Chapter 1: General Information Overview of TimeVault

1.2 Overview of TimeVault

TimeVault is a high-performance, internet-enabled Network Time Protocol (NTP) server that operates in a secure access environment and provides time to multiple clients with extreme accuracy. To provide trusted time and guard against any denial of service, TimeVault uses GPS as a primary synchronization source, backed up by ACTS and NTP as secondary and tertiary sources, respectively.

TimeVault provides network time synchronization over Ethernet connected networks via Network Time Protocol (NTP), developed by Dr. David Mills at the University of Delaware. TimeVault currently supports versions 2 and higher of the NTP, RFC-1305, as well as the Simple Network Time Protocol (SNTP), RFC-2030. In addition, TimeVault responds to TIME protocol requests, RFC-868. For details about these protocols, refer to Appendix A and Appendix B in this manual.

The main feature of TimeVault’s web interface is its ability to perform setup and control operations from a remote location, using the Internet or TCP/IP LAN (see Chapter 3).

1.10 Internal Timing Performance Specifications

The timing accuracy achievable with this product depends on several factors. The most important is the method TimeVault employs to use the NTP information. It is widely accepted that the uncertainty of any single NTP packet is on the order of 10 ms. However, most NTP client programs perform averaging and filtering over several NTP transfers, improving the accuracy and removing the systematic delays. The performance of the various NTP clients varies widely, but some are able to achieve accuracies below 1 ms.

Inherent accuracy:

• With GPS synchronization, approximately 125 µs (this accuracy exceeds that which

the NTP protocol delivers over a network)

• With ACTS synchronization, 5 ms. In this case, the system accuracy is limited to the accuracy of the ACTS input.

• With NTP client mode synchronization, the accuracy of the client software is the limiting factor in determining the delivered time accuracy.

• Accuracy of packet delivery time to network jack: <0.5 ms

Network timing accuracy is limited to 1-10 ms typical.

During a synchronization input outage, following initial synchronization of TimeVault to its input synchronization sources, the time maintained in the unit diverges from the input at the rate of approximately 6 parts in 10-6, if the ambient temperature is maintained within ± 3 °C.

Chapter 1: General Information Network Time Protocol Synchronization Specifications

1.11 Network Time Protocol Synchronization Specifications

TimeVault’s hardware is specifically designed to implement the NTP server function. As such, it was carefully designed to minimize the unknown latencies in timestamping received and transmitted NTP packets. The NTP timestamp accuracy specifications are:

Received Timestamp Accuracy: <0.1 ms, relative to synchronization source

Transmitted Timestamp Accuracy: <0.1 ms, relative to synchronization source

At these levels, the realizable NTP synchronization accuracy of any host is determined by the repeatability of network and client delays, not by TimeVault’s timestamp uncertainty.

2.1 Site Preparation

2.1.1 Mounting Instructions

To securely mount TimeVault in any EIA standard 19-inch (48.26-cm) rack system, use the equipment supplied in Symmetricom’s Rack Mount Kit and follow the steps outlined below.

The Rack Mount Kit contains:

• 2 mounting brackets (part number 206-719)

• 4 flat-head, Phillips screws (part number 241-008-005, 8-32 x 5/8)

To rack mount TimeVault:

Installation and Start-Up

1. Remove and discard the two factory-installed flat head (Phillips) screws from the front end of a TimeVault side panel.

2. Place a rack mount bracket on the side panel, so that the countersunk screw holes in the bracket line up with the screw holes in the panel.

3. Place 2 flat-head Phillips screws from the Rack Mount Kit through the holes in the bracket and into TimeVault.

Replace the factory-installed screws with screws from the Rack Mount Kit

4. Tighten the screws to the following specifications: Use a #2 size Phillips bit with an inch ounce torque setting of 4 ¼ to 4 ¾ (high).

5. Repeat steps 1-4 to install the other rack mount bracket on the unit’s other side panel.

6000-100Ch2.fm Rev. D TimeVault™ User’s Manual 2-11

Chapter 2: Installation and Start-Up Site Preparation

6. Place TimeVault in a 1 ¾ in (4.445 cm) opening in any EIA Standard 19-in rack system, and position the unit so that the rack holes line up with the holes in the bracket.

7. Use the appropriate screws to secure the brackets to the rack.

8. Ensure that the operating ambient temperature does not exceed +50 °C.

Installation requires the use of standard rack mount hardware.

2.1.2 Necessary Equipment

The equipment you need to get started includes:

• Power source

• GPS antenna connection that supports 12 V

• An Ethernet LAN with one port available for TimeVault’s network connection

• An Ethernet cable with an RJ-45 connector for the NET Port (Category 5 Ethernet

cable is recommended for 100Base-T operation)

• A separate analog phone line for the ACTS modem

• A cable with an RJ-11connector for the ACTS Port

• A set of network address parameters for the NET Port that delivers NTP time and

allows remote control of the unit over the Internet

TimeVault requires a 12 V antenna and may severely damage any antenna that does not support

12 V. For non-standard antenna types, contact Symmetricom for assistance.

Optionally, you can add an RS-232 serial interface for local control using a terminal emulation program. This requires:

• A serial interface device, either PC or dumb terminal capable of 9600 8N1

• An RS-232 cable, and null modem connector, to connect the 9-pin D RS-232 port to

the serial device

TimeVault is capable of basic operation without an RS-232 connection, and retains all configuration data in memory.

2.1.3 Antenna Information

Voltage Requirement and Signal Levels

12 V GPS Antenna

TimeVault requires a 12 V antenna. Any antenna that does not support 12 V may be severely damaged if plugged into TimeVault.

Coaxial Cable

The GPS Synchronized Receiver, integral to TimeVault, operates on the L1 (1575.42 MHz) signal and the C/A

code (1.023 MHz bit rate) with a minimum signal level of –162.0 dBW and a maximum signal level of –137.0 dBW. The antenna system supplied is designed to provide the proper signal levels to the receiver with the cable length supplied.

Figure 2-1 Basic Antenna

Use of a Splitter

Components

To run multiple units with a single 12 V antenna, use a splitter. Do not use a BNC “T” connector, which doesn’t provide the proper voltage the unit needs to operate.

Lead-In Cable

The L1 GPS antenna is designed to operate with up to 200 ft (60.96 m) of RG-59 coax cable. The optional Down/Up Converter is designed to operate with up to 1,500 ft (457.2 m) of RG-58 coaxial cable. For details and illustrations on cabling, see page 2-15.

