Session 2: Managing Common Storage for Students & Security Configuration

Intranet-Based File Storage:

Overview:

• How to set up shared folders on the local network (Intranet), accessible by all students with unique logins.
• Linux: Configure Samba for file sharing on the intranet.

Why Use Intranet-Based File Storage?

• Provides a secure and controlled environment for students to access and share files.
• Eliminates dependency on external cloud storage, reducing security risks.
• Enhances collaboration and ensures easy monitoring of access and file changes.

Basic Samba Configuration:

1. Install Samba:

   sudo apt update
   sudo apt install samba
2. Create a shared directory:

   sudo mkdir -p /srv/samba/shared
   sudo chmod 777 /srv/samba/shared
3. Edit Samba configuration file:

   sudo nano /etc/samba/smb.conf
   Add the following lines at the end:

   [SharedFolder]
   path = /srv/samba/shared
   browseable = yes
   writable = yes
   guest ok = no
   valid users = @students
4. Create a Samba user group:

   sudo groupadd students
5. Add students to the group and set Samba password:

   sudo usermod -aG students student1
   sudo smbpasswd -a student1
   If you get an error like usermod: user 'student1' does not exist, create the user first:

   sudo useradd -m student1
   sudo passwd student1
   Then re-run the usermod and smbpasswd commands.
6. Restart Samba service:

   sudo systemctl restart smbd

Testing Samba Configuration:

1. Verify Samba Service:

   sudo systemctl status smbd
2. Check Shared Folder Permissions:

   ls -ld /srv/samba/shared
3. Test Access from Another System:
   • On Windows, open File Explorer and enter \\<server-ip>\SharedFolder in the address bar.
   • On Linux, use the smbclient command:

     smbclient -U student1 -L //<server-ip>/SharedFolder

By following these steps, administrators can ensure smooth and secure user and storage management for students.
