Termux — Netcut
echo 1 > /proc/sys/net/ipv4/ip_forward
A) Discover all devices and list MACs:
nmap -sn 192.168.1.0/24
arp -a
B) Identify suspicious device by vendor:
arp-scan --localnet | awk 'print $2, $3' # IP and MAC
# Use OUI lookup online or "macchanger --list" on Linux distro to map vendor
C) Temporarily block a device (intrusive — for testing only) Netcut Termux
No official Netcut binary exists for Termux. However, Termux on Android can replicate Netcut-like functions using standard Linux networking tools (arp-scan, nmap, ettercap, arpspoof, bettercap) and packet forwarding/iptables rules. Root access (or elevated permissions via Android’s VPN APIs for non-root) is typically required for active ARP spoofing.
Netcut is a Windows tool that can:
❌ Netcut itself does NOT run on Termux (Android Linux environment).
✅ But you can replicate its core functions using command-line tools. B) Identify suspicious device by vendor: arp-scan --localnet
Netcut is a popular Windows/Android application traditionally used to disconnect devices from a Local Area Network (LAN) via ARP (Address Resolution Protocol) spoofing. Termux, a terminal emulator for Android, provides a Linux environment capable of installing network auditing tools. However, due to Android kernel restrictions (lack of raw sockets without root), a direct, one-click port of Netcut does not function natively on non-rooted Termux.
This report outlines the limitations, workarounds (root/compilation), and specific command syntax required to replicate Netcut’s functionality within Termux.
If you prefer a manual approach without third-party scripts, you can use arpspoof (part of the dsniff suite) if your device is rooted. C) Temporarily block a device (intrusive — for
Combine ARP spoofing with tcpdump and wireshark (via Termux’s X11 or save to .pcap):
tcpdump -i wlan0 -w capture.pcap

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:
