There could be various reasons for the failure to establish an SSH remote connection to the server. Here are some common troubleshooting steps for identifying the causes of the issue.<\/p>\n

    \n
  1. Check the local network connection first and try pinging the server to see if it can be reached.<\/li>\n
  2. The SSH service is not running: Check if the SSH service is started on the server, you can use the systemctl command to check the service status.<\/li>\n
  3. Firewall configuration: Verify the server’s firewall settings to ensure that the SSH port (default is 22) is open, and configure it using the iptables or firewalld commands.<\/li>\n
  4. SSH configuration file: Verify the SSH configuration file on the server (usually located at \/etc\/ssh\/sshd_config) to ensure that the settings are accurate. Pay particular attention to the following configuration options:<\/li>\n
  5. Port: Ensure the correct port is being used for SSH.<\/li>\n
  6. AllowRootLogin: Confirm whether the root user is allowed to login via SSH.<\/li>\n
  7. PubkeyAuthentication: verifying if public key authentication is enabled.<\/li>\n
  8. PasswordAuthentication: Verify if password authentication is enabled.<\/li>\n
  9. Confirm that the local SSH key is configured correctly. You can use the ssh-keygen command to generate a public and private key, and then add the public key to the server’s ~\/.ssh\/authorized_keys file.<\/li>\n
  10. User permission issue: Check if the user has SSH access rights for remote connection, you can edit the \/etc\/sudoers file using the visudo command to ensure the user has the necessary permissions.<\/li>\n
  11. Log File: Review the SSH log files on the server (usually located at \/var\/log\/auth.log or \/var\/log\/secure) to search for any error messages related to failed connections.<\/li>\n
  12. Restart SSH service: If none of the above steps resolve the issue, you can try restarting the SSH service on the server by using the command systemctl restart sshd.<\/li>\n<\/ol>\n

    If the issue cannot be resolved, it is recommended to consult the official documentation of the SSH service or seek advice from relevant technical support personnel.<\/p>\n","protected":false},"excerpt":{"rendered":"
