User Manual
Appendix B
Control Configuration Settings
Control settings are specified in Control Profiles. These configuration profiles store security settings, define levels of access for Control users, and can control which Clients users are allowed to access.
To create and modify Control Profiles, choose the Tools, Configurations menu command in the Control window.
General
The General folder specifies the name by which the Control identifies itself to Clients. It also enables you to record a description of the profile.
Control Name
The name which the Control program uses to identify itself when connecting to Clients. If you leave this field empty, the Control will use the Machine Name.
Description
You can enter a description for this Control Profile here.
Title
Enter the title for any messages that are sent to Clients. It will be displayed in the caption bar of the message.
Connectivity
The Connectivity folder specifies the settings used to start and maintain connections with Clients and remote Networks.
- The Network Transport pages are listed only when you click Connectivity and Startup Settings in the Configurations dialog.
Use TCP/IP
Select this check box if you want to use the TCP/IP Windows Sockets protocol. This protocol is used in local and wide area networks, including the Internet. You may also need to specify a Port number.
Port
This port is used by the Control to communicate with Clients on TCP/IP. The default is port 5405, but you can configure Clients on your network to use a different port number if required. This can provide additional security, as any other Control users must know which port the Clients are using before they can be accessed. You can also specify the port number when Adding a new Client or connecting to a Client.
Connect by Hostname (DHCP/WINS)
Normally the Control connects to a TCP/IP Client using the IP Address stored in the Known Clients database rather than by name. However, if your environment uses Dynamic Host Configuration Protocol (known as DHCP), the address may change whenever the Client PC is restarted. Select this option forces the Control to connect by hostname. The Client's Hostname is resolved using the Windows Internet Naming Service (WINS) or if WINS fails, a Domain Name Server (DNS).
Test
Click this button to check the configuration and version of the TCP/IP stack installed. The Windows Sockets version and current state are displayed.
Subnets used when browsing for Clients
If your network has multiple subnets or addresses, you may have to configure Broadcast Addresses for each network. When you Browse for Clients, Lookup messages are broadcast to these addresses. Click the Settings button to configure the Control's Broadcast Addresses.
Enable Broadcast Show
During a Show, the Control sends screen updates to each Client in turn. Consequently, Show performance deteriorates as more Clients are included. Select this check box to use UDP Broadcast packets instead. These are sent to all Clients simultaneously so performance is not affected by the number of Clients. Click the Settings button to configure Broadcast Show.
Use IPX
Check this box to enable the IPX transport protocol. This protocol is most commonly used to network PCs in a Novell NetWare environment. It is routable and can be used on local and wide area networks.
Record Clients' Network Numbers
When you connect to a Client the Control records its network number. The Control normally obtains a list of network numbers from the nearest NetWare Server, Router, or bridge, but if the Server becomes unavailable, these network numbers will be invalid. Select this option to record the network numbers. This allows the Known Clients file (CLIENT.NSM) to be copied and used by Control machines which may be located on a different network segment. Deselect this option to store the network numbers as zero.
Use Networks
The Control normally obtains a list of network numbers from the nearest NetWare server or bridge. On some networks, there is no NetWare server to ask or the list generated is unreliable. Enter one or more network numbers to use, which replaces the normal discovery mechanism. The numbers can be in decimal or hexadecimal (indicated by a leading 0x), and must be separated by commas. For example:
You can also use the Test function to determine these values automatically.
Ignore Networks
This list of network numbers is generated in the same way as for Use Networks except that when browsing, network numbers are ignored. You can also use the Test function to determine these values automatically. This list of network numbers is generated in the same way as for Use Networks except that when browsing, network numbers are ignored. You can also use the Test function to determine these values automatically.
Test
Click this button to check the IPX network configuration. This determines if the IPX network stack is available and configured correctly. The Control can also check which network numbers respond.
Use NetBIOS
Check this box to enable the use of the NetBIOS transport. NetBIOS is a family of non-routed protocols which are normally only used on local area networks. Common examples of NetBIOS protocols are DECnet and NetBEUI. Select which of the available NetBIOS protocols should be used by choosing one or more Adapters.
