A File System Implementing Storage for Gentoo Portage Based on a Relational Database
Štulpa, Adam ; Mlích, Jozef (referee) ; Rychlý, Marek (advisor)
The thesis deals with implementation of a program which can, through the use of FUSE library, make data accessible in the relational database like the classical Gentoo Portage storage. First, the reader of the thesis becomes familiar with FUSE library itself. After that, the new data model is built based on the analysis of the Portage structure. The new model emphasizes especially dependencies of packages. The key implementation issues are also described in the next part. Finally, the thesis assesses outcomes achieved including comparison with standard Portage implementation and classical file system. The other possibilities of the project development are considered as well.

System for controlling optical fiber amplifier modules
Matoušek, Jan ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
This diploma thesis deals with the design of the telecommunication device for optical amplifiers and the implementation of the universal software for thecommunication with an optical amplifier. An universal control interface has been created to control modules remotely via the SSH remote access or via the LCD display and buttons on the device. The Linux security is listed in this thesis. The device was designed in the 1U case, where the front and rear panels and the arrangement of elements inside were designed. Subsequently, the functionality of the device and the communication with the LCD display and the optical module were tested.

Establishment of the Linux internet gateway using advanced filtering
Matocha, Tomáš ; Pust, Radim (referee) ; Jelínek, Mojmír (advisor)
The thesis Establishment of the Linux internet gateway using advanced filtering focuses on~the installation of~the Linux operating system on~the older computers, that functions as a gateway to connect clients in the internal network to the Internet. The thesis describes creation an advanced filter with using iptables. Shows some types of security against attacks from the Internet. The other chapters are discussed, advanced traffic control mechanism (such as a TC and a qdisc). The system queue, it is highly beneficial where it is necessary to hierarchically divide traffic between users. It describes types of queue and assembled configurations for clients in the internal network. Next chapter describes the DNS server caching-only type and application denyhosts, which increases the overall security system. Have your own DNS server is certified, especially if we want to reduce the data traffic. Last chapter describes the RADIUS server and its implementation using Apache and MySQL database. Furthermore, the configuration options are described and the examples of the particular configurations are provided. Finally, it presented a system for authentication through the RADIUS server. The thesis seeks to provide a~complex view of security and filtering.
