This master's thesis is meant to provide techniques in designing and building a standalone packet filtering firewall in Linux machines, mainly for small sites who don’t give much service to Internet users. It deals with attenuating the effect of the most common types of attacks using iptables. It guides how to design, implement, run, and maintain Firewall. Techniques for continuously monitoring attacks is attempted. It also give a historical, architectural and technical overview of firewalls and security attacks.

The Master’s thesis ”The Implementation of the Advanced Filtering Based on the Packets’ Classification using Linux” is intended to the realization of an internet gateway. The gateway serves to make the connection between local network and the internet. The thesis contains a short theoretic description of parameters and types of QoS services. The classful and classless queues are mentioned in detail. The last theoretic part refers to the introducing of LDAP protocol and its usage. The practical part of this thesis captures the configuration of firewall, dns and radius server connected with LDAP databases. The thesis also contains detailed description of the production QoS by HTB with L7-filter including the compilation of system’s core. The end of the thesis contains the series of tests of created scripts.

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.

Táto práca sa venuje probému prepojovania rôznych typov sietí, konkrétne sietí typu IEEE 802.15.4 a Ethernetu. Motivácia vychádza zo stále sa rozširujúceho využitia bezdrátových senzorických sietí, potreby zberu dát z nich a ich integrácie. To vyžaduje aby sieť obsahovala prvky schopné preniesť dáta z bezdrátovej siete do okolitého sveta a prípadne poskytnúť konfiguračné a riadiace informácie do vnútra siete. Z hľadiska protokolov a programového vybavenia sa prepojenie uskutočňuje na rôznej úrovni, od sieťovej až po aplikačnú vrstvu komunikačného modelu ISO/OSI, s podporou hardvéru na fyzickej a linkovej vrstve.

This thesis deals with the management of computer servers. The theoretical part describes the client-server architecture, operating system GNU/Linux and server management tools. The second chapter is devoted to design an own application to manage servers. The next chapter describes the design and implementation of individual modules from which application is build. In the fourth chapter there is described how to install and configure the application on the GNU/Linuw operating system. The penultimate chapter is written as a user manual and acquaints reader with application control. In the last section there are results obtained in testing the application presented and commented.

This thesis presents principles of transmission of digital television broadcasting via satellite placed in orbit of Earth. It also focuses on the satellite receiver as an important part of satellite systems. It mention receiver’s firmware and deals with design and implementation of satellite receiver’s application.  The aim is to create an application that will personalize satellite receiver by monitoring TV stations that have been watched.

The master's thesis is about a communication element - a hardware module, its design and implementation. The communication is to be maintained between a Linux embedded device and the sensors elements, using the MiWi protocol. The task is part of the IoT project, developed at FIT BUT. Furthermore, the paper describes design of a driver for the module, its likely solution, as well as the very implementation. Finally, the obtained experience is discussed in a summary, along the next step options on how to proceed further with the driver development.

This work describes a novel approach of HW/SW codesign on the Xilinx Zynq and similar platforms. It deals with interconnections between the Processing System (ARM Cortex-A9 MPCore) and the Programmable Logic (FPGA) to find an abstract and universal way to develop applications that are partially offloaded into the programmable hardware and that run in the Linux operating system. For that purpose a framework for HW/SW codesign on the Zynq and similar platforms is designed. No such framework is currently available.

This work deals with indexing, difeerent types of indexing structures their advantages and disadvantages. It provides the basis for a search engine with support of morphology or difeerent file formats. Provides insight to the basic ideas, which answer is aim of the master's thesis.

Tato práce navrhuje dotykové uživatelské rozhraní pro elektromobily. Rozhraní bylo navrženo tak, aby bylo pohodlné na použití pro řidiče a aby bylo snadné z něj vyčíst potřebné informace. Aby bylo možné toto rozhraní integrovat do elektromobilu, tato práce také navrhuje potřebnou softwarovou a systémovou (hardwarovou) architekturu. Nakonec shrnuje co je ještě potřeba udělat, aby bylo možné celý systém integrovat.
