Problem:
If you want to define a static fully qualified domain name (FQDN) on your windows XP/Server 2003 machine, so that your computer does not contact a DNS server to resolve a particular IP address then you can do so by using the instructions explained below.
Scenario:
This can be useful on a number of situations one such situation is as follows.
Let's say you have a web server hosting www.example.com and you want to add a new machine to this web address for load balancing purposes. Once you are done setting up the new machine you'll test it by using the direct IP address of that machine. You cannot access the new machine using www.example.com because every time you try that your computer will be forwarded to the old machine (whose IP address is stored in the DNS server). In this situation you can use the instructions below to give a static IP address (IP address of the new machine) to www.example.com, so that your computer connects with the new server (when you access it) using www.example.com.
If you want to compile and install Open Source Software on your MacOS X machine then you should install MacOS X's Xcode tools. Xcode tools provide the compilers and other software development kits (SDKs) to enable you to compile and install open source software on your computer.
