Proxy App

The host proxy application for TRENTOS running in QEMU. This proxy implements the communication channels to the host machine in order to

• simulate Non Volatile Memory
• access TAP interfaces
• test ChanMux

The inner working mechanism to mux-demux channels is based on ChanMux/HDLC (https://wiki.hensoldt-cyber.systems/display/HEN/SEOS+ChanMUX%2C+Linux+Proxy+App).

Getting Started

The project builds a Linux command line utility

Dependencies

• uart_socket
• seos_sandbox
• TinyFrame

Build steps

create workspace folder

mkdir proxy_app
cd proxy_app

check out into folder "src"

git clone --recursive ssh://[email protected]:7999/hc/mqtt_proxy_demo.git src

run build, will create a folder "build" with the application binary

trentos/build.sh <path-to-OS-SDK>

Synopsis

./proxy_app -c [<connectionType>:<Param>] -t [tap_mode]

Example usage

Run application and connect to QEMU on TCP port 4444, allowing for the creation and usage of TAP devices

build/proxy_app -c TCP:4444 -t 1
