2.7.14 Controlling the interface of a computer during a remote control session

(1) Registering and entering special keys for use in remote control sessions

When you use your keyboard to enter special keys like function keys and keyboard shortcuts, those keystrokes apply to the controller itself. To use special keys on the remote computer, you need to register them in the controller first. Fore details about registering special keys in the controller, see the description of registering a special key with the controller in the manual JP1/IT Desktop Management 2 Administration Guide.

The special keys you register appear in the key input bar of the Remote Control window. By clicking the buttons in the key input bar, you can enter the associated special key in the remote computer.

Tip

If the controller computer and the remote computer have different input environments (for example, the controller system uses an English-language keyboard while the remote system uses a Japanese layout), you might not be able to enter certain characters using your keyboard. In this case, you can enter such characters without needing to be conscious of the different input environments by using special keys or transferring the data using the clipboard.

(3) Transferring clipboard data during remote control sessions

You can configure the remote control feature to automatically transfer clipboard data from the controller to the remote computer, or vice versa, each time the clipboard contents change. This ensures that the clipboard contents are always the same on both computers, which means you can work seamlessly between them when performing operations like the following:

• Displaying a Web site in a Web browser on the remote computer by pasting a URL recorded on the controller PC

• Paste screenshots or other data collected on the remote computer into documents being created on the controller computer

There are some differences in the types of data that can be transferred depending on the connection type.

For standard connections:

You can transfer the following types of data or any combination thereof:

• Text

• Bitmaps

• Metafiles

• Rich text

• Color palettes

For RFB connections:

You can send and receive ASCII text only. The ability to send and receive non-ASCII text depends on the environment of the remote computer.

Clipboard data is transferred when the controller window becomes active. If you are using an RFB connection, data is transferred when the clipboard contents are updated on the remote computer.

Tip

When using a standard connection, to prevent the system from slowing down when a large amount of data is copied to the clipboard, you can configure the remote control feature to only transfer text on the Optimize Transaction tab of the Environment Settings dialog box.

Tip

While clipboard data is being transferred, the system displays a message and progress bar in the status bar at the bottom of the Remote Control window. If you start transferring an unexpectedly large file that appears to be taking too long to transfer, you can cancel the transmission by right-clicking the progress bar and selecting Cancel. The data being transferred is discarded, and the clipboard reverts to its previous contents.

(4) Setting search ranges for connection-target computers

There are five ways to set the search range for connection-target computers, as described in the table below.

No.	Method	Example	Actual search range
1	Specify a single IP address.	172.17.11.10	172.17.11.10
2	Enter the first three bytes of the IP address. As the last byte, enter two numbers joined by a hyphen (-). Use this format to search within a group of consecutive IP addresses.	172.17.11.10-20	172.17.11.10 to 172.17.11.20
3	Enter the first three bytes of the IP address. As the last byte, enter several numbers separated by commas (,). Use this format to search within a group of non-consecutive IP addresses.	172.17.11.10,11,100,200	172.17.11.10,172.17.11.11,172.17.11.100,172.17.11.200
4	Use a combination of methods 2 and 3.	172.17.11.10,50-100,200	172.17.11.10, 172.17.11.50 to 172.17.11.100, and 172.17.11.200
5	Specify the first three bytes of the IP address. Use this format to search among all the IP addresses within a given subnet.	172.17.11	172.17.11.0 to 172.17.11.255

(5) Status of connection-target computers

Computers in the Search Agents dialog box can be in Awaiting connection, Connection rejected, Not running, or Not responding status. The figure below shows how a computer transitions between these statuses.

Not responding

The computer does not exist or is turned off.

Not running

The computer cannot be controlled remotely, or the remote control agent is not running on the computer.

Connection rejected

The remote control agent is running on the computer (with the agent installed), but a connection cannot be established. Possible causes include the agent not being registered as a permitted controller, and the port used by the remote control feature being used by another application. Check the message on the Details tab of the Search Agents dialog box.

Awaiting connection

The computer is ready to accept connections.
