1.1 Getting Started

1.1 Getting Started

Figure 1-1: VersaSync Rugged GPS Time & Frequency Reference

Welcome to the VersaSync User Manual .

First steps:

If you are not yet familiar with VersaSync, you may want to start here: "VersaSync

Overview" below.

If you are ready to begin the installation process, see: "Initial Network Setup" on

page29

If your unit is already up and running, and you would like to change specific settings, see …

… "Managing Time" on page135, or

… "System Administration" on page207.

1.2 VersaSync Overview

VersaSync is a high-performance time & frequency GPS master clock and network time server that delivers accurate, software configurable time and frequency signals under all circumstances, including GNSS-denied environments. Its compact size and high level of ruggedization make VersaSync suitable for mobile applications in harsh environments. VersaSync's small footprint allows for easy integration of the time and frequency functionality into systems architecture.

VersaSync includes all the timing functionality required in modern, network-centric applications:

CHAPTER 1 • VersaSync User Manual Rev. 7.0

Page 17

1.2 VersaSync Overview

NTP/PTP precise time transfer over Ethernet, including security protocols that prevent network vulnerabilities

Low phase noise 10 MHz frequency distribution

Configurable pulse signals, including IRIG or HaveQuick timecodes

Serial link Time Of Day (ToD) messages

GPS-Denied Environments

VersaSync accommodates an OCXO oscillator, allowing the unit to maintain frequency and time accuracy for long periods of GPS/GNSS outage. In addition, it can be re-synchronized by an external reference.

Reliable, Versatile, and Configurable

VersaSync physical inputs and outputs are software configurable and can adapt to various application requirements. I/O pins can be configured as TTL, 10 V pulse, RS232, RS422, and RS485. This allows VersaSync to provide a high number of outputs of the same type, while still fitting into a small form factor. However, if the combination of software configurable outputs is not enough, VersaSync can accommodate an option board (within the same form factor), designed to customer requirements to provide additional outputs of the same type orother type of interface (IRIG AM, etc…).

Due to its high level of ruggedization, VersaSync provides very high intrinsic reliability. Strong status monitoring capability, either locally or remotely, allows quick fault diagnosis. Physical alarm (dry contact) and network alarms (SNMP traps) are raised in real time. An internal, exportable log can be accessed either locally or remotely. In addition to oscillator options (OCXO), VersaSync is available with a C/A L1 GPS receiver or with an L1/L2 SAASM receiver. Pulse outputs are configurable through the web user interface ("Web UI"). An extension slot is available to accommodate additional timing interfaces.

Typical Applications

Airborne: Observation payload (radars, optronics, electronic warfare), flying test

bench, flight analysis

Ground: Satcom On the Move (SOTM), anti-IED jamming systems, mobile radios and

C3I, robotics

Marine: Sensor support (radars, sonars, optronics, electronic warfare), com-

munication networks, offshore/DSO platforms, buoys

1.3 Status LEDs

1.3 Status LEDs

VersaSync's front panel status LEDs provide a real-time status overview: Eight (8) LEDs indicate the unit's current operating state:

The LEDs can be disabled, see "Blackout Mode" on page6.

1.3.1 Blinking Intervals

The statusLEDs can communicate five different operating states:

"OFF"

"ON"

"FAST": blinking interval @ 8Hz

"SLOW": blinking interval @ 2Hz

"HEARTBEAT": sinus-shaped interval @ 1Hz

1.3.2 LED Lighting Patterns

The table below indicates LED status light patterns for common VersaSync operating statuses.

1.4 Interfaces Overview

1.3.3.1 LED Patterns during Boot Sequence

For the first five seconds after power-up all LEDs will be OFF. Then the Power LED will be blinking before it will be lit permanently. If you have configured your unit to operate in Blackout Mode, this will take effect once the blinking cycle ends.

1.3.4 Blackout Mode

All LEDs can be turned off via the WebUI.

The LED brightness level can be set from 63 (as bright as possible) to 0 (not visable).

To disable all LED activity via the WebUI:

Navigate to MANAGEMENT > OTHER: LED Configuration, and set the Brightness level to "0".

1.4 Interfaces Overview

All of VersaSync's interfaces are integrated into the unit's connectors, which are located on the front panel:

2.2.2 Mounting

2.2.2.1 Selecting a Mounting Location

The unit is to be mounted on a plate, using six (6) through holes. The mounting location must offer sufficient space to accommodate the unit and the cable connectors, and it must be within cable reach to other connected devices, such as the GNSS antenna. The unit can be mounted horizontally, or at any angle. The chosen environment must not fall below IP 65 ingress protection standards.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 43

Figure 2-1: Mechanical dimensions

2.2.2.2 Heat Dissipation

The aluminum base plate of the unit acts as a heat drain, conducting heat away from VersaSync's interior components. When considering a mounting location, it is crucial that:

the operating temperature of the mounting surface does not exceed 71°C/149°F.

the mounting surface is even and heat conductive. Do not use any insulator material e.g., rubber gaskets or similar.

the ambient air temperature meets is within the specified range, i.e. -40°C to +71°C.

2.2.2.3 Fasteners

Spectracom recommends to observe the VITA 75 standard regarding mounting the unit, and fastener selection.

2.3 Initial Network Setup

2.2.2.4 Grounding

The VersaSync's DC power is not isolated from the chassis; during operation, the negative DC of the power source becomes the ground of the chassis. Typical AC "earth ground" measures are unnecessary because of this design.

