If you are licensing VNC Server using license keys, a new key will be generated when your subscription renews. You'll need to re-license. I'm running VNC Server Personal Edition on my home laptop. When I try to connect to it, I get the following message: Server license. So long as you have a valid VNC Connect subscription, the key is valid. You will need to ensure you are running the latest version of VNC Server.

An operation, described in the log message, was attempted but could not proceed, and the failure of this operation is a serious problem that needs to be addressed. Warnings are generally non-fatal conditions.
The operation continued, but encountered noteworthy problems. They may be useful or interesting to administrators, but are not generally critical to proper operation of a Guacamole server. Debug messages are highly detailed and oriented toward development.
Most debug messages will contain stack traces and internal information that is useful when investigating problems within code. It is expected that debug messages, though verbose, will not affect performance. Trace messages are similar to debug messages in intent and verbosity, but are so low-level that they may affect performance due to their frequency. Trace-level logging is rarely necessary, and is mainly useful in providing highly detailed context around issues being investigated. If you wish to change the log level, or configure how or where Guacamole logs messages, you can do so by providing your own logback.
Guacamole and the above example configure only one appender which logs to the console, but Logback is extremely flexible and allows any number of appenders which can each log to separate files, the console, etc. This authentication module comes with Guacamole and simply reads usernames and passwords from an XML file.
It is always enabled, but will only read from the XML file if it exists, and is always last in priority relative to any other authentication extensions. There are other authentication modules available. The Guacamole project provides database-backed authentication modules with the ability to manage connections and users from the web interface, and other authentication modules can be created using the extension API provided along with the Guacamole web application, guacamole-ext.
An example of a user mapping file is included with Guacamole, and looks something like this:. When using user-mapping. In the example above, the password would be listed in plaintext. After modifying user-mapping. The newly-added user will be able to log in - no restart of the servlet container is needed. Each protocol supported by Guacamole has its own set of configuration parameters.
These parameters typically describe the hostname and port of the remote desktop server, the credentials to use when connecting, if any, and the size and color depth of the display. If the protocol supports file transfer, options for enabling that functionality will be provided as well. The VNC protocol is the simplest and first protocol supported by Guacamole. VNC support for Guacamole is provided by the libguac-client-vnc library, which will be installed as part of guacamole-server if the required dependencies are present during the build.
Disabling clipboard access. File transfer via SFTP. Graphical session recording. Each VNC server is associated with a display number, from which the appropriate port number is derived. For example, if your VNC server is serving display number 1 sometimes written as :1 , your port number here would be The number of times to retry connecting before giving up and returning an error.
In the case of a reverse connection, this is the number of times the connection process is allowed to time out. The VNC standard defines only password based authentication. Other authentication mechanisms exist, but are non-standard or proprietary. Guacamole currently supports both standard password-only based authentication, as well as username and password authentication. VNC servers do not allow the client to request particular display sizes, so you are at the mercy of your VNC server with respect to display width and height.
However, to reduce bandwidth usage, you may request that the VNC server reduce its color depth. Guacamole will automatically detect color images, but this can be guaranteed for absolutely all graphics sent over the connection by forcing the color depth to 8-bit.
Color depth is otherwise dictated by the VNC server. If you are noticing problems with your VNC display, such as the lack of a mouse cursor, the presence of multiple mouse cursors, or strange colors such as blue colors appearing more like orange or red , these are typically the result of bugs or limitations within the VNC server, and additional parameters are available to work around such issues.
The color depth to request, in bits-per-pixel. This parameter is optional. If specified, this must be either 8, 16, 24, or Regardless of what value is chosen here, if a particular update uses less than colors, Guacamole will always send that update as a color PNG. If the colors of your display appear wrong blues appear orange or red, etc.
A remote mouse cursor will feel slower than a local cursor, but may be necessary if the VNC server does not support sending the cursor image to the client. A space-delimited list of VNC encodings to use. This parameter is optional, and libguac-client-vnc will use any supported encoding by default. Beware that this parameter is intended to be replaced with individual, encoding-specific parameters in a future release.
Whether this connection should be read-only. Users will only see the desktop and whatever other users using that same desktop are doing. Whether this connection should only use lossless compression for graphical updates. By default, lossy compression will be used when heuristics determine that it would likely outperform lossless compression. Additional parameters are required to select which VNC host behind the repeater will receive the connection. This is only necessary if the VNC proxy in use requires the connecting user to specify which VNC server to connect to.
If the VNC proxy automatically connects to a specific server, this parameter is not necessary. When reverse VNC connections are used, the VNC client and server switch network roles, but otherwise function as they normally would. Whether reverse connection should be used.
If reverse connection is in use, the maximum amount of time to wait for an inbound connection from a VNC server, in milliseconds. If blank, the default value is five seconds. Most Linux systems provide audio through a service called PulseAudio. This service is capable of communicating over the network, and if PulseAudio is configured to allow TCP connections, Guacamole can connect to your PulseAudio server and combine its audio with the graphics coming over VNC.
