Author: Rand Deeb / Information Security master student / ITMO University

This repository is a practical project in ITMO University

Task1:

Task name:

Manage GitHub scripts and documents

Task preparation:

create Skills2022 directory inside the home directory using mkdir

Task implementation

1. Create Skills2022 directory
2. Initialize the local repository, Create README.md file and add it to the repo.
3. Create remote repo and add remote origin
4. Had the error Password support removed and solve it using the following commands after create personal access token (explained in details in task troubleshooting).
5. push the commits to the remote repo using push command

Task troubleshooting

We can create access token from your GitHub account, go to Settings => Developer Settings => Personal Access Token => Generate New Token (Give your password) => Fillup the form => click Generate token => Copy the generated Token then use the following commands as in the step5 screenshot

$ git config --global user.name "your_github_username"
$ git config --global user.email "your_github_email"
$ git config -l

Task2:

Task name:

Manage WebServers through Ansible.

Task preparation:

• Create task2 directory inside the Skills2022 directory using mkdir
• Enable the SSH server

Task implementation

1. Copy Desktop/labs/devnet-src/ansible/ansible-apache files to Skills2022/task2
2. Add the following to hosts file

[webservers] 
192.0.2.3 ansible_ssh_user=devasc ansible_ssh_pass=Cisco123!

3. Add the following to ansible.cfg config:

[defaults]
# hosts
inventory=./hosts 
# RSA
host_key_checking = False
# retry files
retry_files_enable = False

3. Add the following to the playbook file:

- hosts: webservers 
  become: yes 
  tasks: 
    - name: INSTALL APACHE2 
      apt: name=apache2 update_cache=yes state=latest 
  
    - name: ENABLED MOD_REWRITE
      apache2_module: name=rewrite state=present 
      notify: 
        - RESTART APACHE2 
  
    - name: TESTING
      command: /bin/echo test
  
  handlers: 
    - name: RESTART APACHE2 
      service: name=apache2 state=restarted

Run and wait, it will clone the repo and execute the setup&run script and you will notice the success sign

Task5:

Task name:

Unit testing

Task preparation:

create task5 directory inside the Skills2022 directory using mkdir

Task implementation

1. Create task.py file contains the functions which we need to test:

def factors(n):
  p = 2
  f = list()
  while n >= p*p :
      if n % p == 0:
          f.append(p)
          n = int(n / p)
      else:
         p = p + 1
  f.append(n)
  return f

def is_prime(number):
  if number <= 1:
      return False
  for n in range(2, number):
      if number % n == 0:
          return False
      else:
          return True

def vowels(text):
  v = list()
  for i in text:
      if i in 'aeiouAEIOU':
          v.append(i)
  return v

2. import unittest

import  unittest

3. Add test class which inherits unittest.TestCase
4. Convert the test functions into methods by adding self as the first argument

class TestTask5(unittest.TestCase):
    def test_factors(self):
        self.assertCountEqual(factors(1), [1], "Should be [1]")
        self.assertCountEqual(factors(4), [2, 2], "Should be [2,2]")
        self.assertCountEqual(factors(5), [5], "Should be [5]")
        self.assertCountEqual(factors(6), [2,3], "Should be [2,3]")

    def test_is_prime(self):
        self.assertEqual(is_prime(-1), False, "Should be False")
        self.assertEqual(is_prime(1), False, "Should be False")
        self.assertEqual(is_prime(4), False, "Should be False")
        self.assertEqual(is_prime(5), True, "Should be True")
        self.assertEqual(is_prime(6), False, "Should be False")

    def test_vowels(self):
        self.assertCountEqual(vowels("ok"), ["o"], 'Should be ["o"]')
        self.assertCountEqual(vowels("test"), ["e"], 'Should be ["e"]')
        self.assertCountEqual(vowels("aeiouAEIOU"), ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"], 'Should be ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]')
        self.assertCountEqual(vowels(""), [], "Should be []")

    def test_len(self):
        self.assertEqual(len(""), 0, "Should be 0")
        self.assertEqual(len("test"), 4, "Should be 4")
        self.assertEqual(len("test "), 5, "Should be 5")
        self.assertEqual(len([1, 2]), 2, "Should be 2")
