Managing the Target Server

Prerequisites

• You have installed and deployed the Kunpeng DevKit.
• You have installed the Kunpeng DevKit plugin and logged in to the Kunpeng DevKit using the plugin.

Procedure

• Target server management is not available in WebUI mode.
• In the VS Code, the Remember password option is displayed when you add a target server. However, to ensure your account security, do not select Remember password when logging in using a public network or public computer.

1. In the upper right corner of the page, choose > General Settings > Target Server Management. The target server management page is displayed.
2. Click Add Target Server. The window shown in Figure 1 is displayed. Set the parameters by referring to Table 1. Then click OK.

   Table 1 Parameters for adding a target server

   Parameter	Description
   IP Address	IP address of the target server to be connected.
   SSH Port	SSH port of the target server to be connected.
   Password-Free Public-Private Key Pair	The options are: Auto generation Manual generation NOTE: If you select Auto generation, the tool automatically generates a public-private key pair in a local directory and transfers the public key to the target server. If you do not need to use the public key authentication for SSH connection, delete unnecessary public keys from the ~/.ssh/authorized_key file on the server. If you select Manual generation, you need to manually generate a public-private key pair to configure the server.
   Private Key	Import the id_rsa private key file. NOTE: A key pair can be generated by running the following command: ssh-keygen [-b bits] [-t dsa | ecdsa | ed25519 | rsa] [-C comment] [-f output_keyfile] If the target server OS is openEuler 22.03, you need to use another secure encryption algorithm, such as ssh-keygen -b 521 -t ecdsa -f ${plugin_path}\\rsa\\ssh -N "${random_passphrase}", to generate a public-private key pair. If the target server OS is openEuler 22.03-LTS-SP1, you need to use another secure encryption algorithm, such as ssh-keygen -t ed25519 -f ${plugin_path}\\ed25519\\ssh -N "${random_passphrase}, to generate a public-private key pair. For other target server OSs, you need to use another secure encryption algorithm, such as ssh-keygen -b 3072 -t rsa -f ${plugin_path}\\rsa\\ssh -N "${random_passphrase}", to generate a public-private key pair. You can click the question mark (?) next to Private Key and click the copy icon in the pop-up bubble to copy the command for generating a key pair.
   (Optional) Passphrase	Enter the passphrase for generating the key.
   Upload a Public Key	Yes No NOTE: This parameter is displayed when you select Manual generation for Password-Free Public-Private Key Pair. If you select Yes, you need to specify the public key file and SSH password. If you select No, ensure that the public key has been configured on the server.
   Public Key	Import the id_rsa public key file. NOTE: A key pair can be generated by running the following command: ssh-keygen [-b bits] [-t dsa | ecdsa | ed25519 | rsa] [-C comment] [-f output_keyfile] If the target server OS is openEuler 22.03, you need to use another secure encryption algorithm, such as ssh-keygen -b 521 -t ecdsa -f ${plugin_path}\\rsa\\ssh -N "${random_passphrase}", to generate a public-private key pair. If the target server OS is openEuler 22.03-LTS-SP1, you need to use another secure encryption algorithm, such as ssh-keygen -t ed25519 -f ${plugin_path}\\ed25519\\ssh -N "${random_passphrase}, to generate a public-private key pair. For other target server OSs, you need to use another secure encryption algorithm, such as ssh-keygen -b 3072 -t rsa -f ${plugin_path}\\rsa\\ssh -N "${random_passphrase}", to generate a public-private key pair.
   OS Username	SSH user name of the target server to be connected.
   OS User Password	Enter the SSH password of the target server.
   Workspace	Path for synchronizing code to the server during remote compilation and debugging. Set this parameter properly. The default path is ~/workspace.

3. When a message is displayed indicating that the host fingerprint reliability cannot be determined, click Yes to go to the next step until the target server is added.
4. (Optional) Click Configure JSON File to add a server or modify a configured server by configuring JSON file.
5. You can click Modify, Login, or Delete in the operation column on the right of the target server after the target server is added.
