    Study Notes

    System Administration

    • System administration involves managing and maintaining computer systems, including installing, configuring, and troubleshooting.
    • Key tasks:
      • User management: creating and managing user accounts, groups, and permissions.
      • System configuration: configuring system settings, such as network settings and security policies.
      • Performance monitoring: monitoring system performance, identifying bottlenecks, and optimizing system resources.
      • Backup and recovery: creating backups, restoring data, and recovering from system failures.

    Ubuntu

    • Ubuntu is a popular Linux distribution, known for its user-friendly interface and ease of use.
    • Key features:
      • Debian-based package management system (apt-get).
      • GNOME desktop environment.
      • Large community of users and developers, providing extensive support and resources.
      • Regularly updated with new releases and security patches.

    vi Editor Commands

    • Basic commands:
      • i: enter insert mode.
      • esc: exit insert mode and return to command mode.
      • :wq: save and quit.
      • :q!: quit without saving.
    • Navigation:
      • h, j, k, l: move left, down, up, and right.
      • w, b: move forward and backward one word.
      • 0, $: move to beginning and end of line.
    • Editing:
      • x: delete character under cursor.
      • dw: delete word under cursor.
      • p: paste text from buffer.

    Permissions

    • Linux permissions control access to files and directories.
    • Three types of permissions:
      • Read (r): ability to view file contents.
      • Write (w): ability to modify file contents.
      • Execute (x): ability to execute file as a program.
    • Permissions can be set using:
      • chmod command: sets permissions for a file or directory.
      • chown command: sets ownership of a file or directory.
    • Permission levels:
      • User (owner): has full control over file or directory.
      • Group: has shared access to file or directory.
      • Others: has limited access to file or directory.

    Partitioning

    • Partitioning involves dividing a hard drive into separate sections for storing data.
    • Key concepts:
      • Primary partition: main partition on a hard drive, used for booting.
      • Extended partition: secondary partition, used for storing data.
      • Logical partition: subdivision of an extended partition.
    • Partitioning tools:
      • fdisk: command-line partitioning tool.
      • gparted: graphical partitioning tool.
    • Partitioning schemes:
      • MBR (Master Boot Record): legacy partitioning scheme.
      • GPT (GUID Partition Table): modern partitioning scheme.

    Samba Server

    • Samba is a free, open-source implementation of the SMB/CIFS protocol, allowing Linux systems to share files and printers with Windows systems.
    • Key features:
      • File and printer sharing: allows Windows systems to access Linux files and printers.
      • User authentication: integrates with Linux user authentication systems.
      • Configuration: can be configured using the smb.conf file.
    • Common Samba commands:
      • smbclient: command-line tool for accessing Samba shares.
      • smbstatus: displays information about Samba shares and connections.
      • testparm: tests Samba configuration file for errors.
