Title: Network Administration Projects
Criteria for assessment:
1. The network and its services work as intended.
2. The report documents the system and indicates a correct understanding of how the network components fit into the whole.
Note that all screenshots must include the Student Name, e.g., the hostname, email address, or log file entries. Anonymous screenshots and heavy reliance on screenshot fragments that do not show personalization provide insufficient evidence, and the maximum mark for the configuration is 4/10.
Due dates: Week 10: Document Format
All parts of the assignment must be completed using the current Linux distributions: Rocky Linux (Red Hat clone) for the server and Ubuntu for the client configuration.
Task 1:
As a Linux network administrator, you have been assigned the basic task of setting up a fully functional email server using Rocky Linux. Your first step is to ensure that the network configurations are correct.
You are tasked with building a fully operational server system using Rocky Linux within VirtualBox. Your server and clients must have an appropriate configuration for the network settings such as FQDN, Static IP address, DNS, and DHCP. Please note that you are not required to document all the mentioned network settings for the assignment.
Once the network is up and running, your first task for this assignment is to install and configure Postfix as the Mail Transfer Agent (MTA) and Dovecot as the IMAP/POP3 server. These services will allow users to send and receive emails using third-party applications such as Thunderbird.
In addition to basic email functionality, the security of the communication is paramount. You are required to implement SSL/TLS encryption for secure email transmission and retrieval. By configuring SSL/TLS for both Postfix and Dovecot, you will ensure that users can communicate securely, protecting sensitive information during email exchanges. Once the setup is complete, you are expected to test the system by sending and receiving emails between users and verifying that the secure connections are functioning properly.
Note: For the assignment, you must install VirtualBox on your machine and create two virtual machines: one running Rocky Linux (server) and the other running Ubuntu Linux (client).
General Guidelines and steps for email server:
· Install Postfix
· Configure Postfix
· Install Dovecot
· Configure Dovecot
· Install open SSL or any other SSL program.
· Restart Services
· Set Up Mozilla Thunderbird
· Provide evidence of successful secure email between client and server.
· Troubleshooting and Test Email
Task 2:

Submission Requirements
1. Online submissions via Moodle. Separate submission links will be provided in Moodle.
2. Submissions must be in Microsoft Word format with Times New Roman font size 12 and 1.5 line spacing justified.
3. Submissions need to be well presented. Submissions that are unprofessional in their look (disorganized, inconsistent, not in chapters/sections) will not fare well when marks are allocated.
4. Every submission must have a front cover. The front cover should have the following details:
a) Name(s) /and TP number(s)
b) Intake code, Module code, and name
c) Submission title
d) Date assigned (the date the submission was handed out)
e) Date completed (the date the submission is due to be handed in)
5. All information, figures, and diagrams obtained from external sources must be referenced using the APA referencing system accordingly.
Important Note:
Document the results of your work professionally and systematically in the form of online submissions via Moodle.
Use the provided cover page as your cover. Only one group member should upload the file to Moodle as the assignment submission.
