If the address is unknown, Device A broadcasts an ARP request asking, "Who has this IP address?"
| Issue | Probable Cause | Solution | |-------|----------------|----------| | Permission denied | Lack of root access | Root your device or use tools that work without root (scanning only). | | arpspoof: command not found | Binary not compiled or executable | Run gcc in the jni folder to compile, or use precompiled binaries from /libs . | | Scapy cannot send packets | Python permissions issue | Run the script with sudo or ensure your user has necessary capabilities. | | Network not detected | Interface name incorrect | Use ifconfig to check the correct interface (e.g., wlan0 , eth0 ). | | Target stays online | IP forwarding enabled | Disable forwarding to cause disconnection, or ensure spoofing is active on both target and gateway. |
The attacker sends forged ARP responses to the target device, claiming that the attacker’s MAC address belongs to the network router. Netcut Termux

Netcut is a network management tool that allows users to control network connections. It can be used to cut off or limit the internet access of specific devices connected to your network. Typically, Netcut works by sending ARP (Address Resolution Protocol) spoofing packets to the router, making it appear as if the device's MAC (Media Access Control) address has changed, effectively cutting off its internet connection.
Netcut is a network control utility that allows users to cut off network connections for specific devices on a network. When integrated with Termux, Netcut becomes a potent tool for network management, offering functionalities such as: If the address is unknown, Device A broadcasts
