Tcl 8.5 Network Programming. Learn Tcl and you’ll never look back when it comes to developing network-aware applications. This book is the perfect way in, taking you from the basics to more advanced topics in easy, logical steps

Piotr Beltowski, Wojciech Kocjan, Clif Flynt

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.The book explains Simple Network Management Protocol (SNMP), which is often used for monitoring and gathering information from various devices, such as routers, gateways, printers and many other types of equipment. We’ll also look at web programming in Tcl; processing the requests coming from the clients via the HTTP protocol and responding to these requests. You’ll be able to create a complete solution for creating a client-server application in Tcl.To round things off, you’ll see how to secure your networked applications, build public key infrastructure into your application and use Tcl’s safe interpreter feature to reduce risk of running code from unknown source.

Metasploit 5.0 for Beginners. Perform penetration testing to secure your IT environment against threats and vulnerabilities - Second Edition

Sagar Rahalkar

Securing an IT environment can be challenging, however, effective penetration testing and threat identification can make all the difference. This book will help you learn how to use the Metasploit Framework optimally for comprehensive penetration testing.Complete with hands-on tutorials and case studies, this updated second edition will teach you the basics of the Metasploit Framework along with its functionalities. You’ll learn how to set up and configure Metasploit on various platforms to create a virtual test environment. Next, you’ll get hands-on with the essential tools. As you progress, you’ll learn how to find weaknesses in the target system and hunt for vulnerabilities using Metasploit and its supporting tools and components. Later, you'll get to grips with web app security scanning, bypassing anti-virus, and post-compromise methods for clearing traces on the target system. The concluding chapters will take you through real-world case studies and scenarios that will help you apply the knowledge you’ve gained to ethically hack into target systems. You’ll also discover the latest security techniques that can be directly applied to scan, test, ethically hack, and secure networks and systems with Metasploit.By the end of this book, you’ll have learned how to use the Metasploit 5.0 Framework to exploit real-world vulnerabilities.

EJB 3.0 Database Persistence with Oracle Fusion Middleware 11g. This book walks you through the practical usage of EJB 3.0 database persistence with Oracle Fusion Middleware. Lots of examples and a step-by-step approach make it a great way for EJB application developers to acquire new skills

Deepak Vohra, Deepak Vohra

EJB (Enterprise JavaBeans) 3.0 is a commonly used database persistence technology in Java EE applications. EJB 3.0 has simplified the development of EJBs with an annotations-based API that eliminates the use of remote/local interfaces, home/local home interfaces, and deployment descriptors. A number of other books are available on EJB 3.0, but none covers EJB 3.0 support in Oracle Fusion Middleware 11g, which is one of the leaders in the application server market.This is the first book that covers all aspects of EJB 3.0 database persistence development using Oracle Fusion Middleware technology. It covers all the best practices for database persistence ensuring that your applications are easily maintainable. Leaving theory behind, this book uses real-world examples to guide you in building your own EJB 3.0 applications that are well integrated with commonly used Java EE frameworks.The book gets going by discussing the new features in the EJB 3.0 specification. As some readers may still be using EJB 2.0, the book explains how to convert your EJB 2.0 entity beans to EJB 3.0. It then goes on to discuss using EJB 3.0 database persistence with JDeveloper, WebLogic Server, and Enterprise Pack for Eclipse, the main Java EE components of Oracle Fusion Middleware 11g. The book also covers EJB 3.0 relationships and integrating EJB 3.0 relationships with JSF user interfaces. EJB 3.0 database persistence with some of the commonly used frameworks such as ADF Faces, AJAX, and Web Services is also discussed in the book. It uses the integrated WebLogic Server 11g in some of the chapters and the standalone WebLogic Server in other chapters. While JDeveloper is the primary Java IDE used in the book, one of the chapters is based on the Oracle Enterprise Pack for Eclipse.By the time you reach the end of this book, you will be well-versed with developing EJB 3.0 applications using the different Java EE components of Oracle Fusion Middleware 11g.
