Porting OpenVPN to Windows CE Platform
Ešner, Oldřich ; Ráb, Jaroslav (referee) ; Ryšavý, Ondřej (advisor)
The motivation for inception of this MSc. thesis which follows on from a term project of the same name was the transfer of the application for building private virtual OpenVPN networks from Windows XP operating system to Windows CE Embedded 6.0 platform. The project deals with virtual private networks in general and looks more closely at its implementation - OpenVPN. It also introduces the basic features of the Windows CE operating system. The project goes on to describe device drivers in NT-based Windows operating systems, the Windows Driver Model used, the NDIS network interface model and also the model of Windows CE drivers - the Stream Interface Model. The project continues with a~description of communication in OpenVPN application and primarily the role of TUN/TAP virtual network interfaces. This is followed by a proposal for transfer of TUN/TAP adapter drivers together with a description of limitations and necessary modifications between both platforms. As a result a TAP network device driver is implemented whose function is verified by test application that emulates the behaviour of a TUN adapter. The project concludes with an evaluation of the achieved results, the possibilities for further work on this theme and with the overall contribution of this project.

Test Planning Tool Extension for Distributed Systems
Mészáros, Filip ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This bachelor thesis is about automatical software testing using the testing scheduler. It describes creation of the extension for the existing testing scheduler, so it will be possible to split effectively a group of tests to segments, that will be executed independently on each other. Tests are splitted according to the common characteristics of the enviroment, that need to be prepared for each test, and according to the dependencies between the tests. Furthermore, it describes what optimizations are used for splitting of the tests to subsets. Each subset of the tests runs on a standalone testing system, so the time needed for succesful completion of testing with the given set of tests is reduced. Created tool is succesfully used during everyday testing of the several products in the Acision company, to which was this tool made.

Framework Flex for Information System Implementation
Čech, Pavel ; Ščuglík, František (referee) ; Ráb, Jaroslav (advisor)
The purpose of this thesis is to analyse the development surrounding Flex, a program produced by the company Adobe and its use in information system creation. With this purpose in mind, a demonstration application which uses basic elements of the examined area, and clearly demonstrates their use, was suggested and produced. In the application, an emphasis is on the processing of data acquired from MySQL database with the help of language PHP, which transforms the data into XML format.

Instant Messenging System
Gach, Marek ; Kašpárek, Tomáš (referee) ; Ráb, Jaroslav (advisor)
Present world of server applications is dynamically developing branch of IT. With multicore CPU appearance well designed multithreading applications gain additional performance. This thesis is trying to sketch out some basis of multithreaded application creation and synchronisation. Usage of this principles will help me to develop general-purpose parallel server core. Whole semantics of communication protocol for message sending is based on that core.

Mobile Switching Centre Emulator
Králíček, Jan ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This thesis attempts to provide basic overview of the topic of the GSM system and tries to design Mobile Switching Centre Emulator that could perform the operation Location Update. The first part of this thesis describes the principles and specifics of the GSM network (network structure, the operations required to support user mobility, network entities, etc.). The second part of this thesis describes the SS7 signaling protocols, SIGTRAN and MAP protocol. The final part deals with design of the emulator.

Processor of TSQL2 on Post-Relational Databases in Oracle Database
Szkandera, Jan ; Ráb, Jaroslav (referee) ; Rychlý, Marek (advisor)
This thesis focuses on temporal databases and their multimedia and spatial extensions. The introduction of this work summarizes results in the area of research of temporal databases - key concepts of a TSQL2 language and post-relational extension of Oracle database are introduced. Main part of the thesis is design of an interpreter as a layer between user application and relational database. In the next part of the thesis control of integrity constraints in temporal databases are discussed. Result of this work is functional interpreter of TSQL2 language able to store post-relational data.

Open-Source Software Tools for Network Diagnostics
Loffay, Pavol ; Ráb, Jaroslav (referee) ; Matoušek, Petr (advisor)
The aim of this work is to make a research of existing open source tools, which are concerned with the diagnosis of the network transmission in the form of measuring of throughput and other basic parameters. The work is devoted to the construction of methodics for testing and comparing devices between themselves. The result of the work is recommendation to an ordinary customer the right application for measuring of given network transmission parameter.

NNTP Server as a Windows Network Service
Loupanec, Josef ; Ráb, Jaroslav (referee) ; Očenášek, Pavel (advisor)
This work includes specification and analysis of requirements, design and implementation of the internet news server. The server controls newsgroups and associated news. It provides availability of the articles by NNTP protocol and HTTP protocol (by web interface). The server supports a user authentication and an optional proxy mode, when all NNTP requests are resent to another remote NNTP server. A mechanism that provides news-downloading from remote NNTP servers and performs distribution function is included too. The application is designed to run on MS Windows NT (and higher version) as a NT service. The server is configurable by a graphic user interface. The work also includes theoretical information needed for successful accomplishment of the above-mentioned requirements.

Monitoring of User Activities on Workstations
Skopal, Aleš ; Ráb, Jaroslav (referee) ; Matoušek, Petr (advisor)
This master's thesis deals with proposal of a system for monitoring of user activities on workstations Windows XP over .NET 2.0 platform. The system should monitor running programs, processes and find out user activities in these programs like movement of the mouse or writing on the keyboard. A part of whole project is a suggestion of the system which contains specifications of requirements for this system, creation of the architecture, creation of important models, suggestion of the communication between separated part of system and final compile of results. The project should get information about user's activities and also information about usage of software installed on these workstations. The final system will be tested by use case study. Last but not least, project deals with ethic questions in the context of monitoring of users and discuss law questions about this project.
