About Exton|Defender SRS (in three versions)




Exton|Defender SRS is a Linux system available as a bootable USB stick (based on Slackware 14.1, 64bit - version 140607) and Live DVD (based on Mageia 4, 32bit - version 140403 and Fedora 20, 64bit - version 140407) for administrating or repairing your system and data after a crash. Exton|Defender aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the hard disk partitions. It comes with a lot of Linux software such as system tools and basic tools (editors, Midnight Commander, network tools). Exton|Defender can, however, also be used as a normal Linux Desktop System. It requires no hard drive installation, but can easily be installed to hard drive if you want. Desktop environments: LXDE in version 140403, Mate 1.8.1 in version 140607 and Cinnamon 2.0.14 in version 140407.


System Tools included

NTFS-3g, GParted 0.16.0, PartImage 0.6.9, Shred 8.19, Sfdisk (util-linux-ng 2.21.2), Rsync 3.0.9, Ddrescue 1.16, FSArchiver 0.6.12, TestDisk 6.13 and Midnight Commander 4.8.4. Other programs (among many others): LibreOffice, NetworkManager, Firefox, Thunderbird, Gimp, Samba, Java (JDK 7u9) and Java Runtime Environment (JRE), Emacs, Safecopy 1.7, kernel headers (Mageia 4 and Fedora 20) and many compilation tools. See a complete LIST of all installed packages 140403 (Mageia version), 140607 (Slackware version) and 140407 (Fedora version).




About Slackware
Slackware is the first widely-used Linux system, which is still developing. Slackware has existed since 1993. In comparison with for example Ubuntu and Linux Mint, many people believe that Slackware is "difficult". Any novice can quickly learn to use Ubuntu they say. My remaster Exton|Defender 14.1 is however just as easy to use as Ubuntu and/or Linux Mint. Some tend to complain that the Program Management in Slackware is awkward. That was perhaps earlier the case, but not anymore. Now we have the Application Managers Slackpkg, Sbopkg and GSlapt - a GTK version of slapt-get. They are a piece of cake to use! All three Program Managers are preinstalled in Exton|Defender SRS. Users of Synaptic will feel at ease with GSlapt.

NEWS 140607 re. Exton|Defender based on Slackware 14.1

I’ve made a new version of Exton|Defender 64 bit based on Slackware 14.1. It uses Mate 1.8.1 and kernel 3.14.5-x8_64-exton. Mate Desktop environment is not included in Slackware's official repositories. To be able to install Mate in Exton|Defender I had to add Salix's repositories. The MATE Desktop Environment is the continuation of GNOME 2. It provides an intuitive and attractive desktop environment using traditional metaphors for Linux and other Unix-like operating systems. Note: I've also arranged it so that version 140607 can run from RAM. I wonderful way to run a Linux system. I.e. super fast! When Exton|Defender has booted up from the USB stick you can eject the stick.

NEWS 140407 re. Exton|Defender fc20 (Fedora 20)

I’ve made a new version of Exton|Defender 64 bit based on Fedora 20. It uses Cinnamon 2.0.14 and kernel 3.13.8.

NEWS 140403 re. Exton|Defender mga

I’ve made a new version of Exton|Defender based on Mageia 4 32bit. It uses LXDE and kernel 3.12.13.

About Exton|Defender - Mageia 4 version

About Fedora

Please read this overview.

Special features in version 140607 of Exton|Defender
I have replaced Slackware´s 14.1 original kernel huge with kernel 3.14.5-x86_64-exton with support for "everything". Kernel 3.14.5 is the lastest available stable kernel for downloading from All component software is upgraded to the latest version by now (20140607).

Note that Exton|Defender (Slackware version) shall/must be installed on a USB pen drive of at least 2 GB.Note also that, among other things, Exton|Defender 2014 can be seen as an alternative to Mandriva Flash (which costs 50 Euro). 

The password for root (superuser) and live (normal user) is: root/live in the Mageia 4 version of 140403 and in the Slackware version of 140607.
In version 140407 (Fedora 20) there is no password for liveuser and root. Just login to Cinnamon as liveuser and/or root without any password. Note: When Exton|Defender mga has booted up you will end up at Slim‘s login manager. First press F1. It will look like this. (I.e. choose session LXDE). Then log in to LXDE as user live or as root. Passwords: live/root.

Configuring X
X is auto-configured during the boot from the USB stick/DVD.

Default language
The default language (locale) is set to English.

