局域网电脑远程监控程序
包括服务器端和客户端
在一台机器运行服务器程序
客户端运行客户端程序
可以动态监视服务器的屏幕
能将鼠标和键盘事件传过去，能进行一般的操作
运行环境:jdk1.4.1(能处理鼠标滚轮的事件)
我在三台机器分别是
win2000 ad server
winxp profession
redhat linux 8.0
上进行了测试，都可以运行服务器端和客户端，并能工作
支持一台服务器多台客户端，大家一起操纵，呵呵

客户端源程序已经编写了，正在完善中。欢迎大家来信咨询,在我的主页已经公开源代码了！


//客户端源代码：

使用方法：
先在服务器运行服务器端程序
再在客户端运行客户端程序(不要运行在一台机器上，你会发现鼠标很奇怪)
在客户端右击中间区域，单击那个菜单项，输入服务器的地址
ok
让我继续来完善
