Summary
There a two main network models in use: TCP/IP and OSI. These net-
working models use a layered approach to handle the data being received and
transmitted. Each layer provides a different service of coordinating commu-
nication or transforming data. Collectively, these layers are referred to as a
protocol stack.
In the TCP/IP network model, the Internet Protocol (IP) at the Internet
Layer is used to segregate networks into classes. The three most commonly
used IP network classes are A, B, and C.
Three files are used to configure TCP/IP on a Solaris 9 system. These are
/etc/inet/hosts
,
/etc/nodename
, and
/etc/hostname.
interface
.
Two commonly used commands to view network interface status are
ifconfig
and
netstat
.
Most network services are controlled by the
inetd
daemon, which starts the
services as needed.
