All job should be done on Linux server ubuntu. I indicated page number based on words. It will probably more pages as most of it will be filled with screenshots 1) You are required to configure and test a DNS server (Ubuntu Server 16.04.3 LTS). Configure a DNS server with both forward and reverse lookup. You should configure a domain name zone of itc333.edu, and a reverse name mapping zone of 192.168.15.0/24. Configure A and PTR records for: host1 – 192.168.15.10, host2 – 192.168.15.11 and host3 – 192.168.15.12. Configure a CNAME of www for host1, and a CNAME of dc1 for host2. Test the operation of your DNS server using an external client running DNS queries. [10 marks] 2) Create a user “assgn2′ and in their home directory create the files with the following permissions [5 marks]. • A file called “test.txt”, with contents “This is a test file”, with read and write permissions for owner, group and other, but no execute permissions. • A file called “script1” that runs a simple script of your choosing, with read and execute permissions for group and other, and full read, write and execute permissions for the owner. • A hidden file called “.test_config”, owned by root with contents “Test config file”, that has root read, write and execute permissions only, no other permissions set. • A symbolic link with an absolute path to a system log file of your choosing. • A directory called “test_dir” with the owner having full permissions to create, rename or delete files in the directory, list files and enter the directory. Group and other having permissions to only list files and enter the directory and access files within it. Submit a learning diary for this activity in which you should include: • Your DNS configuration, including copies of your underlying DNS server configuration files; • Screenshots from your client device demonstrating the operation of the DNS server; • What you did; • Describe the problems you encountered. Were you able to resolve these problems? (Y/N); • How much time you spent on each part of the exercise. Rationale This assessment item is design to test your • assess your progress towards meeting subject learning outcomes 1, 2 and 3; • assist you to develop your learning of the priciples covered in topics 1-6 of the subject; • knowledge of the details of network service technologies; • ability to apply problem-solving techniques; • ability to find credible information sources and apply them; • ability to write clearly and concisely; and • ability to correctly reference information sources. Marking criteria Part 1. This part is a series of multiple choice questions. Each correct answer will score 1 mark. Marks will not be deducted for incorrect answers.
