The project provides a **server (Python)** and clients in **Bash (Linux)** and **PowerShell (Windows)** to support different environments.\n\n\n## ✨ Features\n\n- 🔍 **Evasion**: Random data and domains in each request (`-random`)\n- ⚡ **Flow control**: Adjustable chunk size and sleep interval (`-l`, `-i`)\n- 📂 **File management**: Built-in **upload/download** support\n- 💻 **Cross-platform**: Linux (Bash) and Windows (PowerShell) clients\n- 🐱 **Fully integrated** into Kitsune (https://github.com/JoelGMSec/Kitsune)\n- 🔑 **Privilege escalation support** with `sudo`/`su` in Linux\n- 📜 **Import PowerShell scripts** directly on Windows clients (`import-ps1`)\n\n\n## ⚙️ Requirements\n\n- Python 3 + install requirements.txt\n- Bash + dig + xxd (for Linux client)\n- PowerShell 4.0 (for Windows client)\n\nInstall dependencies:\n\n```bash\npip install -r requirements.txt\n```\n\n\n## 🚀 Usage\n\n```java\npython3 NekoDNS.py -h             \n\n  _   _      _         ____  _   _ ____  \n | \\ | | __ | | __ __ |  _ \\| \\ | / ___| \n |  \\| |/ _ \\ |/ / _ \\| | | |  \\| \\___ \\ \n | |\\  |  __/   \u003c (_) | |_| | |\\  |___) |\n |_| \\_|\\___|_|\\_\\___/|____/|_| \\_|____/ \n                                         \n                                               \n  ----------- by @JoelGMSec -----------\n\n[!] Usage: python3 NekoDNS.py \u003clisten_ip\u003e \u003clisten_port\u003e \u003c-udp/-tcp\u003e\n\n```\n\n**Arguments**:\n- `\u003clisten_ip\u003e` → IP address to listen (0.0.0.0 by default)  \n- `\u003clisten_port\u003e` → Port to listen (53 by default)  \n- `\u003c-udp/-tcp\u003e` → Protocol to use (UDP or TCP)  \n\n**Available Commands**:\n- `upload` → Upload a file from local to remote computer\n- `download` → Download a file from remote to local computer\n- `import-ps1` → Import PowerShell script on Windows hosts\n- `sudo` → Execute with sudo privileges on Linux hosts\n- `clear/cls` → Clear terminal screen\n- `kill` → Kill client connection\n- `exit` → Exit from program\n\n\n## 📸 Screenshots\n\n\u003cimg width=\"1263\" height=\"816\" alt=\"image\" src=\"https://github.com/user-attachments/assets/ab5143a5-04e2-4cc8-8cf9-26ab766493d7\" /\u003e\n\n\n## 🗂️ Documentation\n\nThe detailed guide of use can be found at the following link:\n\nhttps://darkbyte.net/nekodns-jugando-con-dns-una-vez-mas\n\n\n## 📄 License\n\nThis project is licensed under the GNU GPL-3.0 license - See the LICENSE file for more details.\n\n\n## 👨‍💻 Contact\n\nFor more information, you can find me on Twitter as [@JoelGMSec](https://twitter.com/JoelGMSec) \n\nOther ways to contact me on my blog [darkbyte.net](https://darkbyte.net)\n\n\n## ⚠️ Disclaimer\n\nThis software comes with no warranty, exclusively for educational purposes and authorized security audits.\n\nThe author is not responsible for any misuse or damage caused by this software.\n\n# ☕ Support\nSupport my work by buying me a coffee:\n\n[\u003cimg width=250 alt=\"buymeacoffe\" src=\"https://cdn.buymeacoffee.com/buttons/v2/default-blue.png\"\u003e](https://www.buymeacoffee.com/joelgmsec)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjoelgmsec%2Fnekodns","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjoelgmsec%2Fnekodns","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjoelgmsec%2Fnekodns/lists"}
