REF:http://www.linuxhq.com/guides/index.html

Linux Getting Started Guide
Linux Installation and Getting Started is an installation and new-user guide to the Linux system. Linux is a free clone of the UNIX operating system developed for 80386 and 80486 machines. This book describes how to obtain and install Linux on your system, as well as how to start using it. Information on configuration of X-Windows, basic system administration, and much more is included.

System Administrator's Guide
This is a manual and tutorial for keeping a Linux system up and running. This version is not finished, but the finished version is supposed to cover all the central topics except networking (for which see the Linux Network Administrators' Guide). This manual does not try to be a reference manual, or a manual to all the different programs that a system administrator might use. Separate documentation (such as man pages) exist for those.

Network Administrator's Guide
This guide provides an overview to setting up and running a network using Linux. It covers such topics as, UUCP, TCP, Security, Hardware configuration and many other useful topics.

Linux Programmer's Guide
This guides covers general programming hints and HOW-TO's for programming in the Linux environment. Topics include Unix pipes, IPC, Sound programming, character based app development, I/O ports, and porting applications to Linux from other operating systems.

Linux User's Guide
Anyone who has Linux, the free Unix clone written by Linus Torvalds , on their PC but doesn't know what to do next should read this book. In this book, we'll cover most of the basic Unix commands, as well as some of the more advanced ones. We'll also talk about GNU Emacs , a powerful editor, and several other large Unix applications.

The Linux Kernel
The kernel is at the heart of the Operating System. This book is a guide to how the kernel fits together, how it works; a tour of the kernel.

The Linux Kernel Module Programming Guide
This document is for people who want to write kernel modules.

Here are some good resources if you are interested in kernel programming

REF:http://www.linuxhq.com/lkprogram.html#filesystem

Various
Kernel Analysis HOWTO This document tries to explain some things about the Linux Kernel, such as the most important components, how they work, and so on. This HOWTO should help prevent the reader from needing to browse all the kernel source files searching for the "right function", declaration, and definition, and then linking each to the other.	The Linux Kernel This book is for Linux enthusiasts who want to know how the Linux kernel works. It is not an internals manual. Rather it describes the principles and mechanisms that Linux uses; how and why the Linux kernel works the way that it does.
Kernel Newbies A good place to start if you are new to kernel programming. They also run the IRC channel #kernelnewbies which you can reach at irc.kernelnewbies.org.	Kernel Traffic Kernel Traffic is a weekly summary of what is going on in the linux-kernel mailing-list. Very nice if you want to see where development is going, but dont wish to subscribe to that mailing-list (which is very high-traffic)
Official Linux Kernel-Docs Various documents on kernel programming	Unreliable Guide To Hacking The Linux Kernel This document describes the common routines and general requirements for kernel code: its goal is to serve as a primer for Linux kernel development for experienced C programmers.
Linux 2.4.x Initialization for IA-32 This document is a description of the Linux 2.4 kernel initialization sequence on IA-32 processors.	Linux Kernel 2.4 Internals Introduction to the Linux 2.4 kernel.
Cross-Referencing Linux Easy browsing of the linux kernel code	User-mode Linux User-Mode Linux is a safe, secure way of running Linux versions and Linux processes. Run buggy software, experiment with new Linux kernels or distributions, and poke around in the internals of Linux, all without risking your main Linux setup.
Yet Another HOWTO Add a Syscall to Linux This is a short, quick example of how to add a system call to Linux for x86. This example is specific to Linux version 2.4.18 but it should be easy to modify the patch to work with other kernel versions.	Linux System Call Table This page lists the system calls for the Linux 2.2 kernel. It could also be thought of as an API for the interface between user space and kernel space.
Filesystems
The Second Extended Filesystem Covers Linux filesystems history, ext2 features, design, physical structure on disk etc. It is written by three of the top ext2 hackers, and is a must read!	Overview of the Virtual File System Brief introduction to the Linux Virtual File System. What is it, how it works, operations taken when opening a file or mounting a file system and description of important data structures explaining the purpose of each of their entries.
A Dual-Disk File System: ext4 This paper presents the design and implementation of a Unix-compatible file system, ext4, which uses two disk partitions to store its data. One partition is used exclusively for directory-related information, and one partition for ordinary files.
Module programming
Linux Kernel Module Programming A bit dated, but an excellent guide for anyone wishing to get started on kernel module programming.	(nearly) Complete Linux Loadable Kernel Modules Another guide on kernel module programming, with focus on security
Devices
Linux Device Drivers, 2nd Edition Online version of an excellent book by Alessandro Rubini & Jonathan Corbet on how to write device drivers.	Writing a Linux device driver Quick primer on device driver programming.
Linux SCSI Generic (sg) HOWTO This HOWTO describes the SCSI Generic driver (sg) found in the Linux 2.4 production series of kernels.	Programming Guide for Linux USB Device Drivers This document should give detailed information about the current state of the USB subsystem and its API for USB device drivers. You will learn about different types of devices and their properties. Going into detail you will see how USB devices communicate on the bus. There is an overview of the Linux USB subsystem and the device driver framework. Then the API and its data structures will be explained step by step.
Networking
Linux netfilter Hacking HOWTO This document describes the netfilter architecture for Linux, how to hack it, and some of the major systems which sit on top of it, such as packet filtering, connection tracking and Network Address Translation.	The journey of a packet through the linux 2.4 network stack This document describes the journey of a network packet inside the linux kernel 2.4.x. This has changed drastically since 2.2 because the globally serialized bottom half was abandoned in favor of the new softirq system.
Netfilter connection tracking and nat helper modules This document gives a brief description how to write netfilter connection tracking helper and nat helper modules. Netfilter is the packet filtering / NAT infrastructure provided by the Linux 2.4.x kernel.	skb - Linux network buffers Short description about the linux network buffers (skb's)
Building into the Linux Network Layer Phrack article that points out interesting things that can be done using Kernel Modules in the Network Layer. Like most Phrack articles it is very interesting reading, especially if you are interested in security.
Security
Weakening the Linux Kernel Yet another excellent Phrack article. This one is about modifying system calls, Kernel Module hiding etc. Interesting security issue, if your kernel allows module usage. Mainly focus on the 2.0.x kernel series	Hardening the Linux Kernel This article covers a few areas of potential insecurity in the Linux OS and attempts to improve upon them. It contains several security related kernel patches for the 2.0.x kernels.
Writing Linux Kernel Keylogger This article begin by describing how the linux keyboard driver work, and discusses methods that can be used to create a kernel based keylogger. It then presents a smart, kernel-based linux keylogger.
Memory Management
Linux MM This site is supposed to provide full documentation on the Linux MM subsystem and to give a good overview of what's happening in the Linux MM community.	Rik van Riel lectures Very good texts on various aspects of memory management
Linux 2.4 Virtual Memory Overview On this page you can find some studies of Linux 2.4 VM system. This page was created to help us out to visualize VM system better.	Outline of the Linux Memory Management System These pages contain notes on the Linux memory-management system.

