Assignment #$1$: Build a Small Linux Network Scenario

XYZ is an upstart company located in Calgary. They need a network designed and implemented by a Linux administrator: They have contracted you to set up their infrastructure with basic configurations and server services using $2$ RedHat Enterprise Linux Servers. One server must be configured with appropriate files, folders, users, groups and permissions. A second Linux$-$based server will provide DHCP$,$

and DNS services.

The company has three departments: Sales, Human Resources and Engineering, and they have hired six new employees to fill the three newly designed departments. As a Linux administrator, you are responsible to ensure a successful launch of the newly designed departments and the company.

Requirements

$$ Follow logical and appropriate naming conventions for virtual machine hostnames.

$$ Use a static IP address, subnet mask and default gateway for all servers.

$$ Set up and configure a Linux DHCP server to automatically assign IP addresses to client machines.

$$ Set up and configure a Linux DNS server capable of resolving hostnames of all machines on your network to IP addresses and vice versa.

$$ Enable firewall service to allow http traffic.

$$ Create a directory at the root of the file system for each department with the name reflecting their department name.

$$ Create a group for each department with the name reflecting their department name.

$$ Create an administrator user for each department. The user will belong to the respective group for each department. You can create your own user names.

$$ Only the owner of a file in the department's directory can delete the file.

$$ Create a document in each of the department directories with the following text: "This is a confidential document created by $[$your name$]."$ This document can be read by anyone in the department but can only be modified by the administrator of the department."

$$ All machines must be able to ping each other by hostname and IP address.

$$ All machines must have access to the internet.

$$ All client machines will receive IP addressing dynamically from a DHCP server.

The DHCP$/$DNS server will use the ip address $10\mathrm{.}10\mathrm{.}10\mathrm{.}1/24$

The client will use the ip address $10\mathrm{.}10\mathrm{.}10\mathrm{.}2/24$

There will be $1$ sudo user for all systems, $3$managers$(1$ for each department$)$ and $2$ regular users in each department.

A group must be created for all departments using the department name.

An administrator user account is created for each department and the user belongs to its respective department group

A directory is created at the root of the file system for each department using the department name $.$

Can you provide the commands to do all the above and a step by step guide to do it right?
