Overview
The DS Management Software suite is used to manage DS, DSR and CPS network appliances and SPC power control devices.
The DS Management Software suite is comprised of three components:
• DSView ™ - A Win32 ® application that allows DS users to manage target devices through Avocent network appliances. The Client allows for IPbased video, serial and power management sessions. DSView consists of a node manager, video viewer and Telnet viewer.
• DSAdmin - A graphical application used to create and alter DS topology and permission information that is stored on a DSAuth Server.
• DSAuth (DS Authentication Server) - A central repository for DS topology information, DS user permissions and centralized services such as authentication, access control, audit, DS appliance monitoring and
Client/DS appliance updates. DS users may specify a backup authentication server in addition to the primary server.
The DS Management Software suite includes secure, browser-based access to virtually any device in the data center, including access to all major server platforms and serial-based devices.
The following fi gure illustrates an example system confi guration using the DS
Management Software suite. For more information on how the components of the DS Management Software suite work together, see Appendix B.

DSView will automatically adjust the display if the window size changes during a session as long as autoscaling is enabled. When a DS user accesses a channel via sharing, the display will be adjusted to match the input resolution of the first person to access that channel.
To set the default remote session window resolution:
1. Load the DSView software. This will activate the Node Manager and provide you with a list of target devices that you may access. you wish to use. Available resolutions are:
• None
• 800 x 600
• 1024 x 768
Setting the color depth
The DSR Dambrackas Video Compression™ (DVC) upgrade enables DSView users to adjust the number of viewable colors in a remote session window.
You may choose to display more colors for the best fidelity, or fewer colors to reduce the data transferred on the network.
NOTE: The DSR DVC upgrade is standard on all newer DS/DSR appliances. Older DS/DSR appliances use standard video compression. For DSR DVC upgrade purchase information, contact
Avocent Technical Support or your Avocent reseller.
Remote session windows can be viewed using the best color available
(slower updates), the best compression (fastest updates), a combination of best color and best compression or in grayscale.

Sharing or Terminating a Device Session
If at any time the channel to which you are connecting is already in use, you will receive a notification message and have the choice of two options:
• You may access a port with other users and share the device session.
• If you have Administrator privileges, you may disconnect other users from a port and terminate the users’ device session.
Chapter 3: Basic Operations
31
Sharing a device session
When you attempt to access a port already in use, you will receive a notification message that the port is in use along with the name of the current DS user(s). At this point, you may request to share access to the port with the current DS user(s). The DS users that are currently active will receive a request to allow sharing. If they confirm, the new DS user will gain access to the port.
When sharing access to a port, all DS users may monitor the port and may take control if no other DS user is currently active.
When you attempt to connect to a port, the DSView Connection Sharing dialog box displays. If you select the Stealth Connection checkbox and then click
Share, the DS user that is currently active will not receive notification that access is being shared and no request to authorize sharing will be made.
NOTE: The only way to prevent a stealth connection to a port is by enabling Privacy mode.
Up to 12 DS users may share a single port at one time. If a 13th DS user attempts to connect, an error message will inform the DS user that no sessions are available. Administrators will be given the option of terminating a DS user session.
At any time, DS users may select View - List of Shared Users to view a list of
DS users sharing their port or channel. DS users in Stealth mode are excluded from this list.
Session time-out
A remote session will time-out if there has been no activity in a Session window for a specified time. The session time-out value is configured by your
Administrator by selecting Options - System Settings in the DSAdmin window.
You may override this value within the DSView. If you specify a new time-out value, it will be used the next time DSView is started.
To change a remote session time-out value:
1. From the Node Manager, select Tools - Settings, enabling the Program Settings dialog box to appear. Click the General tab.
32
DSView Installer/User Guide
2. Select one of the following from the General tab:
• Default System Timeout Values - The value set by an Administrator and stored on the DSAuth Server (default).
• No Timeout - A remote session will never time-out due to inactivity.
• Timeout Value - A remote session will time-out after the number of minutes of inactivity specifi ed. Type a number from 1-60 in the Minutes fi eld.
3. Click OK to save the settings.
Terminating a target device session
If you have Administrator privileges and the target device you are attempting to access is currently being viewed by a local DS user, DSView allows you to disconnect the local DS user so that you may access that target device. To terminate a local DS user’s session, you must first specify the ability to do so in
DSAdmin’s System Settings dialog box.
When you choose to terminate a local DS user’s connection, a message box will display prompting you to confirm the termination. The local DS user will receive a notification message when you click Yes in the message box. Control of the port is then transferred to you.
Administrators may also disconnect a DS user by selecting the port that the user is accessing and choosing File - Disconnect, or by right-clicking on the port and selecting Disconnect in the DSAuth window.
NOTE: You cannot preempt a local user that is in Broadcast mode. See the DSR Installer/User
Guide for additional information.
To specify settings to terminate the local DS user session:
1. Select Options - System Settings in the DSAdmin window. The System
Settings dialog box will appear.
2. Select the DSR Local Port Session Termination Enable checkbox in the area.
Chapter 3: Basic Operations

