  1. Citrix MPS 3.0Licensing Douglas A. Brown President dbrown@dabcc.com

  2. Agenda • Introduction to Citrix Licensing • About FlexLm licensing • Components of a license server • Daemons & Ports • License File • Tools

  3. What is FLEXlm Licensing • A license manager that manages floating software licenses • An SDK licensed from MacroVision and integrated into Presentation Server • Includes the following components: • The License Server • Libraries embedded in MPS • Command Line Utilities

  4. What is a License Server • Four Components: • License Manager Daemon (LMGRD.exe) • Vendor Daemon (CITRIX.exe) • License file • Utilities

  5. New Features of MPS Licensing • Enterprise, Advanced and Standard edition will replace product codes and XPs. XPa and XPe • Product edition changes on the Presentation Server will require a reboot to inform all the components of the new license status

  6. Software Requirements • Operating Systems • License server is only support on Windows 2000 and Windows 2003 servers • Unix Platforms will not be support until the next release of MFU • MPS 3.0 and Conferencing Manager 3.0 are the only Citrix products that support the new licensing model.

  7. Software Prerequisites • Prerequisites: • Microsoft .NET Framework Version 1.1 or later • Java Runtime Environment (JRE) version 1.4.1_02 or later • Visual Studios J# .NET Version 1.1 or later • ASP.NET (A Windows component) • Setup will automatically install any software prerequisites • Only is using Autorun installation

  8. Impact on Hardware • CPU usage will increase with: • Single treaded application so no need for multiple CPUs • Large amounts of check in/outs (hundreds as second) • Many products exchanging heartbeat messages with the license server • Hard Drive space will be affected: • Depending on the size of the report log, more activity bigger the log • Network: • Transactions use less than 1KB of bandwidth • Memory usage increases: • Depending on size of license file, options file, and concurrent users

  9. MPS Initial Grace Period • 96 hours • If you run over this date then: • 1 administator can connect • 2 users can connect • Hotfix available to extend this limit to 60 days

  10. License File • Should be two *.lic files located in “Program Files\Citrix\Licensing\MyFiles” • Citrix_startup.lic • ????.lic (licensing file downloaded from mycitrix.com • License File Contains • Hostname of license server • Vendor daemon name • At least one line of INCREMENT or FEATURE data • Particular changes to the license file may corrupt the digital signature • Can change license port • Can’t change hostname or anything else

  11. Citrix_Startup.lic • Installed by default • Dummy license file that services the following purposes: • Keeps the heartbeat alive between the MPS server and the license server • Show what MPS servers are connected to the license server • Has out of the box grace period information

  12. ????.lic (License for mycitrix.com) • Obtained from mycitrix.com • MPS acquires connection license from this file when users connect • One license per client • License released after all client connections to all MPS servers are closed • Name of the file does not matter

  13. How Does it Work? • MPS licensing policy resides in the wsxica.dll which is loaded by termsrv.exe • Wsxica communicates with the license server for license check in/out • License check in/out occurs during log in/out • License server and MPS exchange a heartbeat message every 120 second • Citrix licensing is enforced on RDP connections

  14. License Sharing Across Servers • There can be more than one license server • MPS server makes requests to the license server for each unique client connection • All client connections from the same client id share a single product license

  15. License Manager Daemon (LMGRD) • Handles the initial contact with the MetaFrame Access Suite product • Starts the Citrix vendor daemon and passes connections to it • Uses default TCP port 27000 • The default port can be changed by modifying the license file on the license server (CTX103008)

  16. Citrix Vendor Daemon • Process is called Citrix.exe • Job is to grant, deny, and keep track of licenses for Access Suite products • Writes to report log and the debug log • Default TCP port is chosen by the operating system when LS is rebooted or the CitrixLicensing service is restarted • Sites with firewalls that require a static IP Port can specify a hard coded port through CTX103356

  17. Date Based Versioning • Increment or Permanent Licensing • SA date: “version” of license. 1 year from time the license file was created • Burn Date: Date product released • If SA date is earlier the Burn date product will not function

  18. License Management Console • Is optional but cannot be installed on a separate server from the license server • Functions: • Allows creation of reports logs the detail past license usage • Assign user permissions and roles for access to the LMC • Display license inventory, current usage, set the thresholds for warnings and alerts

  19. ToolsVerify Check out Data: • Lmstat –a to verify checkout data: • Shows the data the license server has recorded for each connection. • Also shows: • The product that the user has check out a license for • The client machine that check out the license • The checkout data • The version of the license • License Server name and port • Date license was checked out

  20. More Command Line Tools • Lmdiag –c “path to the license file” • Helps diagnose whether license can be checked out • Lmreread – c “path to the license file” • Reloads the license file in the memory without restarting the service” • LmhostID –hostname • Displays the host name of the license server

  21. More Command Line Tools • Netstat –a on the License server • Shows if the correct ports are listening (LMGRD) • Shows all MPS server connected to a license Server

  22. License Error Messages • You can receive error messages for licensing in the following places: • Event Log of the MPS Server • Pop-up messages on the license server • Pop-up messages on the client device • Verify license is installed and services are running • Restart IIS • Restart all services • Verify hostname to license file host name

  23. Gotchas • When a port is changed in the license file all future license files will need to be modified to reflect the port number • User connecting to MPS server of different editions will take multiple license one for each edition • If clock on MPS or LS is modified 24 hours back licensing will not function and server will need to be rebuilt

  24. “A Splendid Time is Guaranteed for All!”
