Rebuilding failed Linux software RAID
|
| |
Recently I had a hard drive fail. It was part of a Linux software RAID
1 (mirrored drives), so we lost no data, and just needed to replace
hardware. However, the raid does requires rebuilding. A hardware array
would usually automatically rebuild upon drive replacement, but this
needed some help.... more »

Linux Networking
|
| |
This tutorial covers TCP/IP networking and system configuration
basics. Linux can support multiple network devices. The device names
are numbered and begin at zero and count upwards. For example, a
computer running two ethernet cards will have two devices labeled /dev/
eth0 and /dev/eth1. Linux network configuration, management,... more »

Running MS Office and IE on Linux
|
| |
Wine began its life in 1993 as a way to run Windows 3.1 applications
in Linux. Wine may well have had the longest beta period in history at
15 years, however version 1.0 was recently released in June 2008.
In this article, I show you how to install Wine, Microsoft Office
2003, and Internet Explorer using my Red Hat derivative system (CentOS... more »

Using Software RAID-1 with FreeBSD
|
| |
Have you ever needed a software RAID solution for a low-end server
install? Perhaps you've wanted your workstation to take advantage of
the redundancy provided by a disk mirror without investing in a
hardware RAID controller. Has a prior painful configuration experience
turned you off software RAID altogether on Unix systems?... more »

POSIX APIs and System Calls
Let's start by stressing the difference between an application
programmer interface (API) and a system call. The former is a function
definition that specifies how to obtain a given service, while the
latter is an explicit request to the kernel made via a software
interrupt.... more »

System Call Handler and Service Routines
|
| |
When a User Mode process invokes a system call, the CPU switches to
Kernel Mode and starts the execution of a kernel function. As we will
see in the next section, in the 80 x 86 architecture a Linux system
call can be invoked in two different ways. The net result of both
methods, however, is a jump to an assembly language function called... more »

| |
By Dan Ragle
From time to time, even the most experienced programmers get stuck.
Whether the source of the blockage is a function call or included
module that the programmer isn't fully acquainted with, problems
related to the deployment of a working script on a new operating
system (possibly with a different version of the Perl interpreter), or... more »