termination of the DS user session. Click OK. The current DS user will then receive a notifi cation message.
Rebooting and Changing Power States
If you have Administrator privileges, you may perform a warm reboot on a DS appliance at a remote location.
To reboot a remote DS appliance:
1. Select the DS appliance in the DSAdmin window.
Changing the SPC device power state
NOTE: To change the power state of a target device powered by an SPC, the SPC must be connected to a CPS810 or CPS1610 appliance. For more information on connecting an SPC to a CPS appliance, see the SPC Installer/User Guide.
The power state of either a particular SPC device, CPS appliance or server powered by an SPC device may be turned on or off. The SPC may also be used to reboot a server.
To change the SPC device power state:
1. Load the DSView software. This will activate the Node Manager and display a list of DS appliances with ports linked to SPC devices that you may access.
2. Select an SPC, then right-click on the item and select Power State from the shortcut menu. This will open the Power State dialog box with the current power state of the SPC selected. If a CPS port is linked to one or more SPCs, these linkages will appear in the dialog box.

Changing the System Settings
Depending on the level of security that you require, certain settings may be configured via the use of DSAdmin’s System Settings dialog box. These options may be accessed by selecting Options - System Settings.
Changing the remote session window time-out
DSView may be configured to automatically log a DS user out after a specified inactivity period. Use this feature to heighten security or prevent a DS user from blocking access to a channel by forgetting to log out. To change the timeout, select the Enable checkbox, then enter the desired inactivity period within the provided field. You may also disable this feature by unselecting the
Enable checkbox.
Limiting DS user port information
When a DS user attempts to select a channel that is in use, DSAdmin will report who is currently using that channel and offer DS users with administrative rights the option to log the current user out. If the Administrators only box is selected, this message will be limited to Administrators; DS users without Administrator access will only receive a message that the port is in use.
Connection sharing
By default, the DS Management Software is set to prompt connected users to allow sharing of their session. When the box marked Allow Shared Connec-
tions Automatically is checked, sharing will be initiated without a prompt.
Automatic creation and deletion of audit logs
Administrators may specify the following:
• The directory where the audit log fi le is stored (default is root).
• How long the audit log fi le is stored before it is deleted. If you do not wish to have logfi les automatically deleted, enter a Ø in the provided fi eld.
NOTE: Allowing logfi les to build for an extended period may consume a great deal of disk space.
Routine deletion is recommended.
38
DSView Installer/User Guide
NOTE: When changing the location of the Audit log, the Administrator must make sure that the full path chosen exists, is accessible to both the primary and backup DSAuth Servers and is mapped to the same letter for both machines. If the log fi le is moved to a location other than the local system, both the primary and backup DSAuth Servers will use the same location for the fi les.
Port status polling frequency
This option, when enabled, allows Administrators to configure how often
DSAuth polls appliances and how often DSView polls DSAuth. Entering a Ø in a field will disable polling on that field.
DS Management Software suite update
In order to ensure that all DS users have the latest version of the DS Management Software suite, Administrators may specify a system wide software suite version number.
To specify a version number:
1. Enter the desired DSView update version in the Update version text box.
2. Enter the IP address of the TFTP server where the update resides.
3. If you wish to make updates mandatory, click the Update is
mandatory checkbox. If Update is not selected, the DS user must upgrade
DSView software manually. See Updating Firmware later in this chapter for more information.
When a DS user with an older version of the DS Management Software suite logs into the system, the user will receive an upgrade prompt. Selecting Yes will begin the upgrade process. If the upgrade is mandatory, DS users with older versions of the DS Management Software suite will not be able to access the system until the upgrade is performed.
Terminating a DSR appliance local port session
If the Enable checkbox has been selected in the DSAdmin System Settings, a user with Administrator privileges may terminate a local port session.