Install DotNetNuke 4.4.0 on Windows XP

Steps:

Precondition: Your box has been installed the VS 2005 and Sql Server 2005
Download a copy of DotNetNuke 4.4.0 source pack from its government site.
Config IIS

Extract the the source pack:DotNetNuke_4.4.0_Source to C:\DotNetNuke\.
Setup a Virtual directory with name DotNetNuke from IIS, which will point to c:\DotNetNuke\WebSite\
Set the the DotNetNuke site: execute permissions-> Scripts and Exectutables, Asp.Net version at the ASP.NET Tab -> 2.0.50727
Enable the Enable-Default-Document setting on the Documents tab and make sure the the Default.aspx is in the list.

Configure Sql Server 2005

Create a new data base named as DotNetNuke
Create a new sql server login user: dnn
Add the dnn user as the dbowner of DotNetNuke data base

Configure Web.Config

At the root of the site (C:\DotNetNuke\Website), rename the release.config as Web.config
Modify the Connection string of web.config file as following:

In connectionstring section:
<connectionStrings>


<add name="SiteSqlServer" connectionString ="Server=(local);Database=DotNetNuke;uid=dnn;pwd=dnn;" providerName="System.Data.SqlClient " />
</ connectionStrings>
In appsettings section:



<add key="SiteSqlServer" value="Server=(local);Database=DotNetNuke;uid=dnn;pwd=dnn;" />

Set site root access permission

First enable the Enable-Simple-File-Sharing setting of XP
Add the full control permission of ASP.NET user on the site root folder:C:\DotNetNuke\Website and inherit the setting to all its child files and folders.

Start to install

Access the site url:http://localhost/dotnetnuke/
You will see the installation successfully message after a few minutes.

Exceptions encountered during installation:

Error (HTTP 403 Forbidden) :

Detail:

This error (HTTP 403 Forbidden) means that Internet Explorer was able to connect to the website, but it does not have permission to view the webpage.
For more information about HTTP errors, see Help.

Solution:

Make sure the Enable-Default-Document setting is enabled on the Documents tab of IIS web site property page and the the Default.aspx is in the document list.

Access to the path 'C:\DotNetNuke\Website\web.config' is denied.

Detail:

DotNetNuke Configuration Error
Access to the path 'C:\DotNetNuke\Website\web.config' is denied.

DotNetNuke has extensive file upload capabilities for content, modules, and skins. These features require custom security settings so that the application is able to create and remove files in your website.

Using Windows Explorer, browse to the root folder of the website ( C:\DotNetNuke by default ). Right-click the folder and select Sharing and Security from the popup menu ( please note that if you are using Windows XP you may need to Enable Simple File Sharing before these options are displayed ). Select the Security tab. Add the appropriate User Account and set the Permissions.

If using Windows 2000 - IIS5

the {Server}\ASPNET User Account must have Read, Write, and Change Control of the virtual root of your website.

If using Windows 2003 - IIS6

the NT AUTHORITY\NETWORK SERVICE User Account must have Read, Write, and Change Control of the virtual root of your website.

Solution:

Please check the access permission of the root of the site.
Especially the Asp.Net user should have full control of the root folder and all its sub folders and files.
Especially, only select the second to replace all permission of children.

个人发展的新想法

我做技术也许会成为有名的专家，但是难道我不能再做一些切实能给人们生活带来改善的事情，例如修灯泡！

把技术当成业余爱好吧！

把自己放到社会中最需要人才的地方吧，即使是收垃圾的工作。
