SSH (Secure Shell) is a TCP/IP-based solution to many network security and privacy concerns. It supports secure remote logins, secure file transfer between computers, and a unique "tunnelling" capability that adds encryption to otherwise insecure network applications. Best of all, SSH is free, with feature-filled commercial versions available as well. This text covers the Secure Shell in detail for both system administrators and end users. It demystifies the SSH man pages and includes thorough c...

Linux is an operating system very similar to Unix. It can do most of what Unix and Windows NT can do only cheaper. But IT departments have been slow to adopt Linux for business use because it is "open source" technology, meaning that no one vendor like Sun or IBM or Microsoft is responsible for it. Even without IT endorsement, Linux has already made its way into most corporations and is in use - undocumented - for certain key applications. It's estimated that up to 70% of Apache web servers are...

With this practical book, you will attain a solid understanding of threads and will discover how to put this powerful mode of programming to work in real-world applications. The primary advantage of threaded programming is that it enables your applications to accomplish more than one task at the same time by using the number-crunching power of multiprocessor parallelism and by automatically exploiting I/O concurrency in your code, even on a single processor machine. The result: applications tha...

It began simply enough. A young Finnish student at the University of Helsinki named Linus Torvalds decided to develop his own computer operating system merely as a hobby. More than a decade later, this same operating system has caused nothing short of a revolution in the world of computers. Now known as Linux, Torvalds' creation was largely dismissed in the 1990s by tech pundits who claimed that it was unsuitable for the general public's computing needs. If they only knew how wrong they were! Af...

This book tells the reader how to manage a complex software development project using RCS and SCCS. The book is organized in terms of increasingly complex management problems, from simple source management, to managing multiple releases, to co-ordinating teams of developers on a project involving many files and many target platforms. Few developers use RCS or SCCS alone; most groups have written their own extensions for working with multi-person, multi-platform, multi-file, multi-release project...
