10 free GNU/Linux Administration Books
Linux based distributions have a lot of different administration options and privilege options, Books listed here will help you with administrations privilege for different distributions debian, fedora, redhat, ubuntu, gentoo, opensuse, mandriva, …..
Also other books for security administrations, and files system directory hierarchy, software help you to secure you system, securing VPN servers,…
## so here we go…
This documentation will attempt to summarize the installation and configuration, as well as the day-to-day administrative and maintenance procedures that should be followed to keep a Linux-based server or desktop system up and running. It is geared to an audience of both corporate as well as home users. It is not intended to be a full overview of Unix operations, as there are several good texts available as well as on-line documentation which can be referred to in cases where more detailed information is required.
The Linux System Administrator’s Guide, describes the system administration aspects of using Linux. It is intended for people who know next to nothing about system administration (those saying “what is it?”), but who have already mastered at least the basics of normal usage. This manual doesn’t tell you how to install Linux; that is described in the Installation and Getting Started document. See below for more information about Linux manuals.
The filesystem standard has been designed to be used by Unix distribution developers, package developers, and system implementors. However, it is primarily intended to be a reference and is not a tutorial on how to manage a Unix filesystem or directory hierarchy.
There are numerous definitions for “computer security”, and most of them are correct. Essentially computer security means enforcement of usage policies, this must be done since people and software have flaws that can result in accidents, but also because someone may want to steal your information, use your resources inappropriately or simply deny you the use of your resources.
This manual assumes the reader is familiar with using a Unix system and/or understands Debian User Reference Manual. Additional reading for System Administrator is Debian GNU/Linux Network Administrator’s Manual. Both of these are available from the Debian Documentation Project. Another useful book is “Linux System Administrator’s Guide” by Lars Wirzenius, available from Linux Documentation Project, http://metalab.unc.edu/LDP/ .
The target audience of the book is anyone who wants to deepen their understanding of how computer systems work, as well as anyone who is likely to become involved with the technical aspects of computer intrusion or system analysis. These are not only system administrators, incident responders, other computer security professionals, or forensic analysts, but also anyone who is concerned about the impact of computer forensics on privacy.
Call it the Linux fallacy. It’s the conventional wisdom that says Linux/UNIX gives you lots of power and reliability in exchange for far more complex and costly systems management. But in fact Linux/UNIX shouldn’t be a tradeoff–as long as you also implement a set of proven best practices.
The GNU/Linux systems have reached an important level of maturity, allowing to integrate them in almost any kind of work environment, from a desktop PC to the sever facilities of a big company.
In the course Systems Administration. It is an attempt to give you an overview of the course and more importantly of computing, Linux and Systems Administration.
Many students commented that they felt lost in the detail of Linux without having an overall picture of how it fits together. Hopefully this chapter will go some way towards solving this problem, and will provide some sort of small map and compass so you have an idea of where you are and where you are going.
The aim of this book is to get you up to speed with GNU/Linux and to deliver a fun and productive environment. It guides you through the many different regions of a GNU/Linux system with a focus on getting your desktop environment to do what you want it to do. It is comprehensive with basic support for the user who installs and maintains the system themselves (whether in the home, office, club, or school). It provides insights and step-by-step procedures that deal with specific tasks in setting your system up and maintaining it. The book covers many of the core features of a GNU/Linux system and you will gain the knowledge to enjoy and use one of the most comprehensive and useful developments in the history of computing.
After you installed the new version, you maybe will say ” damn where is my bookmark !!!!? ” you forget it with old version usually happen :(
so, Before upgrading to Ubuntu 10.04 LTS which will release on April 29, their are 5 things recommended to do with the distribution you already have. whatever is the distributions is ubuntu 9.10, older versions, or other distribution.
1. Bookmark ” Favorite “ Backup
Most users using Firefox web browser, Google Chrome, Chromium ” based web browser on chrome ” , Opera, …
go to bookmarks then organize bookmarks then you will find export bookmarks. I recommend to export it as HTML file, to easily use it on any other web browser.
also you can export addons if you want. this applications is recommend to backup addons ” FEBE ”
Go to tools, then bookmark manager, then press export it will export it as HTML .
Go to Bookmark, then book mark manager, export it as well.
2. Evolution mail, Thunderbird Backup
If you want to keep your saved messages, you can easily backing it up. go to file, then backup options it will back all messages on archiving file I believe it tar.gz
3. Backup installed packages, and specific file on file system directory.
Many file you may be forget for your webcam, documents files, multimedia files, ….
4. Backup Compiz Fusion
If you are using Compiz fusion make sure you backed up your compiz fusion profile, to easily get same look next time you are going to use compiz.
