Network System Administration Report: DNS, DHCP, SSH, and Iptables

This report delves into network system administration, aiming to improve the performance of an existing network system through a new design implemented using Linux network services. The project involves the installation and configuration of DHCP and DNS servers, SSH securing, and iptables. It explores client/server configuration, QoS implementation, and virtual hosts. The report provides experimental work and analysis, including detailed steps for setting up and testing these network components. The report also discusses project scope, limitations, and concludes with an evaluation of the implemented design, offering insights into how the proposed network design enhances the overall network performance and security. The study emphasizes the importance of network administration, addressing common network issues and the need for effective configuration and security measures.
