How to Set Up Samba Private Network File Share on Ubuntu VPS (Windows & Mac Remote Drive)

The Convenience of Remote Network File Sharing

Managing files through web interfaces or terminal SFTP clients is fine for occasional tasks, but for video editors, graphic designers, and office teams handling large raw assets, mounting remote storage directly as a native letter drive (e.g. Z: in Windows) provides seamless drag-and-drop productivity. Samba implements the standard SMB networking protocol on Linux servers.

Important ISP Security Requirement: WireGuard Tunneling

Most consumer Internet Service Providers (ISPs) block TCP port 445 to prevent WannaCry-style SMB malware propagation across the public Internet. Therefore, Samba should always be routed through your private WireGuard VPN tunnel (10.8.0.1) connecting your computer securely to your Contabo VPS.

Step 1: Installing and Configuring Samba on Ubuntu

sudo apt update && sudo apt install -y samba

# Create storage directory and assign ownership
sudo mkdir -p /srv/shares/storage
sudo chown -R $USER:$USER /srv/shares/storage

Configure the share in /etc/samba/smb.conf:

sudo nano /etc/samba/smb.conf

[CloudStorage]
   comment = Private Cloud Network Drive
   path = /srv/shares/storage
   read only = no
   browsable = yes
   valid users = @smbgroup
   create mask = 0660
   directory mask = 0770
   smb encrypt = mandatory

Step 2: Adding Samba User and Setting Passwords

sudo smbpasswd -a $USER
sudo systemctl restart smbd

On Windows Explorer, click Map Network Drive, enter \\10.8.0.1\CloudStorage, enter your Samba credentials, and enjoy instant access to your remote storage volume.
