If your Windows instance can access the Internet, you can use remote connection tools to connect to it. Otherwise, you can use the Management Terminal.

Prerequisites

  • The instance is in the Running status. If not, start it.
  • You have set a logon password for the instance. If the password is lost, you can reset the password.
  • The instance can access the Internet:
    • In a VPC, a public IP address is assigned to the instance or an EIP address is bound to the instance.
    • In the classic network, a public IP address is assigned to the instance by using either of the following methods:
      • For a Subscription or a Pay-As-You-Go instance, you can select Assign public IP when creating the instance.
      • For a Subscription instance without a public IP address, you can assign one by upgrading bandwidth.
  • The following security group rules must be added to the security group that the instance joins. For more information, see Add security group rules.
    Network Type NIC Rule Direction Authorization Policy Protocol Type Port Range Authorization Type Authorization Object Priority
    VPC N/A Inbound Allow RDP(3389) 3389/3389 Address Field Access 0.0.0.0/0 1
    Classic Internet

Procedure

Based on the operating system of your local machine, use one of the following methods to connect to a Windows instance:

Windows OS

If the local machine is running Windows OS, you can use the mstsc to create a remote connection to a Windows instance.

  1. Use any one of the following methods to start mstsc:
    • Select Start > icon > Remote Desktop Connection.
    • Click the Start icon and search for mstsc.
    • Press the Windows key + R to open the Run window, type mstsc, and then pressEnter.
  2. In the Remote Desktop Connection dialog box, follow these steps:
    1. Click the Show Options drop-down box.

    2. Type the public IP address or EIP address of the instance.
    3. Type the user name. The default user name is Administrator
      Note If you want to log on to the instance next time using the same credentials, select Allow me to save credentials.

    4. Optional. If you want to copy text or files from the local machine to the instance, click the Local Resources tab to see options for sharing local computer resources.
      • If you want to copy text only, select Clipboard.

      • If you also want to copy files, select More and select the drive letters from which you want to copy files to your instance and click OK.





    5. Optional. Click the Display tab to resize the remote desktop window. Full Screen is recommended.

    6. Click Connect.

Linux

If the local machine is running Linux OS, you can use a remote connection tool to create a remote connection to a Windows instance. This article takes rdesktop as an example to describe how to connect a Windows instance from a local machine running Linux.

  1. Download and start rdesktop.
  2. Run the command to connect to a Windows instance. Replace the parameter values with your own configurations.
    rdesktop -u administrator -p password -f -g 1024*720 192.168.1.1 -r clipboard:PRIMARYCLIPBOARD -r disk:sunray=/home/yz16184

    The following table describes the parameters involved.

    Parameters Description
    -u The user name. The default user name for a Windows instance is Administrator.
    -p The password used to log on to the windows instance.
    -f Full screen by default. Use Ctrl+Alt+Enter to switched the mode.
    -g Resolution. Asterisks (*) are used for separation. If omitted, full-screen display is used by default.
    192.168.1.1 The IP address of the server that requires remote connection. Replace it with the public IP or EIP address of your Windows instance.
    -d Domain name. For example, if the domain name is INC, then the parameter is -d inc.
    -r Multimedia reorientation. For example:
    • Turn on the sound:--r sound.
    • Use a local sound card:-r sound: -r sound : local.
    • Open the U Disk: -r disk:usb=/mnt/usbdevice.
    -r clipboard:PRIMARYCLIPBOARD Realizes direct word copying and pasting between Linux and Windows instances of local devices. Supports Chinese words copying and pasteing.
    -r disk:sunray=/home/yz16184 Specifies that a directory on the Linux system of a local device maps to a hard disk on a Windows instance. If this is configured, Samba and FTP are not recommended for file transfers.

For more information about parameters of the rdesktop command, see rdesktop documentation.

Mac OS

To connect to a Windows instance from a local machine running Mac OS, see Get started with Remote Desktop on Mac.

Android or iOS

If your local machine is running Android OS or iOS, see Connect to an instance on a mobile device.
