A simple multithreaded IP and port scanner built in Python. This tool checks whether hosts in a given IP range are online using TCP SYN scans and scans for open ports on reachable hosts.
- IP Range Scanning: Scans a specified range of IP addresses to check if hosts are online.
- Port Scanning: Scans commonly used ports (e.g., HTTP, HTTPS, SSH) on reachable hosts.
- Multithreaded: Performs scans concurrently, speeding up the process.
- No Root Privileges Required: The tool uses TCP SYN scans instead of ICMP ping, so it doesn't require administrator or root privileges.
- Python 3.x
- No external dependencies
-
Clone the repository or download the Python script.
-
Run the script by providing the range of IP addresses you want to scan.
-
Open a terminal and navigate to the folder where the script is saved.
-
Run the following command:
python3 your_script_name.py
-
The script will scan IP addresses from
192.168.1.1to192.168.1.10by default. You can modify the range in the script or adjust it as needed.
To change the IP range to scan, modify the following lines in the Python script:
start_ip = "192.168.1.1"
end_ip = "192.168.1.10"Change the start_ip and end_ip values to the desired range of IP addresses.
To scan a different set of ports, modify the ports list inside the scan_ports function:
def scan_ports(ip, ports=[80, 443, 22, 8080]):You can add or remove ports from this list to scan specific services.
-
TCP SYN Scan: The tool checks if hosts are online by attempting to establish a TCP connection to port 80 (HTTP). If the connection is successful, the host is considered reachable.
-
Port Scanning: After determining if a host is online, the tool attempts to connect to commonly used ports (e.g., 80, 443, 22, 8080) to check if they are open.
-
Multithreading: The tool scans multiple IP addresses concurrently, reducing the overall scanning time.
