What You've Learned You need to understand the basics of IP networking to be able to configure and troubleshoot IP networks. In Mac OS X, simple networking configuration is done with the Network Setup Assistant. Additional configuration is done in Network preferences. AppleTalk is no longer enabled by default. AppleTalk also has changed in Mac OS X 10.4, in that it is now used only for printers and not for AFP file services. A proxy server can significantly reduce your Internet traffic for commonly-used sites or for sites with large graphic files. To effectively troubleshoot your IP network, you need to be familiar with the network topology. Mac OS X provides you with a set of network tools that can help you in troubleshooting. These tools (Ping, Lookup, Traceroute, and Port Scan) are in Network Utility (/Applications/Utilities). You can use Network Utility or Terminal from the Mac OS X Install DVD to troubleshoot local, network, and server problems.