5. Time to destroy Ubuntu
install any package you didn’t want to try it with this version just for fun. install extra compiz fusion plugin till message comes up telling you ” you have serious kernal error you have to restart ” , share with us what you will do with your own release before installing the new release.
webcam applications for capture photos, videos, multiple photos, and security cameras
One of the most common application located on gnome project, first it was written by google summer code project. really liked effects you can add using cheese ” noir, edge,warp,dice,hulk,….
also you can use this applications for talking multiple photos or videos, customize to specific resolution you want, working in many different distributions you can find many download options for debian based distributions, fedora, ubuntu, mint, …..
2. Camera Monitor
simple tool notify you if your camera is on or off. designed to work on gnome desktop work as well on KDE and Xfce
simply you can install it by terminal
sudo apt-get install cameramonitor
camorama is a program i wrote to learn gtk and v4l. as you can see, i am still learning . it is pretty simple at the moment, and i hope to make it much more complete. i also plan to make it more generic, as i initially wrote it with only my own creative webcam 3 in mind. hopefully it will work with other cameras. i will test on anything i can get my hands on, but that might take a while. right now you can change the video settings using the gui and apply some crappy filters i wrote to mess around with. it runs at a reasonable speed, but i would like to get the fps up as high as possible. still figuring that out. as for requirements, you will need at least gnome 2 and v4l. i haven’t used anything else crazy, and that should do it.
4. Gnome Security Camera “Gspy”
Gspy retrieves images from a video4linux device and processes these into a daily mpeg movie on the disk drive. Each image is recorded with a time stamp to insure accurate real world correlation. Special motion detection algorithms are used to reduce the size of the daily movies by eliminating pictures with similar content as well as the normal compression obtained via the mpeg process. The result is a time lapse video per day with nonlinear time compression using only the images of interest. This program will only run on Linux machines which support a video4linux-device in 640×480 capture size. This software has been tested with the 2.4.0-test1 kernel, 2.4.0-test4 and the 2.2.16 kernel with the usb backport patch. You should have the Berkeley MPEG Tools installed if you wish to generate the MPEG files. Gspy can be used without the MPEG tools, as it will fill a directory with jpg images that can be processed or viewed at a later time. Versions from 0.1.6 include a user defined command that is executed on each alarm. This command string can include a token(s) “%f%” that will get replaced with the alarm picture filename. Typical uses would be to copy the alarm picture to a remote site using ftp or scp, email the picture to someone, play a sound annoucement… “Step away from the keyboard!”, turn on lights using a parallel port or X10 interface, or ???. Have FUN
My favorite webcam application for KDE, support many webcams, able to capture photos, videos, multiple photos. you can easily share your photos and videos directly from the application to facebook and twitter.
that’s it for now.
so here we go,
Ubuntu 10.04 LTS Beta 2 review
Installed on virtual machine “sun virtualbox” application with this Hardware specifications:
- single core processor 2.1 GHz
- 512 MB of ram
- 12 MB of video memory
# Installation Process
boot it first time as live session it was working good, after the installation it was working super fast really good.
after the installation it boot super fast, really impressed with booting time about 9 second booting time at first time booting, usually any operating system after the installation it boot really quick but after the installing any extra application you their will be some lagging time to boot up.
Their is not a big difference between Beta 1 and Beta 2 themes, both of them looks the same but at bug report their a lot of reported bugs on radiance theme fixed on ubuntu 10.04 beta2
same main installed packages for applications.
Yahoo still the default search engine on firefox instead of Google search engine. with firefox version 3.6.3, it’s up to you can change the search engine later firefox options.
using last version of Gnome so far ” Gnome 2.30″ , Linux kernel v 2.6.32
security issues fixed, improvement on ubuntu one, ubuntu enterprise cloud, new default open source driver for nvidia hardware
I really like the new version of nautilus comes with Gnome 2.30 if you are not familiar with nautilus and gnome 2.30 visit this link
really like the splitting view on windows, split view come really handy on to open to directory side by side with difference icon view really good.
To activate split mode on opened windows press F3 or go to view menu and select it.
also you can drag and drop folders and files split view.
same new features included with ubuntu 10.04 beta 2 with menus and right click menu for copying files to and moving to.
Awesome booting time
Gnome 2.30 desktop really good with a lot of new features.
Ambiance and Radiance looks really good themes
none, with me so far working really good I don’t have any problems, also thinking to install it as default distribution.
and we waiting for ubuntu 10.04 LTS final version April 29th 2010 :)
Give it a try, as usual please report any bugs you got,
peace out :)
Common applications installed using synaptic package manager already installed by referring from default repositories added on ubuntu 9.10 or any other version it’s the same way to add extra repositories for other distributions such as ubuntu 10.04 LTS beta 1
Default repositories on ubuntu monitored by ubuntu community, so in this post i will show you how to add extra repositories for ubuntu 9.10 and 10.04 LTS beta 1 as well.
