Monitoring of communication properties in Internet
Iľko, Pavol ; Červenka, Vladimír (referee) ; Komosný, Dan (advisor)
This thesis deals with measuring transmission parameters of the Internet network, in particular latency of ping, SSH protocol and bandwidth. The thesis is divided into a theoretical and a practical part. Theoretical part describes PlanetLab network, its brief history and contemporary projects. At the same time, tools for data mining from web pages are described. These information obtained from the theoretical part are used for creating PlanetLab nodes list and for programming applications which measure the network transmission parameters. Applications, list of nodes and obtained data are attached on DVD disc.

Universal Metering Device for LTE Mobile Networks
de Groot, Štefan ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
Predmetom diplomovej práce je skúmanie možností realizácie univerzálneho meracieho zariadenia v sieti LTE. Sú popísané základy M2M komunikácie a trendy v IoT. Cieľom práce je nájsť optimálny hardvérový základ, na ktorom následne bude možné konfigurovať LTE modem a získať údaje o stave a kvalite pripojenia k sieti. Následne bude vykonaná séria testov za účelom zmerania parametrov siete a výsledky budú spracované k prezentácii na webovom serveri vo forme grafov.

Automatic Tool-Chain Testing System
Aschenbrenner, Vojtěch ; Šuška, Boris (referee) ; Hruška, Tomáš (advisor)
Project Lissom is developing environment for design application specific processors or SoC (System on Chip). Project developes tools like assembler, disassembler, simulator, C compiler etc. Environment testing is required and It's main reason for this work. The work is about software testing, types of testing and about existing testing systems. The inspiration from existing systems is used for design and implementation Lissom testing system. System is comparing tools outputs with reference files. The system needs Bugzilla client end e-mail sender for complete functionality. These tools were also created.

A Tool for Shell-Script Analysis
Holomek, Jiří ; Janoušek, Vladimír (referee) ; Smrčka, Aleš (advisor)
This bachelor's thesis deals with analysis of scripts. In the current distributions of Linux or other operating systems based on the Unix principals, there is made a lot of configuration by using scripts. The main objective of this work is to create a program that analyses the scripts and also reports theirs functionality and safety to a user. According to my research the work is aimed to Bash language.

Filtering of Texts Extracted from PDF, OCR or Web
Žigárdi, Tomáš ; Plchot, Oldřich (referee) ; Szőke, Igor (advisor)
This bachelor thesis describes normalization of texts created by conversion of other formats and creation of pronunciation dictionaries. They are important in speech processing process. Mistakes caused by conversion and original solution of this problem are analyzed. Design and implementation of normalization steps and pronunciation dictionaries is shown. Results are compared with results of original solution of this problem.

System for Virtual Server Administration
Karban, David ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
There is coming trend of virtualization on modern computers. One computer may act like host for several guest virtualized computers. This has many advantages, like for kernel development, software testing, virus behaviour testing, saving HW resources. On the other hand, complexity of computer maintenance is growing too. This bachelor thesis describes a system, that can be used for management of many virtual servers and lower the manageability overhead. This work will create a generic control interface for virtualized computers. Interface will be adaptable and extendible. The development of this system is described from specification through analysis to concept and implementation of application.

A Framework for Static Analysis of Shell Scripts
Svoboda, František ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
The aim of this work is to create framework for static analysis of Unix shell scripts. Bourne-again shell is chosen as the primary subject of interest. The first part of the project discusses a principles of static analysis and current static analysis tools. The diploma thesis presents a framework based on modular system, which enables plug-ins to perform different kinds of analysis on scripts. Framework includes plug-in management, means of interaction, handling outputs and input setting. This thesis also contains the description of a few plug-ins, designed to perform basic analysis of scripts.

Automatic configuration of workstations in Cisco academy laboratory
Homolka, Jiří ; Jelínek, Mojmír (referee) ; Komosný, Dan (advisor)
My thesis is focused on the subject of working with distant stations connected with the laboratory control of Cisco academy. Station operations, i.e. laboratory control, have been carried in the environment of the Linux operating systems. The first part of the thesis includes a description of the laboratory, its network architecture and software equipment. Also, the VMware tool is described here. VMware tool is intended for virtualization of computer stations, where the virtual station is created. In this virtual station another operating system may be run. The problems of the command interpreter, its function and possibilities are described here too. Main attention is devoted to the Bash command interpreter and to the creation of the scripts. There are descriptions of the basic tools intended for the network communication with the distant stations. Among the most important parts belong the protected communication, the production of the autentization keys as well as the tool for data recording on more stations at the same time. The description of the access rights to the files and directories is included too. The target of this thesis was to create the scripts in the Bash programming language. The scripts are focused on working with the laboratory stations. They are the sublayers of the common project for this laboratory control. They were developed for the cooperation with the the web interface and MySQL database, created by Bc. Zdeněk Hrabal. The Scripts are intended for the finding information about the stations and virtual systems, and also for the recording images and configuration files of the virtual systems at the distant stations. Recording files and directories is enabled too. The other scripts deal with the erasing and changing of the rights of the particular files and directories. Setting commads with the super-user competence is used at this place. The scripts for the switching on and off the laboratory workstations were created too. To solve the problem described above I chose to develope more scripts. Each of them subserves the particular part of the task. The form of the input and output data of the scripts was select with the reference to the cooperation with the web interface and database. The data are implemented by the form of the input and output files. The output information and the process of the carried operations are displayed through the web interface. The scripts together with the web interface are placed and run from the school server adela.utko.feec.vutbr.cz. In the thesis the settings of the access privileges for the current directories and the files of virtual systems and scripts are presented too.