Should you opt to ground your VersaSync directly to your vehicle, connect the DC negative terminals of the power connector to the chassis of the unit and to the vehicle metallic structure. Doing so will send the negative DC directly to the vehicle, rather than the power supply. Use a grounding strap if the baseplate can't make metal-to-metal contact with the mounting surface.

2.3 Initial Network Setup

After making the hardware connections outlined in the Installation Overview list, the following information will help you to establish a network connection. Your connection instructions will vary depending on your chosen physical connections.

If your unit is connected to your network, you can quickly find and communicate

with your VersaSync web user interface ("Web UI", used to configure and monitor the unit)

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 44

2.3 Initial Network Setup

If your unit is connected directly to a PC via the USB connection or an Ethernet

port: VersaSync has a Command Line Interpreter ("CLI"). You will need a ter-

minal emulator program installed on the PC that will be used to configure Ver-

saSync in order to communicate. Follow the instructions below, or see "Setting up a

Terminal Emulator" on page271 for more detailed instructionsand a list of CLI com-

mands. Using the serial CLI connection, you can set up access to the Web UI by setting or identifying an IP address on your network. (See "Assigning a Static IP

Address" on page36).

Default settings:

VersaSync network settings default to static IP addresses. The Ethenet ports come preconfigured with IP addresses as follows:

via the default IP address, and a PC configured with the same subnet mask (255.255.255.0)

using a DHCP-assigned address and a PC also connected to your network. For more information, see "Zero Configuration Setup" on page34.

Eth0 - 192.168.1.1

Eth1 - 192.168.1.2

Default subnet mask: 255.255.255.0

2.3.1 USB Driver

If you are using a USB connection through the multi I/O connector, driver installation may be necssary. On the PC connected to the unit, new hardware (the USB interface) will be detected. The correct driver should be installed automatically. If not, download the driver fromwww.ftdichip.com/Drivers/VCP.htm, and install it manually via the instructions for your operating system.

2.3.2 Network Connection

Start the terminal emulator program on the PC. Select the COM port that is assigned to the USB interface:

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 45

2.3 Initial Network Setup

Access the CLI via ssh or telnet: The required port configuration is 115200 8N1:

Press the Return key, and enter the login credentials:

Note: The default login credentials are:

User name = spadmin Password = admin123 (will not be displayed on the screen)

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 46

2.4 Accessing the WebUI

If you are on a DHCP-enabled network, you can assign an IP address by enabling DHCP on your unit. Use the dhcp4set <x> on command, (x being 0/1 for ETH0

and ETH1, respectively).

Retrieve the IP address assigned to VersaSync by typing the net4 command. The command should return the network settings, including the IP address.

Note: For your reference, the command helpcli produces a list of avail-

able commands. Press the space key to display the next page, or the

b key to display the previous page.

Note: Should it become necessary to leave the command help mode

(indicated by a command line prompt ":"), press Q, or Ctrl C.

You can use this IP address to login to the VersaSync Web UI and then set a static IP address, subnet mask and gateway. (This can also be done via the CLI and a terminal emulator. See "Assigning a Static IP Address" on page36).

If you are NOT on a DHCP-enabled network, your unit's IP address is set to the default for each Ethernet port, unless you have assigned a new static IP address.

For more detailed information about setting a static IPaddress for your unit, see "Setting

up an IP Address" on page35

Or, proceed to "Accessing the WebUI" below (it is recommended that you have identified or set your unit IP address for this step).

2.4 Accessing the WebUI

VersaSync's WebUI is the recommended tool to interact with the device, since it provides access to nearly all configurable settings, and obtain comprehensive status information

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 47

2.4 Accessing the WebUI

without having to use the Command Line Interpreter (CLI).

You can access the Web UI either by using the default IP address, an automatically assigned DHCP IP address, or by using a manually set static IP address (see "Assigning a

Static IP Address" on page36).

On a PC connected to VersaSync via ETH1 or ETH0, start a web browser.

Navigate to the IP address assigned or identified in "Initial Network Setup" on

page29.

Log into the Web UI as an administrator. The factory-default administrator user name and password are:

Username: spadmin

Password: admin123

Note: For security reasons, it is advisable to change the default cre-

dentials; see: "Managing Passwords" on page223.

Upon initial login, you will be asked to register your product. Spectracom recommends to register VersaSync, soas to receive software updates and services notices. See also "Product Registration" on page343.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 48

2.5 Zero Configuration Setup

2.5 Zero Configuration Setup

As an alternative to conventional network configuration, VersaSync can also be set up using the zero-configuration networking technology ("zeroconf").

Note: You can use Zeroconf on either Ethernet port if DHCP is enabled.

Zeroconf must be used with a DHCP server.

When using zeroconf, a TCP/IP network will be created automatically, i.e. without the need for manual configuration: Once VersaSync's ETH connector is connected to a network, you can directly access the VersaSync WebUI, using a standard web browser, without any configuration.

Zeroconf can be used to connect to the unit through the Web UI:

when you need to identify the IP address assigned to your unit through DHCP (DHCP must be enabled through the Web UI or CLI)

in circumstances when your unit isnot connected directly to a PC

when you wish to access the Web UI of your VersaSync without using the CLI commands or serial connection

anytime the IP addressof a unit is not known

Zeroconf Requirements

Prior to using zeroconf, ensure the following requirements are met:

Your network is DHCP enabled, and DHCPis enabled on the individual ETH port you are using.

The PC you will use to communicate with your unit is connected to the same network as your VersaSync.

Windows 7/8 users should install Bonjour Print Services, otherwise access to *.local addresses will not be possible.

