Red Hat Network Computing Environments

TCP/IP and Linux Networking using netstat, arp, and ifconfig

Networks are complex computing environments. You must coordinate your computer's configuration with the setup of your network.
If errors in configuration do occur, Red Hat Linux provides the tools you need to find and correct the problems.
Accessing networks over modem lines requires the configuration of your modem, PPP interface, and dial-up connections. Red Hat Linux also comes with graphical tools to make these configurations and connections happen easily.

Learning objectives

After completing this module, you will be able to:
  1. Describe the function of netstat, arp, and ifconfig