This loads the TCP module for PulseAudio, configuring it to accept connections without authentication and only from the You will want to replace this value with the subnet or IP address from which guacd will be connecting. It is possible to allow connections from absolutely anywhere, but beware that you should only do so if the nature of your network prevents unauthorized access:. Guacamole does not currently support the cookie-based authentication used by PulseAudio for non-anonymous connections.
If this parameter is omitted, Guacamole will not be able to connect to PulseAudio. Once the PulseAudio configuration file has been modified appropriately, restart the PulseAudio service. You can verify this using a utility like netstat :. By default, audio support within VNC is disabled. The name of the PulseAudio server to connect to. This will be the hostname of the computer providing audio for your connection via PulseAudio, most likely the same as the value given for the hostname parameter.
If this parameter is omitted, the default PulseAudio device will be used, which will be the PulseAudio server running on the same machine as guacd. As most VNC servers will not accept data in any other format, Guacamole will translate between UTF-8 and ISO when exchanging clipboard data with the VNC server, but this behavior can be overridden with the clipboard-encoding parameter. You should only override the clipboard encoding using the clipboard-encoding parameter of you are absolutely positive your VNC server supports other encodings.
The encoding to assume for the VNC clipboard. By default, the standard encoding ISO will be used. Unless your VNC server specifies otherwise, this encoding is the only encoding guaranteed to work. UTF-8 - the most common encoding used for Unicode. This parameter value should only be used if you know your VNC server supports this encoding.
Code page - a Windows-specific encoding for Latin characters which is mostly a superset of ISO , mapping some additional displayable characters onto what would otherwise be control characters. The connection will use VNC to connect to localhost at port Naturally, you will want to change some or all of these values. Other authentication methods will provide documentation describing how to configure new connections.
You will not need to edit configuration files. The choice of VNC server can make a big difference when it comes to performance, especially over slower networks. While many systems provide VNC access by default, using this is often not the fastest method. In our testing, they perform the best with Guacamole.
If you are okay with having a desktop that can only be accessed via VNC, one of these is likely your best choice. Both optimize window movement and depending on the application scrolling, giving a very responsive user experience. This is because images transmitted to Guacamole are always encoded losslessly as PNG images. The main benefit of using x11vnc is that it allows you to continue using your desktop normally, while simultaneously exposing control of your desktop via VNC.
If you need to use your desktop locally as well as via VNC, you will likely be quite happy with x11vnc. If you need to share your local desktop, we recommend using x11vnc rather vino, as it has proven more performant and feature-complete in our testing. If you need to see the virtual monitor of your virtual machine, using this VNC connection is really your only choice. As the VNC server built into QEMU cannot be aware of higher-level operations like window movement, resizing, or scrolling, those operations will tend to be sent suboptimally, and will not be as fast as a VNC server running within the virtual machine.
If you wish to use a virtual machine for desktop access, we recommend installing a native VNC server inside the virtual machine after the virtual machine is set up. This will give a more responsive desktop. RDP support for Guacamole is provided by the libguac-client-rdp library, which will be installed as part of guacamole-server if the required dependencies are present during the build. RDP connections require a hostname or IP address defining the destination machine. The RDP port is defined to be , and will be this value in most cases.
You only need to specify the RDP port if you are not using port The port the RDP server is listening on. RDP provides authentication through the use of a username, password, and optional domain. All RDP connections are encrypted. Most RDP servers will provide a graphical login if the username, password, and domain parameters are omitted.
One notable exception to this is Network Level Authentication, or NLA, which performs all authentication outside of a desktop session, and thus in the absence of a graphical interface. Servers that require NLA can be handled by Guacamole in one of two ways. The first is to provide the username and password within the connection configuration, either via static values or by passing through the Guacamole credentials with parameter tokens and LDAP authentication. Alternatively, if credentials are not configured within the connection configuration, Guacamole will attempt to prompt the user for the credentials interactively, if the versions of both guacd and Guacamole Client in use support it.
If either component does not support prompting and the credentials are not configured, NLA-based connections will fail. The security mode to use for the RDP connection. This mode dictates how data will be encrypted and what type of authentication will be performed, if any.
By default, a security mode is selected based on a negotiation process which determines what both the client and the server support. Automatically select the security mode based on the security protocols supported by both the client and the server.
This is the default. This mode uses TLS encryption and requires the username and password to be given in advance. Unlike RDP mode, the authentication step is performed before the remote desktop session actually starts, avoiding the need for the Windows server to allocate significant resources for users that may not be authorized.
If the versions of guacd and Guacamole Client in use support prompting and the username, password, and domain are not specified, the user will be interactively prompted to enter credentials to complete NLA and continue the connection. Otherwise, when prompting is not supported and credentials are not provided, NLA connections will fail.
Extended Network Level Authentication. Legacy RDP encryption. This mode is generally only used for older Windows servers or in cases where a standard Windows login screen is desired. Newer versions of Windows have this mode disabled by default and will only accept NLA unless explicitly configured otherwise. Note that this refers to authentication that takes place while connecting. Any authentication enforced by the server over the remote desktop session such as a login dialog will still take place.
