Directory not empty表示目录不空。Too many symbolic links encountered表示遇到太多符号链接。Operation would block表示操作会被阻塞。No message of desired type表示没有所需类型的消息。Identifier removed表示标识符被删除。Channel number out of range表示通道号超出范围。Level 2 not synchronized表示第二...
只能从IP数据报的数据部分开始构造,想要构造IP首部就要用到原始套接字,用原始套接字可以从IP首部开始构造,但是如果用原始套接字需要root权限,开始我在OS X下用IDE,程序总是报错socket.error: [Errno 1] Operation not permitted,就是因为权限的问题,在终端里sudo运行就没有权限问题了(Ps:如果想用...

Socket是网络编程的一个抽象概念。通常我们用一个Socket表示“打开了一个网络链接”,而打开一个Socket需要知道目标计算机的IP地址和端口号,再指定协议类型即可。 客户端 大多数连接都是可靠的TCP连接。创建TCP连接时,主动发起连接的叫客户端,被动响应连接的叫服务器。 举个例子,当我们在浏览器中访问新浪时,我们自己的...
设置端口号、主机IP，创建socket，运行代码。完整代码如下。在运行过程中，可能遇到Java.net.SocketException: socket failed: EPERM (Operation not permitted)的错误提示。这表明Android程序的网络权限未开启。需在AndroidManifest.xml中添加网络权限。最终效果：单击一次按钮实现一次数据传输。
但是如果用原始套接字需要root权限,开始我在OS X下用IDE,程序总是报错socket.error: [Errno 1] Operation not permitted,就是因为权限的问题,在终端里sudo运行就没有权限问题了(Ps:如果想用root权限打开IDE,又不想切换账户的话,终端里sudo ./IDE就行了)现在有了权限,开始报别的错了,提示socket.error: [...
