Sharing files and folders between Windows and Linux systems on peer-to-peer (p2p) networks.

Overview

The purpose of this exercise is to introduce how computer systems can share information (files and folders) by one system sharing a folder and letting onther systems access that folder within a subnet.

Learning Objectives

In this exercise, you wil learn how to share folders on Windows and Linux systems with other Windows and Linux systems.

NOTE: Your "PersonalVolume" should be mounted on the LINUX Desktop for the following to work. If it is not, then open up the file manager and mount it (or Double-Click it). Verify that the "PersonalVolume folder is located on the computer (root drive) at /media/admin/.

If your "PersonalVolume is mounted on the Desktop, but not contained within "/media/admin", then it might be mounted in "/mnt/. You can verify this by executing "ls /mnt" within a terminal window. If this is the case, “un”mount the PersonalVolume as follows:

sudo umount -f "/media/admin/PersonalVolume

Then mount it again by going to PersonalVolume using the File Manager and double clicking on “PersonalVolume”.

1. Change permissions on secondary storage

sudo chmod -R 777 "/media/admin/PersonalVolume

2. Create folder on secondary storage

mkdir "/media/admin/PersonalVolume/share"

3. Install SAMBA

sudo apt-get update
sudo apt-get install samba

4. Edit the SAMBA smb.conf file

cd /etc/samba/
sudo rm smb.conf
sudo touch smb.conf
sudo nano smb.conf

Add the following text into the smb.conf file

[share]
path = "/media/admin/PersonalVolume/share"
browseable = yes
read only = no
guest ok = yes

Then press ctrl+x then type “y” then hit enter.

5. add smbuser by the command

sudo smbpasswd -a admin

(username must be the user on the LINUX os - i.e. admin)

6. start the smbd and nmbd services

sudo service smbd start
sudo service nmbd start

1. From within Windows File Explorer, enter the location \\10.0.10.21

2. Right-button click on the shared folder and select “Map network drive…”

3. Choose a drive letter and click on “Finish”

1. Create folder on secondary storage using the Commamd prompt.

d:
cd /
md share

2. Set properties of the shared folder to be shared

  • Right-button click on folder within file explorer
  • Select “properties”
  • Choose the “Sharing” tab on the “Properties” dialog box.
  • Click on the "Share…" button
  • Click on the down arrow to Select “Everyone”
  • Click the Add button
  • Change the permission Level to Read/Write to share
  • Click on the "Share" button
  • Then click on “Done” and click on “Close”

NOTE: Your "PersonalVolume should be mounted on the LINUX Desktop for the following to work. If it is not, then open up the file manager and mount it (or Double-Click it). Verify that the "PersonalVolume folder is located on the computer (root drive) at /media/admin/.

If your "PersonalVolume is mounted on the Desktop, but not contained within "/media/admin", then it might be mounted in "/mnt/. You can verify this by executing "ls /mnt" within a terminal window. If this is the case, “un”mount the PersonalVolume as follows:

sudo umount -f "/media/admin/PersonalVolume

Then mount it again by going to PersonalVolume using the File Manager and double clicking on “PersonalVolume”.

1. Install CIFS

sudo apt-get update
sudo apt-get install cifs-utils

2. Create a directory "share" in the PersonalVolume

3. Mount the WINDOWS shared folder

sudo mount.cifs //10.0.10.11/share “/media/admin/PersonalVolume/share” -o user=admin rw file_mode=777 dir_mode=777

4. Create by editing a new file (i.e. filename) using nano

sudo nano “/media/admin/PersonalVolume/share/filename"

5. Check it out on the Windows VM

6. Now delete your share

sudo umount -f “/media/admin/PersonalVolume/share/filename”
