The focus of this IBM Redbook is networking infrastructure aspects of modernizing an SNA network environment. Additionally, modernizing SNA concerns itself with how to modernize access to existing SNA core business applications. In order to provide a reference model for modernizing SNA, this book introduces a selected set of SNA application access modernization technologies, which go beyond the normal networking infrastructure. Some of the technologies discussed in this book aim at improving the user experience when accessing traditional SNA 3270 applications and at exposing existing mainframe SNA applications as Web services. Such technologies will primarily be introduced from a network topology and connectivity perspective. While a description of the full set of capabilities of such technologies is beyond the scope of this document, readers can refer to other technology-specific and product-specific documentation from IBM and other vendors for that information. The intended audience for this book are IBM System z technical managers, system architects, and network administrators who are responsible for setting the overall strategic directions for an enterprise networking infrastructure. This infrastructure includes Systems Network Architecture (SNA) and Internet Protocol (IP) networking technologies, branch or remote location access networks, data center connectivity, and business partner connectivity.

The industry's premier Java-based emulator, IBM WebSphere Host On-Demand V5, has been enhanced to provide many new usability and manageability features. Enhancements in the client include improved client customization support for color and keyboard mappings as well as improved navigation. Host printing from Windows is made easier, while VT print passthrough is provided. AS/400 improvements abound, including support for ENPTUI, Toolbox Model 3 and AS/400 Proxy. The VT use is not forgotten. Included are VT100/200 enhancements, a VT history window and support for greater than 24 lines. Security is enhanced by providing an express logon capability using digital certificates. Major improvements in the manageability and deployment of IBM WebSphere Host On-Demand V5 are included in this release. Included is a new configurable smart client, a Deployment Wizard for creating and managing customized Web pages, the ability to disable unnecessary functions, native platform authentication, and the componentization of the clients that will allow for updating of individual functions instead of the entire product.

This redbook will help you install, configure, administer and use IBM SecureWay Host On-Demand Version 4. Host On-Demand consists of a server and several clients, certified 100% pure Java, that provide terminal-emulator sessions to System/390, AS/400 and ASCII host systems through a Web browser. The server can be installed on Windows NT, OS/2, NetWare, AIX, various types of UNIX, OS/400 or OS/390. Now that we are into the era of "computing on the Web", there is a need for products that let customers, agents, suppliers, distributors and other business partners, as well as employees, have access to a company's host systems over the Internet or intranet; Host On-Demand is just such a product. This book describes all the functions of Host On-Demand, from the point of view of both administrator and user. It explains how the product works and the variety of ways in which it can be configured to suit differing requirements, and it discusses and makes recommendations about data security, which is often of vital importance in this environment. Many enhancements have been made in Version 4. Many people nowadays want to present host-system screens in a graphical format that is familiar to the modern-day user. IBM Screen Customizer lets you convert "green screens" easily and quickly into windows that include images, buttons, links, dialog-boxes and all the other attributes of a modern graphical interface. The book includes a chapter on this product.

Beyond DHCP — Work Your TCP/IP Internetwork with Dynamic IP explores important network design issues for today's modern mixed intranets. The authors discuss many different platforms, including Windows 95, Windows 98, Windows NT, OS/2 Warp, OS/2 Warp Server, AIX, Macintosh, WorkSpace On-Demand, Linux, Solaris, and others. The book examines how to connect these systems in a reliable, flexible, high-performance TCP/IP network. When confronted with thorny TCP/IP problems, network specialists, support staff, network managers, and other technicians, can refer to this book to troubleshoot network outages and to prevent them from recurring. The authors emphasize cost-effective remote management and dynamic setup, providing real world examples of DHCP and DDNS technologies applied to roaming users, intelligent Web browsing, software distribution, printing, PPP dial-up, and other network needs. This publication helps TCP/IP network operators establish a solid foundation for future growth without undue expense. Enterprise network staff will appreciate the sections that explore high end technologies, including Network TeleSystems' Shadow IPserver, IBM Communications Server, and UNIX platforms. All network managers should find the authors' advice on security well worth reading. This second edition updates the contents of the previous redbook to include OS/2 Warp Server for e-business with TCP/IP Version 4.21, Windows 98 and Windows 2000, and adds more information about dynamic IP configuration on AIX. It also takes a fres

This edition of the redbook will help you install, configure, administer and use IBM SecureWay Personal Communications 4.3 for Windows 95, 98 and NT, known as PCOMM. It is not a comprehensive manual about all the versions of PCOMM; it is concerned only with features that are new in Version 4.3. The book describes all the new functions of Personal Communications 4.3, from the point of view of both administrator and user. It explains how the functions work and the ways in which they can be configured to suit differing requirements. Major topics include security, which is becoming more and more important as host applications are made available on extranets or the Internet, and system management, which is provided through support of the Tivoli Management Environment. Also included is information about enhancements to PCOMM's IP and IPX connectivity, and the introduction of a Java programming interface

The IBM eNetwork Communications Suite combines the power of several successful communication software packages to provide access to corporate mainframe systems, application and mail servers, and also the Internet.
