Stress testing of computer networks
Bolek, Daniel ; Martinásek, Zdeněk (referee) ; Hajný, Jan (advisor)
Bachelor's thesis deals with stress testing of server running on operating system Linux. Theoretical part of this project briefly describes the history of Linux, choice of distribution Debian and the server's applications Apache and Vsftpd. Then I describe device Spirent Avalanche 3100, which is designed to generate load and interprets results of tests. Semestral project also deals with DDoS attacks, analyzes current state in this field and describe those DDoS attacks, which provides device Avalanche 3100. Then shows possible solution, how to proceed, if we want to design protection against DDoS attacks. Practical part of semestral project is focused on installation of a operating system Linux, implementation and configuration web, FTP and SSH server services and firewall settings. After that the server is subjected to stress testing. The main aim is to test the success of HTTP and FTP server for different load height and determine, whether size of downloaded file has an effect to response time of the server. The aim of following section is to measure the impact of the choosen DDoS attacks. Protection against SynFlood attack is tested in the last part.