Configuring SNMP trap logging
DSAuth may be configured to log enterprise (SNMP) traps sent by
DS appliances.
NOTE: SNMP trap logging cannot be enabled if SNMP services has not been installed.
All SNMP Traps are logged in the DS[mm][yy][dd].csv audit log file, where
[mm] is the month, [dd] is the day and [yy] is the year when log entries were last added.
The audit log file contains the following columns:
• DATE - Date of the log entry
• TIME - Time the log entry was made
• EVENT TYPE - Type of log entry, which is 9 SNMP_TRAP for SNMP traps
• USERNAME - Username of the user who created the trap, or “Unknown
Username” if the username is not given
• DEVICE_PORT - Displays the following for SNMP traps:
Appliance:[appliance name]::[appliance IP address]:
[community of the trap]
• DESCRIPTION - Displays the following for SNMP traps:

5. Specify the pathname for the audit log fi le in the File Location text fi eld.
- or -
Click Cancel to exit the dialog box without saving.
Configuring the Event Log
The DS Management Software suite uses the DSAuth component’s functionality to log event information in a text file that may be audited at a later time.
Events logged by DSAuth include:
• Failed DSAuth authentication attempts. (For example, the error message
Channel Blocked, insuffi cient right access may be output to the event log.)
• Server power state changes
• Appliance reboot requests
• SNMP alerts defi ned by the appliance’s fi rmware
When all software programs are installed, a modification to the event log of the computer running DSAuth is required.

Altering Settings in DSView
Under most circumstances, the DS Management Software will function smoothly with the default settings. However, depending on your system, you may wish to fine tune some aspects of its performance.
Changing your default desktop size and window scaling
There are occasions when you may wish to change the resolution on your desktop to one resembling the host DS/DSR appliance.
To change your remote session window resolution:
1. Select Tools - Desktop from the command bar at the top of the remote session window.
44
DSView Installer/User Guide
2. Choose a resolution. Your desktop will be resized to the resolution specified. Repeat this command to return to your original resolution.
DSView also supports a user-defined default window size that is applied to every software session.
To change the default window resolution:
1. From the Node Manager select File - Default Session Window Resolution.
2. Choose your default window size. Choosing None disables this feature.
Once a DS user with a default window size has connected to a port, additional
DS users will have their default displays overridden to match the first DS user.
This will prevent the first DS user’s display from being affected.
If the target device’s resolution changes any time during a session, the display will be adjusted automatically.
Creating and Using Keyboard Macros
Since DSView is running on a PC, certain commands must be sent to the controlled target device via keyboard macros. For example, pressing
Ctrl+Alt+Delete on your keyboard would reset the PC running DSView rather than resetting the target device. To reset the target device, a macro is needed.
Your software comes with numerous sequences pre-configured for ease of operation.
Local and Global Macros
Two kinds of macros are available:
• Local Macros - Local macros are created on the local computer by selecting Tools - Keyboard -Macros in the DSView Client Node Manager window.
Local macros may be customized and grouped in any manner you wish.
• Global Macros - Global macros are created and maintained by DS users with Administrator privileges by selecting Options - Keyboard Macros in the DSAdmin window and are stored on the DSAuth Server. They cannot be modifi ed by non-administrative DS users. Global macros are also stored on any backup servers that you have specifi ed.
When a session is started, you may choose to use either local macros or global macros and switch between using them at any time during the session. If you choose to use local macros, the macros stored on the local computer will be
Chapter 4: Advanced Operations
45
used. If you choose to use global macros, a temporary copy of the global macro file will be transferred to DSView from the DSAuth Server.
To use local macros, go to the DSView Client Node Manager window and select Tools - Keyboard - Local Macros. To use global macros, go to the Node
Manager window in the DSView Client and select Tools - Keyboard - Global
Macros.
Displaying/editing macro selection buttons
You may access a list of local programmed keyboard macros by selecting
Tools - Keyboard - Macros from your Node Manager window. To access a list of global programmed macros, select Tools - Keyboard - Macros from your DSAuth window. Each programmed macro will have a checkbox by it. Checked local macros or checked global macros will appear at the top of remote session windows, depending on which have been chosen for use in the
Node Manager.
Figure 4.1: Keyboard Macro Configuration Dialog Box
Sending keyboard macros
You may send a macro command by either clicking on the macro buttons in the remote session window or selecting it from the macro list and clicking the
Send button.

