Python实现TCP/IP网络扫描的指南

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

sock.settimeout(1)

def scan_port(ip_address, port):
    try:
        sock.connect((ip_address, port))
        print(f"Port {port} is open on {ip_address}")
    except socket.error:
        pass

def scan_ports(ip_address, start_port, end_port):
    for port in range(start_port, end_port+1):
        scan_port(ip_address, port)

import socket

        sock.connect((ip_address, port))
        print(f"Port {port} is open on {ip_address}")
    except socket.error:
        pass

def scan_ports(ip_address, start_port, end_port):
    for port in range(start_port, end_port+1):
        scan_port(ip_address, port)

if __name__ == "__main__":

    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.settimeout(1)
    scan_ports(ip_address, start_port, end_port)
    sock.close()
