Warning

This is a PhD project, and it is still very WIP.

RetOS

A Router Network Operating System. RetOS comes from retis which mean network in Latin.

Note

This Operating System is based on the great Writing an OS in Rust from @phil-opp.

How to use

Development

Important

You will need QEMU x86_64 in order to run project in development mode

• Download for Linux
• Download for MacOS
• Download for Windows
• Install with Nix

You can check the command is available by running

qemu-system-x86_64 --version

Run the project with QEMU

cargo run

Note

If further toolchain installation is needed, rust-toolchain.toml depicts what's needed.

Production

By running the following command, you will build the OS images and the executables that will use QEMU.

cargo build --release

Burn to hard drive/USB stick

1. Get the image path

Build the OS and find the image file you want to use (BIOS or UEFI), you can do it like so:

cargo build --release
find ./target/release -maxdepth 1 -name "*.img"

2. Find the hard drive/USB stick

You can find it by using the lsblk command. A possible selection for your device can be like /dev/sda1.

3. Burn the image

Now you have to burn the image on the hard drive/USB stick with the following command:

dd if=<IMAGE_PATH> of=<DEVICE> bs=1M && sync

4. Run it live!

You can directly plug your device onto the PC and boot it :)

Note

If you are using the BIOS image, you may want to enable CMS