Windows 10 already supports mDNS and DNS-SD, hence there isno need to install additional software.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 49

2.5.1 Using Zeroconf

Connect to the Web UI of your VersaSync unit in these steps:

Check the serial number label on the side of the unit, and write down the last 6 digits of the MAC 0 address: e.g., "0C 00 19". Note that you will use the same MAC

address for either Ethernet port.

Connect the VersaSync to a router on your LAN via the ETH connector (see "Initial

Network Setup" on page29).

Connect the power supply to the VersaSync unit.

On a connected computer, open your web browser and in the URL field type the following:

where the [xxxxxx] of the hostname are the last six digits of the MAC0 address you copied from the serial number label on the unit.

You should now be prompted for a username and password. The factory default credentials are:

Note: If you do not have physical access to the unit, you can obtain the MAC

0 address by accessing VersaSync's CLI via the I/O connector USB port, using e.g., the ifconfig command.

Once you logged into the VersaSync via zeroconf, you can retrieve the DHCP address for future use:

Navigate to MANAGEMENT: NETWORK > Network Setup. In the Ports panel, click on the information button next to each Ethernet port. The popup window will display the assigned DCHP IP address for the selected port.

See "Setting up an IP Address" below or "Accessing the WebUI" on page32 for more information.

2.6 Setting up an IP Address

In order for VersaSync to be accessible via your network, you need to assign an IP address to VersaSync, as well as a subnet mask and gateway, unless you are using an address assigned by a DHCP server.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 50

2.6 Setting up an IP Address

Before you continue …

… please obtain the following information from the system network administrator:

Available static IP address

Subnet mask (for the network)

Gateway address

This is the unique address your network administrator will assign to your VersaSync unit. Make sure the chosen addressis outside of the DHCP range of your DHCP server.

The subnet mask defines the number of bits taken from the IP address that are used in the network portion. The number of network bits used in the net mask can range from 8 to 30bits.

The gateway (default router) address is needed if communication to the VersaSync is made outside of the local network. By default, the gateway is disabled.

2.6.1 Assigning a Static IP Address

There are two ways to setup a permanent static IP address, after connecting VersaSync to a network:

Assigning a Static IP Address Using the CLI:

Note: For your reference, the command helpcli produces a list of available

commands. Press the space key to display the next page, or the b key to display the previous page. To leave the command help file, press Q or Ctrl C.

Open the serial console, using a terminal emulator program

If necessary, disable DHCP – Command: dhcp4set <x> off (where x is 0/1 for

ETH0 and ETH1, respectively).

Set the static IP address – Command: ip4set <x>.<IP address>.<subnet mask> Example: ip4set 0 10.2.100.245 255.255.0.0

If required, also set your gateway address: gw4set <x> <gateway address>

Verify that the address has been accepted – Command: net4

If so required, turn DHCP back on – Command: dhcp4set [x] on

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 51

Assigning a Static IP Address Using the Web UI:

Enter the IP address identified during setup ("Initial Network Setup" on page29) into the address field of your browser (on a computer connected to the VersaSync network). If the network supportsDNS, the hostname may also be entered instead (the default hostname is "Spectracom"). The start screen of the VersaSync Web UI will be displayed.

Log into the Web UI as an administrator. The factory-default user name and password are:

Username: spadmin Password: admin123

If necessary, disable DHCP by navigating to MANAGEMENT > Network Setup. In the Ports panel on the right, click the GEAR icon next to the Ethernet Port you are using. In the Edit Ethernet Port Settings window, uncheck the Enable DHCPv4 field. Do NOT click Submit or Apply until you complete the next step to avoid error messages.

In the fields below the Enable DHCPv4 checkbox, enter the desired Static IP address, Netmask, and Gateway address (if required). Click Submit.

2.7 Configuring Inputs/Outputs

This Section covers the configuration of the inputs and outputs of the I/O connector.

When you configure an input our output via the I/O connector, you will need to adjust both the pin configuration ("Assigning I/O Pins" on the facing page) and (for some types) the settings for that input or output via the Web UI ("Configure I/O Input and Output Set-

tings" on page44).

Figure 2-2: I/O connector

For more information on the I/O connector, see "Connectors and their Pinouts" on

page9.

Note: The GNSS input reference as well as the 10 MHz outputs are not fed

into the unit via the I/O connector and are therefore not explained in this Chapter; for instructions on how to configure the GNSS reference, see

"The GNSS Reference" on page171 in the Chapter MANAGINGTIME.

Note: The Network Ports eth0 and eth1 can be configured under

MANAGEMENT > Network Setup. For more information, see "Configuring

Network Settings" on page62.

2.7.1.1 Signal Types

The table below shows the maximum number of available interfaces for each signal type. Note that you can assign only one signal for each pin pair, hence only four to nine input and output signals can be transmitted/received at any given time. For details, see the signal mapping table below.

Table 2-2:

Note: ASCII Time Code is abbreviated in the UI as ATC.

Available signal types

DCLS Signal Lines

Up to six TTL (5V) or 10V DCLS outputs and three DCLS inputs are available for e.g., 1PPS, xPPS, IRIG, HaveQuick, ASCII ToD signal transmission.

Single-ended Serial Lines

VersaSync provides up to 3 RX and 3 TX RS232 interfaces for e.g., ASCII ToD – NMEA 0183 (ICD-GPS-153).

Differential Serial Lines

Up to four differential serial lines are available. Each of them can be set to RS485 electrical standard, and used as input or output. PPS or Time-of-Day messages are available, as well as HAVE QUICK and other formats. Note that this kind of interface uses two Channels.

