* Authored by two Fortune 100 system administrators responsible for the architecture and deployment of OpenSSH across several hundred corporate servers. * Covers commonplace yet often confusing deployment scenarios that come up daily in enterprise environments, large and small. * Focuses upon the worlds most prevalent SSH implementation, OpenSSH.

SSH, or Secure Shell, is the de facto standard among users and administrators who wish to establish secure communication between disparate networks. This book is authored by a Fortune 100 system administrator, who will provide you with a highly practical reference for configuring and deploying OpenSSH in your own environment. Some of the topics covered in this book include: OpenSSH installation and configuration, key management, secure logging, client/server architectures, and digital certificates. The author also provides you with complete deployment scenarios that arise daily in enterprise environments, both large and small.

Are you serious about network security? Then check out SSH, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, SSH eliminates several of them very effectively.Everything you want to know about SSH is in our second edition of SSH, The Secure Shell: The Definitive Guide. This updated book thoroughly covers the latest SSH-2 protocol for system administrators and end users interested in using this increasingly popular TCP/IP-based solution.How does it work? Whenever data is sent to the network, SSH automatically encrypts it. When data reaches its intended recipient, SSH decrypts it. The result is "transparent" encryption-users can work normally, unaware that their communications are already encrypted. SSH supports secure file transfer between computers, secure remote logins, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. With SSH, users can freely navigate the Internet, and system administrators can secure their networks or perform remote administration.Written for a wide, technical audience, SSH, The Secure Shell: The Definitive Guide covers several implementations of SSH for different operating systems and computing environments. Whether you're an individual running Linux machines at home, a corporate network administrator with thousands of users, or a PC/Mac owner who just wants a secure way to telnet or transfer files between machines, our indispensable guide has you covered. It starts with simple installation and use of SSH, and works its way to in-depth case studies on large, sensitive computer networks.No matter where or how you're shipping information, SSH, The Secure Shell: The Definitive Guide will show you how to do it securely.

Unlike some operating systems, Linux doesn’t try to hide the important bits from you—it gives you full control of your computer. But to truly master Linux, you need to understand its internals, like how the system boots, how networking works, and what the kernel actually does. In this completely revised second edition of the perennial best seller How Linux Works, author Brian Ward makes the concepts behind Linux internals accessible to anyone curious about the inner workings of the operating system. Inside, you’ll find the kind of knowledge that normally comes from years of experience doing things the hard way. You’ll learn: –How Linux boots, from boot loaders to init implementations (systemd, Upstart, and System V) –How the kernel manages devices, device drivers, and processes –How networking, interfaces, firewalls, and servers work –How development tools work and relate to shared libraries –How to write effective shell scripts You’ll also explore the kernel and examine key system tasks inside user space, including system calls, input and output, and filesystems. With its combination of background, theory, real-world examples, and patient explanations, How Linux Works will teach you what you need to know to solve pesky problems and take control of your operating system.

Curious about Linux, the amazing alternative operating system? Not sure which of the zillion different variations is right for you, or how to find out? How wise you are to think of Linux All-In-One Desk Reference For Dummies! Because Linux offers so many options, this book helps you narrow them down by giving you five popular Linux distributions on a DVD—Debian GNU/Linux, Fedora, openSUSE Linux, Ubuntu, and Xandros. You get everything you need to test-drive all five, including the instructions to install and use any of them. But that’s just the beginning! Linux All-In-One Desk Reference For Dummies includes eight individual minibooks, each devoted to a specific aspect of Linux: Linux Basics Linux Desktops Networking Internet Administration Security Internet Servers Programming You’ll find out how to: Understand the Linux kernel Create a network and connect a Linux PC to the Internet Use Internet services including Web, Mail, News, FTP, NFS, and DNS. Set up a Windows server using Samba Use Perl, shell, and C programming with Linux Manage system and network security and administration Work with the OpenOffice.org productivity tools and other applications that come with Linux So what are you waiting for? Linux All-In-One Desk Reference For Dummies is like having a guided tour of the wonderful world of Linux! Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.

This book shows in detail how to build enterprise-level secure, redundant, and highly scalable services from scratch on top of the open source Linux operating system, suitable for small companies as well as big universities. The core architecture presented is based on Kerberos, LDAP, AFS, and Samba. Coverage shows how to integrate web, message related, data base and other services with this backbone. This architecture provides a Single-Sign-On solution for different client platforms and can also be employed for clustering. Although it is implemented with Debian GNU/Linux, the content can be applied to other UNIX flavors.

A guide to the TCP/IP-based network security and privacy solution covers installation, configuration, maintenance, SSH server control, application tunneling, forced commands, port and agent forwarding, and troubleshooting.

Presents information on how to analyze risks to your networks and the steps needed to select and deploy the appropriate countermeasures to reduce your exposure to physical and network threats. Also imparts the skills and knowledge needed to identify and counter some fundamental security risks and requirements, including Internet security threats and measures (audit trails IP sniffing/spoofing etc.) and how to implement security policies and procedures. In addition, this book covers security and network design with respect to particular vulnerabilities and threats. It also covers risk assessment and mitigation and auditing and testing of security systems as well as application standards and technologies required to build secure VPNs, configure client software and server operating systems, IPsec-enabled routers, firewalls and SSL clients. This comprehensive book will provide essential knowledge and skills needed to select, design and deploy a public key infrastructure (PKI) to secure existing and future applications.* Chapters contributed by leaders in the field cover theory and practice of computer security technology, allowing the reader to develop a new level of technical expertise* Comprehensive and up-to-date coverage of security issues facilitates learning and allows the reader to remain current and fully informed from multiple viewpoints* Presents methods of analysis and problem-solving techniques, enhancing the reader's grasp of the material and ability to implement practical solutions
