Book Description

Tcl (Tool Command Language) is a very powerful and easy to learn dynamic programming language, suitable for a very wide range of uses. Tcl is regarded as one of the best-kept secrets in the software industry. This book gives you a hands-on experience on Tcl, helping you develop network-aware applications using this mature yet evolving language.

This book shows you how to create network-aware applications with Tcl language. Packed with practical examples, the book not only takes you through the implementation of network protocols in Tcl, but also key aspects of Tcl programming.

The book starts with the basic element of Tcl programming as we take a look at the syntax and fundamental commands of the language. To get us ready for network programming, we look at important Tcl features such as object-oriented programming, accessing files, packaging in TCL, event driven programming, and multithreaded applications. To create standalone single-file executable applications with Tcl we take a look at the Starpack technology, and ensure that we’ll be able to create robust applications with a thorough coverage of troubleshooting and debugging Tcl applications.

The book is really about network programming, and it will not let you down with its deep coverage of these topics. Of course we look at protocols, but there are plenty of practical examples to keep things moving along. We start with the TCP and UDP protocols, and look at some other protocols to see examples of synchronizing time with other servers, querying user information and authenticating users over LDAP and performing DNS queries.

Book Description

Now updated for Windows Server 2008 and Windows Vista, this guide delivers in-depth technical information on Internet Protocol version 6 (IPv6). IPv6 greatly improves on IPv4, the current protocol, by vastly increasing the number of available addresses and by adding enhancements for security, multimedia traffic management, routing, and network configuration. Written by a popular author and networking expert, this reference details the protocol, from its features and benefits to its packet structure and protocol processes. It also describes how to migrate to IPv6-based internetworking, with tips about coexistence with IPv4-based systems, DHCP, DNS, and routing infrastructure. It discusses how IPv6 is supported by the Windows Server 2008 family of operating systems and Windows Vista. Includes companion CD with fully searchable eBook and other references.

Book Description

Competent system administrators know their success hinges upon being able to perform often tedious tasks with rigor and punctuality. Such metrics are often achieved only by instituting a considerable degree of automation, something that has become even more crucial as IT environments continue to scale both in terms of size and complexity. One of the most powerful system administration tools to be released is Puppet, a solution capable of automating nearly every aspect of a system administrator’s job, from user management, to software installation, to even configuring server services such as FTP and LDAP.

Pulling Strings with Puppet: Configuration Management Made Easy is the first book to introduce the powerful Puppet system administration tool. Author James Turnbull will guide you through Puppet’s key features, showing you how to install and configure the software, create automated Puppet tasks, known as recipes, and even create reporting solutions and extend Puppet further to your own needs. A bonus chapter is included covering the Facter library, which makes it a breeze to automate the retrieval of server configuration details such as IP and MAC addresses.
What you’ll learn

• Properly install and configure Puppet in order to begin immediately maximizing its capabilities.
• Create reporting solutions to more easily monitor automated outcomes.
• Extend Puppet to perform tasks that are capable of suiting your organization’s specific needs.
• Use Facter to query server operating systems for key data such as IP addresses, server names, and MAC addresses. Download Now »