Non-Configurable Pins

Channel # 0 provides a DCLSTTL output signal that is not user-configurable.

Also note that pins # 19 through 26 are reserved for the USB command line interface.

2.7.1.2 I/O Signal Mapping Table

Each Channel (i.e., each pin pair e.g., "3&4" = Channel 1) can serve as only one interface, and not all combinations are possible due to the internal multiplexer architecture.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

2.7.4.4 Configuring an ASCII Output

About the ASCII Format Outputs

The ASCII outputs (ATC = ASCII Time Code) provide VersaSync with the ability to output one, two or three back-to-back ASCII time code data streams that can be provided to peripheral devices which accept an ASCII RS-232 or RS-485 input data stream for either their external time synchronization or for data processing. See "Time Code Data Formats" on

page277 for a description of all supported time code formats.

The RX signal on an output interface is used for triggering the output ASCII message output when a configured character is received from the peripheral device.

When VersaSync is configured to output only one format message (the second and third formats configured as “None”), the one configured message will be available on the output port as either a broadcast message or only upon a request character being received. VersaSync has the ability to output one or two additional data stream messages immediately

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 66

2.7 Configuring Inputs/Outputs

following the first message. In this configuration, only the first message determines the ontime point for the entire output string. The on-time points for the second and third messages that are provided at the same time as the first message are discarded. This unique capability allows VersaSync to be able to simultaneously provide multiple pieces of data from different selected format messages.

An example of selecting multiple formats is selecting “NMEA GGA” as the first format, “NMEA RMC” as the second format and “NMEA ZDA” as the third format. Depending on the setting of the “Mode” field (which determines if the data streams are available every second or upon a request character being received), at the next second or the receipt of the next request character, the output port will provide the GGA message followed immediately by the corresponding RMC message for that same second, followed immediately by the corresponding ZDA message for that same second. The first GGA message will provide the on-time point for the entire output data stream.

To configure an ASCII Output:

Signature Control: Signature Control controls when the selected ASCII data

output format will be present;see "Signature Control" on page60.

Output Mode: This field determines when the output data will be provided.

The available Mode selections are as follows:

Broadcast: The format messages are automatically sent out on author-

ized condition (Signature control), every second a message is generated in sync with the 1PPS.

Request (On-time): A format message is generated in sync with 1PPS

after the configured request character has been received.

Request (Immediate): A format message is generated as soon as the

request character is received. As this selection does not correlate the output data to the on-time point for the message, in Data Formats that do not provide sub- second information (such as Formats 0 and 1 whereas Format 2 provides sub-second information), it should be noted that the output data can be provided immediately, but a time error could occur when using the on-time point of the message in addition to the data for timing applications.

Note: The choices available in this field are determined

by the choices of Format Group and Format.

Timescale: Used to select the time base for the incoming data. The entered

Timescale is used by the system to convert the time in the incoming data stream to UTC time for use by the System Time. The available choices are:

2.7.4.5 Event Broadcast (ASCII Output)

The Event Broadcast functionality is available without a license through the multi-I/O connector and configured through the WebUI. The Event Broadcast system consists of an Event Input and an Event Broadcast output. Both the input and output for this fuctionality have settings and options.

When the defined signal edge is detected on the Event Input GPIO Connector, an ASCII message is created containing the current time, and Event Broadcast through the RS232 Output port.

ASCII messages are stored in a Message Buffer . The message buffer can store 512entries before overflowing. Messages may be lost if the buffer overflows.

Messages can be output in one of two ways:

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 69

2.7 Configuring Inputs/Outputs

If the Mode is set to Broadcast, messages in the Message Buffer will be output immediately. If another event is captured while a message is being sent, it will be queued in the buffer until the first message completes, then the next message will be sent.

If the Mode is set to Request, messages in the Message Buffer are only sent when the Request Character is received.

The output format used is selected among a small group of formats with the capability to output data at 5ns resolution. Event Broadcast Output formats are detailed in "Event

Broadcast Time Code Formats" on page327.

available formats. Event Broadcast only supports two formats (Event Broadcast Format 0 and Event Broadcast Format 1), and only supports the output of one message per event. If format is set to “None”, no messages will be queued in the Message Buffer.

Output Mode: This field determines when the output data will be provided.

Available Mode selections are as follows:

Broadcast—Event Messages are automatically broadcast when they

are created by an event. If a new event happens while an older message is being broadcast, the new message will be queued in a “First-in, First-out” manner. When the message has finished, the next message out of the queue will be broadcast.

Request— [default: t] Event Messages are only broadcast in response

to a Request Character. New messages will be queued in a “First-in, First-out” manner.

Timescale—Used to select the time base for the incoming ASCII time code

data. The entered Timescale is used by the system to convert the time in the incoming ASCII data stream to UTC time, in order to produce the Event Broadcast (always in UTC). The available choices are:

UTC—Coordinated Universal Time ("temps universel coordonné"), also

referred to asZULU time

2.7.5 Signature Control

Signature Control is a user-set parameter that controls under which output states an out-

put will be present. This feature allows you to determine how closely you want to link an output to the status of the active input reference e.g., by deactivating it after holdover expiration. It is also offers the capability to indirectly send an input-reference-lost-alarm to a downstream recipient via the presence of the signal.

E X A M P L E S :

You can setup Signature Control such that VersaSync's built in 1PPS output becomes disabled the moment its input reference is lost (e.g., if a valid GNSS signal is lost).

Or, you can setup your output signal such that remains valid while VersaSync in holdover mode, but not in free run.

