DBLab is remixed system derived from the Linux operating system
I present the DBLab distributions as remixed system derived from Linux operating system (OS).
This remixed system features system settings, various up-to-date software packages, and miscellaneous useful software (They are listed below in this Web page).
Note that Linux OS is widely used.
As such, Linux OS is suitable as the base of a distribution.
The remixed system derived from Linux OS is set up as follows:
Install Linux OS.
Update Linux OS.
Set up private repositories to install additional software packages.
Install additional software packages.
Install other freeware that is not packaged.
Remove unredistributable software from the remixed system. The original Linux OS may include unredistributable software.
Adjust the system settings, such as Internet connection, language, and keyboard.
Adjust the desktop settings, such as the login screen, desktop layout, and desktop window manager settings
Here, the goal of the DBLab distributions is to provide an all-in-one desktop system based on the Linux OS with database software and other related software tools and programming libraries.
The DBLab distributions contain
database management system software (SQLite3, MongoDB server and client, Redis server and client, MySQL client library),
a database software tool (SQLiteman),
text editors (leafpad and emacs),
a binary editor (ghex2),
software development tools,
libraries for programs, system administration tools,
forensic and security tools, graphics/photography/image/sound/video tools, internet tools, office tools, science tools, CD/DVD/ISO tools, emulators, and accessories.
The total disk usage of the system is approximately 21 GB when a distribution is installed
in a hard disk drive,
and the number of total software packages installed in Step 4 above is approximately 3,000. The freeware installed in Step 5 above consists primarily of the latest versions of programming languages and development environment software, including Eclipse 4.3.2, Octave 3.8.1, MatlabFns, Rstudio, redis-2.8.9, mongodb, umongo-1.6.1, cloudcompare-2.5.3, OpenCV 2.4.9, OpenNI, gmic-188.8.131.52, ffmpeg-2.2.2, juman-7.0, dlib-18.7, XML-XML2JSON 0.06, jQuery UI 1.10.4, LINQ 184.108.40.206, Plot Digitizer.
List of DBLab distributions
The current version of the DBLab distributions is based on the following desktop Linux OS. They are variation of the Ubuntu OS.
The system settings (Step 7 above) include the following items.
The default settings for the system language and keyboard assume a particular country (i.e. US).
Please change system setting by yourself. The current settings are described below.
The name of the default user: ubuntuuser
The password of the default user: uest1204!, uest1310! or uest1404!. (see the download page).
Internet connection: DHCP
Firewall setting: deny all incoming packets except port 22/tcp and 80/tcp.
In order to deny all incoming packets, I executed "sudo ufw default DENY incoming" command, and then I executed the following commands to allow 22/tcp and 80/tcp.
sudo ufw allow 22/tcp
sudo ufw allow 80/tcp
servers softwares, openssh-server, gnome-user-share and vino are un-installed.
To install openssh server, execute the following
sudo apt-get install openssh-server
To install vino server, execute the following
sudo apt-get install vino
To install apache2 Web server, execute the following
sudo apt-get install apache2
System language setting: US
To choose other language, please do the following steps.
insert the live the USB Key into your PC, restart your PC,
and configure BIOS to boot from the USB key.
boot from the USB Key.
In detail, there are two other methods by which to run a USB key.
(method 1) Run the USB key as a virtual machine on another host OS.
(method 2) Boot from a USB key after configuring the BIOS to allow booting from the USB key (described above).
(method 3) Install a USB key to a hard disk, and boot from the hard disk.
There is difference between the above three methods.
The first method 1 is slowest, but the virtual machine is isolated from the host OS, and you may feel safe when using a virtual machine.
The second method 2 is faster than method 1,
but you may have difficulty in configuring the BIOS.
The third method 3 is the fastest and can handle large data files.
However, the installation task in method 3 is tedious.
Note that methods 1 and 2 can handle persistent data. Since USB keys are inexpensive, storing a gigabyte-sized database is not a problem.
