Wireshark Lab: DNS Version: 2. 0 © 2007 J. F. Kurose, K. W. Ross. All Rights Reserved Computer Networking: A Topdown Approach, 4 th edition. As described in Section 2. 5 of the textbook, the Domain Name System (DNS) translates hostnames to IP addresses, fulfilling a critical role in the Internet infrastructure. In this lab, we’ll take a closer look at the client side of DNS. Recall that the client’s role in the DNS is relatively simple – a client sends a query to its local DNS server, and receives a response back. As shown in Figures 2. 21 and 2. 22 in the textbook, much can go on “under the covers,” invisible to the DNS clients, as the hierarchical DNS servers communicate with each other to either recursively or iteratively resolve the client’s DNS query. From the DNS client’s standpoint, however, the protocol is quite simple – a query is formulated to the local DNS server and a response is received from that server. Before beginning this lab, you’ll probably want to review D

POLIT´ECNICO GRANCOLOMBIANO FACULTAD DE INGENIER´IA Y CIENCIAS B´ASICAS 3er CONCURSO ROBOCODE - POLIT´ECNICO GRANCOLOMBIANO La facultad de Ingenier´ıa y Ciencias B´asicas invita a toda la comunidad acad´emica del Polit´ecnico Grancolombiano: estudiantes, directivos, egresados, docentes, personal administrativos y funcionarios de la instituci´on a participar en el tercer torneo de Robocode - Polit´ecnico Grancolombiano. Condiciones generales del concurso: El concurso de Robocode es una competencia por equipos de m´aximo dos integrantes cada uno. Los equipos deben participar con un s´olo robot, el cual debe ser entregado al comite organizador a m´as tardar el 19 de octubre del 2011. ¿Qu´e es Robocode? Robocode es un programa de computador en el que en una arena compiten varios robots por sobrevivir, ganando el que al final quede. El comportamiento y estrategia del robot lo define previamente el usuario (competidor) mediante instrucciones en lenguaje Java. Cada batalla

Wireshark Lab: HTTP Version: 2. 0 (June 2007) © 2007 J. F. Kurose, K. W. Ross. All Rights Reserved Computer Networking: A Topdown Approach, 4 th edition. Having gotten our feet wet with the Wireshark packet sniffer in the introductory lab, we’re now ready to use Wireshark to investigate protocols in operation. In this lab, we’ll explore several aspects of the HTTP protocol: the basic GET/response interaction, HTTP message formats, retrieving large HTML files, retrieving HTML files with embedded objects, and HTTP authentication and security. Before beginning these labs, you might want to review Section 2. 2 of the text. 1. The Basic HTTP GET/response interaction Let’s begin our exploration of HTTP by downloading a very simple HTML file - one that is very short, and contains no embedded objects. Do the following: 1. Start up your web browser. 2. Start up the Wireshark packet sniffer, as described in the Introductory lab (but don’t yet begin pa

Wireshark Lab: Getting Started Version: 2. 0 © 2007 J. F. Kurose, K. W. Ross. All Rights Reserved Computer Networking: A Topdown Approach, 4 th edition. “Tell me and I forget. Show me and I remember. Involve me and I understand. ” Chinese proverb One’s understanding of network protocols can often be greatly deepened by “seeing protocols in action” and by “playing around with protocols” – observing the sequence of messages exchanged between two protocol entities, delving down into the details of protocol operation, and causing protocols to perform certain actions and then observing these actions and their consequences. This can be done in simulated scenarios or in a “real” network environment such as the Internet. The Java applets that accompany this text take the first approach. In these Wireshark labs1 , we’ll take the latter approach. You’ll be running various network applications in different scenarios using a computer on your desk, at home, or in a lab. You’ll observe th
