Failover Group Settings
Failover eliminates the risk of single point of failure. It requires at least two Userful hosts in the same subnet. In the event of failure, backup host can take over the stations that were assigned to the failed host. Please refer to Failover page for detailed information.
With Userful™, Licensing is quick and easily managed through the Control Center. The unlicensed version of Userful™ is fully functional, but will display a brief registration reminder on all attached displays every 20 minutes or so. To enable the full version, you need a valid license for each display.
Getting License Key Online
To get your host PC/server licensed online, goto"Manage Licensing" link under System Operations.
If you already have an activation code:
- Enter the Activation Code in the first box.
- Enter the maximum number of stations to be used in the second box.
- Press "Download and Install License" button to get the license key.
Note: The activation code is tied to a certain number of stations. The number of stations entered cannot exceed the number specified when activation code was created.
To get the "Activation Code", click "Get Activation Code" and submit the form.
You will need an active Internet connection to automatically install the license key or to submit the request for activation code.
Your web browser submits the basic system information to the license server as a part of the activation process. This information includes MAC address, Userful™ version and other hardware information.
The license key file(s) are installed automatically and take effect without rebooting the system.
Installing a License Key from a File
A Internet connection is required to use the activation code to install your license. If there is no Internet connection, email the MAC address or System ID of the host PC/server you need to license along with your activation code to the Userful representative. They will generate a license key and send it to you as an attachment.
To install a license key from a file:
- Copy the file to the desktop of the system to be licensed or mount a USB flash drive containing the license key file.
- From the starting screen of the Licensing section, click on the button marked "Manually Install License File" under System Operations > Manage Licensing > Replace License.
- Click on the "Browse" button and navigate through the file system to the directory where the license key is saved. Select the license key file and choose "Open".
- Click on the "Upload License File" button. The license key file is installed automatically and takes effect after rebooting the system.
Increasing the Maximum Number of Stations on a License
If your contract allows, it is possible to increase the maximum number of stations connected to a given host PC/server without replacing the license. To do this, click on the "Increase Stations" link under System Operations > Manage Licensing
If desired, backup the existing license by clicking the "Backup your current license file” link in the dialogue that appears.
Enter the “Activation Code” and the new "Maximum Number of Stations". Click on the "Request Increase from License Server" button to complete the operation.
Please Note: The new maximum number of stations entered must be greater than the current maximum.
The "License Details" will now reflect the increased Maximum Number of Stations.
Backing up a License File
- To back up a license file, go to System Operations > Manage Licensing and click the "Download/Backup current license".
- This will open a dialogue box asking to confirm the file-saving operation. Click "Save" to save a copy of the license file with a ".bak" file extension in the /etc/userful/license/ directory.
Replacing an Existing License
Sometimes it may be necessary to replace a license on a working system; for example, to add more stations to the license. Contact your Userful representative if you have any questions about obtaining a replacement license.
To replace a license, go to System Operations > Manage Licensing and click the "Replace License" button. Follow the instructions to either get a license through the Internet (if you have an activation code) or install a license file manually.
Note: License persist when product is upgraded to a newer version. That is, if you already have a license for a version of Userful™, you can update your system to the newest available version without obtaining a new license as long as you have an active maintenance and support contract.
Change Admin Password
User can change admin(root) password using this link. To do so:
- From the "Control Center" Navigation Panel, go to System Operations
- Click on "Change Admin Password" link
- A window will popup, enter Current Password, New Password and Repeat Password
- Click "OK" button
The change will take effect immediately without system reboot.
User can change Hostname using this link.
- Click on Control Center > System Operations > Change Hostname link
- A window will popup, enter New Hostname
- Click "OK" button
This will restart all connected zero-clients and control center, the change will take effect after system reboot.
Nvidia Offload Card
Userful™ supports Nvidia GPU offloading that enables you to create a high quality video wall with better content synchronization. For more details, visit Nvidia Support page.
Automatic Nightly Shutdown
To conserve power and to ensure proper shutdown of host PC/server, you can enable automatic shutdown process. To enable this:
- Click "Automatic Nightly Shutdown (Host)" and check the "Automatically Shutdown the host PC/server" checkbox
- Enter the time in (HH/MM) format
Note: Warning message will pop 5 minutes before the scheduled time to notify all users to save their work.
Control Center also provides instructions to do automatic power-on using BIOS. This feature is particularly helpful if it is hard to access host PC/server physically. Click on the " change BIOS settings" link and follow the instructions.
Userful has added DPMS (Display Power Management Signaling) support for network zero-client devices. DPMS is a standard used to save power and maximize the useful life of display devices including projectors. To enable DPMS functionality for zero-client stations:
- Goto Control Center > System Operations, open “DPMS Settings” window.
- Mark "Turn off inactive displays after” checkbox and select the time interval from the drop-down menu and hit “OK” button.
All connected displays including host PC/server's display will go offline at the specified time.
Reboot and Shut Down System
Host PC/server can be reboot or Shut down using the "Reboot System" and "Shut Down System" buttons respectively.
Clicking on each button will bring up a confirmation dialog and once confirmed appropriate action will be performed.
Network Settings section of System Operations displays following information of Network Interface Card:
- Interface Name
- Link Status
- IP Address
- Lease Time
- Proxy Settings
"Edit" button located to the right of the IP address opens the network settings configuration box for the host PC/server. By default, host PC/server automatically retrieve its network settings and IP Address from router or DHCP server. It is possible to override this setting and manually configure the network.
The Control Center uses the Internet to contact the Userful licensing server. If the computer system is behind a proxy server, administrators must set a proxy address within the Control Center to allow the host PC/server to communicate with the licensing server in order to retrieve licenses.
To configure proxy settings, go to System Operations > Network Settings > Proxy Settings under Control Center. Select the "Manual Proxy Configuration" option and enter the host PC/server proxy address and the TCP port and click "OK".
Userful team is continually working to improve product stability and feature set for upcoming version releases. Occasionally, Userful may release important updates between official software version releases.
To check for such updates, goto Control Center > System Operations > System Updates > Check for Updates.
Please Note: An active Internet connection and a valid Support and Maintenance contract is required to access the software updates.
Userful provides the ability to install Third-party add-on packages directly through Control Center. To access this functionality, click "Check for Available Add-ons" link under "Third-party Add-ons".
Simply, select the package and hit "Apply" to start the installation process. Changes will take place without the system reboot.
Date and Time
Host PC/Server's date and time zone can be changed by clicking on “Change” link. User can edit date and time manually by entering values in the text box provided or can set it to "Automatic".
System and keyboard language are displayed at the end of System Operations screen. In order to change the language click “Change” link and select System and keyboard language from the drop-down. The changes will take effect only after the reboot.
