[LINUX] File sharing server made with Raspberry Pi that can be used for remote work

Introduction

This article describes how to build a file sharing server at home using Raspberry Pi.

Suppose your company distributes a Windows PC for remote work. Taking the designer as an example, if you want to copy the data on Windows distributed by your company to your Mac at home and work on it, you need some way to share files.

You can share files with online storage services such as Dropbox, but a convenient file sharing server is one that you can use at home.

By installing ** Samba ** on Raspberry Pi and building a file sharing server, you can easily share files on Windows and Mac.

SMB ** SMB (Server Message Block) ** is a protocol for sharing files and printers between Windows computers.

Use ** NetBIOS ** as the underlying protocol. There is also a protocol called ** CIFS ** that extends SMB. CIFS uses TCP / IP directly.

Building Samba

--Installing Samba $ sudo apt-get install samba samba-common-bin --Create a shared folder $ sudo mkdir /var/samba
--Creating a user to access a shared folder $ sudo useradd smbuser

• password setting $ sudo passwd smbuser --Permission change $ sudo chown smbuser:smbuser /var/samba/ --Samba access settings $ sudo pdbedit -a smbuser --Public settings for shared folders $ sudo cp -p /etc/samba/smb.conf /etc/samba/smb.conf.org
$ sudo vi /etc/samba/smb.conf

Add the following to the /etc/samba/smb.conf file.

[share]
   comment = Share Folder
   browseable = yes
   path = /var/samba
   writable = yes
   valid users = smbuser
   force user = smbuser

--Restarting Samba $ sudo /etc/init.d/samba restart

pdbedit The pdbedit command manages the SAM database (the database for Samba users). It is used to manage the user accounts held in the SAM database and can only be run by root.

You can use pdbedit to add user accounts, delete user accounts, change user accounts, list user accounts, and import user accounts.

--List database user accounts $ sudo pdbedit -L

smbuser:1001:

--List database user accounts (details) $ sudo pdbedit -L -v

File sharing server access

If the firewall is enabled on the Raspberry Pi side, it is assumed that the communication used by Samba is permitted, and the access methods for Windows and Mac are described.

Windows To access Samba on Windows 10, you need an SMB client. For Windows 10, SMB 1.0 is disabled, so follow the steps below to enable the SMB client.

1. Open the control panel
2. From the program, open [Turn Windows features on or off]
3. Check [SMB 1.0 / CIFS Client] and click [OK].
4. After activating the SMB client, access \\ <Raspberry Pi IP address>: \ share \ on the network from Explorer.
5. You can access the file sharing server by entering the smbuser credentials you created earlier.

Mac For Mac, access from Finder.

1. Select [Connect to Server] from [Go] in Finder.
2. Enter smb: // <Raspberry Pi IP address> in [Server Address] and click [Connect].
3. Select the registered user and enter the smbuser authentication information created earlier to access the file sharing server.

in conclusion

Make effective use of Raspberry Pi and use it for remote work.
