Sharing files over the network is often very useful. Whether you need to transfer media files to the Raspberry Pi or you want to use the raspberry as a simple Network-Attached Storage (NAS) device, this guide will show you how to enable file sharing of a folder on the Raspberry Pi running the Raspbian OS.

 

Prerequisites & Equipment

You are going to need the following:

• A Raspberry Pi ()
• A SD Card flashed with the Raspbian OS (Here is a  if you need)
• Access to the Raspberry either via keyboard and a monitor or 
• A home network
• A Windows computer (for this guide we will be running Windows 7)

Install and configure required software

To share network folders to a Windows computer we need to install some special software on the Raspberry Pi. The software providing the secret sauce this time is called Samba. The Samba software package implements the SMB protocol and provides support for the Windows naming service (WINS) and for joining a Windows Workgroup.

Installing the software is easy – login to your Raspberry Pi and run:

sudo apt-get install samba samba-common-bin

After installation configure the software by opening the file /etc/samba/smb.conf using the command:

sudo nano /etc/samba/smb.conf

Read through the file and make sure you have the following parameters set:

workgroup = WORKGROUPwins support = yes

You can use anything as your workgroup name as long as it is alphanumerical and matches the workgroup you would like to join. The default workgroup in Windows 7 is WORKGROUP.

Setup folder to share

Next step is to create the folder you would like to share. To create a folder called “share” in your home directory do the following:

mkdir ~/share

With the folder created we can now tell the Samba software to share it on the network. Open the file /etc/samba/smb.conf using the command:

sudo nano /etc/samba/smb.conf

Scroll to the bottom and add the following:

[PiShare] comment=Raspberry Pi Share path=/home/pi/share browseable=Yes writeable=Yes only guest=no create mask=0777 directory mask=0777 public=no

Notice how we tell Samba that public access is not allowed via “public=no” – this means that anyone wanting to access the shared folder must login with a valid user.

In this case the valid user is the user called “pi”. To let Samba know that “pi” is a network user run the command:

sudo smbpasswd -a pi

And enter pi’s password twice (default: raspberry).

At this point we can now login to the share from our Windows computer – use Domain: raspberrypi, User: pi and Password: raspberry (unless you changed the password) as you can see below:

If you do not want to deal with logging in you can always make the share publicly available by changing the config file to say:

public=yes

However please note that this is extremely dangerous since anyone will be able to access, modify and delete your files.
