Abstract
Computing and information infrastructures involves high level of complexity which are
dynamic in nature. This is due to minimal measures to the proliferations of networking
technologies. Linux network sub-system is somehow complex as compared to other operating
system as it implements a large number of protocols. Different from other operating systems,
Linux operating systems is monolithic kernel based where the entire functionality is concentrated
in one large kernel. This report will show how one can design a suitable network in Linux.
Introduction
Network design is the backbone of any company or organization. A good network design
will provide one with a strong basis for conducting Quality of Service troubleshooting and
monitoring. How well a network functions determines how one devices communicate with each
other. Debian Linux provide one of the best network system services. Some of the best services
provided by Linux are DHCP server services, DNS services, and firewall services (Adelstein &
Lubanovic, 2015, p. 38).
Background information
Network services in Linux and other Operating systems are a set of applications which
run in the background. There are three services which are required for network activities in a
Linux system. These are; network, iptables, and xinetd. The network service turns on network
card and powers the modem. The iptables is kernel based packet filtering firewall service. Most
