一部连上 Internet 上面的您的个人主机，最重要的是什么呢？
大概就是如何让您自己可以连线进入自己的主机，并且进行所谓的『远端操控』了吧！
也就是说，您可以在任何具有连上 Internet 的电脑中，以远端连线软体连上 Internet
，并藉由您主机上面的远端连线伺服器软体提供的功能，直接登入您的主机来进行操控的工作！此时，您将发现
Linux 有趣又好玩的地方棉！在早期的 Unix Like 机器当中，几乎都提供 Telnet 这个远端连线伺服器软体，不过，
Telnet 本身是以『明码』来传送您操作的资料，安全上面是值得来思考要不要开放呐！
这个时候就有需要了解一下传送过程中以加密动作来传送资料封包的
SSH 这个远端连线伺服器软体啦！
另外，除了纯文字介面登入主机来进行操控之外，在现在的 Linux distributions 当中，
还可以利用 X 相关的服务来帮助我们以图形介面登入喔！很棒吧！ ^_^
