Cubietruck. Travel mini server. Part 1
The idea of such a server was born on vacation. In the evening I wanted to watch an online TV show on a tablet, but due to an unstable 3G reception, viewing turned into flour. Alternatively, you could download a series, but again, when downloading, the signal constantly floated, the speed jumped and the tablet had to be kept constantly on and on charge (application specifics). By evening, a couple of episodes were downloaded and you could safely watch the series.
At this time, the idea of creating this device was born. On the Internet, a large number of information storage implementations on single-board computers of different manufacturers, but a combination of several solutions was not found.
What is in the plans: The
brain of the entire Cubietruck
HDD system is a 500Gb
USB modem HUAWEI E3372
Power AC-DC 5V
Power DC-DC 12V - 5V (for the car)
How it will work:
At home it will be an ordinary NAS connected via a network cable (lan) and attached to the computer as a simple network drive.
A WI-FI access point will constantly work on CubieTruck (in case there is no Wi-FI, but there is only a cable with DHCP).
In the case when a network cable (lan) is connected in Cubietruck, the device connected to the Cubietruck access point must go to the Internet via a network cable, and not 3G. The modem should start working when a network cable is not connected to Cubietruck.
When tuning relied on the post Cubietruck. A cozy, home server, so I will not describe the installation process of the system.
Network settings
I did all the settings on Windows.
We write the system image to the USB flash drive, put it in its place and turn on Cubietruck.
The system itself is installed and rebooted. After that, Cubietruck with Cubian installed is ready to go.
In the absence of an HDMI monitor and keyboard, we need Putty .
We go to the device with DHCP (router and server) we find the ip of our Cubietruck. We
connect using port 36000 , since this is the default port in SSH Cubian.
Username / password cubie / cubie
During the configuration process did not change.
I personally changed the port.
To do this, edit sshd_config
sudo nano /etc/ssh/sshd_config
Find the line with port 36000
Port 36000
Change to
Port 22
Save. The editor nano for storing click Ctrl + O then Enter and Exit Ctrl + X .
Reboot
sudo reboot
Now we can all connect via standard port 22
Since the cube is planned as something portable, in the future the eth0 interface, that is, the Enternet port will work via DHCP , but now for convenience, I will assign it a static address:
The interface settings are stored in the / etc / network / file interfaces
sudo nano /etc/network/interfaces
Default configuration
auto lo
iface lo inet loopback
#
auto eth0
iface eth0 inet dhcp
We change the eth0 interface . Do not forget that everyone changes the settings for themselves
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.168.1.247
netmask 255.255.255.0
gateway 192.168.1.10
dns-nameserver 192.168.1.7
Reboot
sudo reboot
We ping the ya.ru host and check its availability.
cubie@Cubian:~$ ping ya.ru
PING ya.ru (213.180.193.3) 56(84) bytes of data.
64 bytes from www.yandex.ru (213.180.193.3): icmp_req=1 ttl=56 time=2.04 ms
64 bytes from www.yandex.ru (213.180.193.3): icmp_req=2 ttl=56 time=1.82 ms
64 bytes from www.yandex.ru (213.180.193.3): icmp_req=3 ttl=58 time=1.95 ms
The answer is, the network is configured
HDD auto-mount
Create a folder where the HDD will be mounted.
sudo mkdir /media/files
We give read / write access rights to all users.
sudo chmod 777 /media/files
Browse HDD sections.
sudo fdisk -l
I have a 500Gb drive installed
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 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 identifier: 0x82e3ff7e
Format the disk to the ext4 file system
sudo mkfs.ext4 /dev/sda
Find out the UUID of our HDD
sudo blkid
/dev/mmcblk0p1: LABEL="cubieboard" UUID="2a1124a9-6108-4da0-932f-78ccbfd92458" TYPE="ext4"
/dev/sda: UUID="ff0caf96-39b9-4aff-a4d0-5892abfdca8f" TYPE="ext4"
We need UUID / dev / sda
Copy UUID without quotes
ATTENTION. Each drive has its own UUID.
Now we add an entry to / etc / fstab
sudo nano /etc/fstab
At the very end, add
UUID=ff0caf96-39b9-4aff-a4d0-5892abfdca8f /media/files ext4 defaults,acl,user,user_xattr,errors=remount-ro
* Attributes are set to your liking.
Records are separated by either a space or a tab.
Reboot:
sudo reboot
After rebooting, check
mount
The disk is mounted in the system
/dev/sda on /media/files type ext4 (rw,nosuid,nodev,noexec,relatime,errors=remount-ro,data=ordered)
If the disk is formatted in NTFS and needs to be mounted on the system
Device Boot Start End Blocks Id System
/dev/sda1 2048 234438655 117218304 7 HPFS/NTFS/exFAT
First, update the list of repositories and search for indexes of updated versions of programs, drivers, the kernel and everything else:
sudo apt-get update
In order to install the ntfs-3g utility
sudo apt-get install ntfs-3g
Find out the UUID of our section
sudo blkid
/dev/sda1: LABEL="M-PM-^]M-PM->M-PM-2M-QM-^KM-PM-9 M-QM-^BM-PM->M-PM-<" UUID="E8923D15923CE9A8" TYPE="ntfs"
We need UUID = "E8923D15923CE9A8"
Now add the entry to / etc / fstab
sudo nano /etc/fstab
At the very end, add
UUID= E8923D15923CE9A8 /media/files ntfs-3g defaults,acl,user,user_xattr,errors=remount-ro
* Attributes are set to your liking.
Records are separated by either a space or a tab.
Reboot:
sudo reboot
After rebooting, check
mount
NTFS drive mounted
/dev/sda1 on /media/files type fuseblk (rw,nosuid,nodev,noexec,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
Install Samba
First, update the list of repositories and search for indexes of updated versions of programs, drivers, the kernel and everything else:
sudo apt-get update
Install samba
sudo apt-get install samba samba-common-bin
There are a lot of settings in samba, but now we only need to configure the basic ones to get access to our disk.
We open the smb.conf file
sudo nano /etc/samba/smb.conf
You can delete all the many settings, or you can add the necessary settings to the appropriate sections
[global]
workgroup = WORKGROUP
guest ok = yes
netbios name = CubieNAS
security = share
browseable = yes
[files]
path = /media/files
writeable = yes
browseable = yes
Restart Samba
sudo /etc/init.d/samba restart
We try to enter
\\ CubieNAS or \\ ip.
If everything is configured correctly, we will see the files folder.
I have a gigabit network speed:
EXT4 disk.
1 Gb file is transferred at a speed of 24-29 Mb / s.
Folder with 300 files of different formats 16-34 Mb / s
Copying from a cube
1 Gb file is transferred at a speed of 26-34 Mb / s
Folder with 300 files of different formats 22-33 Mb / s
NTFS Disk
Copying to a cube
1 Gb file is transferred at a speed of 8-9 Mb / s
Folder with 300 files of different formats 3- 8 Mb / s
Copying from a cube
1 Gb file is transferred at a speed of 24-28 Mb / s
Folder with 300 files of different formats 12-27 Mb / s
Not fast, but it works.
