Introduction​

This cheat sheet provides a quick reference for some common CIFS (Common Internet File System) commands and concepts. CIFS is a network file-sharing protocol that allows the sharing of files and resources between computers over a network, often used in Windows-based environments.

CIFS Concepts​

Shares​

A CIFS share is a network resource (folder or directory) that is shared with other computers.

  • Create a CIFS share in the smb.conf configuration file:
    [share_name]
      path = /path/to/shared_folder
      read only = no
      guest ok = yes

Authentication​

CIFS supports authentication for accessing shared resources.

  • Access a CIFS share with a username and password:
    smbclient //server/share -U username

Mounting CIFS Shares​

You can mount CIFS shares on your local system.

  • Mount a CIFS share using mount:
    sudo mount -t cifs //server/share /mnt/mount_point -o username=user,password=pass

Permissions​

CIFS shares can have access permissions similar to file system permissions.

  • Set CIFS share permissions in the smb.conf file:
    [share_name]
      path = /path/to/shared_folder
      valid users = user1, user2
      read only = no

Configuration File​

The main configuration file for CIFS is typically /etc/samba/smb.conf.

Status and Debugging​

You can check the status of CIFS and debug issues using logs.

  • Check the status of the smbd service:

    systemctl status smbd

  • View CIFS logs (e.g., smbd logs):

    tail -f /var/log/samba/log.smbd

CIFS Command-Line​

  • Start the CIFS service (SMB server):

    sudo systemctl start smbd

  • Stop the CIFS service:

    sudo systemctl stop smbd

  • Restart the CIFS service:

    sudo systemctl restart smbd

  • Reload CIFS configuration:

    sudo systemctl reload smbd

Conclusion​

This cheat sheet covers some common CIFS (Common Internet File System) commands and concepts. CIFS is a network file-sharing protocol used for sharing files and resources between computers; refer to the official Samba documentation for more in-depth information and advanced usage.
