Stepwise Guide to Setting Up SMB File Sharing for Windows, Mac and Linux


Below are included instructions for setting up a shared folder and for connecting your DeNovix instrument to the shared folder through the network. 

The sections below contain steps for different types of setups. Please refer to the appropriate section applicable to your IT situation. 

  1. Configure a Windows PC for SMB Data Transfer
  2. Configure a Mac for SMB Data Transfer
  3. Configure a Linux PC for SMB Data Transfer
  4. Set up SMB Data Transfer on your DeNovix instrument
    1. Android OS
    2. Linux OS

A. Configuring a Windows PC for SMB Data Transfer

1. Turn on SMB Sharing

In the Search bar, look for “Turn Windows features on or off.” Find SMB 1.0 File sharing support and SMB Direct. If your DeNovix instrument has an Android OS, check the SMB 1.0 boxes and the SMB Direct box. If your instrument has a Linux OS, it is not necessary to turn on SMB 1.0. In this case, only check the SMB Direct box. 

While configuring the Windows PC, you may need to reboot the instrument to enable certain settings.

2. Set up Network Sharing

From the Start menu, open Settings and select Network & Internet

3. Choose Properties

Set Network profile to Private. Click “Configure firewall and security settings.” Ensure Private network firewall is turned off.

4. Click “Private Network”

Make sure the “Blocks all incoming connections” checkbox is NOT checked.

5. Ensure that Private Network Firewall is Turned Off
6. Click “Private Network”

Make sure the “Blocks all incoming connections” checkbox is NOT checked.

7. Return to Settings

Choose “Network and Sharing Center”

8. Click “Change Advanced Settings”
9. Under “Private”

Check to be sure network discover and file and printer sharing are on.

10. Create a New Folder

This example is on the desktop and the folder is called “dave-share.” Right click on the folder, choose “Give access to” then click “Specific people.”

11. Select “Everyone” and Choose “Read / Write.” Then Click Share.
12. The Windows Network Folder is Now Available.

Note the share name. In this example the share name is dave-share. This will be used for the Path in the Network folder settings.

13. Required Network Information

Make sure the instrument is connected to the same network as the Windows PC. Connections can be by WiFi or ethernet.

  • Identify the IP address of the Windows PC. This is found in Network status under “Properties”. Another option is to use the command prompt and enter   ipconfig  
    • The wireless IP address is reported in the “Wireless LAN adapter Wi-Fi” section.
  • Identify the domain name the Windows computer is using.
    • From the command prompt, type     echo %userdomain%
  • Identify the user name the Windows PC is using.
    • From the command prompt, type    echo %username%
  • Identify the share name the shared folder (user-share in example below). This is used for the “path” field. The share name (path) should always be in only lower case.
    • Right click on shared folder and view properties to see the share name and that the network path is proper for an SMB share.

B. Configuring a Mac for SMB data transfer

Note: SMB data transfer for Mac is only compatible with Linux OS DeNovix instruments (see below).

  1. Create a folder in a location of your choice
  2. Open System Preferences on your Apple computer and select Sharing
  3. Add the folder you created by clicking the plus button underneath the “Shared Folders” field. 
  4. Select that folder and then click “Options…” Here you will be able to select the users that have access to this folder by checking the box next to their name. Each user selected will require their password to be entered to allow access.

Note: If you are trying to add the same username as the MacBook/iMac that you are using but you are not sure of the username, open the Terminal (Finder > Applications > Terminal) and type whoami into the window and press enter. This will show you the username of your device.

  1. The Sharing screen (see image) provides the information required to set up SMB-sharing on a DeNovix instrument
    • Computer Name at the top of the screen should be added to the “Domain” field on the network folder set-up on your DeNovix device. Note: Do NOT add the .local.
    • Directly underneath “File Sharing: On” you will find the computer’s local IP address preceded by smb:// This should be entered in the “Server” field of the network folder set-up on your DeNovix device. Note: Do NOT use the smb:// in front of the IP address.

 C. Configuring a Linux PC for SMB data transfer

  1. Ensure that your Linux PC has the appropriate Samba packages installed and is connected to a network before proceeding with the rest of this walkthrough. 
  2. The “Server” field on the network folder set-up needs your device’s local IP address. To find this, type ifconfig in the Terminal and use the IP address under the heading BROADCAST. Note: Generally local IP addresses will start with 192.168… so look for that address in the resulting information.
  3. The “Domain” field needs the device’s hostname. This can be found by entering the command hostname into the Terminal. Enter the resulting hostname into the Domain field on the DeNovix device. 
  4. The “Path” field needs the Share Name from the device. This can be found by navigating to /etc/samba/smb.conf Open the smb.conf file and scroll down to the bottom of the document where you will find path=…… where the exact path to your folder will be located. Right above that in brackets […] you will find the Share Name. 
  5. Enter the username and passwords in their respective fields and press connect. 
  6. After seeing a “Pass” result, select “Send Test File” to ensure that the devices are able to communicate with one another.

D. Setting up your DeNovix Instrument

Determine the Operating System of your DeNovix Instrument

Follow the instructions in the appropriate section below. 

  1. Linux OS: All CellDrop instruments and DS-11 / QFX / DS-C shipped since March 2021

  3. In the “Server Hostname” field, enter the IP address of the host PC
  4. In the “Username”, enter the Username.
  5. Enter the password used to log in to the PC
  6. The Path will be filled in automatically by following these steps
    • Click the “Browse” button
    • Locate the shared folder (“dave-share” in this example) and click it

    • Click ok to select the folder
  1. Click OK to save the network folder settings

 If the connection reports “fail”, carefully review the Windows network, sharing and firewall settings.

  1. Test Exporting
