Java开发的屏幕监控源代码也可以在Linux上使用

Java Linux Socket IE OS

本案例分两个类Server类和Client类，其余的类为内部类。该案例纯属Java编程。
并且已经在Linux上测试通过。

屏幕监视设计思想：http://www.blackswansoft.com/songhaikang/article/20110221105156640.html

推荐软件

用java开发的一款功能强大的开源的远程控制软件，最近又升级了，添加了许多使用的功能，而且代码也有了很大程度的优化。可以实现生成服务器、修改上线主机名称、屏幕监视，屏幕控制、主动连接、上传文件、下载文件、远程命令、远程任务管理器、发送警告、相互聊天、换皮肤、版本升级提醒等功能，通过该软件可以实现用一台电脑同时控制多台电脑，也可以多台电脑控制同一台电脑等。
