Figure 10-8:
Using the Certificate Wizard to generate a unique certificate for your VPN.
Don’t forget your password — this is used every time you log onto the VPN.
2. The results of Step 1 include a private key (which is created in your C:\Program Files\WiTopia.Net\config folder, and a certificate request key (which is a bunch of gobbledygook on your screen beginning with
the words------begin certificate request------------). Select this text
and press Ctrl+C to copy it onto your clipboard.
Don’t close this window just yet — you may need to come back and recopy the certificate request text, just in case you accidentally clear your clipboard.
3. Switch to your e-mail program and click the link that says To activate personalVPN service from WiTopia, click the following link: in your e-mail from WiTopia.Net (the exact URL is different for every customer).
The link opens in your Web browser (if it doesn’t, cut and paste the link into a new browser window).

4. Follow the steps onscreen, including the pasting of the certificate request text.
When you’re done, close any remaining open WiTopia programs and go about your business. You need to wait for up to a day for your certificate to be generated and e-mailed back to you.
You soon get an e-mail from WiTopia containing two files: your certificate (named FirstName_LastName.crt — substitute your actual name as you registered yourself), and a .zip file containing that certificate (.crt) file. You get both because some e-mail programs don’t handle .crt files very well — for example, with Lotus Notes and Gmail (the two mail systems we use), you can’t open a .crt file at all — the .zip file helps you get around this. Open this e-mail and see which of the two files you can access. Depending on what you see, follow these steps:
a. If you can access the .crt file, simply save it in the c:\Program Files\WiTopia.Net\config directory on your computer using your e-mail client’s standard Save process.
b. If you can’t see the .crt file, but you can see the .zip file, simply open the .zip file with your favorite .zip decompression utility (we like WinZip — www.winzip.com — but any .zip utility can handle this task), and save it to that same directory.
c. If you can’t see either file, your e-mail program isn’t handling the certificate files in a friendly way at all (Gmail does this, unfortunately). Reply to the e-mail you’ve received with a different e-mail address, and the certificates are forwarded to you again.
After you’ve installed that certificate file, you’re ready to go. The OpenVPN GUI client is installed in the Windows taskbar on your computer. To make your VPN connection, simply right-click the icon and select Connect. Enter your password (the one you created in Step 1) in the OpenVPN Connection window that pops up (shown in Figure 10-9).

184 Part III: Wireless on the Go
You are connected to the WiTopia.Net VPN server and your connection is secure. You see a notification (shown in Figure 10-10) above your taskbar showing the new public IP address of your VPN connection. (Your computer will no longer use the public IP address of the Wi-Fi network you are connected to, but instead will appearto be located in WiTopia’s data center.)

Chapter 11
Outfitting Your Car with Wireless
In This Chapter
^ Linking your cellphone to your car radio ^ Checking out GPS
^ Synching your car to your home music system ^ Watching for viruses in your automobile ^ Setting up wireless caravans on the road
ireless technologies have been creeping into the car ever since Paul
▼ ▼ Galvin, the head of Galvin Manufacturing Corporation, invented the first car radio back in 1929. Not unlike many new technologies for cars today, the first car radios back then were not available from carmakers; instead, you bought a retrofit kit from Galvin’s company. Galvin coined the name Motorola for the company’s new products. The rest is, as we say, history.
Today, you can still add neat new wireless gizmos to your car, but you’re still likely to have to do so via some sort of third-party device. Only a few high-end cars even offer any sort of wireless integration into the car, and even then it’s usually limited to putting a cellphone into the dashboard.
We’ve got better ideas than that, and this chapter tells you how to add Bluetooth, Wi-Fi, and even satellite TV to your car. And as a bonus, we also tell you how to seamlessly integrate your cellphone into the equation. If you love cars as much as Pat does, this will simply be an irresistible set of first projects for you to tackle!
In this chapter, we don’t spend a lot of time talking about cellular phone or related data services themselves, but instead focus on how to link your cellphone to your car to take advantage of that mobile data stream.
