Adjust the time zone to the local area, once connected to the internet, the time will be updated synchronously.

(1)Open PuTTY and enter the IP address of DEBIX to log in.
(2)When you first log in you need to confirm the connection key, please press "Yes" to confirm. This prompt only appears when logging in for the first time.
(3)After logging in, you will be prompted to enter the user name and password, and then you can log in to the DEBIX command line.
(Note: the default DEBIX user name/password is debix/debix)

(1) Find the sshd service configuration file sshd_config in the /etc/ssh/ directory and open it with the Vim editor; remove the "#" before the monitor port and monitor address in the file; then enable the remote login; finally, enable the use of user name and password as connection verification; save the file and exit
(2) If the connection fails, please enter ps -e | grep sshd to check whether the sshd service is enabled
(3) In order to avoid manual start of sshd service every time at startup, you can add the sshd service to the self-starting list and enter systemctl enable sshd.service
(4) You can enter systemctl list-unit-files | grep sshd to see if the sshd service is set to start automatically

From the desktop, Settings----Region & Language, add the Input sources in Input Sources option, then you can switch between the keyboard layouts.

Read the SD card which has finished flashing with a computer. Create a new wpa_supplicant.conf file in the boot partition (DEBIX's /boot directory), fill in the content according to the following reference format and save the wpa_supplicant.conf file.
1 country=CN
2 ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
3 update_config=1
4
5 network={
6 ssid="WiFi-A"
7 psk="12345678"
8 key_mgmt=WPA-PSK
9 priority=1
10 }
11
12 network={
13 ssid="WiFi-B"
14 psk="12345678"
15 key_mgmt=WPA-PSK
16 priority=2
17 scan_ssid=1
18 }
Instructions and configuration examples of WiFi with different security:
#ssid: ssid of the network
#psk: password
#priority: Connection priority, a larger number means higher priority (a negative number is unacceptable)
#scan_ssid: You need to specify the value to 1 when connecting to hidden WiFi
If your WiFi has no password
1 network={
2 ssid="name of your wireless network（ssid）"
3 key_mgmt=NONE
4 }
If your WiFi uses WEP encryption
1 network={
2 ssid="name of your wireless network（ssid）"
3 key_mgmt=NONE
4 wep_key0="your wifi password"
5 }
If your WiFi uses WPA/WPA2 encryption
1 network={
2 ssid="name of your wireless network（ssid）"
3 key_mgmt=WPA-PSK
4 psk="your wifi password"
5 }
If you are not sure about the WiFi encryption mode, you can open /data/misc/wifi/wpa/wpa_supplicant.conf through root explorer on your Android phone to view the WiFi information.
If the Access denied prompt appears when connecting to DEBIX via ssh, it means that the ssh service is not enabled. If you want to enable it manually, you can create a new file (a blank file is acceptable) in the boot partition like WiFi configuration and name it ssh (use lowercase and do not have any extensions).

Use the network segment scanning tool, the software will automatically detect the network segment where the computer is located, and automatically determine the scanning range. (For example, the computer IP is 192.168.1.101, and the scanning range is 192.168.1.*), find the device whose manufacturer is "DEBIX".
If you have the login authority of the router (such as home network), you can also directly query the IP address assigned to DEBIX by the router on the management interface of the router.

Open settings - audio

(1) Install vsftpd 
sudo apt-get install vsftpd 
(2) Restart the vsftpd service
service vsftpd restart
(3) Access DEBIX via FTP on the PC side
Enter in the address bar: ftp:\\192.168.1.x(substitute the IP address with your DEBIX IP)
Enter user name and password as prompted

Create a *.service file (* is the service name, such as myscript.service)
Use root user and save this file to the /etc/systemd/system directory:
sudo cp myscript.service /etc/systemd/system/myscript.service
Then you can try to start the service with the following command:
sudo systemctl start myscript.service
Stop the service:
sudo systemctl stop myscript.service
Set automatic run at boot:
sudo systemctl enable myscript.service
The systemctl command can also be used to restart or disable it.
