1. VEOS 8.7 Sakhalin (SHA-256 checksum) for minimal installation.

Archived versions

The most popular current method of installing an operating system on a computer is to install it from an installable USB memory stick.

To create a USB installation disk on Linux/Unix, run the dd command:

> dd if=VEOS-8.7-x86_64-Minimal.iso of=/dev/sdz bs=1M

To burn an ISO to a USB drive on Windows, you can use the Rufus program, must select the “Write to DD image” writing mode:

• Rufus main screen

• recording mode selection dialog box

The command parameters are similar to those on Linux. The DD distribution for Windows can be downloaded here.

When using dd for Windows, first run dd –list and, after carefully reviewing the NT block device list, select a device similar to {\?\Device\Harddisk1\Partition0 with a description like “Removable media other than floppy. Block size = 512”. Be careful with the choice of device, otherwise you may corrupt data on other disks!

The most common way to install an operating system on a computer is to install from an installation DVD.

An ISO disk image file is a special format file prepared to burn on a disk. To burn an ISO image in the MS Windows use special programs: SCDWriter, Nero BurningROM and others.

The entire process of burning an installation disk with Small CD-Writer consists of the following steps:

1. download the image of the distribution disk;
2. download the Small CD-Writer program archive http://gluek.info/wiki/_media/software/scdwriter14.zip;
3. extract program files from the archive to any directory;
4. insert a blank disc into the drive;
5. enter the directory and run SCDWriter.exe;
6. start Disk → Burn ISO image to disk and, in the window that appears, specify the path to the disk image;
7. click the Burn button.

To burn ISO images it is recommended to use K3b or Brasero programs that come with any Linux distribution.

The entire process of burning an installation disk with K3b consists of the following steps:

1. if the k3b program is missing, you need to install it on your system using the standard software installation tools for the distribution you have;
2. run the k3b program. If properly configured, the program will tell you that there are no problems with the system and will prompt you to proceed to disk burning;
3. in the Service main window menu, select Burn DVD image;
4. in the Burn DVD image window that appears, click the Choose file to burn button. A dialog box will open in which you need to select the ISO image to burn and then click the OK button;
5. the k3b program will show you the information about the ISO file and start calculating the checksum. This operation may take a few minutes. The checksum you get may be compared with the MD5SUM on the distribution page;
6. if the checksums do not match, that means you have selected a wrong file for burning or the downloaded ISO image was broken during data transfer over the network;
7. if the checksums match, insert the disk into your drive. Wait for the Start button to activate;
8. click the Start button.

To boot your computer to install the system, you need to use the media containing the VEOS distribution.

After successful initialization of the hardware, the bootloader menu with installation options is displayed:

Selecting the normal installation option launches the graphical interface of the installer program. The installation process is divided into steps. Each step is dedicated to configuring or installing a particular feature of the system. The steps follow one after the other. You can move to the next step by pressing Next. If necessary, you can use the Back button to go back to a previous step and change the settings.

Technical information about the installation progress (log file) can be viewed by pressing Ctrl+Alt+F1, return to the graphical installer – Ctrl+Alt+F7. By pressing Ctrl+Alt+F2 the debugging virtual console opens. Each step is accompanied by brief help that can be accessed by clicking the Help button or by pressing the F1 key. The following steps are used to install the system:

1. choosing the language of the installation interface;
2. configuring OS installation options – keyboard layout, language support, date and time zone settings, disk partition preparation, network configuration, security policy configuration, and administrator account creation;
3. installing the system on the selected disk;
4. finishing installation and rebooting.

If you received a preinstalled system from us, please immediately refer to the Appliance installation instruction section.
Otherwise, you need to install the VEOS operating system on your server yourself and give us remote SSH access and root rights to perform the installation and initial configuration of the platform. After the work is completed, the remote access can be closed.

1. Create a vasexpertsmnt user:

    adduser -m -G wheel -u 3333 vasexpertsmnt 

2. Set a complex password for the user vasexpertsmnt:

   passwd vasexpertsmnt

   For convenience, you can generate a password using openssl:

    openssl rand -base64 15 

3. Save the password for vasexpertsmnt.
4. Set permission for users of the wheel group to use all commands on behalf of all users, for this you need to add to /etc/sudoers the line:

   % wheel ALL=(ALL) NOPASSWD: ALL

5. To provide remote access via SSH and set restrictions on valid IP addresses from the list:

!Save your settings as the server will be rebooted during installation!

After making sure that remote access via SSH is provided, send to technical support of VAS Experts (Service Desk) file an application for installation of the Stingray SG DPI license with the password and username for SSH access.
