Basic Networking
Linux offers the necessary networking tools and features for integration into all types
of network structures. The customary Linux protocol, TCP/IP, has various services and
special features, which are discussed here. Network access using a network card, modem,
or other device can be configured with YaST. Manual configuration is also possible.
Only the fundamental mechanisms and the relevant network configuration files are
discussed in this chapter.
Linux and other Unix operating systems use the TCP/IP protocol. It is not a single
network protocol, but a family of network protocols that offer various services. The
protocols listed in Table 30.1, "Several Protocols in the TCP/IP Protocol Family"
(page 548) are provided for the purpose of exchanging data between two machines via
TCP/IP. Networks combined by TCP/IP, comprising a worldwide network are also re-
ferred to, in their entirety, as "the Internet."
RFC stands for Request for Comments. RFCs are documents that describe various In-
ternet protocols and implementation procedures for the operating system and its appli-
cations. The RFC documents describe the setup of Internet protocols. To expand your
knowledge about any of the protocols, refer to the appropriate RFC documents. They
are available online at http://www.ietf.org/rfc.html.
