As the popularity of the Linux system continues to grow, the interest in writing Linux device drivers steadily increases. Most of Linux is independent of the hardware it runs on, and most users can be (happily) unaware of hardware issues. But, for each piece of hardware supported by Linux, somebody somewhere has written a driver to make it work with the system. Without device drivers, there is no functioning system. Device drivers take on a special role in the Linux kernel. They are distinct 'black boxes' that make a particular piece of hardware respond to a well-defined internal programming interface; they hide completely the details of how the device works. User activities are performed by means of a set of standardized calls that are independent of the specific driver; mapping those calls to device-specific operations that act on real hardware is then the role of the device driver. This programming interface is such that drivers can be built separately from the rest of the kernel, and 'plugged in' at runtime when needed. This modularity makes Linux drivers easy to write, to the point that there are now hundreds of them available.

FreeBSD Handbook

The FreeBSD newcomer will find that the first section of this book guides the user through the FreeBSD installation process and gently introduces the concepts and conventions that underpin UNIX. Working through this section requires little more than the desire to explore, and the ability to take on board new concepts as they are introduced. Once you have traveled this far, the second, far larger, section of the Handbook is a comprehensive reference to all manner of topics of interest to FreeBSD system administrators. Some of these chapters may recommend that you do some prior reading, and this is noted in the synopsis at the beginning of each chapter.

UNIX System Calls and Subroutines using C.

DB2 for Linux on iSeries: Implementation Guide

This redbook will help administrators and developers of DB2 UDB for Linux on iSeries. Some of the information provided in this redbook should be helpful for IT managers or decision makers to consider the advantages and disadvantages between the DB2 products offerings for either OS/400 or Linux on iSeries.

Linux on zSeries: Fibre Channel Protocol Implementation Guide

This IBM® Redbook discusses Fibre Channel Protocol (FCP) implementation for Linux® servers running on IBM eServer® zSeries® servers. With FCP support, Linux for zSeries can access industry-standard SCSI devices in a Storage Area Network (SAN). Using the SCSI IPL feature, Linux servers running under z/VM® or in an LPAR can now boot from FCP-attached SCSI disks. In addition, Linux servers can take advantage of the performance and high-availability benefits offered by multipath access to SCSI disks.

Linux Network Administrator's Guide, 2nd Edition

As it is the result of a concerted effort of programmers around the world, Linux wouldn't have been possible without the global network. So it's not surprising that in the early stages of development, several people started to work on providing it with network capabilities. A UUCP implementation was running on Linux almost from the very beginning, and work on TCP/IP-based networking started around autumn 1992, when Ross Biro and others created what has now become known as Net-1.

Securing And Optimizing Linux: Red Hat Edition |

This book is intended for a target audience of technical and system administrators who manage Linux servers, but it also includes enough material for home users and others. It discusses how to install and setup a Red Hat Linux Server with all the necessary security and optimization for a high performance Linux specific machine. Since we speak of optimization and security configuration, we have used only source distribution (tar.gz) programs; the most available type for critical server software, like Apache, BIND/DNS, Samba, Squid, OpenSSL etc. Source packages give us fast upgrades, security updates when necessary, and a better compilation, customization, and optimization option for our specific machines that often we can't have with RPM packages.
