Login Using VNC¶
Scenarios¶
This section describes how to use VNC provided on the management console to log in to an ECS. This function applies to emergency O&M. In other scenarios, you are advised to log in to ECSs using SSH or MSTSC.
Constraints¶
The remote login function is implemented using customized ports. Therefore, before attempting to log in remotely, ensure that the port to be used is not blocked by the firewall. For example, if the remote login link is xxx:8002, ensure that port 8002 is not blocked by the firewall.
If the client OS uses a local proxy and the firewall port cannot be configured on the local proxy, disable the proxy mode and then try logging in remotely.
Login Notes¶
When you log in to the ECS using VNC, four types of keyboards will be used. These are described in Table 1.
Table 1 Keyboard types¶ Keyboard Type
Description
Keyboard Language
Physical keyboard
Used by the terminal and allows terminal data input.
Selected by users locally.
Input method keyboard on the terminal
Used for logging in to the management console from a terminal, such as a computer. The keyboard input method of the terminal must comply with the physical keyboard language type. In this way, the entered data can be correctly transferred from the physical keyboard to the VNC client.
Selected by users locally.
VNC keyboard
Used for VNC logins. The VNC keyboard input method must comply with the physical keyboard language type. In this way, the entered data can be correctly transferred from the VNC client to the ECS OS.
Note
The English keyboard is used by default. The system also supports other keyboard languages.
Can be configured through the management console.
For instructions about how to select a VNC keyboard language, see Log In to a Windows ECS Using an English Keyboard and Log In to a Windows ECS Using a Non-English Keyboard.
ECS OS keyboard
Input method keyboard configured in the ECS OS. Ensure that this input method complies with the physical keyboard language type for correct response to the entered data transferred from the VNC client.
Note
The default OS keyboard language of an ECS created using a public image is English.
The OS keyboard language of an ECS created using a private image is customized.
Configured by users locally.
For instructions about how to change an ECS OS keyboard language, see Changing the OS Keyboard Language.
When you log in to the ECS using VNC, ensure that your configured keyboard language is correct.
The entered data is as expected only if the input method keyboard on the terminal, the VNC keyboard, and the ECS OS keyboard languages are the same as the physical keyboard language. For details about language configuration in the four types of keyboards, see Table 2.

Click
in the upper left corner and select your region and project.Under Computing, click Elastic Cloud Server.
Obtain the password for logging in to the ECS.
Before logging in to the ECS, you must have the login password.

Configuration Example¶
Scenarios
If you attempt to log in to an ECS created using a public image for the first time, the languages of the four types of keyboards before the configuration are as follows (Before configuration row in Table 3):
Physical keyboard: German
Input method keyboard on the terminal: English
VNC keyboard: English
ECS OS keyboard: English
In this case, you must change the languages of the other three types of keyboards to the same language as the physical keyboard for expected data entering. For details, see the Solution 1 row in Table 3.
| Physical Keyboard | Input Method Keyboard on the Terminal | VNC Keyboard | ECS OS Keyboard |
|---|---|---|---|---|
Before configuration | German | English | English | English |
Solution 1 | German | German | German | German |
Solution 2 | English | English | English | English |
Procedure
Locally configure the language, for example, German, in the input method keyboard on the terminal.
Set the VNC keyboard language to English.
Note
When you log in to the ECS using VNC for the first time, the default ECS OS keyboard language is English. Therefore, you must set the VNC keyboard language to English.
Log in to the ECS and change the ECS OS language to German.
For details, see Changing the OS Keyboard Language.
Change the VNC keyboard language to German.
For details, see Log In to a Windows ECS Using a Non-English Keyboard.
To set the languages on the four types of keyboards to all be the same, repeat steps 1 to 4.
Note
During the configuration, if English characters cannot be entered using the current physical keyboard, use the English soft keyboard to modify the configuration described in the Solution 2 row of Table 3. In such a case, you only need to use the English soft keyboard to enter characters.
To enable the Windows English soft keyboard, choose Start > Run, enter osk, and press Enter.
The method of enabling the Linux English soft keyboard varies depending on the OS version and is not described in this document.
