Python is growing in popularity; based on download statistics, there are now over 450,000 people using Python, and more than 150,000 people using Python on Windows. Use of the language has been growing at about 40% per year since 1995, and there is every reason to believe that growth will continue. Despite Python's increasing popularity on Windows, Python Programming on Win32 is the first book to demonstrate how to use it as a serious Windows development and administration tool. Unlike scripting on Unix, Windows scripting involves integrating a number of components, such as COM or the various mail and database APIs, with the Win32 programming interface. While experienced Windows C++ programmers can find their way through the various objects, most people need some guidance, and this book is it. It addresses all the basic technologies for common integration tasks on Windows, explaining both the Windows issues and the Python code you need to glue things together. Topics include: * The Python language and the PythonWin extensions * Building a GUI with COM * Adding a Macro language * Distributing the application * Client-side COM for output and data access * Integration with mail and other internet protocols * Managing users and drives This is a vital and unique book. Python Programming on Win32 is an excellent presentation of Windows application development and a solid illustration of how to use Python in the Windows environment.

In the five years since the first edition of this classic book was published, Internet use has exploded. The commercial world has rushed headlong into doing business on the Web, often without integrating sound security technologies and policies into their products and methods. The security risks--and the need to protect both business and personal data--have never been greater. We've updated Building Internet Firewalls to address these newer risks. What kinds of security threats does the Internet pose? Some, like password attacks and the exploiting of known security holes, have been around since the early days of networking. And others, like the distributed denial of service attacks that crippled Yahoo, E-Bay, and other major e-commerce sites in early 2000, are in current headlines. Firewalls, critical components of today's computer networks, effectively protect a system from most Internet security threats. They keep damage on one part of the network--such as eavesdropping, a worm program, or file damage--from spreading to the rest of the network. Without firewalls, network security problems can rage out of control, dragging more and more systems down. Like the bestselling and highly respected first edition, Building Internet Firewalls, 2nd Edition, is a practical and detailed step-by-step guide to designing and installing firewalls and configuring Internet services to work with a firewall. Much expanded to include Linux and Windows coverage, the second edition describes: * Firewall technologies: packet filtering, proxying, network address translation, virtual private networks * Architectures such as screening routers, dual-homed hosts, screened hosts, screened subnets, perimeter networks, internal firewalls * Issues involved in a variety of new Internet services and protocols through a firewall * Email and News * Web services and scripting languages (e.g., HTTP, Java, JavaScript, ActiveX, RealAudio, RealVideo) * File transfer and sharing services such as NFS, Samba * Remote access services such as Telnet, the BSD "r" commands, SSH, BackOrifice 2000 * Real-time conferencing services such as ICQ and talk * Naming and directory services (e.g., DNS, NetBT, the Windows Browser) * Authentication and auditing services (e.g., PAM, Kerberos, RADIUS); * Administrative services (e.g., syslog, SNMP, SMS, RIP and other routing protocols, and ping and other network diagnostics) * Intermediary protocols (e. g., RPC, SMB, CORBA, IIOP) * Database protocols (e.g., ODBC, JDBC, and protocols for Oracle, Sybase, and Microsoft SQL Server) The book's complete list of resources includes the location of many publicly available firewall construction tools.

If you're seeking ways to build network-based applications or XML-based web services, Microsoft provides most of the tools you'll need. XML is integrated into the .NET Framework and Visual Studio .NET, but if you want to get a grasp on how .NET and XML actually work together, that's a different story. With .NET & XML, you can get under the hood to see how the .NET Framework implements XML, giving you the skills to write understandable XML-based code that interoperates with code written with other tools, and even other languages. .NET & XML starts by introducing XML and the .NET Framework, and then teaches you how to read and write XML before moving on to complex methods for manipulating, navigating, transforming, and constraining it. To demonstrate the power of XML in .NET, author Niel Bornstein builds a simple hardware store inventory system throughout the book. As you move from chapter to chapter, you'll absorb increasingly complex information until you have enough knowledge to successfully program your own XML-based applications. This tutorial also contains a quick reference to the API, plus appendices present additional .N ET assemblies that you can use to work with XML, and how to work with the .NET XML configuration file format. One study puts the potential market for new software based on XML at or near $100 billion over the next five years. The .NET Framework gives you a way to become a part of it. But to use XML and .NET effectively, you need to understand how these two technologies work together. This book gives you the insight to take full advantage of the power the two provide.

Apache is the most popular Web server on the Internet because it is free, reliable, and extensible. The availability of the source code and the modular design of Apache makes it possible to extend Web server functionality through the Apache API. For the most part, however, the Apache API has only been available to C programmers, and requires rebuilding the Apache server from source. mod_perl, the popular Apache module used primarily for enhanced CGI performance, changed all that by making the Apache API available to Perl programmers. With mod_perl, it becomes simple to develop Apache modules with Perl and install them without having to rebuild the Web server. Writing Apache Modules with Perl and C teaches you how to extend the capabilities of your Web server regardless of whether you use Perl or C as your programming language. The book explains the design of Apache, mod_perl, and the Apache API. It then demonstrates how to use them to perform for tasks like the following: Rewriting CGI scripts as Apache modules to vastly improve performance Server-side filtering of HTML documents, to embed special markup or code (much like SSI) Enhancing server log functionality Converting file formats on the fly Implementing dynamic navigation bars Incorporating database access into CGI scripts Customizing access control and authorization to block robots or to use an external database for passwords The authors are Lincoln Stein and Doug MacEachern. Lincoln is the successful author of How to Set Up and Maintain a World Wide Web Site and the developer of the widely used Perl CGI.pm module. Doug is a consultant and the creator of the innovative mod_perl Apache module.

Historically, only large companies could afford secure networks, which they created from expensive leased lines. Smaller folks had to make do with the relatively untrusted Internet. Nowadays, even large companies have to go outside their private nets, because so many people telecommute or log in while they're on the road. How do you provide a low-cost, secure electronic network for your organization? The solution is a virtual private network: a collection of technologies that creates secure connections or "tunnels" over regular Internet lines -- connections that can be easily used by anybody logging in from anywhere. A number of products now exist to help you develop that solution. This book tells you how to plan and build a VPN. It starts with general concerns like costs, configuration, and how a VPN fits in with other networking technologies like firewalls. It continues with detailed descriptions of how to install and use VPN technologies that are available for Windows NT and UNIX, such as PPTP and L2TP, Altavista Tunnel, Cisco PIX, and the secure shell (SSH). New features in the second edition include SSH, which is a popular VPN solution for UNIX systems, and an expanded description of the IPSec standard, for which several vendors have announced support. Topics include: How the VPN compares to other available networking technologies Introduction to encryption, firewalls, the IPSec standard, and other technologies that let VPNs work Point to Point Tunneling Protocol (PPTP) and LT2P The Altavista Tunnel The Cisco PIX Firewall Secure Shell (SSH) Maintenance and troubleshooting
