Monitoring system for applications and system of linux servers
Janovský, Martin ; Chmelař, Milan (referee) ; Janovič, Filip (advisor)
Bachelor's thesis solve the problem sight above distant Linux's servers. She describes technology, that are used for following servers. Further is described application by herself. Main problem at distant sight is, that the oneself have to check every one server separately. This performs central server provided by web server with the support language PHP and database MySQL. Central server creates interface between user and servers. All application is built on PHP, MySQL and SOAP messages. Server, which is monitored, is equipped web server and application for automatic execute process. All application is then built on exchange SOAP messages, which contain monitoring information. These data are preserved in database and further used for various statistics and graphs. By the help of web interface on central server can be information suitable displayed. This interface makes it possible to do action above single processes. Restarted or stopping process is at distant management used frequently. Naturally is respect emphasis on safeness. Optimal place for placement these application is operator centre or administrator's computer. Demand user has then displayed all monitored servers on monitor. On nonstandard state of process user is promptly alert. This situation he can promptly solve.

Scale free topology networks focused on MANET technology
Sehnálek, Adam ; Janovič, Filip (referee) ; Skořepa, Michal (advisor)
The main goal of my bachelor thesis is familiarization with a question of computer network with free topology aimed at MANET technology, or more precisely Motorola MESH. It deals with simulation of influence of bundle number within the network on data transfer using all possible routing protocols in Opnet Modeler. The first part contains description of basic networks with free topology and their characteristics. It devotes mainly to Mesh networks and mostly to Motorola technologies that are described there. All three Motorola network types can be found there - MOTOMESH Solo, MOTOMESH Duo and MOTOMESH Quattro. The second part of the thesis focuses on routing protocols available for MANET networks in Opnet Modeler. Principles and basic characteristics of protocols AODV (Ad-hoc On-demand Distance Vector), DSR (Dynamic Source Routing), OLSR (Optimized Link State Routing protocol) and TORA/IMEP (Temporally-Ordered Routing Algorithm) a GRP (Geographic Routing Protocol) are described there. The closing part of the thesis is dedicated to the simulation of individual protocols and their influence on transferring multimedia data through the network. It includes exact process of making the MANET network, configuration of individual components, choosing the necessary characteristics and after simulation view. It concludes also the final summary of all simulated protocols.

Application for displaying cartographic data in web environment
Duchovič, Adam ; Janovič, Filip (referee) ; Koutný, Martin (advisor)
This thesis deals with designing application for displaying cartographic data and its implementation to the web environment. The goal was to design an application which will be independent on platform. Introduction provides basic information about the Java programming language, next chapter introduces to the applied developing environment. Then the thesis deals with an option of dividing the solution on two possibilities and the concept of displaying cartographic data. Further is described design procedure of programming application with its implementation to the web environment. Modularity of this application was ensured during its realization. In the conclusion the process of developing application is resumed and both of the solutions are compared.

System for Bibliography Database Management on the Internet
Daněk, Jiří ; Janovič, Filip (referee) ; Rajmic, Pavel (advisor)
The aim of this master´s thesis was to create a web interface for working with bibliographic quotations. This whole project was created to easy writing bibliographic quotations in author´s piece. The system allows inserting, searching and managing bibliographic quotations. These quotations can also be exported into four types of files : RTF, XML, HTML, a database bib file. The czech norms CSN ISO 690-1 and also CSN ISO 690-2 are fully supported. Whole the system is based on language like PHP which is used for developing dynamic web pages. The system contains graphical user interface, which is simple to use. The web interface is fully functional and it is ready for using by autors of scientific publications or students in schools.

Network attacks of Linux operating system
Valčák, Richard ; Janovič, Filip (referee) ; Pelka, Tomáš (advisor)
Main objective of this bachelor thesis is to inform with the most famous security attacks, describe their characteristics, evaluate risk degree and suggest security against of these attacks. The bachelor work presents theoretical and practical part focused on security attacks of Linux operational system. First chapters describe operational system security shell theory. Followed by the most frequent attacks like Buffer overflow, ARP Cache poisoning, SYN flood , Denial of Service, DHCP, which are described theoretically, demonstrated by these examples and possible security assignment against this attacks registered. Basic theoretical system Linux knowledge is necessary for the practical part of the bachelor thesis.

Management of apache aplication with web GUI
Hošek, Roman ; Malý, Jan (referee) ; Janovič, Filip (advisor)
This bachelor’s thesis deals with a design and implementation of a web application aimed at Apache server configuration. It analyses the question of configuration and its possible solutions. The PHP scripting language with the data storage in MySQL database was chosen for the final application. Linux distribution Debian serves as the host system. The thesis contains descriptions of applied components features and it is particularly focused on the question of virtual hosts. It also includes an installation and application manipulation guide . The vadmin system maintains an easy creation of virtual hosts adjustment just by the help of a web browser.