The available options are:

Output Always Enabled—The output is present, even if VersaSync is not syn-

chronized to its references (VersaSync isfree running).

II.

Output Enabled in Holdover—The output is present unless VersaSync is not syn-

chronized to its references (VersaSync isin Holdover mode).

2.8 Configuring Network Settings

IPv4 Gateway : The gateway (default router) address is needed if com-

munication to the VersaSync is made outside of the local network. By default, the gateway is disabled.

Domain: This is the domain name to be associated with this port.

DNS Primary : This is the primary DNS address to be used for this port.

Depending on how your DHCP server is configured, this is set automatically once DHCP is enabled. Alternatively, you may configure your DHCP server to NOT use a DNS address. When DHCP is disabled, DNS Primary is set manually, using the format "#.#.#.#" with no leading zeroes or spaces, where each ‘#’ isa decimal integer from the range [0,255].

DNS Secondary: This is the secondary DNS address to be used for this port.

Depending on how your DHCP server is configured, this is set automatically once DHCP is enabled, or your DHCP server may be configured NOT to set a DNS address. When DHCP is disabled, DNS Secondary is set manually, using the format “#.#.#.#” with no leading zeroes or spaces, where each ‘#’ is a decimal integer from the range [0,255].

MTU: Maximum Transmission Unit. Range (for Ethernetv2): Default: 1500

bytes. Smaller packages are recommended, if encapsulation is required e.g., to meet encryption needs, which would cause the maximum package size to be exceeded.

To apply your changes, click Submit (the window will close), or Apply.

2.8.3 Network Services

been entered. When switching between tabs within the HTTPS Setup window, the inform- ation you have entered will be retained.

2.8.5.2 About HTTPS

HTTPS provides secure/encrypted, web-based management and configuration of VersaSync from a PC. In order to establish a secure HTTPS connection, an SSL certificate must be stored inside the VersaSync unit.

VersaSync uses the OpenSSL library to create certificate requests and self-signed certificates. The OpenSSL library provides the encryption algorithms used for secure HTTP (HTTPS). The OpenSSL package also provides tools and software for creating X.509 Certificate Requests, Self Signed Certificates and Private/Public Keys. For more information on OpenSSL, please see www.openssl.org.

Once you created a certificate request, submit the request to an external Certificate Authority (CA) for the creation of a third party verifiable certificate. (It is also possible to use an internal corporate Certificate Authority.)

If a Certificate Authority is not available, or while you are waiting for the certificate to be issued, you can use the default Spectracom self-signed SSL certificate that comes with the unit until it expires, oruse your own self-signed certificate. The typical life span of a certificate (i.e., during which HTTPS is available for use) is about 10years.

Note: If deleted, the HTTPS certificate cannot be restored. A new cer-

tificate will need to be generated.

Note: In a Chrome web browser, if a valid certificate is deleted or changed

such that it becomes invalid, it is necessary to navigate to Chrome's Settings> More Tools> Clear browsing data> Advanced and clear the Cached

images and files in the history. Otherwise Chrome's security warnings may

make some data unavailable in the Web UI.

Note: If the IP Address or Common Name (Host Name) is changed, you

need to regenerate the certificate, or you will receive security warnings from your web browser each time you log in.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 85

2.8.5.3 Supported Certificate Formats

VersaSync supports X.509 PEM and DER Certificates, as well as PKCS#7 PEM and DER formatted Certificates.

You can create a unique X.509 self-signed Certificate, an RSA private key and X.509 certificate request using the WebUI. RSA private keys are supported because they are the most widely accepted. At this time, DSA keys are not supported.

2.8.5.4 Creating an HTTPS Certificate Request

Caution: If you plan on entering multiple Subject Alternative Names to your

HTTPS Certificate Request, you must do so before filling out the Create Certificate Request tab to avoid losing any information. See "Adding

HTTPS Subject Alternative Names" on page74.

2.8 Configuring Network Settings

To create an HTTPS Certificate Request:

Navigate to MANAGEMENT > NETWORK: HTTPS Setup, or in the MANAGEMENT > NETWORK Setup, Actions panel, select HTTPS:

Click the Create Certificate Request tab (this is the default tab).

Check the box Create Self Signed Certificate, in order to open up all menu items.

This checkbox serves as a security feature: Check the box only if you are certain about generating a new self-signed Certificate.

Caution: Once you click Submit, a previously generated Certificate

(or the Spectracom default Certificate) will be overwritten.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

2.8 Configuring Network Settings

Note that an invalid Certificate may result in denial of access to VersaSync via the Web UI!

Fill in the available fields:

Signature Algorithm: Choose the algorithm to be used from:

Private Key Pass Phrase: This is the RSA decryption key. This must be at

least 4characters long.

RSA Private Key Bit Length: 2048 bits is the default. Using a lower number

may compromise security and is not recommended.

Two-Letter Country Code: This code should match the ISO-3166-1 value

for the country in question.

State Or Province Name: From the addressof the organization creating up

the Certificate.

Locality Name: Locale of the organization creating the Certificate.

Organization Name: The name of the organization creating the Certificate.

Organization Unit Name: The applicable subdivision of the organization cre-

ating the Certificate.

Common Name (e.g. Hostname or IP): This is the name of the host being

authenticated. The Common Name field in the X.509 Certificate must match the hostname, IP address, or URL used to reach the host via HTTPS.

Email Address: This is the email address of the organization creating the Cer-

tificate.

Challenge Password: Valid response password to server challenge.

Optional Organization Name: An optional name for the organization cre-

ating the Certificate.

Self-Signed Certificate Expiration (Days): How many days before the Cer-

tificate expires. The default is 7200.

