Raspberry Pi 3 Hotspot Install

This is an install script to prepare a raspbian-lite image and configure your Raspberry Pi 3 as a hotspot.

1. Download latest raspbian lite

$ wget https://downloads.raspberrypi.org/raspbian_lite_latest

$ unzip raspbian_lite_latest

2. Flash sdcard

Check what volume /dev/sdX is already mounted and used

$ df -h

if your sdcard is mounted

$ sudo umount /dev/sdX

Format and copy raspbian-*-lite.img to sdcard

$ sudo dd if=/dev/zero of=/dev/sdX bs=1M count=8
$ sudo dd bs=4M if=*raspbian-*-lite.img of=/dev/sdX

3. Mount sdcard on ./root

$ sudo mount -v -o offset=70254592 -t ext4 /dev/sdX ./root

If offset does not match, you can get it with this command :

$ sudo fdisk -l /dev/sdX

It should return something like that :

Device     Boot  Start     End Sectors  Size Id Type
/dev/sdX1         8192  137215  129024   63M  c W95 FAT32 (LBA)
/dev/sdX2       137216 2709503 2572288  1,2G 83 Linux

So offset=512*137216.

4. Config SSID and password

Edit SSID and password in config/hostapd.conf

Optionally you may also edit IPs in config/interfaces and config/dnsmasq.conf

5. Config openvpn

Put your openvpn server conf in config/openvpn-server.conf

Put your username and password in config/openvpn-server.auth

6. Run script

$ sh start.sh

To re-mapping the keyboard give the two letter code for your country as argument :

$ sh start.sh fr

Unmount sdcard

$ sudo umount ./root
