Configuring the Environment for Remote Access

After the Windows and Ubuntu development environments have been set up, perform the following operations to enable Windows to remotely access Ubuntu, which is required to transfer images for burning.

Installing the SSH Service and Obtaining the IP Address for Remote Access

1. In Ubuntu, open the Terminal tool and run the following command to install the SSH service:

   NOTE

   If the command fails to be executed and the system displays a message indicating that the openssh-server and openssh-client depend on different versions, install the openssh-client of the required version (for example, sudo apt-get install openssh-client=1:8.2p1-4) as prompted on the command-line interface (CLI) and run the command again to install the openssh-server.

   sudo apt-get install openssh-server
   

2. Run the following command to start the SSH service:

   sudo systemctl start ssh
   

3. Run the following command to obtain the IP address of the current user for remote access to the Ubuntu environment from Windows:

   ifconfig
   

   NOTE

   If the message "command-not-found" is displayed after you run the ifconfig command, run the sudo apt-get install net-tools command to install net-tools and obtain the IP address again.

   

Installing Remote SSH

1. Open Visual Studio Code in Windows, click , and search for remote-ssh in the Extension Marketplace.

   

2. Click Install next to Remote-SSH to install the tool. After the installation is successful, Remote-SSH is displayed on the INSTALLED list.

   

Remotely Connecting to the Ubuntu Environment

1. Open Visual Studio Code in Windows, click , and click + under SSH TARGETS.

   

2. In the Enter SSH Connection Command text box, enter ssh username@ip_address, where ip_address indicates the IP address of the remote computer to be connected and username indicates the account name used for logging in to the remote computer.

   

3. In the displayed dialog box, select the default first option as the SSH configuration file.

   

4. Under SSH TARGETS, find the remote computer and click to start it.

   

5. In the displayed dialog box, select Linux, select Continue, and enter the password for logging in to the remote computer.

   NOTE

   To eliminate the need for frequently entering the password for logging in to the remote computer, set an SSH public key.

   

   After the connection is successful, the plug-in is automatically installed in the .vscode-server folder of the user directory on the remote computer. After the installation is complete, reload Visual Studio Code in Windows as prompted. Then you can develop, compile, and burn source code in DevEco Device Tool on Windows.

   NOTE

   If your computer has DevEco Device Tool 3.0 Release or an earlier version installed, the plug-in may fail to be installed, in which case the dialog box shown below stays in the lower right corner of Visual Studio Code. If this is the case, follow the instructions in Fixing the DevEco Device Tool Installation Failure.

   

The environment for remote access is now set up. As shown below, the IP address of the remotely connected computer is displayed in the lower left corner.