DSView Installer/User Guide
Programming a keyboard macro
If you require a key sequence that is not pre-programmed into the DS/DSR appliance, you may add a macro by performing the following steps.
To add a macro:
1. From the Node Manager window, select Tools - Keyboard - Macros to add a local macro.
- or -
From the DSAuth window, select Options - Keyboard Macros to add a global macro.
2. A menu will appear listing the currently available macros. Click on the Add button in the upper right-hand corner.
3. The Keyboard Macro Configuration menu will appear.
4. Enter a unique description for the macro in the Macro Description field.
5. In the Double-click for Key Press list, double-click the first keystroke of your macro. This will move the keystroke to the Double-click for Key
Release list.
6. If this key needs to be released before the next keystroke is entered, doubleclick the keystroke in the Double-click for Key Release list to move it to the
Macro Created list. If not, leave this key in the Double-click for Key Release list at this time. Repeat step 5 with your next keystroke. When you have no further keystrokes, proceed to step 7.
7. Now, double-click on the remaining commands, if any, under the Doubleclick for Key Release list in the order in which you’d like them released to move them to the Macro Created list. The Macro Created list will now show the key sequence in the exact order that it will be performed by the system. There should be no keys remaining in the Double-click for Key
Release list.
8. If you are creating a local macro, click OK to save the macro to the local computer.
- or -
If you are creating a global macro, click the Save button to save the macro to the DSAuth Server and any defined backup servers.
Chapter 4: Advanced Operations
47
The macro will now appear in the macro list and also in the macro commands on every DS/DSR appliance’s window.
Example: creating a macro where the Ctrl key is held while F1-F2-F3 are typed:
1. Enter a name for the macro. In this case, Ctrl-F1-F2-F3.
Figure 4.2: Entering the Macro Name
Ctrl keystroke under Double-click for Key Press. It will move to the second list and the command Press [Left Ctrl] will appear in the third list.
3. F1, F2 and F3 are pressed and released in order. Locate F1 in the Doubleclick for Key Press list and double-click it. It will move to the second list and the command Press [F1] will appear in the third list.
4. F1 will be released before F2 is pressed, so you will need to double-click on F1 under the Double-click for Key Release list before proceeding. This will create a Release <F1> command in the Macro Created list and F1 will disappear from the second list.
Figure 4.3: Macros Appearing in the Third List
48
DSView Installer/User Guide
5. Repeat steps 3 and 4 with F2 and F3.
6. The last step is to release the Ctrl key. Double-click on Left Ctrl in the middle list. The command Release [Left Ctrl] will appear in the third list.
Figure 4.4: The Completed Macro
7. The keystrokes will be listed in correct order in the third list. Click OK to accept the macro if you are creating a local macro, or Save if you are creating a global macro.
Macro groups
Since DSView may be used to access different computer platforms, users may find it helpful to assign distinct macro groups to global macros or local macros on individual systems.
To create a macro group:
1. From a remote session window, select Keyboard - Macro to activate the
Keyboard Macro Configuration dialog box to group local macros.
- or -
From a DSAuth window, select Options - Keyboard Macros to activate the
Keyboard Macro Configuration dialog box to group global macros.
2. The dialog box’s Macro Groups contains eight macro groups available for configuration.
To assign a macro to a group:
1. Click on the macro name.
2. In the box labeled Macro Groups, select the groups to which you’d like to have the macro assigned.
Chapter 4: Advanced Operations
49
To activate a macro group:
2. Select the macro group you wish to use.
The macros belonging to the group you selected will appear along the top of the remote session window.
NOTE: These macros will override your default selections.
Changing Cursor Settings
When using the DS Management Software, your mouse pointer will change shape when over a session window. You may change the appearance of this second pointer or eliminate it from within the DSView software.
To change cursor settings:
1. From the Node Manager, select Tools - Settings - Cursor.
2. The Program Settings dialog box will appear. You may select an alternate cursor from the drop-down menu under the Cursor heading.
3. To see what the alternate cursor will look like, move your mouse pointer over the area labeled Preview Area.
4. When you have selected a new cursor, click on the OK box at the bottom of the dialog box.
To eliminate the local mouse pointer:
From DSView, select Tools - Local Mouse - Invisible.
When this option is selected, only the target device’s mouse pointer will be visible. The local pointer may be temporarily restored by pressing Ctrl+Alt+m.
This keystroke sequence may be changed by selecting Tools - Settings - Mouse
Mode Control and entering a new sequence.
NOTE: When using a device that captures keystrokes before they reach the OS, you should avoid using the keys that restore the mouse pointer.