You are required to select a signature algorithm, a private key passphrase of at least 4characters, a private key bit length, and the Certificate expiration in days. The remaining fields are optional.

It is recommended that you consult your Certificate Authority for the required fields in an X509-Certificate request. Orolia recommends all fields be filled out and match the information given to your Certificate Authority. For example, use all

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 87

2.8 Configuring Network Settings

abbreviations, spellings, URLs, and company departments recognized by the Certificate Authority. This helps to avoid problems the Certificate Authority might otherwise have reconciling Certificate request and company record information.

If necessary, consult your web browser vendor’s documentation and Certificate Authority to see which key bit lengths and signature algorithms your web browser supports.

Orolia recommends that when completing the Common Name field, the user provide a static IP address, because DHCP-generated IP addresses can change. If the hostname or IP address changes, the X.509 Certificate must be regenerated.

It is recommended that the RSA Private Key Bit Length be a power of 2 or multiple of 2. The key bit length chosen is typically 1024, but can range from 512 to 4096. Long key bit lengths of up to 4096 are not recommended because they can take several hours to generate. The most common key bit length is the value 1024.

Note: The default key bit length value is 2048.

When using a self-signed Certificate, choose values based on your company’s security policy.

When the form is complete, confirm that you checked the box Create Self Signed

Certificate at the top of the window, then click Submit. Clicking the Submit but-

ton automatically generates the Certificate Request in the proper format for subsequent submission to the Certificate Authority.

Note: It may take several minutes for VersaSync to create the Cer-

tificate request and the private key (larger keys will require more time than small keys). If the unit is rebooted during this time, the Certificate will not be created.

To view the newly generated request, in the HTTPS Setup window, click the Cer-

tificate Request tab.

When switching between tabs within the HTTPS Setup window, the information you have entered will be retained. If you exit the HTTPS Setup window before click- ing Submit, the information will be lost.

2.8.5.5 Adding HTTPS Subject Alternative Names

Caution: Subject Alternative Names must be added before a new Cer-

tificate Request is generated, otherwise the Certificate Request will have to be created again to include the Subject Alternative Names. Any information entered into the Create Certificate Request tab that has not been submitted will be lost by adding, deleting, or editing Subject Alternative Names.

It is recommended that you consult your Certificate Authority regarding questions of Subject Alternative Name usage.

2.8.5.6 Requesting an HTTPS Certificate

Before requesting an HTTPS Certificate from a third-party Certificate Authority, you need to create a Certificate Request:

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 90

2.8 Configuring Network Settings

Navigate to MANAGEMENT > HTTPS Setup, or to MANAGEMENT > Network

Setup > Actions panel: HTTPS.

In the HTTPS Setup window, under the Certificate Request Parameters tab, com- plete the form as described under "Creating an HTTPS Certificate Request" on

page71.

Click Submit to generate your Certificate Request.

You have now created a Certificate Request. Navigate to the Certificate Request tab to view it:

Copy the generated Certificate Request fromthe Certificate Request window, and paste and submit it per the guidelines of yourCertificate Authority. The Certificate Authority will issue a verifiable, authenticable third-party certificate.

OPTIONAL: While waiting for the certificate to be issued by the Certificate Authority, you may use the certificate from the Certificate Request window as a self-signed certificate (see below).

NOTE: Preventing accidental overwriting of an existing certificate:

If you plan on using a new Certificate Request, fill out a new form under the Certificate

Request Parameters tab. Be aware, though, that the newly generated Certificate

Request will replace the Certificate Request previously generated once you submit it. Therefore, if you wish to retain your previously generated Certificate Request for any reason, copy its text, and paste it into a separate text file. Save the file before generating a new request.

Using a Self-Signed Certificate

In the process of generating a Certificate Request, a self-signed certificate will automatically be generated simultaneously. It will be displayed under the Certificate Request

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 91

tab.

You may use your self-signed certificate (or the default Spectracom self-signed certificate that comes with the unit) while waiting for the HTTPS certificate from the Certificate Authority, or – if a Certificate Authority is not available – until it expires. The typical life span of a certificate is about 10years.

NOTE: When accessing the VersaSync WebUI while using the self-signed certificate, your

Windows®web browser will ask you to confirm that you want to access this site via https with only a self-signed certificate in place. Other operating systems may vary in how they install and accept certificates. External Internet access may be required by your Certificate Authority to verify your certificate.

2.8.5.7 Uploading an X.509 PEM Certificate Text

Many Certificate Authorities simply issue a Certificate in the form of a plain text file. If your Certificate was provided in this manner, and the Certificate is in the X.509 PEM format, follow the procedure below to upload the Certificate text by copying and pasting it into the WebUI.

2.8 Configuring Network Settings

Note: Only X.509 PEM Certificates can be loaded in this manner. Cer-

tificates issued in other formats must be uploaded via the Upload Cer-

tificate tab.

Note: VersaSync will automatically format the Certificate into the

X.509 PEM format.

SSH uses host keys to uniquely identify each SSH server. Host keys are used for server authentication and identification. A secure unit permits users to create or delete RSA or DSA keys for the SSH2 protocol.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

2.8 Configuring Network Settings

Note: Only SSH2 is supported due to vulnerabilities in the SSH1 protocol.

The SSH tools supported by VersaSync are:

SSH: Secure Shell

SCP: Secure Copy

SFTP: Secure File Transfer Protocol

VersaSync implements the server components of SSH, SCP, and SFTP.

For more information on OpenSSH, please refer to www.openssh.org.

