OPS535 Lab 2 (using Virutal Lab)
Objectives
- Setup and configure private network for your assigned VMs in the OPS535 Virtual Lab for this lab, future labs, and assignments
- Configure VM1 as your control workstation for performing remote administration tasks on VM[2-4]
- Create and deploy remote administration scripts using bash/ansible
Pre-Requisites
- Has access to Seneca VPN, and matrix.senecacollege.ca
- Complete the collection of baseline information on your assigned VMs (VM1, VM2, VM3, and VM4)
- Complete the Lab 2 - NFS lab on your home VMs
Investigation 1: VMs Configuration
Background
You have ssh access to your assigned VMs from matrix.senecacollege.ca using the port numbers, user name, and the corresponding password given on Blackboard via the router ops535.myvmlab.senecacollege.ca. The access router will map the ports (9xxy) to the corresponding internal IP addresses (172.20.xx.y) of your VMs, where 'xx' is you assigned network number, and 'y' is the VM number. The following are the port mapping and the network interfaces on each VM:
| VM | Port | ens192 ip | ens224 ip | ens256 ip |
| VMy | 9xxy | 172.20.xx.y | 192.168.xx.y | ---- |
| VM1 | 9141 | 172.20.14.1 | 192.168.14.1 | do-not-use |
| VM2 | 9142 | 172.20.14.2 | 192.168.14.2 | none |
| VM3 | 9143 | 172.20.14.3 | 192.168.14.3 | none |
| VM4 | 9144 | 172.20.14.4 | 192.168.14.4 | none |
Task 1 : setup and configure VM1
- ssh to your VM1 from matrix
ssh -p 9141 student@ops535.myvmlab.senecacollege.ca
- confirm the IP address on the network dev 'ens192'.
- run the 'nmtui' command under sudo and configure ens224 with the appropriate IP address (192.168.xx.1) as shown.
- install the 'epel-release' package
- install the 'ansible' package
- install the 'git' package
- install the 'wget' package
- configure ssh key-based access from your VM1 to VM[2-4] for the 'student' account.
Task 2: setup and configure VM2 - VM4
- you can either ssh to your VM2 - VM4 from matrix or from your VM1.
- ssh to your VM2 - VM4 from matrix, replace [2-4] with 2, 3, or 4:
ssh -p 914[2-4] student@ops435.myvmlab.senecacollege.ca
- ssh to your VM2 - VM4 from your VM1
ssh 172.20.14.[2-4]
Investigation 2: Control Workstation Configuration
Perform the following steps on VM1 as root:
Investigation 3: Scripts for remote administrations
Task 1
Using bash scripts
Task 2
Using Ansible Playbooks
Completing the Lab
Follow the instructions on blackboard to submit the lab.