Adjusting Video Parameters
In some situations, DS users may wish to view several target devices at the same time on the same screen.
In most cases, you will not need to alter the Video Settings from the default.
The system will automatically adjust and use the optimal video parameters.
DSView performs best when the video parameters are set such that no (zero) video packets are transmitted for a static screen.
To automatically adjust video parameters:
You may easily adjust your video parameters by clicking on the Auto Adjust
Video button, which instructs the DS/DSR appliance to optimize the video to ideal settings.
Auto Adjust
Video
Figure 4.5: The Auto Adjust Video Button
Customizing video parameters
DS users who wish to fine tune their video performance may do so by selecting Tools - Video - Manual Adjustments in the remote session window. This displays the Video Adjustments dialog box. This dialog box will appear in one of two ways, depending on whether you are using standard video compression or the DSR DVC upgrade. See figures 4.6 and 4.7.
NOTE: The DSR DVC upgrade is standard on all newer DS/DSR appliances. Older DS/DSR appliances use standard video compression. For DSR DVC upgrade purchase information, contact
Avocent Technical Support or your Avocent reseller.
Chapter 4: Advanced Options
51
Figure 4.6: Video Adjustments Dialog Box Figure 4.7: Video Adjustments Dialog Box
(Standard Video Compression) (DSR DVC Upgrade)
Modified video settings are written to the target device. Settings are also stored per port/channel session on a system when they are made and saved so they may be used during a non-shared session as follows:
• If sharing is not enabled, the video settings made on the local DS/DSR appliance during the session are used.
• If sharing is enabled, video settings are read from the target device.
See Sharing a Device Session in Chapter 3 for more information on session sharing.
Users may verify the level of packets per second required to support a static screen by observing the packet rate which is located in the lower right-hand corner of the dialog box.
The following sections describe the effects of the video adjustments. Clicking
OK after modifying any adjustment saves the changes.
Image position
If DSView and target device mouse cursors do not align exactly when you select the Mouse - Align function, video centering may be needed using the Image
Position settings. Generally, only a few increments are required.
52
DSView Installer/User Guide
To move the screen to the right, click the Up Arrow on the Left/Right setting.
Clicking the Down Arrow moves the image to the left. Similarly, the image may be moved up and down. Moving the mouse into the remote session window will show if the correction is complete. The point (hot spot) of both DSView and the target device should be superimposed.
Image clarity
If the image in the remote session window is not clear, select Tools - Video
- Auto Adjust first. This command is also available in the Video Adjustments dialog box. In most cases, this will correct video problems. In those cases where clicking on Auto Adjust several times does not clear up a mottled screen, adjusting the contrast and brightness may help.
First increase the brightness. Do not go more that 10 increments before moving the contrast. Generally the contrast should not be moved much.
When the packet count gets close to zero, refresh the screen. If the packet count stays at zero, the video adjustment is completed.
Detection thresholds
In some cases, noise in the video transmission keeps the packets/sec count up. This may be seen when little dots change in the area of the cursor when it is moved. Varying the threshold values may result in “quieter” screens and improved cursor tracking.
Noise Threshold and Priority Threshold values may be modified if you are using standard video compression. Block Noise Threshold and Pixel Noise
Threshold values may be modified if you are using the DSR DVC upgrade.
Default threshold values can be restored by clicking Auto Adjust Video.
NOTE: The DSR DVC upgrade is standard on all newer DS/DSR appliances. Older DS/DSR appliances use standard video compression. For DSR DVC upgrade purchase information, contact
Avocent Technical Support or your Avocent reseller.
Chapter 4: Advanced Options
53
Noise Threshold and Priority Threshold (Standard Video
Compression)
The Noise Threshold and Priority Threshold values set the minimum levels in terms of changed pixels per thousand that are allowed without updating the video block. The thresholds are described below:
• Raising the Noise Threshold will usually make the packets/sec count decrease. The result will be larger cursor image artifacts remaining on the screen. Decreasing the value will make the size of these artifacts smaller.
• The Priority Threshold sets the level where a signifi cant change is noted, such as a new cursor position. Increasing the value will make the mouse movements more sluggish. The Priority Threshold setting should always be greater than the Noise Threshold setting, and usually two to three times its value. Setting these thresholds to zero will cause a constant refresh of the screen, which will make cursor tracking very diffi cult and may make it diffi cult for other network users. The goal is to reduce the packet rate to zero.
Block Noise Threshold and Pixel Noise Threshold
(DSR DVC Upgrade)
The Block Noise Threshold and Pixel Noise Threshold values set the minimum color levels in terms of changed video blocks and pixels per thousand that are allowed. See Setting the color depth in Chapter 3 for information on changing the color depth of a remote session window. The thresholds are described below:
• The Block Noise Threshold sets the minimum color change that will occur in a single video block. Increasing the value will reduce the network bandwidth. Decreasing the value will make the size of these artifacts smaller.
• The Pixel Noise Threshold sets the minimum color change in a single pixel. Decreasing the value will reduce the number of low-contrast artifacts, but will increase network bandwidth.
Image capture
The Width and Fine adjustments pertain to how the target video is captured and digitized and are seldom changed.
The Width parameter is automatically changed by the Automatic Adjustment function. A special image is required on the target in order to make accurate adjustments independently.
The Fine setting may be adjusted up or down in eight unit increments.

