如何查看是否侦听udp端口

netstat -anu | grep LISTEN

ss -uan | grep LISTEN

netstat -an | findstr "UDP"

import socket

def check_udp_port(ip, port):
    with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as s:
        try:
            s.bind((ip, port))
            return True  # 端口未被监听，可以绑定
        except socket.error as e:
            if e.errno == 98:  # 地址已在使用
                return False  # 端口已被监听
            else:
                raise  # 其他错误

# 使用示例
ip = '127.0.0.1'
port = 5005
is_listening = not check_udp_port(ip, port)
print(f"UDP端口 {port} 是否被监听: {is_listening}")
