SYSTEM ADMINISTRATION

A SME company decides to rebuild 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. (You will need to use 4VM to construct the above system. Hence, you may clone your server VM and reconfigure hostname and NIC 's MAC address to a new MAC address. You may clone them from a snapshot that you took in the first lab. You may reduce the VM specif) i. 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 (or any lightweight Ubuntu-based or Debian-based Linux such as Lubuntu, Puppy Linux or Antix). This is to be simulated with virtual machines using Oracle VirtualBox (or VMware if VirtualBox is not working on your machine). The host names are router, web, f1les and desktop as indicated in the diagram. Please change the host name of your VMs accordingly. Use your email ID as the username for all machines Gou will need to create a new user and allow the "sudo" for this user account on all machines). ii. 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. iii. 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 "your_last_name". com for the company internal networks. The company needs to access the web server as www. your_last_name. com, the DNS server as dns.your_last_name.com and the file server as home. your_last_name. com. (Replace all your_last_name with your last name) iv. The web server will host an Apache2 web service. The document root is / wwW that is mounted to a dataset called webdevpool/doc from the ZFS pool webdevpool 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. v. The files server will host a ZFS pool filepool made from a VDEV of 3 disks configured as double-parity RAID-Z pool. There is a dataset, filepool/home created from the pool. The dataset filepool/home is exported as a NFS share. vi. The desktop machine will mount the /home directory to the NFS share from home. your_last_name.com at boot. This is to be configured in /etc/fstab. 5. Web service configuration a. A screenshot of the output from the command cat /etc/apache2/sites-available/000-default. conf on the web machines. b.
