The Tcl language and Tk graphical toolkit are simple and powerful building blocks for custom applications. The Tcl/Tk combination is increasingly popular because it lets you produce sophisticated graphical interfaces with a few easy commands, develop and change scripts quickly, and conveniently tie together existing utilities or programming libraries.One of the attractive features of Tcl/Tk is the wide variety of commands, many offering a wealth of options. Most of the things you’d like to do have been anticipated by the language’s creator, John Ousterhout, or one of the developers of Tcl/Tk’s many powerful extensions. Thus, you’ll find that a command or option probably exists to provide just what you need.And that’s why it’s valuable to have a quick reference that briefly describes every command and option in the core Tcl/Tk distribution as well as the most popular extensions. Keep this book on your desk as you write scripts, and you’ll be able to find almost instantly the particular option you need.Most chapters consist of alphabetical listings. Since Tk and mega-widget packages break down commands by widget, the chapters on these topics are organized by widget along with a section of core commands where appropriate. Contents include:

• Core Tcl and Tk commands and Tk widgets
• C interface (prototypes)
• Expect
• [incr Tcl] and [incr Tk]
• Tix
• TclX
• BLT
• Oratcl, SybTcl, and Tclodbc

What This Book Covers

Chapter 1 begins to explain basic DNS principles. It introduces essential names, for example,domain and zone, explaining the difference between them. It describes the iteration principle by which the DNS translates names to IP addresses. It presents a configuration of a resolver both for UNIX and for Windows. The end of the chapter explains name server principles and describes various name server types.
Chapter 2 is fully focused on the most basic DNS procedure, the DNS query. Through this procedure, the DNS translates names to IP addresses. In the very beginning, however, this chapter describes in detail the Resource Record structure. At the end of this chapter, many practical examples of DNS exchanges are listed.
Chapter 3 deals with other DNS procedures (DNS Extensions), i.e., DNS Update, DNS Notify, incremental zone transfer, negative caching, IPv6 Extensions, IPsec, and TSIG.
Chapter 4 talks about the DNS implementation. It is derived from its historical evolution. From the historical point of view, the oldest DNS implementation that is still sometimes used is BIND version 4. This implementation is very simple so it is suitable to describe basic principles with it. Next, the new generations of BIND are discussed followed by the Windows 2000 implementation.
Chapter 5 discusses the tools for debugging DNS such as nslookup, dnswalk, and dig, how to control a name server using the rndc program, and the common errors that might occur while configuring DNS.
Chapter 6 deals with the creation of DNS domains (domain delegation) and with the procedure of domain registration.

Book Description:

Linux can be configured as a networked workstation, a DNS server, a mail server, a firewall, a gateway router, and many other things. These are all part of administration tasks, hence network administration is one of the main tasks of Linux system administration. By knowing how to configure system network interfaces in a reliable and optimal manner, Linux administrators can deploy and configure several network services including file, web, mail, and servers while working in large enterprise environments.

Starting with a simple Linux router that passes traffic between two private networks, you will see how to enable NAT on the router in order to allow Internet access from the network, and will also enable DHCP on the network to ease configuration of client systems. You will then move on to configuring your own DNS server on your local network using bind9 and tying it into your DHCP server to allow automatic configuration of local hostnames. You will then future enable your network by setting up IPv6 via tunnel providers.

Moving on, we’ll configure Samba to centralize authentication for your network services; we will also configure Linux client to leverage it for authentication, and set up a RADIUS server that uses the directory server for authentication.

Toward the end, you will have a network with a number of services running on it, and will implement monitoring in order to detect problems as they occur.

What you will learn

• Route an IPv6 netblock to your local network
• Modify your named instance to support setting hostnames for your IPv6 addresses
• Use SSH for remote console access
• Configure NGINX with TLS
• Secure XMPP with TLS
• Leverage iptables6 to firewall your IPv6 traffic
• Configure Samba as an Active Directory compatible directory service

Book Description:

This book is the ideal introduction to using OpenLDAP for Application Developers and will also benefit System Administrators running OpenLDAP. It prepares the reader to build a directory using OpenLDAP, and then employ this directory in the context of the network, taking a practical approach that emphasizes how to get things done. On occasion, it delves into theoretical aspects of LDAP, but only where understanding the theory helps to answer practical questions. The reader requires no knowledge of OpenLDAP, but even readers already familiar with the technology will find new things and techniques. The target audience will require basic Linux system administration knowledge, but no prior knowledge of LDAP or OpenLDAP is assumed. If you are web savvy and are interested in using OpenLDAP for web applications and services like client interaction then this is the book for you.