DSView Installer/User Guide
Video scaling
At times, a user may connect to a computer running at a higher resolution than that configured at the user’s remote system. When this occurs, the host system will be displayed in a DSView window with scroll bars. The host resolution will remain the same and users may scroll to the areas that fall outside of the frame.
If a user wishes to display the host system’s entire screen, it may be scaled to fit within the current resolution with the scaling tools.
Mouse alignment
Because DSView cannot get constant feedback from the mouse, there are times when the mouse on the DS appliance system may lose sync with the mouse on the host system. When this occurs, users may resync the mouse by clicking on the Mouse Align button. In most cases, this will correct the problem.
Mouse Align

DSView Installer/User Guide
Appendix B: TCP Ports
When the DSView Client is launched, the Node Manager will become active.
Node Manager will attempt to establish a Security Support Provider Interface
(SSPI) Messenger Class session using TCP/IP over port 2068 to the DSAuth
Server (Authentication Service). First, Node Manager will use the current NT/
2000 cached credentials to establish the session. If the cached credentials have the proper permissions, the browse list is returned from the DSAuth Server over TCP/IP port 2068. Note that the DSView Client caches this list. Using the refresh option will update the list from the DSAuth Server. If the session is refused using the cached credentials, a pop-up dialog box will prompt for the proper username and password.

After the browse list is returned to Node Manager, the user may double-click on a specific port to initiate a KVM session with that port on the DS appliance.
The DSView Client contacts the DSAuth Server, which checks the permissions on the port again. If the logged user has permissions to the port selected, the
DSAuth Server will establish a connection to the DS appliance using TCP/IP port 8191. The DSAuth Server then tells the appliance to listen to port 8192 for a DSView connection.
For debugging purposes, the details of this connection may be seen by using the console port to place the DS appliance into debug mode.

DSAdmin functions similarly to the DSView Client. It establishes a connection using TCP/IP port 2068, and uses the same process for authentication and return of the browse list. Changes made to the browse list through DSAdmin are transmitted back to the DSAuth Server using TCP/IP port 8190. After the changes are made, DSAdmin refreshes its browse list view over the TCP/IP port 2068 connection.
When the backup Authentication Service is active, it communicates with the
Primary Authentication Service via TCP port 8193. Changes to the topology are copied to and from the Primary over this port.

Appendix C: Telnet Operations
DSView ships bundled with a built-in proprietary Telnet application that provides features unavailable in many other Telnet programs. These features include configurable session properties tailored for each device, and configurable user preferences for all sessions.
Additionally, DSView Telnet offers a separate history mode to review session data, a choice of connection modes to a DS appliance, a scripting function for automatic device login and a logging function for saving session data to a file.
You may use DSView Telnet to access any DSView device that supports Telnet connections, as well as DS appliance ports.
If you do not specify a communications application for a device, DSView uses the DSView Telnet application by default. See the installer/user guide for your DS appliance for information about setting and changing the default application.
DSView Telnet screen
The title bar at the top of the screen displays the name of the device to which you are connected. If you are connected to a port on a device, the title bar displays the device name followed by the port number and port name.
The status bar at the lower left corner of the screen indicates Connected when you are operating in normal terminal emulation mode during a Telnet session.
When you are in the history mode, the status bar indicates ESC to return to
terminal mode. When you are logging, the status bar indicates Logging or Log-
ging Paused as appropriate.
The lower right corner of the status bar contains an icon that, when clicked, activates the console application, bringing it to the foreground. With this feature, you may access the console tree view without having to close the
Telnet session.
Each toolbar icon has a tooltip that appears when you rest the mouse pointer on the icon without clicking.
Security property
The Telnet security property specifies whether Telnet sessions to a DS appliance will be in Plain Text mode or SSL mode.
66
DSView Installer/User Guide
In Plain Text mode, all data is sent unencrypted to the DS appliance. When
Plain Text mode is used, any Telnet application that supports VT52, VT100,
VT100+, VT102, VT220, VT320 or ASCII terminal emulation may be used to access the DS appliance.
In SSL mode, all data sent to the device during the DSView Telnet session is
DES encrypted. The DS appliance supports anonymous Diffie-Hellman key exchange. The exchange of certificates for authentication is not supported.
When SSL mode is used, only the built-in DSView Telnet application may be used to access the DS appliance. The ports on a DS appliance have the same security property as the device.
The security property is set in DSView and in the DS appliance from the Command Line Interface (CLI). When you initiate access to a DS appliance or port via Telnet from DSView, DSView attempts to read the security property directly from the DS appliance.
If the SSL property has not been enabled on the DS appliance, and DSView receives confirmation from the DS appliance, DSView will automatically open its built-in Telnet application and you will be prompted for a DS appliance username and password.
After that information has been entered, an SSL connection to the DS appliance is established over TCP port 8192. When that connection is established, the DS appliance validates the user’s access privileges and port availability. In this case, the Telnet property screen in DSView for that DS appliance will automatically be set to SSL values, even if they previously held Plain Text mode values. The property screen will be disabled, and you will not be allowed to change any of its values. The DSView database will be updated with the information read from the DS appliance.
If DSView does not receive a reply from the DS appliance, it will use the security mode settings in the DSView database. In this case, the Telnet property screen in DSView for that DS appliance will show the database values, and you will be able to change them.
Setting the security property
The security property that is set when a DS appliance is added to the DSView database depends on the method being used to add the device.
If the Run New Device Install wizard method is used, you are prompted to select the security mode. It should match the DS appliance Server Security
Mode value that was set via the DS appliance CLI.
Appendices
67
- or -
If the Discover Configured Devices method is used, the security value that is reported by the DS appliance is used.
- or -
When the Manually Add a Device method is used, a default value of Plain Text is used.
If a discrepancy occurs between the configuration of the DS appliance and
DSView, the determining factor will be whether DSView is able to communicate with the DS appliance. If possible, the DS appliance settings will overrule any security settings in the DSView database. However, if DSView cannot communicate with the DS appliance, DSView will use the current information from its own database.
To confi gure DSView Telnet for SSL mode:
1. In the DSView tree view, select a DS appliance.
4. The Properties dialog box appears. If the SSL security mode has been set on the DS appliance, and DSView successfully accesses that device, the DSView Telnet properties are automatically updated with SSL mode information, and then disabled.