By default, authentication is enabled and only used when requested by the server. Windows uses a different sequence of characters at the end of each line compared to other operating systems. As RDP preserves the format of line endings within the clipboard, this can cause trouble when using a non-Windows machine to access Windows or vice versa.
If clipboard normalization is used, Guacamole will automatically translate the line endings within clipboard data to compensate for the expectations of the remote system. The type of line ending normalization to apply to text within the clipboard, if any.
By default, line ending normalization is not applied. Preserve all line endings within the clipboard exactly as they are, performing no normalization whatsoever. Automatically transform all line endings within the clipboard to Unix-style line endings LF. This format of line ending is the format used by both Linux and Mac.
RDP sessions will typically involve the full desktop environment of a normal user. Although Guacamole is independent of keyboard layout, RDP is not. By default, the US English qwerty keyboard will be used. If this does not match the keyboard layout of your RDP server, keys will not be properly translated, and you will need to explicitly choose a different layout in your connection settings.
If your keyboard layout is not supported, please notify the Guacamole team by opening an issue in JIRA. When connecting to the RDP server, Guacamole will normally provide its own hostname as the name of the client.
If this parameter is specified, Guacamole will use its value instead. The server-side keyboard layout. This is the layout of the RDP server and has nothing to do with the keyboard layout in use on the client. The Guacamole client is independent of keyboard layout. The RDP protocol, however, is not independent of keyboard layout, and Guacamole needs to know the keyboard layout of the server in order to send the proper keys when a user is typing.
The timezone that the client should send to the server for configuring the local time display of that server. This will be converted by RDP into the correct format for Windows. The timezone is detected and will be passed to the server during the handshake phase of the connection, and may used by protocols, like RDP, that support it.
This parameter can be used to override the value detected and passed during the handshake, or can be used in situations where guacd does not support passing the timezone parameter during the handshake phase guacd versions prior to 1. Support for forwarding the client timezone varies by RDP server implementation. Windows Server installations in admin mode, along with Windows workstation versions, do not allow the timezone to be forwarded.
Other server implementations, for example, xrdp, may not implement this feature at all. Consult the documentation for the RDP server to determine whether or not this feature is supported. Guacamole will automatically choose an appropriate display size for RDP connections based on the size of the browser window and the DPI of the device.
The size of the display can be forced by specifying explicit width or height values. To reduce bandwidth usage, you may also request that the server reduce its color depth. Color depth is otherwise dictated by the RDP server. If specified, this must be either 8, 16, or The width of the display to request, in pixels. If this value is not specified, the width of the connecting client display will be used instead.
The height of the display to request, in pixels. If this value is not specified, the height of the connecting client display will be used instead. The desired effective resolution of the client display, in DPI. If this value is not specified, the resolution and size of the client display will be used together to determine, heuristically, an appropriate resolution for the RDP session.
The method to use to update the RDP server when the width or height of the client display changes. If this value is not specified, no action will be taken when the client display changes size. Normally, the display size of an RDP session is constant and can only be changed when initially connecting.
As of RDP 8. For older RDP servers, the only option is to disconnect and reconnect with the new size. Automatically disconnects the RDP session when the client display size has changed, and reconnects with the new size. Device redirection refers to the use of non-display devices over RDP. Audio redirection will be enabled by default. If Guacamole was correctly installed, and audio redirection is supported by your RDP server, sound should play within remote connections without manual intervention.
Printing requires GhostScript to be installed on the Guacamole server, and allows users to print arbitrary documents directly to PDF. When documents are printed to the redirected printer, the user will receive a PDF of that document within their web browser.
Guacamole provides support for file transfer over RDP by emulating a virtual disk drive. This drive will persist on the Guacamole server, confined within the drive path specified. If drive redirection is enabled on a Guacamole RDP connection, users will be able to upload and download files as described in Using Guacamole. Audio is enabled by default in both the client and in libguac-client-rdp. By default, audio input support within RDP is disabled. By default, direct RDP support for multi-touch events is disabled.
Enabling support for multi-touch allows touch interaction with applications inside the RDP session, however the touch gestures available will depend on the level of touch support of those applications and the OS. If multi-touch support is not enabled, pointer-type interaction with applications inside the RDP session will be limited to mouse or emulated mouse events. Printing is disabled by default, but with printing enabled, RDP users can print to a virtual printer that sends a PDF containing the document printed to the Guacamole client.
Printing support requires GhostScript to be installed. If guacd cannot find the gs executable when printing, the print attempt will fail. The name of the redirected printer device that is passed through to the RDP session. This is the name that the user will see in, for example, the Devices and Printers control panel. File transfer is disabled by default, but with file transfer enabled, RDP users can transfer files to and from a virtual drive which persists on the Guacamole server.
If set to true downloads from the remote server to client browser will be disabled. The default is false, which means that downloads will be allowed. If set to true, uploads from the client browser to the remote server location will be disabled. The default is false, which means uploads will be allowed if file transfer is enabled.
The name of the filesystem used when passed through to the RDP session. The directory on the Guacamole server in which transferred files should be stored. This directory must be accessible by guacd and both readable and writable by the user that runs guacd.