1. Adding repositories
you can get access to it using:
a. synaptic package manger
System menu —> Administration —> Synaptic —> Settings —> Repositories
b. System menu —> Administration —> Software Sources
Common repositories already added on software sources by ubuntu and kubuntu. some application need to add extra repositories to be able to install it in your machine, will use this as example
deb http://ppa.launchpad.net/moovida-packagers/ppa/ubuntu karmic main
access the software sources, will ask you for root password then go to other software and press add button and paste the apt line like this one up there
If you want to backup all repositories you already have type this command on terminal
sudo cp -i /etc/apt/sources.list /etc/apt/sources.list_backup
This will copy you repositories list to this folder “./etc/apt/ ” with name called sources.list_backup
2. adding repositories key
some application need repositories key to get rid of so warning massages during the installations
so you will find more instructions on the website for installing this package and it will mention repositories key you can add it directly from the terminal.
That’s it for now.
Already reviewed ubuntu 10.04 alpha 3 here, as you will see in this post a big difference between ubuntu 10.04 alpha 3 and beta 1 version, New default theme that mentioned on ubuntu fresh look post ….
this is the hardware specification used to run this version of ubuntu 10.04
- 1 core processor 2.1 Ghz
- 1 GB of ram
- 12 Mb of video memory
with this hardware spec it was working great guys, so i believe if you have a decent machine it will work better.
Installation process :
Installed on Virtual machine “sun virtualbox”
First Boot after completing the installation
“Close, minimize, maximize” button in the left side of the title bar
More option added to right click menu for sharing to ubuntu one, moving to and copy to even it’s a file or folder
Pitivi default video editor
New look for Ubuntu software center
Yahoo is the default search engine for firefox 3.6, but it’s up to you can change it later to any other search engine
Terminal background color looks really good specially with this theme, also it’s up to you can change it later.
New menu to control your chat account what ever it’s ” pidgin or empathy” , controlling Gwibber, and ubuntu one
Gwibber works really good here , I faced many problem with using it on ubuntu 10.04 alpha 3 version. but it’s working great now even it’s a development version till now.
Sound preference with better control access menu.
Overall after the installation:
It was working really good, much better than the older version “alpha 3″
Ubuntu 10.04 beta 2 will release at 8th of April, and the final version will release 29th of April.
with first installation on virtualbox with 16 mb of video memory it was working a little bit slower.
Please guys leave your feedback, try to install it in your machine and report any bugs you faced so the development community able to fix many bugs for next release.
According to ubuntu 10.04 schedule, it was released yesterday, but Steve Langasek announced that it will be delayed one more day to Friday March 19 ,
Dear developers, Owing to some late image rebuilds for a couple of critical issues that we didn't want to leave our beta users subjected to, validation of 10.04 Beta 1 is still in progress. This means that Beta 1 will not be released on Thursday, March 18 as planned; it will be released tomorrow, March 19. To help us release the beta with confidence tomorrow, please consider participating in the ISO testing today, as described at <https://wiki.ubuntu.com/Testing/ISO>. Also, as you're going through ISO tests, please also help us fill in the blanks on <https://wiki.ubuntu.com/Testing/Plymouth> so we can complete our understanding of the remaining boot-time issues affecting Beta 1 and make Beta 2 truly spectacular! Thanks, -- Steve Langasek On behalf of the Ubuntu release team
Fixed a lot of bugs since alpha 3 version, improved nvidia graphics driver, ubuntu one syncing, new themes, we reviewed in ubuntu fresh look.
Will review it as soon I done download it.

Easiest way to install software on Ubuntu is using DEB Packages, cause Ubuntu distribution based on Debian distribution, unlike Fedora, Redhat, and CentOS using RPM packages. ” Will cover how to install/Uninstall RPM packages on Next Post”
so, will begin with
1. Installing DEB packages
Ubuntu make it really easy to install softwares on your distribution by using ” Ubuntu software center ” Or using ” Synaptic Package Manager ” , but sometimes you can’t find these packages you want listed on “software center or synaptic” but you already have a DEB packages and you want to install it using terminal.
For example I Downloaded application called ” Skype ”
http://download.skype.com/linux/skype-ubuntu-intrepid_18.104.22.168-1_amd64.deb ” DEB package name on Red color “
” Download location : Home/Your Username/Downloads “
That’s it for now, and will cover Installing/uninstalling RPM packages on next How To’s …?
