I would start this post with “What is a Samba share?”.
So to save me some trouble explaining here is a snippet from Wikipedia about the SMB protocol:
In computer networking, Server Message Block (SMB), one version of which was also known as Common Internet File System (CIFS/sɪfs/), is a network communication protocol for providing shared access to files, printers, and serial ports between nodes on a network.
With that aside, I have this small server in my homelab that I frequently use it as a test bench for different kinds of Linux projects. It currently runs on Ubuntu Server 19.10.
It’s an AtomicPi, a small single-board computer. Much like its slower but more broadly known Raspberry Pi brother. This one features SoC Intel Chip – Intel Atom x5-Z8350, 2GB RAM and 16GB internal storage.
You can find more info here if you are interested: https://dlidirect.com/products/atomic-pi
It’s a cool thing, you can even run Windows on it. Install Linux and Docker, and you can run different kinds of containers with your favorite apps. I use it with Nextcloud and as a DNS AdBlock with Pi-hole. And as of recently as a small NAS storage device. The possibilities are endless.
In the image above you can see the external SSD drive in USB enclosure connected to its one-and-only USB port. Hey, at least it’s 3.0.
The external drive, I use it frequently to transfer files from one device to another and since they are mainly Windows it’s formatted as NTFS. I didn’t want to format it as a Linux partition with Ext4 FS or similar and wanted to stay as it is. When I don’t use it it will be on the server for network file sharing, and when I use it will be ready with NTFS for Windows.
As you may know, Linux isn’t much fond of the NTFS file system so before beginning with all of this, you will need to download the proper driver on your server(if it doesn’t have it already).
I will presume that you run Ubuntu or Debian since this tutorial will be targeted towards those.
While at your terminal download this NTFS driver:
Run the following command:
$ sudo apt-get install ntfs-3g
If you type the driver only as ntfs-3g in the terminal you should get the following output:
[email protected]:~$ ntfs-3g ntfs-3g: No device is specified. ntfs-3g 2017.3.23AR.3 integrated FUSE 28 - Third Generation NTFS Driver Configuration type 7, XATTRS are on, POSIX ACLS are on Copyright (C) 2005-2007 Yura Pakhuchiy Copyright (C) 2006-2009 Szabolcs Szakacsits Copyright (C) 2007-2017 Jean-Pierre Andre Copyright (C) 2009 Erik Larsson Usage: ntfs-3g [-o option[,…]] Options: ro (read-only mount), windows_names, uid=, gid=, umask=, fmask=, dmask=, streams_interface=. Please see the details in the manual (type: man ntfs-3g). Example: ntfs-3g /dev/sda1 /mnt/windows News, support and information: http://tuxera.com [email protected]:~$
That means that the driver has been successfully installed.
Plug in your external HDD or SSD if it isn’t plugged in already and find out its device name and partition.
Run the following command to find out which “name” has your disk.
$ sudo fdisk -l
As you can see in my case the disk is listed as /dev/sdb with its partition as /dev/sdb1.
[email protected]:~$ sudo fdisk -l Disk /dev/loop4: 93.8 MiB, 98336768 bytes, 192064 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mmcblk0: 14.58 GiB, 15636365312 bytes, 30539776 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: C7395571-3969-4CAC-A3DF-53A7DB5B05D1 Device Start End Sectors Size Type /dev/mmcblk0p1 2048 1050623 1048576 512M EFI System /dev/mmcblk0p2 1050624 30537727 29487104 14.1G Linux filesystem Disk /dev/sdb: 55.92 GiB, 60022480896 bytes, 117231408 sectors Disk model: 35T060G Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 4096 bytes / 33553920 bytes Disklabel type: dos Disk identifier: 0x00049a68 Device Boot Start End Sectors Size Id Type /dev/sdb1 2048 117229567 117227520 55.9G 7 HPFS/NTFS/exFAT [email protected]:~$
If your disk isn’t partitioned it won’t display the device part i.e the sdb1, and you’ll need to format it but for reasons stated above this was already done by Windows.
In Linux servers, you will also need to mount the disk to a folder in order to access its contents. Which we will proceed to do with the next few commands.
Since the device name or notation can change with different USB devices plugged in or out, we will need to find out the disk UUID since that is a unique value and won’t change. Type the following command to retrieve it.
$ sudo blkid
Here is my output, and since we already know that the partition is at /dev/sdb1, we can see the UUID. Copy it because we will need it for the configuration in fstab.
[email protected]:~$ sudo blkid /dev/mmcblk0p1: UUID="9784-16D6" TYPE="vfat" PARTUUID="a1cf2c59-7f69-47bc-8ff7-b1c8711749f2" /dev/mmcblk0p2: UUID="5d14cea7-1341-49ac-aa12-8efe8336ae89" TYPE="ext4" PARTUUID="20a8f102-8b88-4b71-b69e-02c63432cf14" /dev/sdb1: UUID="19C8C6CB711BD991" TYPE="ntfs" PTTYPE="dos" PARTUUID="00049a68-01" /dev/loop4: TYPE="squashfs" [email protected]:~$
Now to need to make the OS automount the disk’s partition so we don’t manually mount it every time we restart the server. We will need to insert a small config in the fstab configuration.