This parameter does not refer to a directory on the RDP server. Only the final directory in the path will be created - if other directories earlier in the path do not exist, automatic creation will fail, and an error will be logged.
By default, the directory specified by the drive-path parameter will not automatically be created, and attempts to transfer files to a non-existent directory will be logged as errors. A comma-separated list of static channel names to open and expose as pipes.
If you are using Hyper-V, you will need to specify the ID of the destination virtual machine within the preconnection-blob parameter. This value can be determined using PowerShell:. The preconnection PDU is intentionally generic. While its primary use is as a means for selecting virtual machines behind Hyper-V, other RDP servers may use it as well. In most cases, you will need to do the following when connecting to Hyper-V:. Hyper-V may use a self-signed certificate.
This is a non-negative integer value dictating which of potentially several logical RDP connections should be used. This parameter is optional, and is only required if the RDP server is documented as requiring it. If using Hyper-V, this should be left blank. This parameter is optional, and is only required if the RDP server is documented as requiring it, such as Hyper-V. For Hyper-V, this will be the ID of the destination virtual machine.
If you will be using Guacamole to connect through such a gateway, you will need to provide additional parameters describing the connection to that gateway, as well as any required credentials. The hostname of the remote desktop gateway that should be used as an intermediary for the remote desktop connection. If omitted, a gateway will not be used.
The port of the remote desktop gateway that should be used as an intermediary for the remote desktop connection. The username of the user authenticating with the remote desktop gateway, if a gateway is being used. This is not necessarily the same as the user actually using the remote desktop connection.
The password to provide when authenticating with the remote desktop gateway, if a gateway is being used. The domain of the user authenticating with the remote desktop gateway, if a gateway is being used. This is not necessarily the same domain as the user actually using the remote desktop connection.
RDP does not dictate the format of this information; it is specific to the balancer in use. If you are using a load balancer and are unsure whether such information is required, you will need to check the documentation for your balancer.
If your balancer provides. The load balancing information or cookie which should be provided to the connection broker. If no connection broker is being used, this should be left blank. RDP provides several flags which control the availability of features that decrease performance and increase bandwidth for the sake of aesthetics, such as wallpaper, window theming, menu effects, and smooth fonts.
These features are all disabled by default within Guacamole such that bandwidth usage is minimized, but you can manually re-enable them on a per-connection basis if desired. By default, wallpaper will be disabled, such that unnecessary bandwidth need not be spent redrawing the desktop. By default, theming within RDP sessions is disabled.
Text over RDP is rendered with rough edges by default, as this reduces the number of colors used by text, and thus reduces the bandwidth required for the connection. By default, the RDP server will only draw the window border while windows are being dragged. By default, such effects, if available, are disabled.
Menu animations are disabled by default. This parameter allows that to be controlled in a Guacamole session. RDP normally maintains caches of regions of the screen that are currently not visible in the client in order to accelerate retrieval of those regions when they come into view. This is usually only useful when dealing with known bugs in RDP server implementations and should remain enabled in most circumstances.
Glyph caching is currently universally disabled, regardless of the value of this parameter, as glyph caching support is not considered stable by FreeRDP as of the FreeRDP 2. Recent versions of Windows provide a feature called RemoteApp which allows individual applications to be used over RDP, without providing access to the full desktop environment. If your RDP server has this feature enabled and configured, you can configure Guacamole connections to use those individual applications.
Specifies the RemoteApp to start on the remote desktop. If supported by your remote desktop server, this application, and only this application, will be visible to the user. Windows requires a special notation for the names of remote applications. The names of remote applications must be prefixed with two vertical bars. For example, if you have created a remote application on your server for notepad.
The working directory, if any, for the remote application. This parameter has no effect if RemoteApp is not in use. The command-line arguments, if any, for the remote application. The connection will use RDP to connect to localhost at port Other options are available for controlling the color depth, size of the screen, etc. SSH support for Guacamole is provided by the libguac-client-ssh library, which will be installed as part of guacamole-server if the required dependencies are present during the build.
Guacamole includes two methods for verifying SSH and SFTP server identity that can be used to make sure that the host you are connecting to is a host that you know and trust. If the file is not present, no verification is done. If the file is present, it is read in at connection time and remote host identities are verified against the keys present in the file. The second method for verifying host identity is by passing a connection parameter that contains an OpenSSH known hosts entry for that specific host.
If these parameters are not present on their respective connections no host identity verification is performed. If the parameter is present then the identity of the remote host is verified against the identity provided in the parameter before a connection is established. SSH connections require a hostname or IP address defining the destination machine. SSH is standardized to use port 22 and this will be the proper value in most cases. You only need to specify the SSH port if you are not using the standard port.
The port the SSH server is listening on, usually If this is not specified, the default of 22 will be used. The known hosts entry for the SSH server. This parameter is optional, and, if not provided, no verification of host identity will be done. If the parameter is provided the identity of the server will be checked against the data. By default the SSH client does not send keepalive requests to the server. This parameter allows you to configure the the interval in seconds at which the client connection sends keepalive packets to the server.
