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:
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, Octave 3.6,4, OpenCV 184.108.40.206, jQuery UI 1.10.3, and LINQ 220.127.116.11.
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.
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
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
To choose other language, please do the following steps.
for example, to install 'ja'
sudo apt-get install language-pack-ja language-pack-kde-ja language-pack-gnome-ja
When you encounter NVidia driver error (for example X Server crash), I recommend you to re-install NVidia driver.
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade sudo apt-get --reinstall nvidia-current nvidia-current-dev
You can install to a hard disk.
In detail, there are two other methods by which to run a USB key.
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.
The following software list is tentative. Some softwares are missing in the following list. Some softwares in the list are not installed to save disk space in some of the DBLab distributions.
