Milk-V Duo. USB Internet

Milk-V Duo. Access to Internet throw USB RNDIS connection to host machine

This script provide access BETWEEN Milk-V Duo (MilkV) that connected via USB to host device (e.g. RPi 4) AND private/public Network without RJ45 wires, directly just by USB connection

You should run two scripts MilkV-Duo-internet-throw-USB--MilkV.sh and MilkV-Duo-internet-throw-USB--RPi4.sh, for one by each device: this script (MilkV-Duo-internet-throw-USB--MilkV.sh) on MilkV AND (MilkV-Duo-internet-throw-USB--RPi4.sh) on RPi4

• Scheme MilkV <--USB-- RPi4 <--RJ45/WiFi-- Internet --> PC

• Works on Linux Core (MilkV official image https://milkv.io/docs/duo/resources/image-sdk https://github.com/milkv-duo/duo-buildroot-sdk/releases/)

Preconditions This is not requied, but preferably to connect Milk-V Duo to host device by USB Type-C and

Configurating: On Milk-V Duo run script: su root ./MilkV-Duo-internet-throw-USB--MilkV.sh - with autoreboot

On USB host device (e.g. RPi4) run script: MilkV-Duo-internet-throw-USB--RPi4.sh - it`s advisable to reboot after running the scripts.

Testing:

• From USB host device (e.g. RPi4): ssh -p 22 root@192.168.42.1 - test SSH connection sudo iptables -S | grep usb0 -i - list IP / port forwadring

connect via UART interface:

> ls /dev/ttyUSB* > sudo apt-get install minicom > sudo minicom -D /dev/ttyUSB0

• From Internet / Local Network: ssh -p 2222 root@10.0.0.11, where 10.0.0.11 - is USB host device IP address

• From Milk-V Duo: ping 8.8.8.8 -c 2 or wgetcontent=$(wget api.myip.com -q -O -) && echo $wgetcontent

• On Both machines (Milk-V Duo & RPi4): netstat -rn or route - list routing table ifconfig -a - check Network Interfaces & devices & PI & MAC & status ip a show usb0

• How to copy file via SSH to Milc-V Duo: scp test1.txt root@192.168.42.1:~/

TODO:

• Set static MAC address, that will be same after rebooting
• Extract user variable data to bash variables