The default is 0, which disables sending the packets. The minimum value is 2. Generally for this authentication method you need only provide a username. For Guacamole to use public key authentication, it must have access to your private key and, if applicable, its passphrase. If the private key requires a passphrase, but no passphrase is provided, you will be prompted for the passphrase upon connecting.
If no private key is provided, Guacamole will attempt to authenticate using a password, reading that password from the connection parameters, if provided, or by prompting the user directly. The username to use to authenticate, if any. If not specified, you will be prompted for the username upon connecting. The password to use when attempting authentication, if any. If not specified, you will be prompted for your password upon connecting.
The entire contents of the private key to use for public key authentication. If this parameter is not specified, public key authentication will not be used. The passphrase to use to decrypt the private key for use in public key authentication. This parameter is not needed if the private key does not require a passphrase.
If the private key requires a passphrase, but this parameter is not provided, the user will be prompted for the passphrase upon connecting. By default, SSH sessions will start an interactive shell. Modifying the Path user variable instead of the Path system variable might cause the license server to fail to start.
Errors may occur as a result of incorrect configuration of HTTPS for connections between the management interface and the license server. This error occurs if your SSL certificate for the license server is self signed or privately signed and has not been imported into the truststore file.
If the truststore file does not contain your certificate, the JRE disallows connections to the license server because the JRE cannot determine the CA that signed the certificate. When the connection to the license server is disallowed, the following error message appears in the license server management interface:. This error occurs if the keystore password and the keypair password are different. A mismatch between the keystore password and the keypair password prevents the license server from starting.
The keystore password controls access to the keystore in which a self-signed certificate is created. The keypair password controls access to the keystore entry for the certificate. These passwords are set when the self-signed certificate is created. When this error occurs, the following error message is written to the license server log file:. To resolve this issue, change either the keystore password or the keypair password to ensure that both passwords match.
In a Windows Command Prompt window or a Linux shell window, run the following command:. Perform this task in a Windows Command Prompt window or a Linux shell window. Obtain the alias name for accessing the keystore entry for the keypair password you are changing. Change the keypair password of the keystore entry whose alias you obtained in the previous step. If you start the license server uninstaller from Windows Control Panel or Windows Explorer , how it runs depends on the mode in which license server software was installed.
If the license server software was installed in console mode, the uninstaller runs in silent mode. Otherwise, the Configure License Server dialog box opens. To avoid the possibility of running the license server installer in silent mode, start it from a Command Prompt window. The nvidialsadmin utility provides options for administering the license server from the command line. Run the nvidialsadmin utility in a Windows or Linux command shell from the folder that contains the nvidialsadmin.
You must run the nvidialsadmin utility from the folder that contains the nvidialsadmin. If you try to run the utility from another folder by specifying the path to the utility either in the PATH variable or on the command line, the attempt fails and the following error message is displayed:. The following examples show the different ways of specifying the address of the license server in the base URL:.
Set the license server base URL for the nvidialsadmin utility in one of the following ways:. For details about the nvidialsadmin utility and its options, get help information for the utility by entering the following command in a command shell on the license server host:. When administrative security is enabled for the license server, the -authorize option with your credentials must be the first option that you specify in any nvidialsadmin command.
You can perform a status check to confirm that the license server is running correctly. This check tells you whether the license server is active and provides additional information, such as:. Run the nvidialsadmin utility with the -status option. Run the nvidialsadmin utility with the - features option. Run the nvidialsadmin utility with the -licenses and -verbose options. The license server uses system variables for items such as the location of the JRE libraries and executable files, the location of the trusted storage database, and the base URL for the nvidialsadmin utility.
The tasks explained in the following topics involve setting a Windows system variable:. The Path system variable must contain the path to the executable file of any software that you install on which the license server depends, for example, java. The installer may have already added this path for you. During troubleshooting of a license server failure after installation, upgrade, or migration of the JRE, you might need to delete a Windows user variable that was inadvertently set instead of a system variable.
During troubleshooting of a license server failure after installation, upgrade, or migration of the JRE, you might need to remove a path that was inadvertently added to the Path user variable instead of to the Path system variable.

High availability requires two license servers in a failover configuration: A primary license server, which is actively serving licenses to NVIDIA vGPU software clients A secondary license server, which acts as a backup for the primary license server Configuring two servers in a failover configuration increases availability because simultaneous failure of two servers is rare.
Note: To ensure that licenses in the enterprise remain continually available after failure of the primary license server, return the primary server to service within seven days of the failure. Furthermore, the remaining server becomes a single point of failure. Therefore, you should return the failed server to service as quickly as possible to restore high availability support for the license server.
Note: If you are configuring the license server for high availability, you must perform some tasks for both the primary license server and the secondary license server. For more information, see High Availability Requirements. Enabling Failover Support on the Primary and Secondary License Servers Register your license server, generate licenses, and download license files. Installing a License View available licenses. Reserving Licenses Move a license to a new server.
Before you install the license server software, ensure that the required software is already installed on each license server host machine that you are using: On Windows, you need ensure only that the Java runtime environment is installed. The Apache Tomcat server is included in the license server installer for Windows.