2.1.4 GPS Roof-Mounted Antenna Installation

When selecting a site for the standard outdoor antenna, find an outdoor location that provides full 360-degree visibility of the horizon. In most cases, this means locating the antenna as high as possible. Any obstruction will degrade unit performance by blocking the satellite signal or causing a reflection that cancels some of the signal. Blocked signals can significantly increase the time for satellite acquisition, or prevent acquisition all together.

Mast Mounting

Mast top mounting is the preferred mounting method and special brackets are provided to mount the antenna to a pipe or the peak of a building. The antenna mounting mast should be 2-inch (5.08-cm) water pipe or conduit. The mast must be rigid and able to withstand high winds without flexing. Guy wires may be used to stabilize a mast longer than 10 ft (3.048 m)

Multipath cancellation is caused by reflected signals that arrive at the antenna out of phase with the direct signal. Reflective interference is most pronounced at low elevation angles from 10 to 20 degrees above the horizon. You may

extend mast height to prevent multipath cancellation. The antenna should be at least 3.28 ft (1.0 m) from a reflecting surface. The figure at the right shows the recommended mounting of the antenna to the mast.

2.1.5 GPS Window-Mounted Antenna (140-619) Installation

The GPS Window-Mounted Antenna is intended for use with products featuring ‘single satellite timing,’ (available with firmware version 8 and above). Customers with units running earlier firmware versions should upgrade to the current version. Information on upgrading is available at

www.truetime.net/downloads.html.

Window mounted antennas have a restricted view of the sky, yielding intermittent satellite coverage. With single satellite timing, a network time server can synchronize with individual GPS satellites as they pass through the antenna’s field of view.

Placing the Window Antenna

Select the window with the best unobstructed view of the sky. For equivalent views, select the window with the best orientation. The orientations, in order of preference, are as follows:

1. Equator-facing (e.g., South, for users in the Northern hemisphere.)

2. East/West-facing

3. Polar-facing (e.g., North, for users in the Northern hemisphere.)

Note: Regardless of orientation, use the window with the best view of the sky.

Mount the antenna on the lower part of the window, where it has the best upward visibility, by pressing the suction cup onto the window. Make sure the window and suction cup surfaces are clean. Note that some windows have metallic glazing that blocks GPS signals: this prevents GPS receivers from tracking satellites and determining the time.

Power-Up Chapter 2: Installation and Start-Up

2.3 Power-Up

At power-up (cold boot), the front-panel display is blank.

After about 10-12 seconds, the display reads:

TimeVault Booting...

After another 10 seconds, the display reads:

TimeVault Loading...

System software initialization takes about 18 seconds, after which the display reads:

Software Load Successful

Display initialization takes another 12 seconds, after which all synchronization modes – GPS, ACTS, and NTP – simultaneously attempt to acquire and lock to their respective sources. When display initialization is complete, you can enter data through TimeVault’s front panel keypad or serial/Telnet interface. Once TimeVault has synchronized itself, then it is ready to respond to time requests it receives over the network through supported protocols.

To avoid unnecessary long distance charges, TimeVault will not call out to ACTS if a higher

priority synchronization source is operational.

2.3.1 GPS Mode

Consider the GPS mode operational once TimeVault tracks at least four satellites and receives ephemeris, ionospheric, and leap seconds data from each. The process of satellite acquisition is described below.

Once TimeVault starts searching for GPS satellites, the display reads:

Satellite acquisition may take up to 20 minutes. Display messages indicate the sequence, such as:

Searching for Satellites

Tracked = 1

6000-100Ch2.fm Rev. D TimeVault™ User’s Manual 2-17

Chapter 2: Installation and Start-Up Power-Up

Satellite Acquisition

Satellite acquisition begins at power-up and continues until power-down. The length of satellite acquisition time depends on many factors, some of which are described below.

When TimeVault performs initial acquisition of GPS satellite data, it ‘listens’ for all available GPS signals. After three satellites are acquired, the receiver locks onto GPS as a reference source, and delivers UTC time. This procedure takes from 3 to 20 minutes, depending upon current satellite visibility. Longer aquisition times may be needed for window mounted GPS antennas that have very poor visibility.

After initial acquisition, and the TimeVault has saved its current average position, and recent ephemeris/almanac information, it can typically lock to GPS as a reference source in 3 to 5 minutes. The TimeVault needs an intermittent fix on three satellelites several times per day in order to maintain current position/ephemeris/almanac information. Provided with current position/ephemeris/almanac information, the TimeVault can maintain GPS as its reference source by tracking only one satellite. If the number of GPS satellites being tracked drops to zero, the unit remains locked GPS as a reference source for approximately 5 minutes while it attempts to re-acquire another GPS satellite. Because the TimeVault is optimized for time functionality, accurate position readouts are not available.

If the current position is unknown or in error by more than 1 km (0.62 miles), acquisition typically requires from 3 to 20 additional minutes to locate current antenna position, reacquire satellite almanac and ephemeris data, and deliver UTC time.

Window Antenna Satellite Tracking

Firmware version 8 and above enable the TimeVault to operate with window-mounted GPS antennas. Because window mounted antennas have a restricted view of the sky; they receive fewer GPS satellite signals than roof mounted antennas. In some situations, a window-mounted antenna may provide only one intermittent GPS signal to lock onto as individual GPS satellites pass through its field of view. Firmware version 8 enables network time servers to use GPS as a reference source when intermittent GPS satellite signals are available.

Table B.1: Summary of Firmware Version 8 Improvements

Version 7 and earlier Version 8 and after

Requires continuous lock on four satellite signals to maintain GPS as the reference source.

Requires intermittent fix from three satellite signals (several times a day). Will hold lock on one satellite signal to maintain GPS as the reference source.

Operates with roof mounted antennas. Operates with window and roof mounted

antennas.

Power-Up Chapter 2: Installation and Start-Up

Table B.1: Summary of Firmware Version 8 Improvements

Version 7 and earlier Version 8 and after

If the number of current satellite signals drops to 1 or 2, the unit uses GPS as reference source for 10 minutes.

2.3.2 ACTS Mode

Consider the ACTS mode operational once TimeVault has successfully dialed out to the ACTS service and received time (see Appendix E for details).

TimeVault only enters ACTS mode if GPS is not operational.

2.3.3 NTP Mode

TimeVault’s NTP subsystem can be either a server to downstream clocks in the system, or a client to another NTP server. After display initialization, TimeVault begins requesting time through NTP from a user-defined server list. TimeVault polls each server in turn until it receives a valid NTP response. Consider the NTP client mode operational once TimeVault receives six valid NTP responses from at least one NTP server from the list. This may take 8-10 minutes.