To configure SSH:

Navigate to MANAGEMENT > NETWORK: SSH Setup. The SSH Setup window will display.

The window contains two tabs:

Host Keys: SSH uses Host Keys to uniquely identify each SSH server. Host

keys are used for server authentication and identification.

Public Key: This is a text field interface that allows the user to edit the public

key files authorized_keys file.

Note: Should you exit the SSH Setup window (by clicking X in the top

right corner of the window, or by clicking anywhere outside of the window), while filling out the Certificate Request Parameters form before clicking Submit, any information you entered will be lost. When switching between tabs within the SSH Setup window, however, the information you have entered willbe retained.

Host Keys

You may choose to delete individual RSA or DSA host keys. Should you decide to delete the RSA or DSA key, the SSH will function, but that form of server authentication will not be available. Should you delete both the RSA and DSA keys, SSH will not function. In addition, if SSH host keys are being generated at the time of deletion, the key generation processes are stopped, any keys created will be deleted, and all key bit sizes are set to 0.

You may choose to delete existing keys and request the creation of new keys, but it is often simpler to make these requestsseparately.

You can create individual RSA and DSA Host Public/Private Key pairs. Host keys must first be deleted before new Host Keys can be created.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

2.8 Configuring Network Settings

VersaSync units have their initial host keys created at the factory. RSA host key sizes can vary between 768 and 4096 bits. The recommended key size is 1024. Though many key sizes are supported, it is recommended that users select key sizes that are powers of 2 or divisible by 2. The most popular sizes are 768, 1024, and 2048. Large key sizes of up to 4096 are supported, but may take 10 minutes or more to generate. DSA keys size support is limited to 1024 bits.

Host keys are generated in the background. Creating RSA and DSA keys, each with 1024 bits length, typically takes about 30 seconds. Keys are created in the order of RSA, DSA, RSA. When the keys are created, you can successfully make SSH client connections. If the unit is rebooted with host key creation in progress, or the unit is booted and no host keys exist, the key generation process is restarted. The key generation process uses either the previously specified key sizes or, if a key size is undefined, the default key bit length size used is 2048. A key with a zero length or blank key size field is not created.

The SSH client utilities SSH, SCP, and SFTP allow for several modes of user authentication. SSH allows you to remotely login or transfer files by identifying your account and the target machine's IP address. As a user you can authenticate yourself by using your account password, or by using a Public Private Key Pair.

It is advisable to keep your private key secret within your workstation or network user account, and provide the VersaSync a copy of your public key. The modes of authentication supported include:

Either Public Key with Passphrase or Login Account Password

Public Key with Passphrase only

SSH using public/private key authentication is the most secure authenticating method for SSH, SCP or SFTP sessions.

You are required to create private and public key pairs on your workstation or within a private area in your network account. These keys may be RSA or DSA and may be any key bit length as supported by the SSH client tool. These public keys are stored in a file in the

.ssh directory named authorized_keys. The file is to be formatted such that the key is

followed by the optional comment with only one key per line.

Note: The file format, line terminations, and other EOL or EOF characters

should correspond to UNIX conventions, not Windows.

Changing Key Length Values

You may change the key length of the RSA, DSA, ECDSA type host keys.

To change the key length of a host key:

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 96

2.8 Configuring Network Settings

Navigate to MANAGEMENT > NETWORK: SSH Setup. The SSH Setup window will open to the Host Keys tab by default.

Select the Key Length value for the key type you want to change.

Key sizes that are powers of 2 or divisible by 2 are recommended. The most popular sizes are 768, 1024, and 2048. Large key sizes of up to 4096 are supported, but may take 10 minutes or more to generate. DSA keys size support is limited to 1024 bits. The key type ED25519 supports 256 bits.

Check the Regenerate All Keys box.

Click Submit. The new values will be saved.

Note: Changing the values and submitting them in this manner DOES NOT

generate new host public/private key pairs. See "Creating Host Public/Priv-

ate Key Pairs" below for information on how to create new host pub-

lic/private key pairs.

Deleting Host Keys

You can delete individual host keys. To delete a key:

Navigate to MANAGEMENT > NETWORK: SSH Setup. The window will open to the Host Keys tab by default.

Select Delete in the field for the key you wish to delete, and click Submit.

Creating Host Public/Private Key Pairs

You may create individualHost Public/Private Key pairs. Host keys must first be deleted before new Host Keys can be created. To create a new set of host keys:

To access the SSH setup screen, navigate to MANAGEMENT > NETWORK: SSH

Setup. The window will open to the Host Keys tab by default.

Should you want to change the key length of any host key, enter the desired length in the text field corresponding to the length you wish to change.

Check the Regenerate All Keys box.

Click Submit. The KeyType/Status/Action table will temporarily disappear while the VersaSync regenerates the keys. The Host keys are generated in the background. Creating RSA and DSA keys, each with 1024 bits length, typically takes about 30 seconds. Keys are created in the order of RSA, DSA, ECDSA, ED25519. VersaSync will generate all 4 host keys, RSA, DSA, ECDSA, and ED25519.

Delete any of the keys you do not want. See "Deleting Host Keys" above.

Note: If the unit is rebooted with host key creation in progress, or

the unit is booted and no host keys exist, the key generation process is restarted. The key generation process uses the previously specified key sizes.

Note: If a key size is undefined, the default key bit length size used is

2048. A key with a zero length or blank key size field will not be created.

When you delete a host key and recreate a new one, SSH client sessions will warn you that the host key has changed for this particular IP address. You must then take one of the following actions:

Override the warning and accept the new Public Host Key and start a new connection. This is the default. This option allows users to login using either method. Whichever mode works is allowed for logging in. If the Public Key is not correct or the Passphrase is not valid the user is then prompted for the login account password.