On Linux, you must ensure that both the Java runtime environment and the Apache Tomcat server are installed. Platform Requirements Before proceeding, ensure that you have a platform suitable for hosting the license server. Hardware and Software Requirements The hosting platform may be a physical machine, an on-premises virtual machine VM , or a VM on a supported cloud service.
At least 1 Gbyte of hard drive space is required. The hosting platform must run a supported operating system. On Window platforms,. NET Framework 4. NTP is recommended. The clocks on both servers must be accurate and synchronized. The same license configuration file must be installed on both servers.
This file is configured to include the Ethernet MAC addresses of both servers. Note: If you require high availability for the license server, you must install the license server both on the system that you will use as the primary license server and on the system that you will use as the secondary license server. Either a bit JRE is downloaded or the bitness of the downloaded version is determined from your browser, which might be bit even on a bit operating system.
Note: Copying an SSL certificate might corrupt it. Figure 2. License Agreements on Windows. Figure 3. Destination Folder Selection on Windows. Figure 4. Firewall Settings on Windows. Figure 5. Completed License Server Installation on Windows. It is not supported in earlier license server releases. The license server installer for earlier releases must be run in a graphical desktop environment. Installation in silent mode is not supported in any release. Note: Do not perform this task for upgrades from a bit license server to a bit license server.
Upgrade to this release of the license server by installing the license server software as explained in the following topics: Installing the License Server Software on Windows in Graphical Mode Installing the License Server Software on Windows in Console Mode. Note: If you are upgrading from an earlier bit license server that was bundled with Apache Tomcat 9.
Stop the Apache Tomcat service. In the Services application, context-click the Apache Tomcat 9. Uninstall the Apache Tomcat software. Context-click Apache Tomcat 9. When prompted, click Yes to confirm that you want to remove all files. Use the Services application to confirm that the Apache Tomcat service for the version that you installed is running. Copy the files fne.
Configure the Apache Tomcat service to start automatically on boot. In the Services application, context-click the Apache Tomcat service and choose Properties. Create the tomcat user to run the Apache Tomcat software. Create the user group tomcat for the tomcat user. Change the group that owns all the Apache Tomcat directories to tomcat. Load the service unit file that you created.
The home page of the default Tomcat web application should be displayed, as shown in Figure 6. Figure 6. Verifying the Apache Tomcat Installation. Note: Do not relocate the webapps folder, which is where Web applications are deployed on Apache Tomcat Server. If you relocate this folder, the installation of the license server software may fail.
Figure 7. License Agreements on Linux. Figure 8. Destination Folder Selection on Linux. Figure 9. Apache Tomcat Server Path on Linux. Figure Firewall Settings on Linux. Completed License Server Installation on Linux. Upgrade to this release of the license server by installing the license server software as explained in the following topics: Installing the License Server Software on Linux in Graphical Mode Installing the License Server Software on Linux in Console Mode.
Accessing the License Server Management Interface Access the license server management interface to verify that the license server is operating correctly or to manage licenses on the license server. License Server Login Page. Note: If administrative security is not enabled for the license server and you try to log in, the license server reports that the login failed. However, you can ignore the login failure and continue to use the license server management interface.
License Server Management Interface. Note: If you are configuring the license server for high availability, you will need the MAC address of both the primary license server and the secondary license server. Enabling Failover Support on the Primary and Secondary License Servers If you are configuring high availability for the license server, you must enable failover support on both the primary license server and on the secondary license server.
To ensure that you can verify the setup, set the log level to INFO before enabling failover support. Note: If you change a license server URI on an in-use setup, you must update the license settings of existing clients to use the new URI. On Linux, restart the nvidia-gridd service. Controlling Access to the License Server Management Interface For increased security, you can control access to the license server management interface by allowing access only to authorized users.
For general information about the nvidialsadmin command that you need to complete this task, see: Running the nvidialsadmin Utility Setting the License Server Base URL for the nvidialsadmin Utility Getting Help for the nvidialsadmin Utility. Enabling Administrative Security for the License Server When administrative security is enabled for the license server, any user attempting to administer the license server through the command line tool or the license server management interface must provide a set of authorization credentials.
To protect sensitive data that is being transmitted during administrative operations, use the HTTPS protocol for communications between the license server and its management interface when administrative security is enabled for the license server. If you no longer require administrative security to be enabled on the license server, set the property security.
Updated the property:security. Default License Server Administrative Credentials When the license server is started, the default administrator account is created and assigned super user role. The default credentials for the license server administrator account are as follows: User name: admin Password: Admin For increased security, reset the administrator password immediately after enabling administrative security for the license server.
License Server Password Requirements To help you set strong passwords, the license server enforces some requirements on the length and complexity of passwords. Resetting the Default Administrator Password for the License Server When the license server is started, the default administrator account is created and assigned super user role. Change the password of the admin user.
The password is case sensitive and must be a strong password that meets the requirements in License Server Password Requirements. Note: For clarity, required options for authenticating the administrator user and specifying the license server URL are omitted from this example. Creating a License Server User Account Perform this task in a command shell on the license server host.