If the number of satellite signals drops to zero, the unit keeps GPS as the reference source for 5 minutes while it locks onto another GPS satellite signal.

TimeVault only enters NTP mode if both GPS and ACTS are not operational.

2.3.5 Rolling Redundancy

Rolling redundancy ensures secure, uninterrupted time delivery.

During normal operation, TimeVault receives the time through GPS, its designated primary synchronization source. If GPS loses time synchronization, there is a brief holdover period before TimeVault’s modem calls ACTS, the designated secondary synchronization source.

During this period, TimeVault uses its internal oscillator to deliver precise time. If, after three minutes, GPS is still not synchronized, ACTS takes over and provides the time until GPS is once more available. At this point, TimeVault rolls back over to GPS.

If both GPS and ACTS were to fail, TimeVault rolls over to NTP, its designated tertiary synchronization source. TimeVault uses NTP until either GPS or ACTS is once again available.

This rolling redundancy sequence is summarized in the following illustration:

Primary Good

Start-Up

Tertiary Good

Primary Bad

Secondary Good

Secondary Bad

GPS

ACTS

Primary Good

NTP

Although TimeVault is not designed to resist a denial of service attack from a hostile source, an excessive number of NTP requests in a short period of time will not cause the system to crash or lock up.

Keypad Entry Guidelines

The following general guidelines apply to keypad function entry. Read these before configuring TimeVault for the first time:

• At power-up, do not use the keypad for data entry until you see the message

Searching for Satellites... on the front panel display. TimeVault ignores

any data entry attempts prior to this.

• When entering parameter values, position the horizontal cursor under the digit you

want to change using the ← and → directional push-buttons. Use the ↑ and ↓ push-buttons to increase or decrease the value.

• When entering function settings (DHCP and Remote Control), the directional

push-buttons act like toggle switches.

• Press SAVE to store any entries you make and proceed to the next screen.

Unless you press SAVE after entering data, your entries will be lost.

• Press SET-UP to proceed to the next screen without storing changes.

• If you have made and stored any parameter changes, TimeVault resets after you

press SET-UP the last time (after the Remote Control display).

• Once Display Security (password protection) is enabled, you must enter your user

ID and password before using the display to review or modify parameter values.

7. Display Security Logout. An example of the display is:

Display Security Logout

Whenever you save changes to any network parameter in this sequence, TimeVault automatically reboots (this does not include the DHCP, Remote Control, and Display Security functions).

The Remote Control feature determines the availability of remote access to TimeVault. The default setting is “Unlocked”, which allows use of the Telnet or web interface for set-up and control operations (see Chapter 3 for how to set up Telnet, and Chapter 4 for how to issue F-series function commands). You can lock TimeVault from a remote location using the F100 LOCK command, but after having done so, you can not remotely unlock it. You can only unlock TimeVault from the keypad. For more information, see “Keypad Entry Guidelines” above, and Section 4.4.13 “F100 LOCK – Remote Lockout” on page 4-76.

Entering the User ID and Password

You cannot change the ID and password via the keypad, only via F100 commands.

The Display Security feature prevents unauthorized users from setting or modifying TimeVault parameters. When you first receive the unit, the security setting is off (factory default).

To view the current security setting, scroll through the parameter list using the SET-UP push-button until Display Security appears. To enable Display Security, press any directional push-button. The security setting changes from “OFF” to “ON”. You can now enter your user ID and password, as per the procedure described below.

Once you enable the Display Security feature, it remains “ON” until you manually disable it.

Enter user IDs and passwords with the front panel directional push-buttons, as follows:

• Press the ↑ directional push-button to start at the letter “i” and move backwards

through the alphabet, symbols and numbers.

• Press the ↓ directional push-button to start at the letter “r” and move forward

through the alphabet, symbols and numbers.

• Press the ← or → directional push-buttons to reposition the cursor. During

password entry, pressing the → directional push-button not only advances the cursor position, but also changes the previously entered character to a “*”. If you make an incorrect entry, reposition the cursor and re-enter the character.

To enter the user ID and password, follow these steps:

1. Press the SET-UP push-button until ID:/Password: appears, with the cursor posi- tioned on the ID: line (the SET-UP push-button toggles cursor position between the two lines).

2-26 TimeVault™ User’s Manual 6000-100Ch2.fm Rev. D

Front Panel Interface Chapter 2: Installation and Start-Up

2. Enter a character with either the ↑ or ↓ arrow, as described above.

3. Press the → directional push-button to advance the cursor.

4. Repeat step 2 and step 3 until you have entered all the user ID characters.

5. Press the SET-UP push-button to reposition the cursor on the PW: line.

6. Enter password characters using step 2 and step 3 above.

Every time you press the → directional push-button, the previous character becomes a “*”.

7. After entering the last password character, press the → arrow once more, so that all

characters are “*”s.

8. Press the SAVE push-button to save all entries and enter the parameter display sequence.

If you followed this procedure correctly, the first parameter (IP Address) appears and you can now enter initial system parameters as per the procedure in Section 2.5 on page 2-28. If there was a problem with security set-up, a message appears: “Invalid Login ID or Password.”

Once you have set the user ID and password, you must enter them whenever using the front panel alphanumeric display to review or modify system parameters. For a quick review, or to modify parameters remotely, use the TimeVault web interface or a serial connection.

Further Precautions

After 10 minutes without any front panel push-button activity, TimeVault automatically times out the security feature. You must re-enter user ID and password to review or modify system parameters through the front panel alphanumeric display.

However, under circumstances when you must protect TimeVault before the 10-minute time out, you can do this manually with the Display Security Logout feature.

To manually logout of Display Security:

1. Press the SET-UP push-button to scroll through the parameter list until Display Security Logout appears.

2. Press the SAVE push-button. The default UTC time and date display appears.

After logging out, you must re-enter the user ID and password to review or modify system parameters through the front panel alphanumeric display.

Disabling Security

The Display Security feature remains “ON” until you manually disable it. To disable the Display Security feature:

1. Press the SET-UP push-button until Display Security appears.

2. Press any directional push-button to change the security setting from “ON” to “OFF”.

3. Press the SAVE push-button. The default UTC time and date display appears, and system parameters can now be reviewed or modified by anyone.