But first, create a folder where would you like to have all contents mounted from the disk’s partition. I will make it in /home/ubuntu/ named as MSSD.
Run mkdir to make a directory, and the next argument will be your directory name.
$ mkdir MSSD
[email protected]:~$ mkdir MSSD [email protected]buntu-server:~$ ls -l total 8 -rw-r--r-- 1 root root 1320 Dec 5 2002 jcameron-key.asc drwxrwxr-x 2 ubuntu ubuntu 4096 Apr 14 17:21 MSSD [email protected]:~$
The command ls -l is used to list all the contents of that directory. We can see that (mine at least) MSSD folder has been created successfully.
The fstab is a configuration file that keeps track of the mounted disk and file partitions. Read more here https://en.wikipedia.org/wiki/Fstab
The fstab is located at /etc/fstab, let’s edit it to insert our new disk and mount it to our folder.
$ sudo nano /etc/fstab
UUID=5d14cea7-1341-49ac-aa12-8efe8336ae89 / ext4 defaults 0 0 UUID=9784-16D6 /boot/efi vfat defaults 0 0 /swap.img none swap sw 0 0
You can already see that there are previous entries and we will need to insert our below them. Be careful as to not delete or edit the previous ones since you can damage your server.
In my case, the config command will go like this. Focus on the bolded lines.
UUID=5d14cea7-1341-49ac-aa12-8efe8336ae89 / ext4 defaults 0 0 UUID=9784-16D6 /boot/efi vfat defaults 0 0 /swap.img none swap sw 0 0 UUID="19C8C6CB711BD991" /home/ubuntu/MSSD ntfs-3g permissions,locale=en_US.utf8 0 2
The first part is the device or our UUID which we retrieved previously. The second is the mount point, the folder that we created(MSSD), and the third is the NTFS driver to interface it. The permissions are well… for changing the permissions if we need to. The locale is to set the encoding of the disk as UTF8.
Now for the last two fields. The first is set to 0 to ignore dumping/backing in Linux and the second, written 2 is set for file system checking(fsck) on boot. 0 is set for skipping fsck, 1 is used only if the mounted partition is the root partition and 2 for all others. So in our case, it’s 2.
Save the configuration, and remount the drives.
$ sudo mount -a
Now, let’s check again our disk if it’s mounted:
[email protected]:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 910M 0 910M 0% /dev tmpfs 191M 7.9M 183M 5% /run /dev/mmcblk0p2 14G 6.7G 6.5G 51% / tmpfs 951M 0 951M 0% /sys/fs/cgroup /dev/loop4 94M 94M 0 100% /snap/core/8935 tmpfs 191M 0 191M 0% /run/user/1000 /dev/mmcblk0p1 511M 7.8M 504M 2% /boot/efi /dev/sdb1 56G 6.3G 50G 12% /home/ubuntu/MSSD [email protected]:~$
And there is our disk, mounted and working. Another check with ls -l to see if we can view the contents.
[email protected]:~$ cd MSSD/ [email protected]:~/MSSD$ ls -l total 13940 drwxrwxrwx 1 root root 0 Apr 14 13:11 '$RECYCLE.BIN' drwxrwxrwx 1 root root 8192 Apr 14 12:32 Books drwxrwxrwx 1 root root 0 Apr 14 13:12 KT ---------- 2 root root 14262842 Apr 14 00:19 Mega drwx------ 1 root root 0 Apr 14 13:10 'System Volume Information' [email protected]:~/MSSD$
On to the second part, installing the Samba server.
$ sudo apt-get install samba
First, create an account for the Samba access in order to have some kind of authentication. I will create the user as ubuntu.
$ sudo smbpasswd -a ubuntu
[email protected]:~$ sudo smbpasswd -a ubuntu New SMB password: Retype new SMB password: [email protected]:~$
Now open the config file located at /etc/samba/smb.conf in order to make our folder shareable on the network.
$ sudo nano /etc/samba/smb.conf
At the bottom of the wall-of-text file, insert the configuration like below. Feel free to edit the name, but make sure you know what you are doing about the other options.
[Linux - MSSD] path = /home/ubuntu/MSSD available = yes valid users = ubuntu read only = no browseable = yes public = yes writable = yes
The path is our folder created previously, the user is the one we created two commands before. Make sure those are correct and restart the samba service.
sudo service smbd restart
Now switch back to your Windows, and navigate to your server.
You will be prompted for login info, insert the account you created for the Samba access.
That’s it. You’ve successfully created a samba share!
In case you have some issues with permissions try to change the folder ownership with chmod. For example:
$ sudo chown -R ubuntu:ubuntu MSSD/
