Basic Linux TrainingLesson 15: Linux Telecommunications and Networking
Table of Contents
Note: This lesson is extremely short. Most of you are not going to need this information immediately. Just read through the first four online URLs, and be aware that there is much more information readily available online if you ever need it.
BackgroundThe original concept behind uucp was to provide reliable file transfer facilities among Unix machines over telephone lines using inexpensive, low--speed, dial-access modems. (At the time, the technique was using acoustic couplers, and the fastest speeds were around 300 baud.) This enabled any Unix machine to connect to another Unix machine anywhere in the world using existing telephone lines, and was particularly well suited for e-mail transport. uucp is still a viable low-cost alternative to setting up an e-mail and FAX network.With TCP/IP, the Unix-exclusive aspect was eliminated - any machine could connect with any other machine, regardless of hardware or operating system. Without TCP/IP the Internet would be closed to millions of users using different platforms.
NetworkingThere are a number of ways to implement a network, most of it well beyond the scope of this course. However, some of us have a second computer which can be connected in a simple point-to-point network configuration, and adding additional computers is a fairly straightforward extension called a Multiport network configuration with additional terminals dropped off the same communications line rather than the single remote station in point-to-point.Ethernets are not terribly expensive or difficult to set up for home users: a network card for each computer you want to connect, and an extra one to make the connection to the Internet, some cable and connectors; a little reading, a little work, a little tinkering with the scripts, and a lot of patience and you'll be finished quickly and cleanly. Seyon and minicom provide you will powerful tools for making the connection over a telephone line, and the terminal emulation facilities in seyon are very impressive. You're not restricted to the Internet, you can connect to any computer with a modem and use the telephone. Or you might consider starting a bbs (Bulletin Board Service) or a freenet.

(These should be all you will need, and are all that is required for this course.)
However, if you are setting up a network for your business, or want to put a server on the Internet, you'll have to do a lot more reading. (These are not required for this course. Just be aware that a sysadmin does have to know this stuff.)
