Hackers usually perform an initial reconnaissance and probing scan to identify IP hosts‚ open ports‚ and services enabled on servers and workstations. In this lab‚ you planned an attack on 172.30.0.0/24 where the VM server farm resides‚ and used the Zenmap GUI to perform an “Intense Scan” on the targeted IP subnetwork.

Gnutella is among the most popular P2P systems. This chapter presents a broad overview of P2P computing and concentrates on Gnutella I in the context of Web Services discovery. It also emphasizes on the analysis of a revised mechanism that can achieve the ping pong message exchange objectives but with less network traffic. In addition‚ these chapters also suggest method in detail and provide lines of reasoning as to why it could. 1.0 INTRODUCTION Gnutella is a communications protocol for distributed