Book Description:

Reveals and illustrates the awesome power and flexibility of the command line, and the design and usage philosophies that support those traits. This understanding of how to extract the most from the Linux command line can help you become a better SysAdmin. Understand why many things in the Linux and Unix worlds are done as they are, and how to apply the Linux Philosophy to working as a SysAdmin.

The original Unix/Linux Philosophy presented foundational and functional tenets – rules, guidelines, and procedural methods – that worked well. However, it was intended for the developers of those operating systems. Although System Administrators could apply many of the tenets to their daily work, many important tenets were missing.

Over the years that David Both has been working with Linux and Unix, he has formulated his own philosophy – one which applies more directly to the everyday life of the System Administrator. This book defines a philosophy, and then illuminates the practical aspects of that philosophy with real-world experiments you can perform. Inspired by David’s real mentors, and dedicated to them, The Linux Philosophy for System Administrators is a mentor to SysAdmins everywhere; remember – “If you fail you learn.”

What You Will Learn

• Apply the Linux philosophy to working as a SysAdmin
• Unlock the power of the knowledge you already have
• Fully understand and access the vast power of the command line
• Review the power of Linux as a function of the philosophies that built it

Who This Book Is For

If you want to learn the secrets that make the best Linux SysAdmins powerful far beyond that of mere mortals; if you want to understand the concepts that unlock those secrets; if you want to be the SysAdmin that everyone else turns to when the bytes hit the fan – then this book is for you.

Content Management Servers (CMS) have been around for a very long time, both proprietary and open source ones, but there has not been a standard way of talking to them until recently. The Content Management Interoperability Services (CMIS) standard provides both an application programming interface and a search language (based on SQL-92). Alfresco CMIS implementation is the basis for many existing CMIS applications, and you can use CMIS too to integrate your application with Alfresco.

Alfresco CMIS is a practical, hands-on guide that provides you with a number of clear step-by-step exercises that will help you take advantage of the real power of CMIS, and give you a good foundation in using it via HTTP/XML, Java, or scripting.It starts off with an introduction to the CMIS standard, in order to update you on the service API, object model, and query language.

The first part of the book explains how to use the service API with HTTP and XML/JSON; this is done in order to show that any library, system, or tool that can make HTTP calls and parse XML or JSON, is able to talk to a content management server that supports CMIS. Next, you learn to demonstrate how a higher abstraction library can be used to talk to a CMIS server in an easy way, hiding some of the complexities of the API using the OpenCMIS Java library. Since most of the applications that are built today are web applications, the book teaches readers how CMIS can be used from JavaScript and Groovy; enterprise application integration, taking Drupal and Mule as references.

Finally, you will learn how to talk to Alfresco Cloud service via CMIS!

Who This Book Is For

If you are a developer who wants to learn how to build applications that talk to content management servers in a standard way using CMIS, this book is ideal for you. It will be helpful if you have a bit of programming experience, although it is not necessary.

Book Description:

Microsoft Windows is one of the two most common OS and managing its security has spawned the discipline of IT security. Kali Linux is the premier platform for testing and maintaining Windows security. Kali is built on the Debian distribution of Linux and shares the legendary stability of that OS. This lets you focus on using the network penetration, password cracking, forensics tools and not the OS.

This book has the most advanced tools and techniques to reproduce the methods used by sophisticated hackers to make you an expert in Kali Linux penetration testing. First, you are introduced to Kali’s top ten tools and other useful reporting tools. Then, you will find your way around your target network and determine known vulnerabilities to be able to exploit a system remotely. Next, you will prove that the vulnerabilities you have found are real and exploitable. You will learn to use tools in seven categories of exploitation tools. Further, you perform web access exploits using tools like websploit and more. Security is only as strong as the weakest link in the chain. Passwords are often that weak link. Thus, you learn about password attacks that can be used in concert with other approaches to break into and own a network. Moreover, you come to terms with network sniffing, which helps you understand which users are using services you can exploit, and IP spoofing, which can be used to poison a system’s DNS cache. Once you gain access to a machine or network, maintaining access is important.

Thus, you not only learn penetrating in the machine you also learn Windows privilege’s escalations. With easy to follow step-by-step instructions and support images, you will be able to quickly pen test your system and network.
