About Exton|Defender SRS




Exton|Defender SRS is a Linux system available as a Live DVD (based on Fedora 26, 64bit - version 170909) 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 environment: Cinnamon 3.4.6.


System Tools included

NTFS-3g, GParted, PartImage, Shred, Sfdisk (util-linux-ng), Rsync, Ddrescue, FSArchiver, TestDisk and Midnight Commander. Other programs (among many others): LibreOffice (in fc26), NetworkManager, Firefox, Thunderbird, Gimp, Samba, Java (JDK 1.8.0) and Java Runtime Environment (JRE), Emacs, Safecopy, kernel headers and many compilation tools. See a complete LIST of all installed packages 170909. (Fedora version 170909).



NEWS 170909 re. Exton|Defender fc26 (Fedora 26)

I’ve made a new version of Exton|Defender 64 bit. Now based on Fedora 26, released 161122. It uses Cinnamon 3.4.6 and kernel 4.12.9.

About Fedora
Please read this overview.


In version 170909 (Fedora 26) there is no password for liveuser and root. Just login to Cinnamon as liveuser and/or root without any password.  (You will be automatically logged in to Cinnamon as liveuser).

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. Read HERE about how Sudo works. When logged in as liveuser in the Fedora version from 170909 just run the command su to become root. (You can also use sudo su).

Install Google Chrome (for Netflix)
You can't  run Netflix in Firefox. For that you'll need Google Chrome. Read this INSTRUCTION. You can install Google Chrome even while running Exton|Defender live.

The ISO-file is of 1730 MB - the Fedora 26 version.

INSTALL Exton|Defender - FC26 (version 170909) on a USB stick of at least 4 GB
Use LinuxLive USB Creator (LiLi) in Windows. Works very good. All system changes are PERSISTENT. Be sure to choose "Recognized Linux: Fedora 26 Workstation (Gnome) 64-bit". Watch this screenshot. You can also use Etcher. No persistence though. Watch this screenshot.

Installation to a USB stick in Linux
Use the following commands as root.
1. isohybrid exton-defender-fc26-64bit-cinnamon-1730mb-170909.iso
2. cp exton-defender-fc26-64bit-cinnamon-1730mb-170909.iso /dev/sdX (X can be /dev/sdb, /dev/sdc or....Check it carefully first so you don't lose data)
3. sync

INSTALL Exton|Defender - FC26 (version 170909) to hard drive

Just use Anaconda (Fedora's installer). Please read this INSTRUCTION. You can (if you want) use Grub2 as boot loader. Watch this screenshot when Anaconda has started.

Fedora 26 is at least as "good" as Ubuntu 17.04/Linux Mint 18.2 and/or OpenSUSE 42.2. I think. Tell me what you think of Exton|Defender SRS in combination with the Cinnamon Desktop. Did you find the included Rescue System Tools useful?
