Founded: Jun 2014 Members: Roman Savochenko Description: OpenSCADA servers infrastructure representing, tracing and managing. Managing task: ![]() Funding: 89% from the request, mostly by the ![]() | ![]() |
The page aimed for server's infrastructure of OpenSCADA project represents, traces and manages.
From begins the OpenSCADA resources hosted on a main server of DIYA Ltd and the server's details and specific were not possible to publish. From 2015 year the OpenSCADA project had own a server and an internet channel thanks mostly to
Beams&Plasmas
funding. From 2016 year all resources of the project OpenSCADA were moved to the new server and domain name "oscada.org" was switched to it. For the domain name "oscada.org" and it's DNS uses
the Hosting Ukraine, the configuration shown in Table 1.

The OpenSCADA server located now into a quarter of author of the OpenSCADA system it is Roman Savochenko. For link to the global network (Internet) used a service of Internet provider Kyivstar in Kamjanske city of Ukraine. The provider uses the conception of Fiber To The Building (FTTB) and the internet channel's bandwidth now it is 30Mbit/s. For temporary access (for dynamic IP) used domain name "oscada.dlikddns.com" which allowed yet and next there was registered a static IP 134.249.149.50 to which now connected the main domain "oscada.org". Hardware configuration of the server shown into Table 2:
Table 2: Hardware configuration of the OpenSCADA server.

In base of the program environment used OS Linux distributive
Debian 7 (Wheezy). For external services isolation and some other purposes used the
OpenVZ lightweight isolation into different Virtual Private Servers (VPS). Into mostly VPS also used Linux distributive Debian 7 (Wheezy), sometime used Debian 8 (Jessie) and ALTLinux T6. Hardware server (HS) it is x86_64 program environment but the VPSs mostly used x86 environment especially for high demanded tasks, as the result we have the memory consumption 1.2GB instead 2GB of even-functional x86_64 pure environment. The program environment structure shown in Figure 1.
File system of the hardware server (HS) has not a swap partition and has two main mirrored partitions:
- "root (/)": 9.1GB
- "data (/data): 908GB
Besides only VPS containers management by OpenVZ the HS environment also has some services for the external and internal networks:
Address: ftp.oscada (192.168.0.10)
Service: exclusively provides a public file-service for OpenSCADA resources. To use the service go to ftp://ftp.oscada.org.
Base of the VPS: OS Linux distributive Debian 7 (Wheezy) x86, file server ProFTP.
The FTP has next partial tree with the descriptions:
Address: db.oscada (192.168.0.11)
Service: exclusively provides different DBMS for internal and by VPSes using.
Base of the VPS: OS Linux distributive Debian 7 (Wheezy) x86, allowed next DBMS: MySQL, PostgreSQL, FireBird, OpenLDAP (slapd).
Table 2.2: Allowed DBMS and its using.
DBMS | Using |
MySQL | TYPO3 (![]() ![]() |
PostgreSQL | Some OpenSCADA tests. |

OpenLDAP | Jabber users authentication. |
Address: svn.oscada (192.168.0.12)
Service: provides the control versions systems.
Base of the VPS: OS Linux distributive Debian 7 (Wheezy) x86, allowed next control versions systems: Subversion, CVS.
CVS it is old-deprecated control versions system used up to year 2005 by the OpenSCADA project and some projects of firm DIYA Ltd of it's author Roman Savochenko. For now CVS provides only for the compatibility and supports only guest access: $ cvs -d:pserver:guest@oscada.org:/CVS_R co OpenScada
Subversion it is current control version system using now by the OpenSCADA project. Supported two managing and two display connections:
Address: http.oscada (192.168.0.13)
Service: provides different HTTP-services which mostly based on Apache2 web-server.
Base of the VPS: OS Linux distributive Debian 7 (Wheezy) x86, Apache web-server.
Main configuration file of the virtual hosts placed into "/etc/apache2/sites-available/openscada.conf". EMail configured as simple relay (into file "/etc/postfix/main.cf") to the server's email server, into different VPS.

Service: provides instant messages server.
Base of the VPS: OS Linux distributive Debian 8 (Jessie) x86, Jabberd2. The VPS was successfully updated from the Debian 7 minimal VPS template but no that VPS of x86 platform allowing for Debian 8.
For users authentication of the instant messages server used LDAP on the VPS "DB". For contacts store used the table "jabberd2" on the DBMS MySQL on the VPS "DB". The configuration and the table "jabberd2" were taken on the old server and successful adapted on the new.
Address: bldrALT32.oscada (192.168.0.100)

For the Live-disks unmistakable building the original packages repositories of ALTLinux 5 and 6 located in the server and it is regular mirroring performed. By the OpenSCADA project in different times was created a self repository of packages included builds of the OpenSCADA packages and other programs with fixings and renewals, for details see to the Automation Linux distributive of the project OpenSCADA. Next actual repositories for ALTLinux allowed on the OpenSCADA server:

For the Live-disks unmistakable building the original packages repositories of Debian 7 and 8 cached on the server by "APT cacher of new generation" and some repositories like Trinity DE are located on the server and it is regular mirroring performed by "APT mirror". By the OpenSCADA project was created a self repository of packages included builds of the OpenSCADA packages and other programs with fixings and renewals, for details see to the Automation Linux distributive of the project OpenSCADA. Next actual repositories for Debian cached and placed on the OpenSCADA server:
