Description

Background

A start-up company decides to build its own information system infrastructure to host a web server and a file server for staff home directories. The system has planned as described by the following diagram. It has two internal networks deployed at two locations interconnected by a router that serves as a gateway to Internet as well. The web server and staff desktop(s) are connected to one internal network called intnet-1 and file server is connected to the other called intnet-2. The subnets and IP addresses are proposed as indicated in the diagram.

Task: 

Your task is to implement this plan by building the system and configure the system and networks including the router to meet the following requirements.

20. The router, web and file servers will use Ubuntu Linux 20.04 server as operating systems while the staff desktop will use Ubuntu Linux 20.04 desktop. This is to be simulated with virtual machines using Oracle VirtualBox manager. The host names are router, web, files and desktop as indicated in the diagram. Use your email ID as the username for all machines.
21. The IP addresses will be statically configured as assigned in the diagram except those of the Adapter 1 of the router and the gateway to the outside network/Internet that are assigned automatically via the built-in DHCP server on the VirtualBox virtualisation platform.

• The router server will serve as a NAT router to outside network/Internet and a router for internal networks. It also hosts a DNS service for the domain com for the company internal networks. The company needs to access the web server as www.mycompany.com, the DNS server as dns.mycompany.com and the file server as home.mycompany.com.

1. The web server will host an Apache2 web service. The document root is /www that is mounted to a dataset called /webpool/doc from the ZFS pool webpool made from a VDEV of 2 disks in a

mirror.  Create a simple home page for the assignment on the web server to show information on subject name and code, assignment number, your name, student number and email ID.

1. The files server will host a ZFS pool datapool made from a VDEV of 3 disks configured as double-parity RAID-Z pool. There is a dataset, datapool/home created from the pool. The dataset datapool/home is exported as a NFS share.
2. The desktop machine will mount the /home directory to the NFS share from mycompany.com at boot. This is to be configured in /etc/fstab.

Report

You will create a report and submit it as a PDF document. The report should show information on subject name and code, assignment number, your name, student number and email ID on the first page.

The report contains the following content in sections as indicated.

1. Network configuration
2. A screenshot of the output from the command ip address on the router, web, files and desktop machines, respectively.

For instance,

All your screenshots of output from commands in this report must show the username and hostname as indicated in the exemplar otherwise it will be disregarded and no mark would be given.

(2 marks) 2. Routing configuration

1. A screenshot of the output from the command cat /etc/iptables/rules.v4 on the router
2. A screenshot of the output from the command ping 192.168.1.2 on the files machine and ping 192.168.2.2 on the web machine, respectively.

(2 marks) 3.   DNS service configuration

1. Content of the file /etc/bind/named.conf.local and all forward and reverse zone files.
2. A screenshot of the output from the command dig home.mycompany.com on the web machine and dig www.mycompany.com on the files machine, respectively.

 

 

192. A screenshot of the output from the command dig -x 192.168.2.2

@dns.mycompany.com on the web machine.

(2 marks)

4. File system configuration

 

1. A screenshot of the output from the command zpool status on the web and files machines, respectively.
2. A screenshot of the output from the command zfs list on the web and files machines, respectively.
3. A screenshot of the output from the command showmount -e home.mycompany.com on the desktop
4. A screenshot of the output from the command cat /etc/fstab on the desktop

5. Web service configuration

 

1. A screenshot of the output from the command

cat /etc/apache2/sites-available/000-default.conf on the web machines.

1. A screenshot of your assignment web page on Firefox pointing to mycompany.com on the desktop machine.