Remove the old Host Public Key fromtheir client system and accept the new Host Public Key. Thisoption simply skips public/private key authentication and immediately prompts the user for password over a secure encrypted session avoiding sending passwords in the clear.

Load a public key into VersaSync. This public key must match the private key found in the users account and be accessible to the SSH, SCP, or SFTP client program. The user must then enter the Passphrase after authentication of the keys to provide the second factor for 2-factor authentication.

Please consult your specific SSH client’s software’s documentation.

Public Keys: Viewing, Editing, Loading

The authorized_keys file can be viewed and edited, so as to enable adding and deleting Public Keys. The user may also retrieve the authorized_keys file from the .ssh directory Using FTP, SCP, or SFTP.

If you want to completely control the public keys used for authentication, a correctly formatted authorized_keys file formatted as indicated in the OpenSSH web site can be

loaded onto VersaSync. You can transfer a new public key file using the Web UI.

To view and edit the authorized_keys file:

Navigate to MANAGEMENT > NETWORK: SSH Setup. The SSH Setup window will open to the Host Keys tab by default.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

Page 98

2.8 Configuring Network Settings

Select the Public Key tab. The authorized_keys file appearsin the Public Keys

File window:

Edit the authorized_keys file as desired.

Click the Submit button or Apply button.

The file is to be formatted such that the key is followed by an optional comment, with only one key per line. The file format, line terminations, and other EOL or EOF characters should correspond to UNIX conventions, not Windows.

Note: If you delete ALL Public Keys, Public/Private Key authentication is dis-

abled. If you have selected SSH authentication using the Public Key with

Passphrase option, login and file transfers will be forbidden. You must

select a method allowing the use of account password authentication to enable login or file transfers using SCP or SFTP.

Editing the "authorized_key" File via CLI

Secure shell sessions using an SSH client can be performed using the admin or a userdefined account. The user may use Account Password or Public Key with Passphrase authentication. The OpenSSH tool SSH-KEYGEN may be used to create RSA and DSA keys used toidentify and authenticate user login or file transfers.

The following command lines for OpenSSH SSH client tool are given as examples of how to create an SSH session.

Creating an SSH session with Password Authentication for the admin account

ssh spadmin@10.10.200.5

spadmin@10.10.200.5's password: admin123

You are now presented with boot up text and/or a “>” prompt which allows the use of the Spectracom command line interface.

CHAPTER 2 • VersaSync User Manual Rev. 7.0

2.8 Configuring Network Settings

Creating an SSH session using Public Key with Passphrase Authentication for the admin account

You must first provide the secure Orolia product a RSA public key found typically in the OpenSSH id_rsa.pub file. Then you may attempt to create an SSH session.

ssh -i ./id_rsa spadmin@10.10.200.5

Enter passphrase for key './id_rsa': mysecretpassphrase

Please consult the SSH client tool’s documentation for specifics on how to use the tool, select SSH protocols, and provide user private keys.

Secure File Transfer Using SCP and SFTP

VersaSync provides secure file transfer capabilities using the SSH client tools SCP and SFTP. Authentication is performed using either Account Passwords or Public Key with Passphrase.

Example output from OpenSSH, SCP, and SFTP client commands are shown below.

Perform an SCP file transfer to the device using Account Password authentication

scp authorized_keys scp@10.10.200.5:.ssh

spadmin@10.10.200.135's password: admin123

publickeys 100% |***************************************************| 5 00:00

Perform an SCP file transfer to the device using Public Key with Passphrase authentication.

scp -i ./id_rsa spadmin@10.10.200.5:.ssh

Enter passphrase for key './id_rsa': mysecretpassphrase

publickeys 100% |***************************************************| 5 00:00

Perform an SFTP file transfer to the device using Account Password authentication.

sftp spadmin@10.10.200.5

spadmin@10.10.200.135's password: admin123

You will be presented with the SFTP prompt allowing interactive file transfer and directory navigation.

Recommended SSH Client Tools

Orolia does not make any recommendations for specific SSH clients, SCP clients, or SFTP client tools. However, there are many SSH based tools available to the user at low cost or free.

Two good, free examples of SSH tool suites are the command line based tool OpenSSH running on a Linux or OpenBSD x86 platform and the SSH tool suite PuTTY.

The OpenSSH tool suite in source code form is freely available at www.openssh.org though you must also provide an OpenSSL library, which can be found at

www.openssl.org.

PuTTY can be found at: http://www.chiark.greenend.org.uk/~sgtatham/putty/.

SSH Timeout

The keep-SSH alive timeout is hard-set to 7200 seconds. This value isnot configurable.

2.8.7 SNMP

SNMP (Simple Network Management Protocol) is a widely used application-layer protocol for managing and monitoring network elements. It has been defined by the Internet Architecture Board under RFC-1157 for exchanging management information between network devices, and is part of the TCP/IP protocol.

SNMP agentsmust be enabled and configured so that they can communicate with the network management system (NMS). The agent is also responsible for controlling the database of control variables defined in the Management Information Base (MIB).

VersaSync’s SNMP functionality supports SNMP versions V1, V2c and V3 (with SNMP Version3 being a secure SNMP protocol).

Once SNMP is configured it will persist through reboot, and only needs to be reconfigured after performing a "clean" update process (thus restoring the factory default condition).

Note: In order to configure SNMP, you need ADMINISTRATORrights.