Adapters
The various NetBIOS protocols are accessed through their Adapter Numbers. This list box contains the NetBIOS Adapters that have been detected in this PC. Select one or more Adapters that are to be used. Adapter numbers are not constant and vary according to the order of installation of drivers. Consequently, they vary from one PC to another and from one Client to the next.
Test
Click this button to determine which NetBIOS protocols are available on this PC.
Use HTTP
Select this check box to enable the HTTP protocol that is used to communicate with the Gateway.
Port
The Gateway normally listens for Clients and Controls on port number 3085. The value can be changed here.
Test
Click this button to check that the HTTP transport is working.
- The Control stores further settings for individual Gateways in the Gateways Folder.
Modem
Select one of the installed modems from this drop-down list. If there are no modems installed, you can add one using Start, Settings, Control Panel, Modems.
Dual Channel Bonding
Select this check box to use both lines on an ISDN Terminal Adapter for the same Client-Control channel.
Multiple Subscriber Numbers (MSN)
ISDN lines can be used with more than one telephone or subscriber number. This field allows you to specify which numbers should be used to dial. Similarly, when a call is received, the telephone number is notified. Use this field to restrict responses to one or more specific telephone numbers.
Diagnostics
None Select this option to perform no diagnostics on your modem. Use this if the Basic or Extended settings prevent your modem from communicating properly.
Basic When the modems connect, the Control checks the following:
- Flow control is correctly set (XON/OFF is disabled, etc.)
- There is a PC-Duo Bridge at the remote number
- There are not excessive delays in transferring data
Extended The Extended setting performs the same checks as for Basic and includes:
- The PC to Modem baud rate is compatible with the Modem to Modem baud rate
- Line reliability
- Throughput
Logging Level
None Select this option to display the progress messages on the screen only.
Basic Selecting Basic logs the following information to MODEM.LOG:
Verbose Selecting Verbose records the same information as Basic, but includes information about the modem retrieved from the modem itself
Use this option is you are having problems establishing dial-up links.
View Log
Opens a window that displays the MODEM.LOG file generated by Extended and Verbose Diagnostic and Logging settings.
Tickle Period
This setting controls the period in seconds between the keepalive or tickle packets that are sent to the Client to make sure that a Control to Client connection is still operational. If the Client does not respond, the Control will close down the connection. You can disable tickle packets altogether by entering 0 (zero).
Name Lookup Delay
This setting controls the delay in seconds between broadcast packets when a Control is Browsing the Network for Available Clients. This value is used in conjunction with Name Lookup Attempts to change the time required to Browse. The Control is more likely to miss Clients if this value is too small.
Name Lookup Attempts
This controls the number of times the Control broadcasts a name lookup packet when it is Browsing the Network for Available Clients.
- Reducing the Name Lookup Delay and the number of Name Lookup Attempts will send less broadcasts on the network, and the browse will complete more quickly. However, do not specify values of Name Lookup Delay and Name Lookup Attempts such that the result when multiplied together is less than 4 seconds.
Security
The Security folder specifies the password required to access the Control Profile and the Security Key that controls which Clients the Control can access. It also specifies whether the Control has access to administrative functions, logs events and records actions performed on Clients during Control sessions.
Password
Click the Set button to password protect the Control program. Anyone starting the Control using this Profile must enter this password or the Control will not run.
Security Key
Click the Set button to change the Control's Security Key. This is used whenever you connect to a Client. The key entered here must match the Security Key on the Client, or you will not be allowed to access the Client machine.
Prompt for Additional Information when connecting
Select this box if you want to supply a reason for connecting to a Client. This message is displayed at the Client when the Client has User Acknowledgement enabled. It shows the user why you are connecting to their PC. If the Client also has logging enabled, the reason is recorded in the log file.
Try last username before displaying login prompt
Select this check box to save usernames and passwords from successful connect attempts. They will be tried the next time the Control tries to connect to the Client. If the details are still valid, this eliminates the need to enter them again.
