Big Block File System
Rajman, Jakub ; Lampa, Petr (referee) ; Čejka, Rudolf (advisor)
Master's thesis treats of implementation of big block file system for FreeBSD operating system. The introduction of this document is dedicated to theoretically analysis, which is oriented on history, sense and usage of file systems. Next chapter describes the architecture of UFS/FFS file system. Implementation part starts with introducing design of new file system, which was isnpired by MSDOSFS file system. Last part of this thesis presents implementation of file system with great emphasis on problems, which can happen during programming.

Email Filtering Administration in Roundcube
Španěl, Tomáš ; Lampa, Petr (referee) ; Dytrych, Jaroslav (advisor)
The aim of this work is to create a plug-in for the Roundcube webmail, which allows the management of filters for incoming mail and automatic absence notification, where the Procmail tool is used for the filtering itself. The work also examines how to generate these filters and report the absence and their comprehensive presentation to the user within the Roundcube. The result of the work is a functional plug-in module and a description of interesting passages from its implementation.

Linux OS Monitoring
Korček, Juraj ; Očenášek, Pavel (referee) ; Trchalík, Roman (advisor)
The aim of this bachelor's thesis is design and implementation of monitoring tool for GNU/Linux operating systems. This program monitors logs created by system, system load and computer resources. It notifies system administrator in case of high system load, abnormal behavior or when an error occurs. The resulting product is especially aimed for system administrators of GNU/Linux, whose work will be simplified due to this software utility, which sends notification of only important system changes. It is implemented in scripting language Python and divided into smaller independent scripts for easy implementation of new scripts in the future. This programming language was chosen to ensure operation among all GNU/Linux distributions.

Acquisition of data on network communication from terminal devices
Obršlík, Lukáš ; Šedý, Jakub (referee) ; Krkoš, Radko (advisor)
The bachelor’s thesis deals with collecting statistical information about network communication in terminal equipment devices. Theoretical part of this project aims to gather methods and application tools on Windows and Unix platforms and support them by well chosen third party solution to gain more detailed informations. Tools were chosen based on ease of deployment and usage. Practical part of bachelor’s thesis directs to find suitable solution to gather detailed informations about network traffic. Important fact must be to not bother the end-users. Next part is to develop own application for collecting information about network usage and communication. Output format structure of the solution was designed with future data manipulation in mind.

System for Parallel Processing of URL Requests
Horáček, Jan ; Matoušek, Petr (referee) ; Ráb, Jaroslav (advisor)
The work treats of programming multithreaded application, focused on processing the demands for URL calling. The application was programmed in the ANSI norm of the language C. It runs as independent daemon, which must faciliate, in maximum possible scale, searching for demands, which weren't successfully processed. For URL calling it uses the library libCURL and installing in station of package autotools.
