| - | ====== TIME_WAIT issue after closing the socket ====== | ||
| - | ===== Problem ===== | ||
| - | <code python> | ||
| - | import socket | ||
| - | import os | ||
| - | import sys | ||
| - | def acceptConn(s): | ||
| - | while True: | ||
| - | conn = None | ||
| - | try: | ||
| - | conn, addr = s.accept() | ||
| - | data = conn.recv(1024) | ||
| - | data = data.strip() | ||
| - | |||
| - | print data | ||
| - | if data == 'exit': | ||
| - | break | ||
| - | except: | ||
| - | print sys.exc_info()[0] | ||
| - | finally: | ||
| - | if conn is not None: | ||
| - | conn.close(); | ||
| - | conn = None | ||
| - | |||
| - | s = None | ||
| - | try: | ||
| - | s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) | ||
| - | s.bind(('0.0.0.0', 4444)) | ||
| - | s.listen(1) | ||
| - | acceptConn(s) | ||
| - | finally: | ||
| - | if s is not None: | ||
| - | s.shutdown(1) | ||
| - | s.close() | ||
| - | </code> | ||
| - | ===== How to? ===== | ||
| - | 參考[[https://docs.python.org/2/library/socket.html|python document]]，在create socketc後做以下設定: | ||
| - | <code python> | ||
| - | s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) | ||
| - | </code> | ||
| - | 這讓kernel知道我們可以重複使用TIME_WAIT的socket。 | ||
