呼呼！终于要来到修改 Linux 网路参数的章节了！在前面的 <a href="0110network_basic.php">网路基础</a>
章节内我们知道了主机要连上 Internet 需要一些正确的网路参数设定，这些设定在
Windows 系统上面的修改则在 <a href="0120intranet.php">区域网路的架构</a>
里面进行了说明。在这一章当中，我们则主要以固定 IP 的设定方式来修改 Linux
的网路参数，同时，也会介绍如何使用 ADSL 的拨接方式来上网，此外，因为 Cable
modem 使用者也不在少数，所以我们也说明一下 Cable modem 在 Linux 下的设定方式喔！
最后，由于笔记型电脑使用者大增，由于笔记型电脑常使用无线网路，因此本文也加入了无线网路的连线介绍啊！

要连上 Internet 时，由前几章的资料来说，我们知道需要设定一组网路参数，
包括 IP, netmask, network, broadcast, gateway 以及 DNS 主机的 IP 等等，
那我们也知道，其实整个主机最重要的设定，就是『先要驱动网路卡』，否则主机连网路卡都捉不到时，
怎么设定 IP 参数都是没有用的，您说是吧！所以底下我们就来谈一谈，
您要如何确定网路卡已经被捉到，而 Linux 主机的网路参数又该如何设定？<br /><br />
