] lirc_rpi: driver registered!
for /etc/modules containing
lirc_dev
lirc_rpi gpio_in_pin=23 gpio_out_pin=22
I have a Pi that runs hostapd and dhcpd on arch linux to create it's own land with the Pi's (routers) IP being 10.0.0.1. This uses the wlan0 interface and it only serves as a standalone router running a web server.
Once I connect to the Pi, I use 10.0.0.1 to display the web pages, but I want to use a hostname such as firepi. I have tried using dnsmasq, but I haven't been successful. Any help would be greatly appreciated especially if you can give me some detailed examples as I am a novice.
The purpose of this system is that I have created a web app that you can use to ignite fireworks over WiFi at a safe distance. I would just like the convenience of using a hostname instead of the IP address.
I must add that I will more than likely be using an iPhone to connect to the server, should this affect anything.
Not too sure how or why but this is what I did and it is successfully working now, so this is just for future users who may need a similar setup to mine.
First I installed hostapd and dhcpd and made sure they were working. Next I changed '/etc/hostname' to firepi and the '/etc/hosts' and added '10.0.0.1 firepi'. Then I installed dnsmasq, and set the interface to wlan0, and finally added '10.0.0.1 firepi' to '/etc/resolv.conf'.
After a full reboot, I joined the network on my iPhone, navigated to firepi and sure enough, it worked!
Thanks to the other users for their advice and tips.
You can use avahi on Arch as well to resolve your hostname:
sudo pacman -S avahi nss-mdns
Start the avahi daemon:
sudo systemctl enable avahi-daemon.service
sudo systemctl start avahi-daemon.service
Edit /etc/nsswitch.conf
sudo vim /etc/nsswitch.conf
Change the line:
hosts: files myhostname dns
to
hosts: files myhostname mdns_minimal [NOTFOUND=return] dns
Reboot
Note: don't forget to add .local to your hostname.

http://blog.pixxis.be/post/77285636682/resolve-hostname-with-arch-linux-on-a-raspberry-pi
If you just want to be able to use "firepi" as hostname to connect to it, you can simply add it to your /etc/hosts file using the syntax "IP host".
To make it as easy as possible, run this command as root:
echo "10.0.0.1 firepi" >> /etc/hosts
That'll do the trick.
Can you try avahi ?
sudo apt-get install avahi-daemon and
sudo apt-get install avahi-browse
I've successfully used that on Raspian. Unless you change the hostname using
sudo raspi-config you will access via raspberrypi.local
Note that if you plan to access the RPi from Windows you will need to install Bonjour Service first(if you have iTunes intalled, you might have those, run services.msc and check if the Bonjour Service is started)
Another note: On a friend's iphone I've installed a generic vnc client and had x11vnc running on the RPi and succesfully managed to connect to the RPi (since avahi-daemon was installed)