This role is assigned by default. Modifying a License Server User Account You can modify the account of an existing license server user to change the password or the roles for the account. To leave the password unchanged, specify the user's existing password. To change the password, specify a new password. Deleting a License Server User Account Perform this task in a command shell on the license server host.
Only HTTP is supported for these connections. Request or create an SSL certificate for the license server. Run the following keytool command. When prompted for the key password, press Return to ensure that the key password and the keystore password match. Store the SSL certificate in the appropriate directory on the license server host.
On Windows, store the SSL certificate in the folder in which the license server is installed. Optional: To prevent the password from being stored in plain text in license server configuration files, obfuscate the password. This example obfuscates the password abracadabra. The license server is not blocked by a firewall.
You can obfuscate this with java -jar flexnetls. If the password is obfuscated, specify the entire obfuscated string, including the OBF: prefix, for example, OBF:1ri71v1r1v2n1ri71shq1ri71shs1ri71v1r1v2n1ri7. Note: To protect this password, ensure that the file that contains the password is appropriately secured. Specifically, limit access to the file that contains the password so that it can be read only by the user that the Tomcat process runs as and the administrator user on Windows or the root user on Linux.
To avoid the need to run the license server from a privileged account, use a port number greater than or equal to On Linux systems, access to ports below is restricted to processes that run with root user privileges. Do not include the path to this file. The Settings page opens. Note: Do not use this port number for connections between the license server and licensed clients. For connections between the license server and licensed clients, you must still use port Note: If the certificate chain contains an intermediate certificate, you must also save it in the same location.
Users now must access the license server management interface from a web browser through HTTPS on the specified port, for example, port You can also create multiple servers on the NVIDIA Licensing Portal and distribute your licenses across them as necessary, for example to group licenses functionally or geographically.
The role that this task requires depends on whether the license server is being created for an organization or a virtual group: For an organization, this task requires the Organization Administrator or the Organization User role. Downloading a License File Each license server that you create has a license file associated with it. The role that this task requires depends on whether the license file is being downloaded for an organization or a virtual group: For an organization, this task requires the Organization Administrator or the Organization User role.
Adding or Removing Licenses on a License Server Perform this task if you need to add or remove individual licenses for a specific product on the license server. The role that this task requires depends on whether the licenses are being managed for an organization or a virtual group: For an organization, this task requires the Organization Administrator or the Organization User role.
To ensure that the correct licenses are available on your license server host, download and install the license file after you add or remove licenses. Adding Licensed Products to a License Server You can add a new licensed product to a license server after the license server has been created.
The role that this task requires depends on whether the licensed products are being added for an organization or a virtual group: For an organization, this task requires the Organization Administrator or the Organization User role. Removing Licensed Products from a License Server Remove licensed products from a license server if they are no longer needed or in preparation for migrating them to a new server. The role that this task requires depends on whether the licensed products are being removed for an organization or a virtual group: For an organization, this task requires the Organization Administrator or the Organization User role.
If you removed licenses in preparation for migrating them to a new server, add them to the new server as explained in Adding Licensed Products to a License Server. Deleting a License Server The role that this task requires depends on whether the license server is being deleted for an organization or a virtual group: For an organization, this task requires the Organization Administrator or the Organization User role.
Organization Administrator An organization administrator has the highest level of visibility and access within an organization. Organization User An organization user has restricted visibility within an organization and can access only items that are at the organization level and that have not been assigned to a virtual group. An organization user is a contact that has been added to the organization as a base user.
Virtual Group Administrator A virtual group administrator has restricted visibility within an organization and can access items and manage contacts only in the virtual group to which the virtual group administrator is assigned.
A virtual group administrator is a contact that has been added to the virtual group as an admin user. Virtual Group User A virtual group user has no visibility within an organization and can view and access items only in a virtual group.
A virtual group user is a contact that has been added to the virtual group as a base user. Adding a Contact on the NVIDIA Licensing Portal The role that this task requires depends on whether the contact is being added to an organization or a virtual group: For an organization, this task requires the Organization Administrator role. For a virtual group, this task requires the Virtual Group Administrator role. If you added a contact who is already registered to a virtual group, the contact will be able the select the virtual group after next logging in.
If the contact is a new contact, an e-mail is sent to the contact at the e-mail address that you provided. Removing a Contact on the NVIDIA Licensing Portal The role that this task requires depends on whether the contact is being removed from an organization or a virtual group: For an organization, this task requires the Organization Administrator role.
Note: You cannot remove the only virtual group administrator from a virtual group. The Remove link for that contact is inactive and dimmed. A contact that is removed from an organization is removed from the list of registered contacts for the organization. A contact that was a member of multiple virtual groups when removed from a virtual group remains a member of the other virtual groups.
A contact that was a member of only the virtual group from which you removed the contact is returned to the organization with the organization user role. The role that this task requires depends on whether the contact whose role is being changed belongs to the organization or a virtual group: For the organization, this task requires the Organization Administrator role.