Use Compression
When this check box is selected, all data sent to and from the Client will be compressed. This typically reduces the amount of network bandwidth required for the remote control session and improves performance over a slow connection. However, compression and expansion increase the processor load at both Control and Client and this can reduce performance in a fast network.
Use Encryption
Select this check box to enable encryption on all keyboard, mouse, screen, and file data transfers. Several algorithms are available:
- 56-bit Data Encryption Standard (DES)
- 64-bit Blowfish
- 128-bit Twofish
- 256-bit Advanced Encryption Standard (AES)
Select an algorithm appropriate to your security requirements. Longer key length algorithms typically require additional processing power and so give reduced performance remote control.
- The Control will warn you when connecting if the selected encryption algorithm is not supported, such as by an older version Client.
Enable Logging
Select this check box to enable Control logging.
Log to File
The Control Log is written to a file. You can specify the file name here.
As User
If the file is located on a Server, you may have to enter a username and password to access the file. Click Set to open the Add/Edit User dialog.
Append to Logfile
Select this check box to preserve the log contents from one Control session to the next.
Record Replay Files
Select the Record Replay Files check box to enable Replay recording by the Control and specify the output location or click Browse to locate the directory for the resulting Replay Files.
When this configuration is used, the Control will record all remote control sessions in the specified location. This setting takes effect when you next open a remote control View Window.
The Replay Files can be viewed later using the Tools Menu, Replay command.
Include Audio
This option allows you to store audio information in the Replay File.
Prefix Files with Client Name
When this check box is selected, Replay Files are created using the Client's name, followed by the date and time. This allows individual Clients' Replay Files to be recognized when they are stored in the same directory.
In Directory
Specify the output location or click the Browse button to locate the directory for the resulting Replay Files.
These settings restrict the items that users of this Control Profile can modify. They can only be changed by an Administrator.
Act as an Administrator
When this check box is selected, users of this Control Profile can make any configuration changes that they wish. This should be selected for at least one Profile, to allow them to alter other Profile settings.
Change Settings
This check box is only accessible when the Act as an Administrator setting has been cleared. Clear this check box to prevent users of this Control Profile from changing any settings.
Configure User Interface
This check box is only accessible when the Act as an Administrator setting has been cleared, but Change Settings is selected. Clear this check box to prevent users of this Control Profile from altering any settings that affect the Control's User Interface.
Remote Control
The Remote Control folder specifies the keyboard, mouse, and printer functions that the Control user can access on Client PCs when running remote control sessions. It also specifies the Control's audio settings and the level of detail shown in the Client screen when it is displayed on the Control PC.
BIOS Keyboard
This option causes DOS Clients to emulate keystrokes at the BIOS level rather than at the hardware interrupt level. You should only use this setting if an application at the Client does not appear to be accepting keystrokes from the Control.
Confirm Switch to Full Screen
When this box is selected, you will be prompted to confirm switching to full-screen mode.
Full Screen
Check this option to view a Client in full-screen mode rather than windowed mode.
Scale to Fit
Check this option if you want the Client's screen shrunk to fit the View Window.
Disconnect when Closed
When this check box is selected, the Control will disconnect from the Client when the View Window is closed. This can be useful if you normally only use remote control and forget to disconnect from a Client when you have finished working with it. You can also configure the Control to exit when the View Window is closed. See Settings for Configuration: Startup for more details.
Screen Scrape
Select this check box to view the Client in Screen Scrape mode, reading the display contents from the adapter memory. This method can be used when the Client is running software that is not compatible with the normal GDI intercept method, but it is less efficient and this has a considerable effect on remote control performance.
Scrollbars
You can turn off scroll bars on the view windows by deselecting this check box. This can be helpful with Auto-Scrolling, as it gives you a little more workspace.
Use Compression
This check box controls data compression when Viewing. Compression is compute-intensive, and you may obtain better performance by disabling it on a fast network or with slow PCs. This check box is also accessible in the Settings for Configuration: General tab.
Wallpaper
Check this box if you want to leave the Client's wallpaper visible while viewing. Normally, wallpaper is turned off to improve performance, but this may disturb the Client user. Screen update speed will be reduced if this option is enabled.
