The Ports Properties dialog box is shown in Figure 9-22. You open this dialog box by right-clicking the Ports node in the Routing And Remote Access console and clicking Properties. By selecting the modem used in the demand-dial connection and clicking the Config ure button, you open the Configure Device dialog box, as shown in Figure 9-23. This dialog box enables you to configure the modem for either inbound only or inbound and outbound connections. It also allows you to specify a phone number for the device. This number can be read by the calling interface and can be used for remote access pol icies that use the Called-Station-Id attribute. The phone number is required for BAPenabled connections and is dialed by the client when additional connections are created.

Reward good code Use your organization s reward system to reinforce good coding practices. Keep these considerations in mind as you develop your reinforcement system:

Figure 9-22

The reward should be something that the programmer wants. (Many programmers find attaboy rewards distasteful, especially when they come from nontechnical managers.) Code that receives an award should be exceptionally good. If you give an award to a programmer everyone else knows does bad work, you look like Charlie Chaplin trying to run a cake factory. It doesn t matter that the programmer has a cooperative attitude or always comes to work on time. You lose credibility if your reward doesn t match the technical merits of the situation. If you re not technically skilled enough to make the good-code judgment, don t! Don t make the award at all, or let your team choose the recipient.

secure. It produces a challenge to the server to identify itself, but unautho rized users can still obtain the credentials with minimal effort.

One easy standard If you re managing a programming project and you have a programming background, an easy and effective technique for eliciting good work is to say I must be able to read and understand any code written for the project. That the manager isn t the hottest technical hotshot can be an advantage in that it may discourage clever or tricky code.

A final management feature associated with the Ports node is the Port Status dialog box. When you select the Ports node in the Routing And Remote Access console, the list of connection ports is listed in the details pane. This list includes the available modem device or devices. You can view details about the status of a modem by double-clicking the modem device and opening the Port Status dialog box. This dialog box presents sta tistics about a modem (when active) and allows you to reset the modem connection.

These management features are accessible through the IP Routing node of the Routing And Remote Access console. When you select the General node within the IP Routing node, the interfaces configured for your server appear in the details pane. Rightclicking a demand-dial interface reveals various demand-dial management and troubleshooting commands, as shown in Figure 9-24.

Most of this book is a discussion of good programming practices. It isn t intended to be used to justify rigid standards, and it s intended even less to be used as a set of rigid standards. Using it in such a way would contradict some of its most important themes. Use this book as a basis for discussion, as a sourcebook of good programming practices, and for identifying practices that could be beneficial in your environment.

one-way encryption of credentials and one-way authentication of the client to the server. MS-CHAP v2 offers better security by supplying mutual authen tication of both the client and the server to each other. If you are considering MS-CHAP, you might as well use MS-CHAP v2.

A software project is dynamic. The code changes; the design changes; the requirements change. What s more, changes in the requirements lead to more changes in the design; changes in the design lead to even more changes in the code and test cases.
