problem, people often build dual-boot or multi-boot workstations.
You can use a product like Symantec’s PartitionMagic (www.symantec.com/
partitionmagic) to set up partitions for the various operating systems. For more information about setting up and using PartitionMagic, among other things, check out Kate Chase’s Norton All-in-One Desk Reference For Dummies (Wiley). After you set up your partitions, you install the operating systems on the various partitions.
When everything’s installed, you can select the operating system you want to use when you boot the system. Say you’re using NetStumbler on Windows XP
and you decide to use WEPcrack — which is available only on Linux — on the access points you just identified with NetStumbler. You shut down Windows XP, reboot your system, and select the Red Hat Linux operating system. When you want to use Windows XP again, you must do the reverse. This isn’t a bad solution, but flipping back and forth a lot eats up valuable time. And managing your partitions and trying to make the operating systems coexist on the same hardware can be challenging.
Enter software emulators. Software emulators allow you to emulate a guest operating system by running it on top of a host operating system. You can run Linux emulation on a Windows host, and vice versa. To emulate Windows or DOS on a Linux host, you can choose one of the following Windows-based emulators:
ߜ Bochs (http://bochs.sourceforge.net)
ߜ DOSEMU (www.dosemu.org)
ߜ Plex86 (http://savannah.nongnu.org/projects/plex86)
ߜ VMware (www.vmware.com)
ߜ WINE (www.winehq.com)
ߜ Win4Lin (www.netraverse.com)
Alternatively, you can emulate Linux on a Windows host. To do this, choose one of the following Linux-based emulators:
ߜ Cygwin (http://cygwin.com)
ߜ VMware (www.vmware.com)

Mac lovers can already run most of the UNIX tools under the Mac OS. To emulate the Windows environment, you can run an emulator like Microsoft Virtual PC (www.microsoft.com/mac/products/virtualpc/virtualpc.
aspx?pid=virtualpc).
To get you going, the next two sections discuss Cygwin and VMware, two excellent examples of emulation software.
Setting up Cygwin
Do you use Windows but have software that only runs on Linux? If so, Cygwin is your answer. Cygwin is a contraction of Cygnus + Windows. It provides a UNIX-like environment consisting of a Windows dynamically linked library (cygwin1.dll). Cygwin is a subsystem that runs on Windows and intercepts and translates UNIX commands. This is transparent to the user. With Cygwin, you can have the experience of running xterm and executing ls commands without ever leaving your safe Windows environment.
First, download Cygwin by going to http://cygwin.com. Installing Cygwin is easy when you follow these steps:
1. On the home page, click the Install or Update Now! (Using setup.exe) link about halfway down the page.
You see a File Download – Security Warning window.
2. Click Run to download Cygwin.
You see the message shown in Figure 4-1.
3. Click Run to run setup.exe.
You see the Cygwin Setup window shown in Figure 4-2.

This is the installation type. If you have a CD-ROM with Cygwin, select Install from Local Directory instead.