2.5 NET Port Network Parameters: First Time Configuration

After connecting the GPS antenna, supplying power to TimeVault, and achieving successful stabilization, stop cabling and configure the network parameters and functions for the first time. Then connect the Ethernet cable and, optionally, the serial cable. Observing this order of events ensures that the IP Address is correct and sets operating speed at 10Base-T.

To change the maximum operating speed to negotiate between 10/100Base-T on networks that support the higher speed, see Step 9 below.

The configurable NET Port network parameters and functions are:

• Display Security

• IP Address

• Subnet Mask

• Default Gateway

• DHCP

• Remote Control

Upon arrival, TimeVault’s Display Security feature is off (factory default), and you can set parameters according to the procedure below, without entering or using a user ID or password. If you wish to secure the front panel display first, follow the steps on page 2-26 in the section “Entering the User ID and Password”.

For the first configuration, enter the appropriate parameter values and function settings through the front panel keypad. Optionally, you could use the serial port (referred to in this manual as the “Utility Port”) through a serial device connected at 9600 8N1. Subsequently, you can edit parameter values and function settings through the keypad, the web interface, the Utility Port, or using Telnet (see Section 4.4 “Extended Function Commands” on page 4-59).

To set the NET Port network parameter values and function settings for the first time:

1. Press the SET-UP push-button to display the IP Address.

2. Position the cursor under the digit you want to change using the ← and → buttons.

3. Increase or decrease the value with the ↑ or ↓ buttons.

4. Press the SAVE push-button to store the new values and proceed to the next screen. If you do not press SAVE, your entry will be lost.

5. Use Steps 2 – 4 above to set and store a new Subnet Mask value.

6. Use Steps 2 – 4 above to set and store a new Default Gateway value.

7. Review the current DHCP function setting, then use Steps 3 – 4 above to set and store a new DHCP setting, if appropriate (see “DHCP Configuration” before changing this setting). The directional push-buttons toggle between setting options.

8. Review the current Remote Control function setting, then use Steps 3 – 4 above to set and store a new setting. The directional push-buttons toggle between setting options.

DHCP Configuration Chapter 2: Installation and Start-Up

9. End the configuration sequence by pressing SAVE. TimeVault automatically resets if you have saved any changes to any network parameter (excluding Remote Control), and sets the operating speed at 10Base-T. Go to the section “Verify Functionality” to verify the operation of the TimeVault.

2.6 DHCP Configuration

The easiest way to configure the network parameters is via Dynamic Host Configuration Protocol (DHCP). If your network has a DHCP server installed (check with your system administrator), you can use this service to set up your TimeVault. The TimeVault is shipped with DHCP turned off. To enable DHCP, use the following procedure:

1. Press the SETUP button several times until the message DHCP status OFF is displayed.

2. Use the ↑ and ↓ buttons to turn DHCP on.

3. Press the SAVE button to store the new setting.

4. Press SAVE again to scroll through the remaining messages.

5. The TimeVault will then reset itself. During the boot process, it will request network settings from the DHCP server, and then will be available on the network.

6. Press the SETUP button to find the assigned IP address. Then go to the section “Verify Functionality” to verify the operation of the TimeVault.

2.7 Verify Functionality

To verify that the unit is running:

1. Ping the NET Port IP Address.

2. If this action fails, check the configuration values assigned to the NET Port. Correct parameters as necessary using the front panel keypad, described above, or the serial/Telnet Function F100 IC command, described on page 4-64.

3. If ping fails again, verify with your system administrator that the values used are correct. Then re-enter parameters as necessary.

2.8 Wrap-Up & Advanced Operation

When the LAN interfaces are operational and time is being reported, the unit has achieved its basic level of functionality. For “quick start” information, see the Quick Start card that came packaged with this manual. For remote operation, see Chapter 3. For details on serial/Telnet commands, see Chapter 4.

If you wish to configure NTP client mode, or to use SNMP (TimeVault supports a SNMP version 1 agent with the MIB II and Enterprise MIB databases), you must first edit the ntp.conf and snmp.conf files (see Section 4.4.12 “F100 CONFIG – FTP Configuration of NTP, SNMP & ACTS Parameters” on page 4-67 for details).

2-30 TimeVault™ User’s Manual 6000-100Ch2.fm Rev. D

Remote Operation

Symmetricom’s TimeVault is an advanced time server that provides trusted, accurate time from multiple time sources over an Ethernet connection to multiple client sites. One of TimeVault’s great strengths is its remote control capability. You can configure parameters through command line input using Telnet from a distant terminal, or use TimeVault’s web interface to program the unit over the Internet, from anywhere in the world.

You do not need a web connection for normal TimeVault operation.

TimeVault reports time with extreme accuracy, using GPS as a synchronization source. Optimization for time functionality means that accurate position readouts are not available.

3.1 Web Access

The main feature of TimeVault’s web interface is its ability to perform setup and control operations from a remote location, using the Internet or TCP/IP LAN. The protocol used is either Telnet or HTTP. Telnet is a standard Internet communications program that is bundled with Windows 95/98/NT and connects to TimeVault through its NET Port. HTTP access is provided via any standard Web Browser (such as Microsoft’s Internet Explorer or Netscape’s Navigator/Communicator).

You can also disable remote control capability and secure TimeVault from a remote location, (see “F100 LOCK – Remote Lockout” on page 4-76). However, once you have issued this command, you can not remotely unlock the unit. You can only unlock the unit from the keypad.

3.1.1 Starting the Web Browser

To use the web interface, launch any Java-capable and frames-compatible web browser such as Microsoft Internet Explorer (IE version 3.0 or later, available at www.microsoft.com), Netscape Navigator (version 3.0 or later) or Netscape Communicator (any version; Netscape browsers are available at www.netscape.com)

3.1.2 Accessing TimeVault’s Web Pages

In the Location field (Netscape), the Address: field (IE), or the equivalent field in the window of a different web browser, enter the IP address assigned to TimeVault’s NET Port in the following format:

http://<ipaddress>

An example of an TimeVault’s NET Port IP address is:

http://192.168.1.1

After entering the NET Port IP address, Symmetricom’s home page appears in the browser window. The Home page, which always displays UTC time and date, as well as the current clock source, is your access to all the other web pages. For future quick access, you can bookmark the Home page (in Netscape), or add it to your browser favorites (in IE). Use the buttons that always appear in the left portion of the Symmetricom web interface window to navigate from page to page.

The following list shows all the available web pages and how to find them. An indentation means you get to that particular page from the page just above it. For example, you reach the Satellite Status page from the GPS Status page:

• Home (links to...)

•Time Status (click Time)

• GPS Status (click GPS; links to...)