Blank Client Screen
Select this check box to blank the Client's screen when you are viewing it.
Video Skipping
This check box enables Video Skipping. This can be used to improve remote control performance.
Default Mode
When you start viewing a Client, by default you start in Share Mode. If you prefer to start viewing in a different mode, choose from this list.
Cache Size
The Control and Client use a cache to help improve performance when the Client is running applications that use lots of or large bitmaps. The cache size can be in the range 1MB to 16MB. A separate cache is allocated to each Client. Increase the cache size to improve performance.
Max Colour Depth
This setting restricts the color depth of the screen data that is sent to the Control when it is viewing a Client. It is used to reduce the amount of traffic between Clients and Controls. Reduce the color depth to 16 colors is you are using applications that do not rely on anything other than the 16-color palette.
Change DOS Font
Click this button to change the font used when the Control is viewing a DOS application running on the Client, either on DOS, or in a full-screen DOS box. (Windows uses a graphic character set to display DOS screens. You may have to change the font size to get an accurate representation of the DOS Client.)
Change Japanese Font
Click this button to select the font when displaying Japanese DOS applications.
Update Configuration
If the Update Configuration check box is selected, the current Control Profile will be updated with any changes made in this tab.
Keyboard Layout
This list provides alternative keyboard layouts that can be used when the Control is viewing a Client. The Layouts map keys on the Control's keyboard to others on the Client.
The default is Unmapped Keyboard. this is used when both the Control and the Client have the same keyboard layout.
Hotkeys
When you are viewing a Client in full-screen mode, Hotkeys provide a way to switch back to window mode. Check the boxes in this group to determine the keys that are used as Hotkeys.
Autoscroll speed
When you are viewing a Client's screen, the Control can automatically scroll the View when the mouse moves close to the edges of the window. This control sets the speed at which the View scrolls.
Scroll Delay
When Auto-scroll is enabled, this control changes the delay before scrolling starts. If you want the View to scroll as son as the mouse is at a screen edge, move the slider towards Min. If you prefer a longer delay, move the slider towards Max.
Mouse Delay
This slider controls the rate at which the mouse position updates are sent from the Control to the Client when Controlling or Sharing. This is useful of dial-up or very slow networks. Move the slider towards Infinite to reduce the rate and conserve bandwidth, or towards Min for the best mouse response.
Disable Num lock synchronisation
When this check box is selected, the Control does not adopt a Client's Num Lock setting during a remote control session.
Enable Print Capture
Check this box to enable Print Capture. The Client's printer output will be captured and printed at the Control.
Capture to Printer
Select this radio button to redirect the Client printing to a local or network printer. Click the Change button to select one of the printers installed on the Control PC.
Capture to File
Select this radio button to redirect the Client's printer output to a file. This file can on a local or network path. Click the Browse button to select a location for the file.
Use Client Printer Driver
On Windows 95 and Windows NT, the user can change the printer name (in Control Panel, Printers or Start, Settings, Printers). To handle this situation, and because printer and driver names vary between Windows 3.x, Windows 95 and NT, you can specify a list of printer names and drivers in this field. For example:
HP DeskJet 520,DESKJETC; HP DeskJet...HP DeskJet 520 is a printer name that the Client might recognize
DESKJETC is the name of the driver file for this printer at the Client (optional, .DRV assumed)
HP DeskJet is another printer name that the Client might recognize
When Print Capture is enabled, the Control sends this information to the Client, and the Client then looks for the closest match in the drivers installed on the Client machine. The NT Client ignores the name of the driver file; the Windows and Windows 95 Clients match this preferentially, using the printer name only in the event of a tie.
Report Driver Used
When you connect to a client a dialog box will appear informing you of the printer driver that has been used. If no matching drivers were found, you would be informed whether you check this box or not.
Threshold
Use this slider to control the lowest sound level that is sent through.
- If this is set too high, the user at the other end will hear broken up sounds. If it is set too low, more data than strictly necessary will be transferred, reducing remote control performance.
