Chapter 17. Getting on the Internet > Making the Connection - Pg. 202

Getting on the Internet 202 usually called) can take advantage of well-known vulnerabilities to look around or even commandeer your machine. To protect yourself, you need to block those vulnerabilities by setting up what's known in the security trade as a firewall . To check that your computer is connected, use Internet Explorer to go to and click the Shields Up link (you may have to click Shields Up again on the new page that appears). Configuring Advanced ISP Settings If your ISP requires you to configure any of the advanced settings that I mentioned earlier, let's see how you do it. Begin by selecting Start, Connect To, Show all connections. Click your connection and then click Change settings of this connection (or choose the File, Properties command). You use the Properties dialog box to put in the advanced settings: · If you need to log on to the ISP manually, display the Security tab and activate the Show terminal window check box. · If your ISP provides you with a "script" for automating the logon procedure, display the Secur- ity tab and activate the Run script check box. Then click Browse to locate the script file on your computer. · For the type of connection, display the Networking tab and then use the Type of dial-up server I am calling list to choose either PPP or SLIP. · If your ISP assigns you a permanent IP address, display the Networking tab, highlight Internet Protocol (TCP/IP) and then click Properties. Activate Use the following IP address and then enter your IP address in the IP address text box. · If your ISP provides you with IP addresses for their Domain Name Servers (DNS), display the Networking tab, highlight Internet Protocol (TCP/IP) and then click Properties. Activate Use the following DNS server addresses and then enter the DNS server addresses in the Preferred DNS Server and Alternate DNS Server text boxes. Making the Connection Now that you have your account details down pat, it's time to put that account to good use by connecting to the Internet. There are two ways to go about this: · Crank up any of the Internet programs. For example, you can launch the Internet Explorer Web browser. · Select Start, Connect To and then click the Internet connection you created. At this point, Windows XP might mumble something about The Web Page You Requested Is Not Available Offline. Say "Well, duh!" and click Connect. This gets you to a Connect dialog box that's similar to the one shown in Figure 17.1.
