Raspi-Mobile is designed to run as a '''Mobile Device''' together with your '''Tablet''' or '''Laptop''', prepared for conditions such as in a Train, Flight, Hotel and so on.<br>
The project has its focus to run as a '''Streaming Server''' next to common features like '''Wireless''' and '''Internet-Routing''' support.<br>
<br>Two major Raspberry/Linux issues are solved:<br>
*'''True automatic mounting of USB flush drives'''
**Plugin any USB sticks, supporting the filesystems ntfs, vfat and exfat
*'''Graceful shutdown'''
**This solves the issue of preventing disk damages in case of losing electricity power.
**No need to login or connecting a keyboard and monitor to shutdown, just plugin the '''shutdown usb device''' to initiate a graceful shutdown

Intro

Raspi-Mobile is designed to run as a Mobile Device together with your Tablet or Laptop, prepared for conditions such as in a Train, Flight, Hotel and so on.
The project has its focus to run as a Streaming Server next to common features like Wireless and Internet-Routing support.

Two major Raspberry/Linux issues are solved:

  • True automatic mounting of USB flush drives
    • Plugin any USB sticks, supporting the filesystems ntfs, vfat and exfat
  • Graceful shutdown
    • This solves the issue of preventing disk damages in case of losing electricity power.
    • No need to login or connecting a keyboard and monitor to shutdown, just plugin the shutdown usb device to initiate a graceful shutdown

Features

  • Support Raspberry3 or Raspberry4. The project was developed with Raspberry4 on Debian Buster
  • Slim image file download, the image size is less than 2GB
  • Easy to setup
  • Automatic mounting and un-mounting USB flash drives
    • Supported file systems: ntfs,ext32 and vfat

  • Support OpenVPN
  • Support of common protocols for streaming:
    • SMB/CIFS
    • WebDav
    • SFTP
    • HTTP

Easy Installation

  • Get the 2GB image here
  • Write the image to a Micro SD Card with the size of equal or better greater than 2GB
    • To write the Image you may use tools like DiskImager
  • Insert the Micro SD Card to your Raspberry and start it
    • If the Micro SD Card is greater then 2GB then login ssh, become root and run raspi-config, goto advanced and then expand filesystem, finish and reboot
  • Installation finished

Default Username and Password

  • Username pi
  • Password raspberry

Hostname and Aliases

Available ONLY when connected through WiFi

  • Hostname raspberrypi
  • Aliases
    • raspi
    • raspberry
  • IP (alias to eth0, works even if eth0 is disconnected)
    • 192.168.5.1

SSH

ssh pi@raspi
ssh pi@192.168.5.1
  • Become root
sudo -i

Wireless default access

  • WiFi SID
    • Raspi-Mobile
  • WiFi Passwd
    • raspberry
  • RaspAP Web-Interface
http://raspi:8080 
http://192.168.5.1:8080

Change password for the pi user

Connect using SSH

Change the Linux Password

ssh pi@raspi

OR 

ssh usernanme@raspi
  • Type
