Logging In to a Windows ECS from a Linux Computer

Scenarios

This section describes how to log in to a Windows ECS from a Linux computer.

Prerequisites

• The target ECS is running.
• The ECS must have an EIP bound.

  An EIP is not required if you log in to an ECS through an intranet using MSTSC, for example, through VPN or Direct Connect.

• Access to port 3389 is allowed in the inbound direction of the security group which the ECS belongs to.
• Data can be exchanged between the login tool and the target ECS. For example, the default port 3389 is not blocked by the firewall.
• RDP has been enabled on the target ECS. By default, RDP has been enabled on the ECSs created using a public image. For instructions about how to enable RDP, see Enabling RDP.

Procedure

To log in to a Windows ECS from a local Linux computer, use a remote access tool, such as rdesktop.

1. Run the following command to check whether rdesktop has been installed on the ECS:

   rdesktop

   If the message "command not found" is displayed, rdesktop is not installed. In such a case, obtain the rdesktop installation package at the official rdesktop website.

2. Run the following command to log in to the ECS:

   rdesktop -u Username -p Password -g Resolution EIP

   For example, run rdesktop -u administrator -p password -g 1024*720 121.xx.xx.xx.

   Table 1 Parameters in the remote login command

   Parameter	Description
   -u	Username, which defaults to Administrator for Windows ECSs
   -p	Password for logging in to the Windows ECS
   -f	Full screen by default, which can be switched using Ctrl+Alt+Enter
   -g	Resolution, which uses an asterisk (*) to separate numbers. This parameter is optional. If it is not specified, the remote desktop is displayed in full screen by default, for example, 1024*720.
   EIP	EIP of the Windows ECS to be remotely logged in. Replace it with the EIP bound to your Windows ECS.

Enabling RDP

For your first login, use VNC to log in and enable RDP for your ECS. Then, use MSTSC to log in.

By default, RDP has been enabled on the ECSs created using a public image.

1. Log in to the Windows ECS using VNC.

   For details, see Logging In to a Windows ECS Using VNC.

2. Click Start in the task bar and choose Control Panel > System and Security > System > Remote settings.

   The System Properties dialog box is displayed.

3. Click the Remote tab and select Allow remote connections to this computer.
