给大家推荐一个好工具--vnc
前言：我们单位用的是10m的宽带，电信局只分了一个ip地址，所以我们用了一台ibm服务器兼作代理，用的是sygate。原服务器只有一个网卡，后又加了一块。但是不知为什么sygate老是无故停止服务。经查是网卡兼容性问题。于是网管在服务器上装了winvnc，用于远程控制。我昨天重装rh9是发现rh9自带了vnc server，我为了上班能学习linux(我家里的机器也在单位的局域网里挂着)，就查了一下vnc的用法

我在家里的机器上执行
vncserver
然后输入访问密码。
在单位机器(windowsxp)上打开ie，输入
http://192.168.x.x:5801
(192.168.x.x为家里机器的ip地址,5801为端口号，一般为5800，有几层防火墙加几。)
然后输入vnc的密码。即可在ie里看到linux的界面，也可以操作，方便之极。
有兴趣的朋友可以仔细研究一下。 VNC is a good tool for remote desktop control, especially, when you have a long-run task running and want to check its status regularly. e.g., you can run the task on your lab machine and check its state at home.
BTW, I think Linux supports VNC better than Windows. Running VNC server on linux allows you to have seperate desktop for a remote user without interfering current desktop user. This is the benifit of X-server architecture. It is also possible (I think) to run several VNC servers listening on different ports for resource-sharing purpose. Under Windows, a remote user has to sharethe desktop with current desktop user. Thus, only one user is allowed to control the machine at the same time.
