Creating a NAS with Ubuntu Server

This setup guide will show you how to setup a Network Attached Storage (NAS) system
with Ubuntu Server, create Samba / SMB shares, install Usenet file downloader, and install
automated Usenet downloaders SickBeard and CouchPotato.

Use this guide along with my Youtube Video: http://youtu.be/-5Z_-3EBIHE

Terminal commands are written in Orange

Settings you need to change for your system are written in Purple

Items Required:
● Wired Network Connection
● Small USB Flash drive (or CD) to install the OS
● 8GB (Minimum) Flash drive to run the OS
● A few spare hours

A NAS device can be created with minimal hardware, such as: Single core 1.0GHz CPU, 512
MB RAM, 160GB Hard Drive, and a USB 2.0 Flash drive.

For my NAS Im using: AMD E-450 CPU (1.6GHz dual core), 8GB DDR3 RAM, 3x 3TB
Seagate hard drives, and a 16GB USB3.0 Flash drive.
The system is running with RAID5 giving me a single 6TB drive mounted in /media. It
has SMB shares setup, which allows shared access for all devices (computers, media
player, and Android tablet) on my LAN.
I’m also using the system as a Media Downloader to download files from Usenet.

Majority of user interaction is done via Web GUI’s, although there’s remote access terminal
available via SSH. Since everything can be done remotely over the network the NAS sits
there running as a headless server (no keyboard or monitor connected).
 Installing Ubuntu Server

Download Ubuntu Server from: http://www.ubuntu.com/download/server

Either write it to the small USB Flash drive or CD

We are going to install the operating system to a USB Flash drive, this makes it easier to
use the hard drives in a RAID array and keep the OS separate from data storage. Ubuntu
Server is light enough to run on a Flash drive, and with enough RAM theres no appreciable
delay in using the NAS.
It's certainly a cheaper alternative than installing the OS on a Solid State Disk.

Disconnect all hard drives and then install the Server OS onto the Flash drive.

Near the end of the install it asks you which components you would like to install, from
that list choose SSH Server, and Samba.
Shutdown the computer, reconnect all hard drives, and then switch back on.

If all being well you will get a login screen. Login with your username and Password.

Firstly Check For Updates

sudo aptget update
sudo aptget distupgrade
sudo reboot

Set Static IP Address

sudo nano /etc/network/interfaces
iface eth0 inet static
address 192.168.1.100
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1
dnsnameservers 192.168.1.1 8.8.8.8

Adjust the IP addresses for your network.

8.8.8.8 is Google DNS Server, I find this a lot better than my ISP’s DNS Server.
Add NAS IP Address to your Local DNS Lookup
This is on any Linux computer that you would like to access the NAS from.
sudo echo "192.168.1.100 nas.local" >> /etc/hosts

The NAS can be accessed via SSH with the following terminal command:
ssh user@nas.local

Install MDADM RAID Controller (Optional if using RAID)

sudo aptget noinstallrecommends install mdadm

Install Webmin
http://www.webmin.com/download.html
sudo aptget install libaptpkgperl libnetssleayperl libauthenpamperl
libioptyperl aptshowversions
cd ~
wget http://prdownloads.sourceforge.net/webadmin/webmin_1.580_all.deb
sudo dpkg i webmin*.deb
sudo reboot

Setup RAID
Open browser and navigate to: https://nas.local:10000
Create and mount RAID via Webmin RAID setup utility.
Setup a mount point for the RAID in /media/raidmount
(It took approximately 36 hours to create a 9TB RAID5 array on my system, but the
system was fully usable for this time)

Alternatively Mount a Single Drive instead of RAID

sudo mkdir /media/disk1
sudo blkid
Take a note of the ID number for the drive you would like to mount
sudo nano /etc/fstab
Add new line:
UUID=“ID From blkid” /media/disk1 ext4 rw,user,auto 0 0

Note: for the remainder of the document I refer to the mounted drive as “raidmount”, but this
doesn’t mean it has to be a RAID

Create Shared Folders

sudo su
cd /media/raidmount
mkdir Folder1
mkdir Folder2

Depending how you would like Samba / SMB shares to be accessed you have two choices:
1. Read/Write Access for one user, and Read Only Access for everyone else
2. Read/Write Access for everyone

Read/Write Access for one user:

chown user:user Folder1/
chown user:user Folder2/

Read/Write Access for everyone:

chmod a=rw R /media/raidmount
chown nobody:nogroup Folder1/
chown nobody:nogroup Folder2/

Setup Samba Shares

Backup old Config File:
sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.old

Example smb.conf file can be found at Annex A (at the end of this document)
Use Webmin > Servers > Samba Windows File Sharing > Edit Config File, to copy and paste
example Config file in.

Click “Restart Samba Servers” button after editing Config file

 Usenet Components