• Satellite Status

• ACTS Status (click ACTS)

• Network Status (click Network)

All values displayed on these pages are static, that is, they do not reflect changes that occurred following the initial display of the page. For example, the current clock source and UTC time and date, which always appear on the Home and Time Status pages, are frozen at the instant the web page first displayed and do not automatically update. For the most recent values, click Reload or Refresh on the tool bar at the top of your web browser, or right click the area around the parameter display and select Reload Frame or Refresh from the menu that appears.

3.1.3 Configuration Control Login Page

Accessed from the Home page (click Controls), the Configuration Control Login page is your gateway to remote query and configuration of TimeVault. After successfully logging in, when you display this page, or any of the control pages, navigation buttons for all control pages appear at the left of the window.

Any change you make on a control page causes TimeVault to reset.

After any reset, do not submit further parameter changes until the unit fully reinitializes, that

is, until you see the correct time and date on the front panel display.

To log in, enter the user name operator (you will not be able to edit parameters if you log in any other way) and the default password mercury in the corresponding fields on this page, then click Press to Continue, located just below the password box. The page instantly refreshes. Look in the Status Message Window for the “Login passed.” message to see whether or not the login was successful (you may have to scroll down to see it). If the Status Message Window shows that login failed, re-enter the user name and default password and click Press to Continue again.

As with all password protection, to ensure security, please change the default password as soon

as possible using the “F100 P” command (see page 4-64). Password changes can only be made using the serial or Telnet interface. Maximum password size is 10 characters.

Status Message Window

Regularly check the Status Message Window. If, for example, a processing error or transient network problem causes one or more of your entries to fail, a notification message appears here. If this happens, simply resubmit the entry. If you encounter repeated failures, use the Telnet or serial interface to make those entries.

Chapter 3: Remote Operation Telnet Access

3.2 Telnet Access

TimeVault can perform setup and control operations sent from a remote location through the Internet. The protocol used for Internet access to TimeVault is Telnet, a standard Internet communications program, with an ASCII character-based interface, that is bundled with Windows 95/98/NT and connects to TimeVault’s NET Port. Use Telnet just like Procomm, or any other serial interface program, by entering F-series commands, to which TimeVault responds.

The Utility Port takes precedence over the Telnet session. If the Utility Port is active, either Telnet login will fail or, if already logged in, trying to send any Telnet command generates the response:

NOTICE: Cannot respond to command because Utility Port session has priority.

Telnet sessions have a 15 minute session timer. If there is no activity on the Telnet session, the timer automatically terminates the session.

3.2.1 Starting Telnet and Making a Connection

The following section only applies to Microsoft Windows users. If you are using an operating

system other than Windows (such as Macintosh or UNIX), check with your System Administrator for Telnet application information.

1. Press Start on the task bar in the lower left corner of your screen.

2. Click Run and enter Telnet in the Open field. The Run dialog box appears:

3. Click OK. The Telnet – (None) window appears:

8. Enter the default password truetime (one word, all lower case). A welcome message appears if the login and password are approved:

9. Begin your Telnet session by entering F-series commands.

3.2.2 Ending Telnet

There are three ways to end Telnet:

• Close it from your terminal by selecting Exit from the Connect menu.

• Enter an exit command, such as

exit, or quit.

• Let it timeout. If no commands are received for 15 minutes, TimeVault

automatically terminates the session.

Chapter 3: Remote Operation Serial Access

3.3 Serial Access

The RS-232 connector provides serial access. The RS-232 connector is located between the NET Port and the front panel display (see Figure 1-1 on page 1-7). This connector is labeled “Serial I/O”, and is referred to as the “Utility Port.” Table 3-1 below describes the Utility Port’s RS-232 pinouts and signal levels.

Serial time output is not available on the Utility Port.

The Utility Port can be connected either to a terminal or to a computer, using a null modem cable, and used in conjunction with any serial access (terminal emulation) software program, such as Procomm or HyperTerminal. The following section illustrates a terminal connection, using HyperTerminal, a popular Windows-based application. All commands are input using conventional F-series type commands (see “Command List” on page 4-51).

These examples apply only to systems using Windows 95/98/NT. Check with your System

Administrator if you are using a different operating system (such as Macintosh or UNIX).

Chapter 3: Remote Operation Session Timers

3.4 Session Timers

There are timers on Utility Port, Telnet, and web control sessions that terminate them if there is a lack of activity. Any action you take during a session automatically resets the timer, and it starts all over again. The timers and their interactions are described below.

3.4.1 Utility Port Session Timer

The Utility Port Session Timer starts upon receipt of a character from the Utility Port. The timer is reset upon receipt of every character. If no characters are received for 15 consecutive minutes, the session terminates.

When a Utility Port Session is in progress, Telnet cannot execute any commands to TimeVault. The Utility Port Session must end before full Telnet access is possible.

3.4.2 Telnet Session Timer

The Telnet Session Timer starts upon receipt of a command line from Telnet, via the NET Port. The timer is reset upon receipt of every command line. If no lines are received for 15 consecutive minutes, the session terminates.

Terminating a Telnet session drops the connection to the remote host. You can immediately activate a new session by re-connecting and logging in again.

3.4.3 Web Control Session Timer

Once you are logged in to any Control Page, you can send HTTP requests from a web browser, via the NET Port. The Web Control Session Timer starts as soon as it receives such a request. The timer is reset upon receipt of every HTTP request. If no HTTP requests are received for five consecutive minutes, the session terminates.

Terminating a Web Control session causes TimeVault to deny any further requests you make for changes. You can immediately activate a new session by logging in again.

4.1 Overview and Format

Shortly after power-up, the utility port will be ready to receive commands. To ensure the unit receives data input accurately, wait until the message Searching for

commands.

You can send data to, or request data from, the unit by sending serial or Telnet commands using ASCII character strings. The general form of these commands is:

where:

has been on the front panel before entering any serial or Telnet

F<FUNC#><Enter>

F = ASCII character F <FUNC#> = two-digit function number <Enter> = input line terminator

Serial or Telnet I/O Functions

More specifically, the data input and output formats are:

F<FUNC#>[<SP><FIELD>]<Enter> (input)

F<FUNC#>[<SP><FIELD>]<CR><LF>

where:

F = ASCII character F <FUNC#> = function number <SP> = space <FIELD> = data entry or request <CR><LF> = output line terminator [ ] = encloses a phrase that is repeated as often as

necessary

Output strings are kept to fixed lengths whenever possible. This means that numeric values often contain many leading blanks. This user’s guide represents output strings in a fixed font. For example:

F60 prn 14 good enabled sig level= +21.37<CR><LF>

(output)

6000-100Ch4.fm Rev. D TimeVault™ User’s Manual 4-49

Chapter 4: Serial or Telnet I/O Functions Overview and Format

The formats of the output strings are designed so that it is possible to request the state of a function and save the response string. Later that string can be sent to the unit to restore the original state of that function.

