This tutorial assumes that you already know the basics of GNU/Linux. It won't teach you the basic things like editing a file, cp, rm, etc. .. Throughout the tutorial we will assume Redhat 7.2 distribution though the commands are similar in other distribution. This tutorial will teach you only the very minimum basics of networking. I will try to update this guide whenever i get free time. Slowly TCP/IP became the de-facto standard for Internet Communications. Nowadays almost all the Intranet also started using TCP/IP. But remember TCP/IP is not the only protocol available for networking. Several other protocols like IPX/SPX, AppleTalk Protocol, etc. . . are also in use. If you install TCP/IP in all the computers then you can establish communication with each other by properly configuring each of them. GNU/Linux comes with inbuilt TCP/IP support in the kernel. So you don't have to do anything special to install TCP/IP. Routing If you want to connect your host to more than one network � say, three network, then you will need three ethernet card to connect to the three networks. Thus, a host may contain more than one ethernet card. Such a host is called a "multi-homed" host. Sometimes, you want to pass data from one network to another network. For such a situation, you can use a multi-homed host by configuring the host to forward data between a pair of ethernet cards. |
