Download or read book VPNs Illustrated written by Jon C. Snader and published by Addison-Wesley Professional. This book was released on 2015-01-09 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtual private networks (VPNs) based on the Internet instead of the traditional leased lines offer organizations of all sizes the promise of a low-cost, secure electronic network. However, using the Internet to carry sensitive information can present serious privacy and security problems. By explaining how VPNs actually work, networking expert Jon Snader shows software engineers and network administrators how to use tunneling, authentication, and encryption to create safe, effective VPNs for any environment. Using an example-driven approach, VPNs Illustrated explores how tunnels and VPNs function by observing their behavior "on the wire." By learning to read and interpret various network traces, such as those produced by tcpdump, readers will be able to better understand and troubleshoot VPN and network behavior. Specific topics covered include: Block and stream symmetric ciphers, such as AES and RC4; and asymmetric ciphers, such as RSA and EIGamal Message authentication codes, including HMACs Tunneling technologies based on gtunnel SSL protocol for building network-to-network VPNs SSH protocols as drop-in replacements for telnet, ftp, and the BSD r-commands Lightweight VPNs, including VTun, CIPE, tinc, and OpenVPN IPsec, including its Authentication Header (AH) protocol, Encapsulating Security Payload (ESP), and IKE (the key management protocol) Packed with details, the text can be used as a handbook describing the functions of the protocols and the message formats that they use. Source code is available for download, and an appendix covers publicly available software that can be used to build tunnels and analyze traffic flow. VPNs Illustrated gives you the knowledge of tunneling and VPN technology you need to understand existing VPN implementations and successfully create your own.

Download or read book The Supermen written by Charles J. Murray and published by John Wiley & Sons. This book was released on 1997-01-18 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SUPERMEN "After a rare speech at the National Center for Atmospheric Research in Boulder, Colorado, in 1976, programmers in the audience had suddenly fallen silent when Cray offered to answer questions. He stood there for several minutes, waiting for their queries, but none came. When he left, the head of NCAR's computing division chided the programmers. 'Why didn't someone raise a hand?' After a tense moment, one programmer replied, 'How do you talk to God?'" -from The SUPERMEN The Story of Seymour Cray and the Technical Wizards behind the Supercomputer "They were building revolutionary, not evolutionary, machines. . . . They were blazing a trail-molding science into a product. . . . The freedom to create was extraordinary." -from The Supermen In 1951, a soft-spoken, skinny young man fresh from the University of Minnesota took a job in an old glider factory in St. Paul. Computer technology would never be the same, for the glider factory was the home of Engineering Research Associates and the recent college grad was Seymour R. Cray. During his extraordinary career, Cray would be alternately hailed as "the Albert Einstein," "the Thomas Edison," and "the Evel Knievel" of supercomputing. At various times, he was all three-a master craftsman, inventor, and visionary whose disdain for the rigors of corporate life became legendary, and whose achievements remain unsurpassed. The Supermen is award-winning writer Charles J. Murray's exhilarating account of how the brilliant-some would say eccentric-Cray and his gifted colleagues blazed the trail that led to the Information Age. This is a thrilling, real-life scientific adventure, deftly capturing the daring, seat-of-the-pants spirit of the early days of computer development, as well as an audacious, modern-day David and Goliath battle, in which a group of maverick engineers beat out IBM to become the runaway industry leaders. Murray's briskly paced narrative begins during the final months of the Second World War, when men such as William Norris and Howard Engstrom began researching commercial applications for the code-breaking machines of wartime, and charts the rise of technological research in response to the Cold War. In those days computers were huge, cumbersome machines with names like Demon and Atlas. When Cray came on board, things quickly changed. Drawing on in-depth interviews-including the last interview Cray completed before his untimely and tragic death-Murray provides rare insight into Cray's often controversial approach to his work. Cray could spend exhausting hours in single-minded pursuit of a particular goal, and Murray takes us behind the scenes to witness late-night brainstorming sessions and miraculous eleventh-hour fixes. Cray's casual, often hostile attitude toward management, although alienating to some, was more than a passionate need for independence; he simply thought differently than others. Seymour Cray saw farther and faster, and trusted his vision with an unassailable confidence. Yet he inspired great loyalty as well, making it possible for his own start-up company, Cray Research, to bring the 54,000-employee conglomerate of Control Data to its knees. Ultimately, The Supermen is a story of genius, and how a unique set of circumstances-a small-team approach, corporate detachment, and a government-backed marketplace-enabled that genius to flourish. In an atmosphere of unparalleled freedom and creativity, Seymour Cray's vision and drive fueled a technological revolution from which America would emerge as the world's leader in supercomputing.