Note: You cannot change your own role. Managing Virtual Groups Virtual groups provide the means for segmenting your organization's entitlements into partitions. Creating a Virtual Group Ensure that the following prerequisites are met: Your organization contains at least one registered contact to whom you can assign the virtual group administrator role. No licensed products in any of the entitlements that you want to add to the group have been added to a license server.
Note: Any user with the Organization Administrator role loses that role and gains the role that you assign when added to the virtual group. Tip: To prevent the absence of a single user from denying you access to the virtual group, consider adding at least two virtual group administrators to the virtual group. After you create a virtual group, you can perform only the following operations on the virtual group: Deleting the virtual group Assigning an entitlement at the organization level to the virtual group Removing an entitlement from the virtual group and returning it to the organization Other operations on the virtual group require the virtual group administrator or virtual group user role.
Deleting a Virtual Group Delete a virtual group if it is no longer needed. Moving an Entitlement from your Organization to a Virtual Group Ensure that the following prerequisites are met: The entitlements that you want to add belong to the organization and not to a virtual group. Note: You cannot move an entitlement if any of its licensed products has been added to a license server.
The Move link for the entitlement is inactive and dimmed. Removing an Entitlement from a Virtual Group Remove an entitlement from a virtual group to return it to the organization either to make it available to users at the organization level or to transfer it to a different virtual group.
Note: You cannot remove an entitlement if any of its licensed products has been added to a license server or if it is the only entitlement in a group. The Remove link for the entitlement is inactive and dimmed. You can now move the entitlement that you removed to transfer it to a different virtual group as explained in Moving an Entitlement from your Organization to a Virtual Group.
Sample Business Scenario for Virtual Groups A common business scenario for virtual groups is a multinational corporation with subsidiaries in which licenses are managed centrally. Organization Administrators The organization administrators are responsible for setting up virtual groups and managing entitlements for the entire organization. Virtual Groups To simplify the allocation entitlements to the entity for which they were purchased, consider creating a virtual group for every subsidiary or geographic region, as appropriate.
Virtual Group Contacts To ensure redundancy at every level in your organization, designate at least two virtual group administrators for each virtual group. You manage the license server in a web browser through the license server management interface. Note: If you have configured high availability for the license server, you must install the license both on the primary license server and on the secondary license server. Selecting a License File. Successful Upload of a License File.
Verifying High Availability Setup of the License Server Messages in the license server log file about synchronization requests indicate the failover role of the given license server and its synchronization status. The primary server receives synchronization requests that the secondary server has initiated. For the primary server, search for the string Received sync request from the backup server. When the license server is operating, you can verify its high availability setup by confirming that the count of available licenses on the primary and the secondary servers changes as expected as clients acquire licenses from the server.
Viewing Information About Installed Licenses From the license server management interface, you can find out which licenses are installed on the server, view detailed information about individual licenses, and see how licensed clients are using the installed licenses. Viewing the Properties of All Installed Licensed Features By viewing licensed feature properties, you can see the licenses that are installed on the server and get detailed information about each installed license feature.
Viewing Licensed Feature Properties. Table 1. Version The version number associated with the feature. Count The number of licenses for the feature that are currently installed on the license server. Each concurrent user of a feature normally consumes one license. Available The number of licenses for the feature that are currently available to borrow from the server. This number decreases as users borrow licenses from the server, and increases as licenses are returned.
Expiry The date on which the right to use the licensed feature expires. If the licenses are perpetual use licenses, they have no expiration date. Perpetual licenses are indicated by permanent in place of an expiration date. Start Date The date on which the right to use the licensed feature starts. Viewing the Details of a Single Licensed Feature For each installed license feature, you can view detailed information about the feature.
Licensed Feature Usage Details. Viewing Information About All Borrowed Licenses By viewing information about all borrowed licenses, you can find out which licenses have been borrowed from the license server and are in use by a licensed client. Viewing License Usage. On the Licensed Clients page that opens, click the Client ID of the licensed client about which you want detailed information. The Client Details page opens to show detailed information about the licensed client.
Licensed Client Details. About the License Borrow Period At the end of the borrow period, typically multiple days, a borrowed license is automatically freed by the license server for use by other clients, and becomes unavailable on the licensed client that previously held it. Reserving Licenses Licenses are normally distributed to clients on a first-come, first-served basis. Creating License Reservations The license server management interface enables you to set up several new reservations and submit them to the license server in a single group.
Note: After creating a group of license reservations, you cannot use the management UI to delete individual reservations in the group or to add new reservations to the group. If you try to use the management UI to delete a single entry from the Reservation page, all entries on the page are deleted. Note: In an HA configuration, create identical license reservations on the primary license server and the secondary license server. To ensure that the license reservations are identical on both servers, you can export reservations from one server and import them into the other server as explained in Exporting and Importing License Reservations.
Adding a License Reservation. Submitting a Pending Reservation. After the reservations are submitted, the License Reservations page shows a list of currently stored reservations on the server. Listing Reservations. Deleting License Reservations If a client no longer requires a license that is reserved for it, delete the reservation to release the license for distribution to other clients.
Deleting a Reservation.
