This section covers some other interesting topics relating to the NavisWorks License Manager.
You should only change the server port number if the default port number clashes with another port in use on your server. The default port number (3697) is registered with the Internet Assigned Names Authority (IANA) for use by the JetStream License Server, so is unlikely to clash with other services.
To change the default port number that the server uses to serve its JetStream licenses, do the following:
Make sure that no JetStream clients are connected to the server.
Stop the NavisWorks Licensing service from the Services dialog (from Administration Tools) on the server.
Open the NavisWorks License Manager and choose Network server from the License Wizard menu.
You should now be able to change the Port Number
Click Finish to save the new Port number, or Cancel to return to the License Manager.
Restart the NavisWorks Licensing service from the Services dialog (from Administration Tools) on the server.
Make sure that any client PCs accessing licenses from the server now have the same port number that the server is using. This is changed from the client PC, again from the Network Server dialog under the License Wizard menu in the NavisWorks License Manager.
When using floating and networked licenses, Client machines must maintain a network connection with the License Server. Once a Client machine has collected a license from the License Server, the Server will send out a "heartbeat" every two minutes, to check the connection with the Client and whether the license is still in use.
If a situation arises, whereby the connection is lost, (whether there is a network problem or the license has been >killed by the server) then the following may be expected:
On the License Server , every two minutes the "heartbeat" will be sent out to the Client. If after eight minutes the connection has not been re-established, then the License Server will automatically take back the license.
On the Client machine , if after two minutes a "heartbeat" has not been received from the License Server, a message will be displayed advising the connection has been lost and recommend you save any work. At this time you will continue to have the full functionality of the license. If after eight minutes the connection has not been re-established, JetStream will be unlicensed and therefore automatically close.
From this tab you can manage your JetStream license in detail.
The text boxes in the Machine Information section may be useful when resolving licensing issues and communicating licensing information with NavisWorks Ltd.
Machine name is the name of the machine the license manager is running on, complete with its domain or workgroup name - this is its fully qualified domain name (FQDN).
Machine ID is a series of coded characters used to uniquely identify the machine. The first part of this, ID: , is the CrypKey ID used for CrypKey ID Locking. The second part of this, ET: , is the Ethernet ID used for Ethernet ID Locking
Crypkey ID expiry is the date that a time-limited license will expire, for example when using JetStream during an evaluation, or grace period.
Crypkey site code is the software code required by NavisWorks Ltd. for emergency licensing. See Emergency Licensing for more information.
You can actually view the license file in Notepad by clicking on the View License File button. This will show all the licenses and codes that make JetStream work, but be warned that changing this file can seriously damage and invalidate your JetStream licenses. The View Last Message button is useful in case you need to re-view the last message information, such as if licensing fails and you need to pass on the information to your support provider.
The Display server console message window can only be used on a JetStream License Server machine. Check this option if you wish a DOS window to open each time the NavisWorks Licensing service is started on the server. This DOS box can give useful information about what is actually happening in this background service. This may be of particular use when trying to identify a connection problem between the License Server and a Client machine.
Closing the DOS window will stop the NavisWorks Licensing service (although the Windows Services panel will still report it to be started). If you don't require the message window any longer, uncheck the option in the Advanced tab, then manually Restart the NavisWorks Licensing service.
Crypkey ID locking and Ethernet ID locking are the two methods that JetStream uses to lock a license to a machine. Crypkey ID locking is the JetStream method of software locking and Ethernet ID locking is the JetStream method of hardware locking. At least one of these should be checked and by default, both are and should remain checked.
If there is no Ethernet card inside your PC (or you use multiple cards), you cannot use Ethernet ID locking and should instead use only Crypkey ID locking. This will mean, though, that you will not be able to use the Recover license functionality if you were to lose your license later.
Sometimes the CrypKey service can be problematic to run on PCs of certain configurations, particularly when a RAID disk subsystem is in use. Un-checking this option and relying instead only on Ethernet ID locking can make it easier to install licenses in these circumstances. However, this will mean that you will not be able to Return licenses for transferring to another PC.
These options matter if your machine changes configuration for whatever reason between first installing your licenses and accessing them. Two specific situations are:
1. If you have to recover a license when, for example, a machine crashes, make sure that you have the same combination of Crypkey/Ethernet ID locking options checked as when you first licensed the machine.
2. If your laptop PC uses a docking station in the office that contains the Ethernet card and it cannot access the Ethernet card when undocked, then you should not check the Ethernet ID locking option when requesting your license, if you want to access the licenses when undocked.
As explained in the License Manager Options, it is important to use the same combination of Crypkey ID locking and Ethernet ID locking when first licensing your machine as when recovering or returning licenses. In addition, the following conditions should be understood:
If you only use Crypkey ID locking, then you cannot recover a license. Contact <support@navisworks.com> if you need to recover a license that is locked using only Crypkey ID locking.
If you only use Ethernet ID locking, then you cannot return a license. Contact <support@navisworks.com> if you need to return a license that is locked using only Ethernet ID locking.
In certain situations it may not be possible to license your JetStream product by any of the standard methods. There is therefore, an emergency licensing procedure that can be performed by NavisWorks Ltd. This method will only be used as a last resort.
Using the >CrypKey Site Code from the Advanced tab on your PC, NavisWorks Ltd. will generate and return a CrypKey Site Key . Enter this into the Emergency licensing box and then click the License button. This will unlock the licenses on your PC.
