创建TCP服务器的一种简单方式就是利用socketserver库。比如, 下面是一个简单的echo服务示例: from socketserver import BaseRequestHandler, TCPServer class EchoHandler(BaseRequestHandler): def handle(self): print('Got connection from ', self.client_address) while 1: msg = self.request.recv(8192) if ...

Windows 8, Python 2.7, firewall is turned off. Code is from here: https://wiki.python.org/moin/TcpCommunication If I do the client stuff (socket(...), connect(...), send(...)) via python repl, things work fine, ie the server correctly blocks when calling recv. Howev...
./server & ./client 通过bt可以查看到进入tcp_v4_connect时的堆栈,因此我们已经可以逐步调试TCP/IP的源码了。 2.8 环境配置总结 通过前述一系列的操作我们就可以像调试普通程序一样调试 Linux 内核了。Linux 的内核入口函数是位于 init/main.c 中的 start_kernel,相当于普通 C 程序的 main 函数,负责完成各种内...