Input strings sent to the unit may vary in length. The manual represents what you should type in the same fixed font, with a bold typeface. It represents the necessary keyboard action differently, however, as per the manual conventions (page 1-1). For example:

F03<Enter>

The number of separators between fields may vary. You can enter numeric values with or without leading zeros. When entering positive quantities, you can omit the plus sign.

String fields (such as “on” or “off”) may be entered in upper or lower case, as can the “F” that starts all serial or Telnet commands. Some fields of some commands are optional and may be replaced by a semicolon. In that case, the corresponding value is unchanged.

End all input strings by pressing the <Enter> or <Return> key on your keyboard.

An incorrect entry may result in an error message, as described in “Error Messages” on page 5-87. The unit responds to correct entries with:

OK<CR><LF>

In addition to the regular F-series commands, there is also a set of F100 commands, known collectively as Extended Function Commands. With certain F100 commands, you can reconfigure network parameters, such as IP Address, or modify function settings like Remote Lockout. These commands include F100 BASET, IP / SM / G / CONFIG (“set” commands) / DHCP and LOCK. Changes to any of these settings, except F100 LOCK, cause the unit to reset automatically.

After making changes to values in any of these parameters/functions, a confirmation prompt appears (“Are you sure?”). For safety, the default response to this prompt is negative. The unit will not execute the command unless you respond affirmatively by entering the letter “y” within 10 seconds. Within that time period, any other response, including no response, results in the unit canceling the command.

4.2 Command List

The following table lists all serial/Telnet commands that are used to operate, administer, and maintain the unit. The Utility Port is ready to receive these commands once the power-up sequence is complete. The F100 series is used mainly to request or set unit NET Port parameters. Configuration of the IP Address, Subnet Mask, Default Gateway, and DHCP parameters is also available through the front panel keypad. Changing any network parameter causes the unit to reboot.

Use the front panel keypad to set initial system configuration values at first installation.

4.3 Function Commands

4.3.1 F03 – Time and Date Request

Use Function F03 to request time and date. The response is UTC date and time.

To request TIME AND DATE, send the following command:

F03<Enter>

The unit responds:

F03<SP><mm>/<dd>/<yyyy><SP><HH>:<MM>:<SS><CR><LF>

where

F = ASCII character F 03 = function number <SP> = space <mm> = one- or two-digit month / = ASCII character slash <dd> = one- or two-digit day <yyyy> = four-digit year (if you manually entered this data) <HH> = one- or two-digit hours : = ASCII character for a colon <MM> = two-digit minutes <SS> = two-digit seconds ; = replacement character <Enter> = input line terminator <CR><LF> = output line terminator

Sample Entry: F03<Enter>

The response might be:

4.3.2 F18 – Software Version Request

F03 UTC 01/07/1996 02:48:29<CR><LF>

Use Version Request to query the software version number of the unit. The version number is factory set and cannot be changed. This command is for backwards compatibility and is identical to the F100 VER command (see page 4-66).

4-54 TimeVault™ User’s Manual 6000-100Ch4.fm Rev. D

Function Commands Chapter 4: Serial or Telnet I/O Functions

4.3.3 F36 – NET Port Network Configuration Entry/Request

Use Function F36 to request or set network parameters. Changes require the unit to reset. F36 commands are for backward compatibility and are identical to the F100 function command series used for the same purpose (see the sections starting on page 4-59).

F36 commands are for backward compatibility with previous Symmetricom products. F36

and F100 commands can both be used to query or change specific NET Port network parameters.

The F36 EA (and F100 EA) command reports in the Ethernet address IEEE format, which may result in numbers which differ from those reported by your system. Since the Ethernet address is a fixed value, as long as the unit is up and running (you can ping the unit to be sure), you can safely ignore these differences.

4.3.4 F53 – Operating Mode Request

Use Function F53 to verify the number of satellites currently being tracked. F53 also reports the unit’s operating mode, which is always Survey Static.

To see the number of tracked satellites, send the following command:

F53<Enter>

The unit responds:

F53<SP><MODE>:<SP><#><SP>SATS<CR><LF>

where

F = ASCII character F 53 = function number <SP> = space <MODE> = SURVEY STATIC : = ASCII colon <#> = number of satellites being tracked <Enter> = input line terminator <CR><LF> = output line terminator

Sample entry: The response might be:

F53<Enter>

F53 SURVEY STATIC SATS: 6<CR><LF>

Chapter 4: Serial or Telnet I/O Functions Function Commands

4.3.5 F60 – Satellite List Request

Use Function 60 to list current satellites and to see the relative signal strength of satellites the unit is tracking. Signal strength is given in units in the range of 0 to +25.

The unit monitors five variables: the prn number, good/bad, enabled/disabled, tracked, and current.

To request the list, send the following command:

F60<Enter>

where

F = ASCII character F 60 = function number <Enter> = input line terminator

The unit responds:

F60<SP>prn NN<SP>good<SP>enabled<SP>tracked<SP>current<SP> sig<SP>level<SP>= +<LEVEL><CR><LF>

where

prn NN = pseudo-random number; the prn number is a unique

identifier for a particular satellite’s communication path; for example, satellite 3 might have the prn number 15; if that satellite is recalled to Earth and replaced by satellite 42, the communication path of satellite 42 might also be assigned prn 15

enabled/disabled = “Enabled” refers to a factory default configuration

value that allows the GPS to track all satellites on the F60 list

good/bad = “Good” means all three of the following apply:

• the satellite is visible, and

• the satellite’s ephemeris and almanac data report the satellite’s health as “good”, and

• the satellite reports its own health as “good”

“Bad” means at least one of the following applies:

• the satellite is not visible, or

• the satellite’s ephemeris and almanac data report the satellite’s health as “bad”, or

• the satellite reports its own health as “bad” (for example, during maintenance periods)

tracked = “Tracked” means that the unit is tracking this

particular satellite

current = “Current” means that the unit is both tracking this

satellite and using the satellite’s communication to calculate accurate time; an example from the list is prn 3

<CR><LF> = line terminator

4-56 TimeVault™ User’s Manual 6000-100Ch4.fm Rev. D

Function Commands Chapter 4: Serial or Telnet I/O Functions

You can see from the sample list below that “enabled”, “good”, and “tracked” satellites are “current”. That means that the unit does not use any satellite with questionable communication to calculate time, even if that satellite is enabled, visible and being tracked.

