ITC514 Practical: Configuring DNS Server and Managing File Permissions

This assignment solution details the configuration and testing of a DNS server, including both forward and reverse lookup zones for the domain .itc514.edu and the reverse zone 192.168.10.0/24. It involves setting up A and PTR records for host1, host2, and host3, along with CNAME records. The solution demonstrates the use of Linux commands to update the system, install DNS server software (bind9), and configure the DNS server's options, local files, and zone files. The solution also covers the creation of a user, setting up file permissions (read, write, and execute), and creating a hidden configuration file with specific permissions. Furthermore, it includes the creation of a symbolic link to a system log file and a directory with controlled access. The document also includes a learning diary with details about the encountered problems, solutions, and time spent on each part of the assignment.

1) You are required to configure and test a DNS server. Configure a DNS server with both forward and
reverse lookup. You should configure a domain name zone of <your_surname>.itc514.edu, and a
reverse name mapping zone of 192.168.10.0/24. Configure A and PTR records for: host1 -
192.168.10.5, host2 - 192.168.10.6 and host3 - 192.168.10.7. Configure a CNAME of www for host1,
and a CNAME of srv_file for host2. Test the operation of your DNS server using an external client
running DNS queries. [10 marks]