3. Enable or disable the Strip 8th Bit checkbox. The default value is disabled.
Login scripts
The DSView Telnet application has a login scripting function that enables you to automatically log in to a device. A login script is built with a sequence of expect and send strings, and initial transmission characters that work with them. To use a login script, you must enable automatic login in a checkbox.
The first Initial character (that is, the first entry in the Initial character column) specifies what is sent to the device as soon as the Telnet session is established. This is selected from a list containing the choices: None, CR
(carriage return), CR+LF (carriage return and linefeed), ESC (Escape) and
CTRL+P (Control and P).
The first Expect string indicates what the device will send as its first prompt.
The first Send string indicates what the login script will send to the device after it receives the first Expect string.
You may then build additional Expect and Send strings according to what the particular device will prompt for and what will be sent in response.
To build a login script and enable/disable automatic login:
1. Select Options - Session Properties from the menu bar.
- or -
Click the Session Settings icon in the toolbar.

Macros
The DSView Telnet application has a macro function that allows you to create and use macros during Telnet sessions. A macro comprises a series of keystrokes that you define. Additionally, you may specify a hotkey in the macro’s definition. When you define a macro and enable its inclusion in the Macros
76
DSView Installer/User Guide menu, you may execute the macro during a Telnet session either by selecting it from the Macros menu or by pressing the defined hotkey on your keyboard.
You may also define one or more macro groups, then add macros to the groups. A macro may belong to more than one macro group; however, a macro does not have to belong to a macro group. The Session Properties -
Terminal screen contains a list of defined macro groups from which you may select one group or all defined groups. The macros in the selected group(s) are then available for use during subsequent Telnet sessions with that device/port.
After defining a macro or a macro group, you may edit or delete it at any time.
When you delete a macro or macro group, you are prompted for confirmation.
When you change a macro group name, each macro belonging to the changed macro group is updated, but the change is not visible until the next Telnet session is established. When you delete a macro group, you delete only its name - the individual macros in the group are not affected.
To create a macro:
1. Select Macros - Configure from the menu bar. The Macros dialog box appears.
3. Type a 1-32 character name in the Name field.
4. To define a hotkey for the macro, choose one from the Key list. To add a modifier to the hotkey, check the Control, Shift or Alt boxes.
5. By default, the Include in Macro Menu box is checked, indicating the macro will appear in the Macros menu. If you do not wish to include the macro in the Macros menu, uncheck this box. In this case, if the macro definition includes a hotkey, you will still be able to use the hotkey to run the macro, even if the macro’s name does not appear in the Macros menu.
6. Type the macro string in the Enter Keystrokes box. For non-printing and special character code sequences, use the following escape sequences:
Carriage return: \n
Tab: \t
Hexadecimal code sequence: \Øx<NN>, where <NN> is the hexadecimal byte Delay character (500 ms): \d

Logging
The DSView Telnet application has a logging function that saves the contents of a Telnet session to a file. You may enable automatic logging or dynamically start logging at any time. Additionally, you may pause, resume and stop logging, regardless of whether it was started automatically or dynamically.
While logging is occurring or when it is paused, a Logging Status label appears in the status panel at the bottom of the DSView Telnet window.
NOTE: When you enable or disable automatic logging, the logging will begin or end at the start of the next DSView Telnet session to that device. If you change the default log fi le directory used for automatic logging, the change does not take effect until the next session to that device.