Sample entry: F60<Enter>

The response is a current list, an example of which is:

F60 prn 1 bad enabled sig level= +0.00 F60 prn 2 bad enabled sig level= +0.00 F60 prn 3 good enabled tracked current sig level=+13.64 F60 prn 4 bad enabled sig level= +0.00 F60 prn 5 bad enabled sig level= +0.00 F60 prn 6 good enabled sig level= +0.00 F60 prn 7 bad enabled sig level= +0.00 F60 prn 8 bad enabled sig level= +0.00 F60 prn 9 bad enabled sig level= +0.00 F60 prn 10 bad enabled sig level= +0.00 F60 prn 11 bad enabled tracked sig level= +3.00 F60 prn 12 bad enabled sig level= +0.00 F60 prn 13 bad enabled sig level= +0.00 F60 prn 14 bad enabled sig level= +0.00 F60 prn 15 good enabled tracked current sig level=+22.77 F60 prn 16 bad enabled sig level= +0.00 F60 prn 17 good enabled sig level= +0.00 F60 prn 18 bad enabled sig level= +0.00 F60 prn 19 bad enabled sig level= +0.00 F60 prn 20 bad enabled tracked sig level= +3.00 F60 prn 21 good enabled tracked current sig level=+20.15 F60 prn 22 good enabled sig level= +0.00 F60 prn 23 good enabled tracked current sig level=+15.27 F60 prn 24 bad enabled sig level= +0.00 F60 prn 25 bad enabled tracked sig level= +3.47 F60 prn 26 good enabled sig level= +0.00 F60 prn 27 bad enabled sig level= +0.00 F60 prn 28 bad enabled sig level= +0.00 F60 prn 29 good enabled tracked current sig level=+21.46 F60 prn 30 bad enabled sig level= +0.00 F60 prn 31 good enabled tracked current sig level=+18.10 F60 prn 32 bad enabled sig level= +0.00

4.3.6 F67 – Leap Second Information

Use Function 67 to retrieve information regarding upcoming leap seconds. This is satellite information and cannot be changed through the unit. Although UTC leap second adjustments may be performed on four occasions annually, in practice they are only performed twice: June 30th and December 31st.

To return the leap second status, send the following command:

F67<Enter>

where

F = ASCII character F = function number <Enter> = input line terminator <CR><LF> = output line terminator

An example of the response might be:

F67 06/30/96 +1 <CR><LF>

This response indicates there is a leap second addition during the last minute of June 30, 1996.

If there was no leap second pending, the response might be:

4.3.7 F72 – Fault Status Request

Use Function F72 to display the status of the antenna feed circuit, and GPS lock status fault detectors within the unit.

To display the status of the fault detectors, send the following command:

F72<Enter>

The unit responds:

F72<SP>Antenna: <ANT STATUS> GPS: <GPS STATUS><CR><LF>

where:

F = ASCII character F 72 = function number <SP> = space <ANT STATUS> = OPEN, GOOD or SHORTED <GPS STATUS> = LOCKED, UNLOCKED <CR><LF> = output line terminator

Extended Function Commands Chapter 4: Serial or Telnet I/O Functions

4.4 Extended Function Commands

The F100 command series is known collectively as Extended Function Commands. With certain F100 commands, you can reconfigure network parameters, such as IP Address, or modify function settings like Remote Lockout. The main commands include F100 BASET, IP / SM / G / CONFIG (“set” commands) / DHCP, LOCK, UNLOCK and L. Changes to any of these settings, except F100 LOCK, cause the unit to reset automatically after you respond to a confirmation prompt. Other commands are available for changing passwords (PN, PR, PRESETALL, PL, PLS, PLR) and updating software (J, BH, BU, BUB, BF, BL, BLS, BLR), as well as pinging remote hosts (PI) and displaying UTC time in seconds (PT).

For safety, the default response to the confirmation prompt is negative. The unit will not execute the command unless you respond affirmatively (enter the letter “y”) within 10 seconds. Within that time period, any other response, including no response, results in the unit canceling the command.

In those sections below where it is not already stated, <Enter> = input line terminator and <CR><LF> = output line terminator.

F100 Command Configuration Notes:

• Network parameters can be queried at any time, but cannot be changed unless DHCP is disabled first.

• You can reconfigure two or more network parameters in a single entry by sending the F100 command and entering new values. You will have to respond (within 10 seconds) to separate confirmation prompts for each value that you change.

• Leading zeros may be omitted when entering IP Address, Subnet Mask, and Default Gateway.

• Any field may be omitted and order is not significant.

• Blanks are allowed on either side of a colon.

• The unit reboots after any network parameter is changed.

6000-100Ch4.fm Rev. D TimeVault™ User’s Manual 4-59

Chapter 4: Serial or Telnet I/O Functions Extended Function Commands

4.4.1 F100 BASET – 100 BASE-T/10 BASE-T Control

Use the BASET command to query the current Base-T setting. If you set the unit to 10Base-T, it operates only at that speed. If you set the unit to 100Base-T, it negotiates between 10/100Base-T. This does not necessarily mean the unit will connect at 100Base-T, but will connect at the fastest possible speed. Any change to the current Base-T setting causes the unit to reset.

To query the maximum Base-T speed, send the following command:

F100<SP>BASET<Enter>

where

F = ASCII character F 100 = unit function number <SP> = space BASET = specify Base-T command <Enter> = input line terminator

An example of the response is:

F100 BASET 100T

To set the maximum connection speed to 100Base-T, send the following command:

F100<SP>BASET<SP>100<Enter>

where:

100 = set maximum Base-T speed to 100

To set the maximum connection speed to 10Base-T, send the following command:

F100<SP>BASET<SP>10<Enter>

where

10 = set maximum Base-T speed to 10

In both these cases, the unit responds:

Are you sure? (y/N)

As a safety feature, after sending this command, you have 10 seconds to respond affirmatively (enter the letter “y”) to the confirmation prompt, after which the unit executes the command and resets. Within that 10 second time period, any other response, including no response, results in the unit canceling the command.

For details about an initial 100Base-T setting, see “NET Port Network Parameters: First Time Configuration” on page 2-28.

