Kernel module definition and networking server configuration for Linux operating system
Pecho, Ladislav ; Matocha, Tomáš (referee) ; Komosný, Dan (advisor)
The goal of my work is to create two computer labs lessons. The first one is a guide in writing a simple Linux kernel module, and in making a file inside the procfs filesystem. The content of the file can be decided as late as at the moment of reading. The second lesson describes the configuration of a server which allows a computer to boot over network. DHCP server is used with a TFTP server for file transfers which are both handled by the dnsmasq program. The example configuration will display a menu on the client station. It is possible to select to boot either a Linux kernel, floppy disk image, Linux network installer, diagnostic tool Memtest, or a text mode game Grub Invaders. The chosen bootloader is pxelinux from the syslinux project.

Configuration management for Cisco backbone network
Bartoš, Jan ; Pelka, Tomáš (referee) ; Polívka, Michal (advisor)
The main aim of the master thesis was to create an application for backbone network configuration management. The priority of the application was to be effective and easy to take. Program has to be able to communicate with network devices by remote control and to download and upload configuration files. The program has enable also availability verification for remote control. For this purpose the ICMP protocol was used. The remote control is provided by telnet protocol and the protocol TFTP has been chosen for file tranfers providing. The application is a multithreading application based on the Java programming language. The Java graphic library Swing was used for GUI creation. The application supports file versioning, the configuration of the program can be saved as a text file, which can be easy changed by user. The program and its features are described in the second part of this thesis. The first part deals with theoretical facts about the IP networks and remote control of the Cisco backbone network devices.

Laboratory exercises explaining the principles of network technologies and protocols
Hricko, Tomáš ; Jeřábek, Jan (referee) ; Langhammer, Lukáš (advisor)
The aim of this diploma thesis is to create two exercises for students. The first exercise is concerned with comparison of transport protocols TCP and UDP. The second exercise is concerned with comparison of routing protocols OSPF and RIP. The first part describes used simulation environment. The next part describes the operating system used in routers. The following part describes the procedure of installing virtual machines. The next part consists of theory of protocols TCP, UDP, OSPF and RIP. The last two chapters are the laboratory exercises.

Multicast in IP networks
Petrovský, Peter ; Verner, Lukáš (referee) ; Krkoš, Radko (advisor)
This semestral thesis deals with multicast communication. It explains the principle of multicast data transfer. It also deals with protocol for logging into groups and distributed multicast services. Using TFTP is implemented system for content distribution by multicast communication. It measure and compare the difference between unicast and multicast.

The PXA270M ARM module and its usage as private branch exchange
Vojtíšek, Jindřich ; Šilhavý, Pavel (referee) ; Daněček, Vít (advisor)
This work deals with using the operating system Linux on diskless devices. This is solved on the development kit Voipac PXA270M, which is based on the ARM processor. This work deals further with the distributions of the Linux operating system, which are suitable to use for the device based on the ARM processor. The Linux was chosen because it is one of the most flexible operating systems and the Linux is kept as open source software code, except to the distribution of the Red hat and a few special distributions. The NFS protocol and TFTP are described there. The TFTP and NFS are used to deploy the operating system. It describes there, what are the TFTP and NFS and the principle of their use in computer networks. Practical part is as to, what is needed for the functioning of the TFTP and NFS server on the Ubuntu 11.10 plus how configure them. The OpenOCD is another part of this work. The OpenOCD is designed to work in the device memory. There is shown how to install and run the OpenOCD in order to communicate with the development kit Voipac PXA270M. This work shows how to configure the bootloader U-boot for booting the operating system from the network using the NFS and TFTP. There is described how compile and install PBX Asterisk on Voipac PXA270M with use of cross compiler and how cross compile zlib, OpenSSL and ncurses needed to install nad run Asterisk.

Laboratory exercises explaining network technologies using various simulation instruments
Vaľuš, Dávid ; Ilgner, Petr (referee) ; Bečková, Zuzana (advisor)
This diploma thesis focuses on the preparation of an operating system, a simulation environment and the creation of two laboratory exercises explaining network technologies. In the theoretical part protocols DHCP, FTP, TFTP, HTTP, and NAT service are described. The practical part focuses on the installation of ns-3 and GNS3 programmes and their utilization and settings on OS Ubuntu 18.10. Moreover, it deals with the preparation of laboratory exercises created in the simulation programmes mentioned above together with tutorials, self-check questions and HTTP server in the Python programming language.

Memory Testing on SGI/MIPS Architecture
Rydlo, Karol ; Jaroš, Jiří (referee) ; Kašpárek, Tomáš (advisor)
Work is engaged in making solution for creating own memory tests on graphical station SGI O2. This thesis produces work on MIPS processor architecture and it try to find the ideal environments for testing memory and with it is nearly related looking for chances of start and compile application for SGI O2. Part of my thesis is also target using cross-compilers, for effective and useful work with program for other architecture.

Wisdom and Time Perspective
Topková, Petra ; Lukavská, Kateřina (advisor) ; Pavelková, Isabella (referee)
This diploma thesis is focused on relationship between time perspective and wisdom. The aim of this paper was firstly to transfer Three-Dimensional Wisdom Scale (3D-WS) into Czech environment and test its psychometric properties, and secondly to explore relationships between wisdom conceptualized using above mentioned scale and time perspective. The sample encompassed 196 respondents. In order to measure time perspective Swedish version of the Zimbardo Time Perspective Inventory (S-ZTPI) and the Transcendental-Future Time Perspective scale were used; in order to explore wisdom Czech version of the Three- Dimensional Wisdom Scale was applied. Both newly translated questionnaires showed good psychometric properties in Czech sample. Balanced time perspective was calculated via two different methods and was related to education and health state. Only a very few respondents achieved optimal scores for BTP as well as for wisdom. Czech respondents scored the highest in reflective wisdom dimension and the lowest in the affective wisdom dimension. Women scored higher than men in affective subscale. Wisdom subscales and total wisdom had complex relations with different time perspectives. BTP was posivitely correlated with wisdom. Women scored higher than men in TFTP. This time perspective correlated with...
