rou2exOS Rusted Edition is an innovative operating system that represents the second iteration of the RoureXOS project, completely rewritten in Rust for improved performance and safety. This DOS-like hobby OS is designed for enthusiasts and developers interested in exploring alternative operating systems.

For further insights into its development, refer to the following resources:

• Original RoureXOS
• rou2exOS Rusted Edition Overview

Key Features

• Runs on an ISO image, compatible with the QEMU emulator.
• Successfully tested on x86_64 bare metal, booting from a USB flash disk.

Building and Running the OS

The following commands illustrate how to build and run the operating system:

# Install Rust and its dependencies
make init

# Ensure required tools are installed on a Linux system
sudo dnf install xorriso net-tools grub2-tools qemu qemu-common qemu-system-x86

# Compile the kernel and bootloader, and create an ISO image
make build

# Run the QEMU emulator with the ISO image
make run_iso
make run_iso_floppy

# (Alternative) Run the kernel exclusively
cargo bootimage
make run

Testing ICMP/SLIP

To test ICMP/SLIP functionality, execute the following steps:

1. Run the kernel in QEMU to retrieve the pty number from the output:

   make run
   

   This will show the character device location, for example:

   char device redirected to /dev/pts/3 (label serial0)
   

2. Create the sl0 interface for SLIP packets:

   sudo slattach -L -p slip -s 115200 /dev/pts/3
   sudo ifconfig sl0 192.168.3.1 pointopoint 192.168.3.2 up
   

3. Use tcpdump to monitor packets on the sl0 interface:

   sudo tcpdump -i sl0
   

This project is ideal for those with an interest in operating systems and low-level programming, offering a hands-on approach to learning and experimentation.