The format of log filenames is shown below, where <mmddyy> represents the month, day and year, and <hhmmss> represents the current hour, minute and second in military time:
avtelnet<mmddyy>_<hhmmss>.log

The default log directory is session-specific, that is, each Telnet session may have its own location for storing logfiles. You may change the name of the file and the location of the directory that stores the logfiles. If you do not change the default directory, logfiles are stored in your home directory.
You may view a log file at any time, using a standard text editor. The screen buffer is written to the log file when the buffer is full, or when logging is paused or stopped. To ensure the log file is up-to-date, either pause or stop the logging.
To change the default log fi le directory:
1. Select Options - Session Properties from the menu bar.

DSView Installer/User Guide
Appendix E: Setting SNMP Traps (Windows NT/
2000/XP Only)
An SNMP (Simple Network Management Protocol) trap is a notification sent by a
DS appliance to a host system indicating that an event has occurred in the DS appliance that may require further attention.
SNMP is a protocol used to communicate management information between network management applications and DS appliances using TCP/IP and IPX protocols. Other SNMP managers (such as Tivoli and HP OpenView) may communicate with your DS appliance by accessing MIB-II (Management Information Base) and the public portion of the enterprise MIB. MIB-II is a standard MIB that many
SNMP target devices support. When you access a DS appliance for the first time,
DSAuth will retrieve the SNMP parameters from the DS appliance.
DS appliances are defined on the host by criteria such as system information, which stations may manage the DS appliance, which stations may receive
SNMP traps from the switch and the community to which they belong. If you select Options - System Settings from the DSAuth window and then check Enable
SNMP trap log in the System Settings dialog box, the appliance will log SNMP received messages over UDP (User Datagram Protocol) port 162.
The traps must be configured on each DS appliance using the CLI interface.
The address of the server running DSAuth must be configured as a trap recipient, the proper community must be set, and each desired trap must be enabled.
To use SNMP trap logging:
1. Install and confi gure TCP/IP on the DSAuth Server.
2. Install the SNMP service on the DSAuth Server, confi gure the host as trap recipient and enable the traps.
3. Enable the SNMP service on the DSAuth Server.
Appendices

Appendix F: Menus and Commands
Pulldown menus
The DSAuth, DSView Client and remote session windows each contain a number of commands that may be accessed using the pulldown menus located along the top of the windows.
Shortcut menus and commands
You may access shortcut menus within the DSAdmin and DSView Client windows by selecting a DS appliance, target device or port and right-clicking to display a shortcut menu.
DSAdmin Shortcut menus and commands
In the DS topology view, you may right-click on any DS appliance’s name or IP address in the DSAdmin window to display a shortcut menu containing six commands:
• Collapse - Clicking on this command will hide the port information associated with the selected name or IP address.
• Expand - Clicking on this command will display the port information associated with the selected name or IP address.
• Properties
• Rename
• Delete
• Permissions
• Reboot
In the DS topology view, you may right-click on any port to display a shortcut menu containing four commands:
• Properties
• Rename
• Permissions
• Disconnect
98
DSView Installer/User Guide
DSView Client shortcut menus and commands
In the DS topology view, you may right-click on any DS appliance’s name or IP address in the DSView Client window to display a shortcut menu containing three commands:
• Reboot
• Collapse
• Expand
In the DS topology view, you may right-click on any port to display a shortcut menu containing three commands:
• Connect
• Privacy Mode Connect
• View Connected Users
Telnet window menus and commands
Serial DS appliances and target devices are operated through a Telnet window. When you are operating a DS appliance or target device using the
DS/DSR appliance, you will be provided with several optional commands.
Telnet menu
Exit
This command will exit the Telnet Client and return users to the DSView
Client menu. If the option to Prompt on Exit (see the Preferences section of this appendix) is enabled and a connection is active, the DS user will be prompted to confirm the exit. If no connection is active, the Client will exit without a prompt.
View menu
History
When this menu option is checked, the DS user will be switched to history mode. Here the DS user may scroll through a history of the Telnet session up to the current point. While the DS user is in history mode, all new data is buffered and may be viewed by scrolling to the end of the history. DS users may exit history mode at any time by pressing the Esc key.
Go to Beginning
