Answer available — download the full PDF for complete details.

QQ1. Shell Scripting (Linux/UNIX)

(a)) Write a shell script named backup.sh that performs the following tasks: 1. It should accept a source directory path and a destination directory path as command-line arguments. 2. It should check if the source directory exists. If not, it should print an error message and exit. 3. It should create a compressed backup of the source directory in the destination directory. The backup filename should be in the format backup_YYYY-MM-DD.tar.gz (e.g., backup_2025-10-25.tar.gz). 4. After a successful backup, it should print a message: "Backup of [source_directory] completed successfully at [destination_path/backup_filename]". (250 words)
(b)) Write another shell script named user_check.sh that takes a username as input. The script should check if the given user is currently logged into the system. If the user is logged in, it should display: "[Username] is currently active on the system." If the user is not logged in, it should display: "[Username] is not logged in." (250 words)

Key Points:

Shell scripts automate tasks using sequences of Linux commands.
`tar -czf` creates a gzipped tar archive for directory backups.
`date +%Y-%m-%d` formats the current date for timestamped filenames.
`if [ -d "$DIR" ]` checks for the existence of a directory.

Answer:

QQ2. Linux/UNIX System Administration Perform the following system administration tasks. For each task, write the exact command(s) you would use and provide a brief explanation of what the command does.

(a)) Create a new user account named intern with /home/intern as their home directory and /bin/bash as their default shell. (125 words)
(b)) Create a new group named devteam. Add the user intern and an existing user manager to this new group. (125 words)
(c)) Create a directory named /project/data. Change its ownership so that the user manager is the owner and the group devteam is the group owner. (125 words)
(d)) Set the permissions for the /project/data directory such that: * The owner (manager) has read, write, and execute permissions. * Members of the devteam group have read and execute permissions only. * Other users have no permissions at all. (125 words)

Key Points:

The `useradd` command creates new user accounts, specifying home directories (`-d`) and default shells (`-s`).
The `groupadd` command creates new user groups for organizing permissions.
The `usermod -aG` command adds users to supplementary groups without removing existing memberships.
The `mkdir -p` command creates directories, including parent directories if they don't exist.

Answer: Linux/UNIX system administration is a fundamental skill in managing servers and workstations, ensuring proper user access, resource allocation, and security. The tasks outlined below demonstrate core administrative functions such as user and group management, directory creation, and permission assignment, which are crucial for maintaining a multi-user environment as taught in BCSL-063. These operations are typically performed with superuser privileges (e.g., using `sudo`) to modify system-wide ...

QQ3. Windows Server Administration Provide a step-by-step procedure with screenshots for the following tasks in a Windows Server environment.

(a)) Create and Configure a New User: 1. Open "Active Directory Users and Computers". 2. Create a new user with the following details: Full Name: Riya Sharma User logon name: riya.s 3. Set a password for the user and configure the account so that the "User must change password at next logon". 4. Add this new user to the "Marketing" group (assume the group already exists). (250 words)
(b)) Create a Shared Folder: 1. Create a new folder named MarketingReports on the C: drive. 2. Share this folder with the network name Marketing_Share. 3. Configure the share permissions so that the "Marketing" group has "Full Control". 4. Configure the NTFS permissions so that the "Marketing" group has "Modify" permissions, and the "Administrators" group has "Full Control". (250 words)

Key Points:

Active Directory Users and Computers is used to manage user accounts and groups centrally.
User creation involves defining full name, logon name, and setting initial password policies.
The 'User must change password at next logon' option enforces immediate password customization for security.
Adding users to groups (e.g., 'Marketing') simplifies permission management for shared resources.

Answer: Windows Server Administration involves managing user accounts and shared resources efficiently. This often includes tasks such as creating new user accounts within Active Directory and configuring shared folders with appropriate permissions. These steps are fundamental to maintaining a secure and organized network environment, ensuring that users have access to necessary resources while restricting unauthorized access. Understanding the distinction between share permissions and NTFS permissions ...

QQ4. Network Configuration and Services Provide a step-by-step procedure with screenshots to perform the following network configurations.

(a)) Configure a Static IP Address (Windows): Configure a network adapter in Windows with the following static IP settings: IP Address: 192.168.1.50 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.1 Preferred DNS Server: 8.8.8.8 (250 words)
(b)) Install and Configure a Basic DHCP Server (Windows Server): 1. Install the DHCP Server role on your Windows Server. 2. Create a new IPv4 scope with the following details: Scope Name: Office_Network Start IP Address: 192.168.1.100 End IP Address: 192.168.1.200 Subnet Mask: 255.255.255.0 Router (Default Gateway): 192.168.1.1 DNS Server: 8.8.8.8 3. Activate the scope. (250 words)

Key Points:

Static IP configuration involves manual entry of IP, Subnet Mask, Gateway, and DNS.
Access network adapter properties (TCP/IPv4) to set static IP addresses.
DHCP server role provides automated IP address assignment to network clients.
DHCP scope defines the range of IP addresses and network configuration options.

Answer: Network configuration and service management are fundamental aspects of operating system networking. This lab exercise focuses on two critical configurations: assigning a static IP address to a client machine and setting up a Dynamic Host Configuration Protocol (DHCP) server on a Windows Server. These procedures ensure proper network communication and efficient IP address management within an organizational network, as detailed in the BCSL-063 course material. Setting a static IP provides a per...

QQ5. Linux/UNIX Command-Line Tasks Write the single-line command to perform each of the following tasks in a Linux/UNIX terminal.

(a)) Find and display all lines in the file /var/log/syslog that contain the word "error" (case-insensitive). (100 words)
(b)) List all running processes on the system and find the Process ID (PID) of the apache2 process. (100 words)
(c)) Create a symbolic link named webapp in your home directory that points to /var/www/html. (100 words)
(d)) Display the disk space usage of all mounted file systems in a human-readable format (e.g., KB, MB, GB). (100 words)
(e)) Schedule a job using cron to run the script /home/user/maintenance.sh at 2:00 AM every Sunday. (100 words)

Key Points:

Use `grep -i "pattern" file` for case-insensitive search in files.
`ps aux | grep "process" | grep -v "grep"` finds process PIDs.
`ln -s target linkname` creates a symbolic link.
`df -h` shows disk usage in human-readable units.

Answer: Linux/UNIX command-line tasks are fundamental for system administration, offering powerful and efficient ways to manage files, processes, disk space, and schedule automated jobs. The ability to execute these tasks using single-line commands highlights the flexibility and robustness of the shell environment. Each command provides a specific utility designed to interact directly with the operating system's core functions. These commands are essential for diagnostics, system maintenance, and autom...
