Keysight CAE license management kit 2025.10 on Linux

Keysight CAE license management kit 2025.12 on Linux x86_64

(for RedHat 8 & compliant Linux distributions)

Description of this toolkit:

FlexNet Publisher (FNP) pack 11.19.9.0

Licensing Server toolkit, composed of:

lmgrd
lmutil
pam_lmd
lmobfslog
enduser.pdf

Starting a license server in command line: lmgrd -c my-license-file.lic -l my-debug-log-file.log
Have a look at FlexNet Publisher License Administration Guide delivered in this toolkit (page 113).

Custom Vendor Utility generator : GetESIVDH.exe

This utility is used by KCAEGetHostID.sh script. There is no need to use it directly.

FNP Licensing Service utility for Virtual Machine support, composed of

install_fnp.sh
FNPLicensingService/FNPLicensingService

Starting this service as root (using delivered script install_fnp.sh to facilitate the usage) is mandatory when using Virtual Machines as license server.
This service is required by FNP Licensing toolkit in order to get VM_UUID Host ID type on Virtual Machines.
This service is required too when starting the license server daemon on Virtual Machines with this Host ID type.

Script delivered by Keysight : KCAEGetHostID.sh

Running KCAEGetHostID.sh script will get the required system information that will be used for the generation of license file.
The resulting text file KCAEGetHostIDComputerName_date.txt has to be sent to Keysight for license generation & support.

Utility to obfuscate the usernames in the logs : lmobfslog

The lmobfslog utility processes the debug log file to generate the obfuscated usernames. Usage: lmobfslog [-i debug_log] [-o new_debug_log] <-rmarker>
Note: lmobfslog works only if the debug log has been produced with OBF_ADDMARK keyword. The lmobfslog utility can then generate obfuscated usernames in a new debug log.
To do, add the line DEBUGLOG "debug_log_path" OBF_ADDMARK in options file pam_lmd.opt.
see pages 166 and 193 in FlexNet Publisher License Administration Guide delivered in this toolkit

Script delivered by Keysight : esiflexdiag

esiflexdiag parses the content of a license file (given as argument) and displays lots of relevant details from a running license server.

Example of KCAEGetHostID outputs:

Here some example of outputs when running script ./KCAEGetHostID.sh to get system details:

1. When machine type is Physical:

$ ./KCAEGetHostID.sh

Keysight CAE details for this host:
Hostname.........: dc1ser0029.vbr.is.keysight.com
Chassis Type.....: Running on Physical Platform
IPv4 Address.....: 10.25.88.194
Time zone........: Europe/Paris (CEST, +0200)
Local time.......: Wed 2026-03-12 12:15:04 CEST
Possible HostIDs.:
   ESIVDH=BH6NSQNuA3f1dh96Tlab6DA ESIVDH=RO0iW4-fTd1fHgdGS3XyOCA
   === or ===
   "PHY_ETHER=2cea7fe40a15 PHY_ETHER=2cea7fe40a18 PHY_ETHER=2cea7fe40a18 PHY_ETHER=2cea7fe40a18"

One of the Ethernet Address or ESIVDH Host ID can be used for setting up the license server.

2. When machine type is Virtual:

2.1 At first execution, this can give something like:

$ ./KCAEGetHostID.sh

FNPLicensingService: The licensing service is not present on the system.

Keysight CAE details for this host:
Hostname.........: dc1vse0135.bbn.is.keysight.com
Chassis Type.....: Running on Virtual Platform
IPv4 Address.....: 10.25.89.52
Time zone........: Europe/Paris (CEST, +0200)
Local time.......: Thu 2026-03-12 12:32:44 CEST
Possible HostIDs.:

   === or ===
   "005056b7799e 005056b7be09"

Sometimes VM_UUID could not be determined, following message will be displayed:

ERROR: VM_UUID Host ID type could not be determined
Result of command: /nishome/licensing/v11.19.9.0/Linux-rhel8/lmutil lmhostid -ptype VM

===============================================================================
lmutil - Copyright (c) 1989-2025 Flexera. All Rights Reserved.
The FlexNet host ID of this machine is ""
lmhostid: The FlexNet Licensing Service is not installed. (-213,14703)
===============================================================================

INFO: Ensure that FlexNet Licensing Service is well started.
This is required to obtain VM_UUID Host ID type on Virtual Platforms.

Check first availability of FUSE system packages: fuse fuse-devel fuse-libs gvfs-fuse

Then install FlexNet Licensing Service by running following script as root:
cd /nishome/licensing/v11.19.9.0/Linux-rhel8
sudo ./install_fnp.sh --cert

There is a special line about FNPLicensingService availability.
It must be installed/configured as root (or with sudo) in order to get VM_UUID Host ID type because we are on a Virtual Machine in that example.

2.2 After checking (installing) FUSE packages and executing given command line (as root), we obtain this output:

$ ./KCAEGetHostID.sh

   === or ===
   VM_UUID=04313742-7571-2785-0bd7-245dd076dcef

Now VM_UUID Host ID is correctly displayed and can be used for setting up the license server.