DHCP allows the unit to auto-configure its network address, provided that you have enabled DHCP, and that the unit is installed on, and connected to at power-up, an Ethernet LAN with a DHCP server. If these conditions are not met, the unit reverts to those network parameters in use at the last power-down. By default, DHCP is off at initial installation.

Disable DHCP before changing any Network parameter. Changing DHCP status causes a software reset of the unit. DHCP status can be queried without rebooting the unit.

To enable DHCP, send the following command:

F100<SP>DHCP<SP>ENABLE<Enter>

where:

F = ASCII character F 100 = unit function number <SP> = space DHCP = specify DHCP command ENABLE = command DHCP to be enabled <Enter> = input line terminator

To disable DHCP, send the following command:

F100<SP>DHCP<SP>DISABLE<Enter>

where:

DISABLE = command DHCP to be disabled

The unit responds:

Are you sure? (y/N)

As a safety feature, after sending this command you have 10 seconds to respond affirmatively (enter the letter “y”) to the confirmation prompt, after which the unit executes the command and resets. Within that 10 second time period, any other response, including no response, results in the unit canceling the command.

To query the status of DHCP send:

F100<SP>DHCP<Enter>

An example of the response is:

F100 DHCP OFF

4.4.3 F100 EA – Ethernet Address

The Ethernet address is assigned at the factory. It is a fixed, six-byte, hexadecimal value specific to the unit NET Port. The first three bytes are registered to Symmetricom Inc.; the last three bytes are the hex value identifying the NET Port.

To request the Ethernet address of the unit NET Port, send the following command:

F100 EA<Enter>

The unit responds:

F100 EA:00-A0-69-xx-xx-xx<CR><LF>

where “xx-xx-xx” are the six hex digits of the unit’s unique address.

An example of the response is:

F100 EA:00-A0-69-00-06-2A

Attempts to set this field will be rejected with a syntax error message.

The F100 EA (and F36EA) command reports in the Ethernet address IEEE format, which may result in numbers which differ from those reported by your system. Since the Ethernet address is a fixed value, as long as the unit is up and running (you can ping the unit to be sure), you can safely ignore these differences.

4.4.4 F100 IP – IP Address

To obtain the IP address of the unit NET Port, send the following command:

F100 IP<Enter>

The unit responds:

F100 IP:nnn.nnn.nnn.nnn<CR><LF>

where “nnn.nnn.nnn.nnn” is the dotted decimal address notation.

An example of the response is:

F100 IP:206.54.0.33

Changing the IP Address requires the unit to reset. A verification prompt appears prior to execution.

To set the IP address and restart the unit, send the following command:

F100 IP:nnn.nnn.nnn.nnn<Enter>

Sample entry: F100 IP:206.54.0.21<Enter> The response is:

4.4.8 F100 P – Change User Password

If you want to change a password, you must log in as the user for whom you want to change the password (also see page 4-86). The maximum password size is ten characters.

To change the user password, send the following command:

F100<SP>P<Enter>

where:

F = ASCII character F 100 = unit function number <SP> = space P = specify Password command <Enter> = input line terminator

The unit responds:

Enter new user password:

When you enter a new password, the unit responds with:

Enter it again:

Enter the same new password again, to confirm the spelling. If the same new password has been entered twice, the unit responds with:

OK<CR><LF>

In this case, the new password will be used for the next login (serial or Telnet). However, if the new password is entered differently the second time, the unit responds with:

ERROR: Passwords do NOT match. New password rejected.

In this case, the old password will be used for the next login (serial or Telnet).

If you have forgotten your user name and/or password, you can go into bootloader mode and reset them. In bootloader mode the unit recognizes the default user name and password. You can then use F100 PR (see page 4-83) or F100 PRESETALL (see page 4-82) to change the user name and password to defaults for use in the normal mode, or you can use F100 PN (see page 4-82) and F100 P (the above command) to

Editing the MD5 keys on the NTP Server

NTP keys are needed if you are using NTP in broadcast mode with MD5 authentication. This (and the following) section provide configuration guidelines. For a discussion of using NTP in broadcast mode without MD5 authentication, see Appendix B.

The Broadcast mode adjusts its periodicity according to feedback from its broadcast client. The periodicity will typically settle-out to about every 2 minutes. This activity is not adjustable.

MD5 private keys have to be edited on both the NTP server and the NTP client. The private keys are defined in the “ntp.keys” file.

4-70 TimeVault™ User’s Manual 6000-100Ch4.fm Rev. D

Extended Function Commands Chapter 4: Serial or Telnet I/O Functions

The NTP client “ntp.keys” file is identical to the one on the NTP server. For the specific keys used by the NTP server, the NTP client must have the identical line in its version of the file. You’ll want to use your own hard-to-guess key names, using random letters. The critical lines of the “ntp.keys” file are:

Id M Value

---- --- --------

1 M Symmetricom

2 M xyz123

where 1 and 2 are key identifiers.

The first column is the key identification number, which may range in whole positive numbers from 1 to 65,535. The second column is the type of key, which is always set to the letter M when using MD5 authentication. The third column is the private key that is ASCII text from 1 to 32 characters in length.

For maximum security, use a unique combination of 32 letters and numbers for each key

identifier. For correct configuration, do not use zero as a key identifier. Zero means the key identification will not be used.

Editing the MD5 keys on the NTP Client

For NTP client authentication, the line trustedkey 1 2 in the “ntp.conf” file is required to enable the private keys 1 and 2 from the “ntp.keys” file. The line bclient is required for broadcast time packets to be processed by the NTP client. In this case, sample information from a client “ntp.conf” file might look like:

trustedkey 1 2

bclient

Sample information in a client “ntp.keys” file might look like:

1 M Symmetricom

2 M longshot

When you invoke the NTP client at the command line, use the following options:

•–b to turn on broadcast reception

• –k /etc/ntp.keys to specify the name and location of the keys file

–d

• for debugging.

An example command line might look like:

ntpd –d –d –d –b –k /etc/ntp.keys

After configuring all MD5 keys, carry out step 4 in the configuration procedure outlined above.

Configuration of SNMP Parameters Using FTP

By default, SNMP is disabled. To use it, or to configure any other SNMP parameter using FTP and a text editor, follow the steps outlined below. However, it is much faster and easier to do this remotely, using the web interface (see “Remote SNMP Configuration” on page 3-38). During this process, the FTP software creates a default configuration file (“snmp.conf”) in your directory to hold the data you have requested. Do not change the name of this file.

1. Send a “get” command:

Sample Entry: F100 config get snmp host:192.168.1.14
