This repo contains various scripts to configure for Raspberry Pi. They can also be used with other Linux distributions by making slight changes.

If you want to make your raspberry pi a router or something than you won't have to spent days to make it work. You just have to grab right recipe and put it in correct place and install few basic packages.

First, install dnsmasq because it the backbone of most of the recipes.

sudo apt-get update && sudo apt-get install dnsmasq

List of all recipes with descriptions:

• wifi-to-eth-route.sh — Share Raspberry WiFi with the device on Lan side. Give WiFi access to a Non-WiFi device.

• eth-to-wifi-route.sh — Make it WiFi Router.

• wifi-to-eth-bridge.sh — A layer 3 solution. See #2 for discussion.

Download a recipe to pi user's home directory. For example:

curl -O https://raw.githubusercontent.com/arpitjindal97/raspbian-recipes/master/wifi-to-eth-route.sh

Make the file executable:

sudo chmod 755 wifi-to-eth-route.sh

If using LXDE desktop, edit /home/pi/.config/lxsession/LXDE-pi/autostart:

nano /home/pi/.config/lxsession/LXDE-pi/autostart

And add the last line to start the script automatically after reboot:

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash
@point-rpi
sudo bash /home/pi/wifi-to-eth-route.sh

Without desktop (lite version), edit /etc/rc.local with root privilege:

sudo nano /etc/rc.local

And add the following before exit 0 to start script automatically after reboot:

bash /home/pi/wifi-to-eth-route.sh

Be sure to give full path to the file.
That's it! Reboot to see the changes.

sudo reboot

There are few things which can't be automated and has to be done manually. Below are some tips to help you get stuff done.

If the script which you are using ahs dnsmasq section, there you will server property. This property is set to Adguard DNS server i.e. 176.103.130.130. So, by default your content will come out as Ads free. You can change to any other DNS server also according to you needs.

When you have written the Image file on to the SD Card. Mount the boot partition and create a file named ssh. Eject the card. Start the Raspberry Pi. You will be able to have SSH connection to it. After boot the /boot/ssh file gets deleted automatically. So, type this to start ssh service on every boot.

sudo systemctl enable ssh

Connect to RPi through SSH by providing it Ethernet. If you don't any Lan cable lying around than plug the SD card into PC. Mount the second partition of the SD Card.

WiFi connections are stored at /etc/wpa_supplicant/wpa_supplicant.conf. Edit this file with root privilege:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

It should look like this after filling network details:

country=GB
ctrl_interface=/var/run/wpa_supplicant
update_config=1
network={
    ssid="Home WiFi"
    psk="password_goes_here"
}

Configuration for eap should look like this:

network={
        ssid="SSID_NAME"
        key_mgmt=WPA-EAP
        password="PASSWORD"
        eap=PEAP
        identity="USERNAME"
}

Suggestions and PRs are welcome to make these recipes more useful.
