import logging
import socket

BUFF_SIZE = 2048

LOG_FILENAME = "record_ip.log" # 日志文件名
MSG = b'Hello World'
ADDRESS = ('127.0.0.1', 2134) # 这里的IP应该填外网的

# 配置日志输出文件及级别
FORMAT = '%(asctime)s::%(levelname)s::%(message)s'
logging.basicConfig(filename=LOG_FILENAME, level=logging.INFO, format=FORMAT, filemode='a')

# 日志同时输出到控制台
console = logging.StreamHandler()
console.setLevel(logging.INFO)
console.setFormatter(logging.Formatter(FORMAT))
logging.getLogger('').addHandler(console)

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.bind(ADDRESS)

while True:
    data, addr = s.recvfrom(BUFF_SIZE)
    if data == MSG:
        logging.info('IP: %s' % addr[0])

客户端每隔一段时间向服务器发送消息。