Ubuntu/Kubuntu/Mint and many other so-called beginner distributions (and other Linux systems) use sudo to do something that requires root (superuser) privileges. There really is no need for a root password. "Examples of Command": sudo mkdir /usr/MyFiles. In version 140607 (Slackware) you can also directly become root with sudo su. Read HERE about how sudo works. I have installed the Sudo program in Exton|Defender 14.1. This means, among other things, that Linux users used to Ubuntu also can identify with Exton|Defender Slackware version). When logged in as liveuser in the Fedora version from 140407 just run the command su to become root. (You can also run sudo su).

The ZIP file (for "installing" to a USB stick) is of 1120 MB - Slackware version.
The ISO-files is of 904 MB - Mageia version and 1360 MB - Fedora version.

Installation of missing programs with Slackpkg, Sbopkg or GSlapt in version 140410 - Slackware
I have installed Slackpkg and Sbopkg. With Slackpkg/Sbopkg all software can easily be installed or uninstalled. The entire system can also be upgraded with Slackpkg. Command: slackpkg upgrade-all. Read more about how to use Slackpkg HERE. It is very easy/intuitive. Thus, installing a new program with the command slackpkg install MyNewProgram. With Sbopkg you can manage so-called Third-party programs. Read HERE about how to use Sbopkg. You can also run the command sbopkg -help as root to list all possible commands. The corresponding command is re. Slackpkg is slackpkg help. You can also use the Application Manager GSlapt
a GTK version of slapt-get. GSlapt works in the same way as Debian/Ubuntu's Synaptic. You can easily upgrade your entire system with GSlapt.

Installation of Exton|Defender (version 140607) on a USB pen drive of at least 2 GB
The installation is easiest to do in Windows XP/Vista/7/8. Follow these steps:
1. Format the USB stick with the file system FAT/FAT32. (Right click and select Format)
2. Unpack the downloaded ZIP file (with WinZip, WinRAR, 7-Zip or...). You will see that there is one folder called defender.
3. Copy the aforementioned folder defender to the USB stick.
Open up a command prompt as administrator (very important!) and make sure you are in G: (or the name your USB stick got on your computer).
5. Run the command cd defender/boot followed by bootinst.bat. This is because the USB stick must be made bootable. Important: Do not run the command when you are in the C:. (If you do then, Windows 8 - or whatever you have in your C drive - can not be started). If you get error messages when running the command bootinst.bat, you should not worry about them. Just click a few times on "Retry". If you still get an error message saying that the operation has failed, do not worry about that either. The USB stick is bootable if you followed the steps in paragraph 1-5 above.
6. Set the BIOS so your computer primarily will boot from USB HDD (or similar).
7. Restart the computer with the USB stick in place. (See also additional info on this page below).
NOTE1: All system changes are persistent. NOTE2: To be absolutely sure that persistence will work you really should do the installation in a Linux system and format the USB stick with ext4. Example: run cd /mnt/sdb1/defender/boot followed by ./

NOTE ALSO: It appears that not all USB sticks are suitable for topical purposes. I. e. they can not be made bootable. I myself have experience of brands Kingston DataTraveler, SanDisk Cruzer Micro and Sony Micro Vault. The first two works (for me). You may not use USB sticks of older model. They may work, but mostly bad. If you - after the installation of Exton|Defender to the USB stick -  get different error messages when you try to run the system from the stick it is because the stick is not "good" enough.

Installation to hard disk - Mageia 4 version
Exton|Defender mga/Mageia can easily be installed to hard disk. Just follow the instructions. NOTE: If you want your own user/users you'll have to add him/them when you have started up Exton|Defender mga from hard disk. Do it as root with the commands useradd MyUser and passwd MyUser or go to Mageia Control Center >> System >> Manage users on system. It will look like this.

INSTALL Exton|Defender (version 140407) on a USB stick of at least 2 GB
Use Fedora LiveUSB-Creator in Windows. Works very good. All system changes are PERSISTENT.

INSTALL Exton|Defender (version 140607) to hard drive

Use this INSTRUCTION. You can (if you want) use Grub2 as boot loader.

INSTALL Exton|Defender - FC20 (version 140407) to hard drive
Just use Anaconda (Fedora's installer). Please read this INSTRUCTION. You can (if you want) use Grub2 as boot loader.

Slackware 14.1 and/or Mageia 4 and Fedora 20 is at least as "good" as Ubuntu 14.04/Linux Mint 17 and/or OpenSUSE 13.1. I think. Tell me what you think of Exton|Defender SRS in combination with LXDE, Mate 1.8.1, and/or Cinnamon 2.0.14. Did you find the included Rescue System Tools useful? I am also interested in hearing about how the save features in Exton|Defender (version 140607) works for you. They should normally cause no problem, but...
