Introduction

This document is intended to help configure and install the NanoXplore License Manager Daemon (NXLMD) required to use NanoXplore tools.

Although it should work as expected on any recent 64 bit Linux or Windows operating system, the NanoXplore License Manager Daemon has been successfully tested on the following systems:

• RedHat Enterprise Linux 7 and 8

• Ubuntu 18.04 LTS and 20.04 LTS

• Windows Server

For any other distribution or platform, please contact the NanoXplore Support team at support@nanoxplore.com.

Package Description

The NXLMD-2.2-linux.tar.gz package contains the following directories:

The NXLMD-2.2-windows.zip package contains the following directories:

Installation

Linux

In this document we refer to the directory where the NXLMD files are installed as the installation directory.

Archive

• If the installation directory does not exist, create it using the command below:

  $> mkdir /opt/NanoXplore

To install the NanoXplore License Manager Daemon:

• Unpack NXLMD-2.2-linux.tar.gz file into the installation directory using the following command:

  $> tar xzvf NXLMD-2.2-linux.tar.gz -C /opt/NanoXplore

Linux Distribution Adaptation

The NanoXplore License Manager Daemon supports several Linux distributions, you must point to the right one when updating the symbolic links in the directory /opt/NanoXplore/NXLMD/2.2/bin.

• Please go to the bin directory and update all the existing links with the following commands (e.g. for RHEL 7):

  $> ln -sfn x86_64_RHEL_7/lmgrd lmgrd
  $> ln -sfn x86_64_RHEL_7/lmhostid lmhostid
  $> ln -sfn x86_64_RHEL_7/lmstat lmstat
  $> ln -sfn x86_64_RHEL_7/lmutil lmutil
  $> ln -sfn x86_64_RHEL_7/NXLMD NXLMD
  $> ln -sfn x86_64_RHEL_7/lmadmin lmadmin

Linking Libraries

The NanoXplore License Manager Daemon requires the library ld-lsb-x86-64.so.3 which might not be installed on Linux distributions.

• To do so, use the following command:

  $> ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3

Configuration of Variables

• When launching NanoXplore tools, the LM_LICENCE_FILE variable must be exported

• To avoid having to repeat this for every execution, you can to add it in the ~/.bashrc file with the following command:

  <port_number>@<machine_name>

  For instance:

  export LM_LICENCE_FILE=27000@localhost

Troubleshooting

LogFile Error

Linux

• If you use the nxlmd service, check the execution log file in the following directory :

  $> /var/log/NXLMD.log

• If you use the lmadmin service, check the execution log file in the following directory:

  $> /opt/NanoXplore/NXLMD/2.2/bin/lmadmin/logs/NXLMD.log

Windows

• Check the execution log files in:

  $> C:\NanoXplore\NXLMD\2.2\bin\lmadmin\logs

lmadmin Error (Linux)

Problem

The following message appears in the /opt/NanoXplore/NXLMD/2.2/bin/lmadmin/logs/web.log:

[alert] getpwuid: couldn't determine user name from uid 4294967295

Possible Cause

You may have launched lmadmin as root.

Workaround/Fix

Try to launch lmadmin as another user (dedicated lmadmin for example)

lmhostid Error (Linux)

Problem

The following message appears in the execution log file (example):

Wrong hostid on SERVER line for license file:

              ${MY_LICENSE_FILE}

SERVER lines says 08002780463d, hostid is (Can't get hostid of type 2 [])

Invalid hostid on SERVER line

With:

${MY_LICENSE_FILE} = ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/license.lic

Possible Cause

You probably have the wrong network interface (see previous sections for more information on how to change this)

Workaround/Fix

To check the hostid found by NXLMD without running the server, you can use the following command:

$> ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/lmhostid

• You must get a full hostid with ${HOSTID} not empty:

  The FlexNet host ID of this machine is "${HOSTID}"

lmstat Error (Linux)

Check the NanoXplore License Manager Daemon is running correctly using the following command:

$> ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/lmstat -a

GLIBC Problem (Linux)

Problem

If the following error message appears:

NXLMD: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by NXLMD)

Fix

Change the links in the ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin directory to your OS version.

For example:

lmgrd -> x86_64_UBUNTU_18/lmgrd
lmhostid -> x86_64_UBUNTU_18/lmhostid

lmstat -> x86_64_UBUNTU_18/lmstat

lmutil -> x86_64_UBUNTU_18/lmutil

NXLMD -> x86_64_UBUNTU_18/NXLMD

hostname Error(Linux)

Check your hostname is written in the file:

/etc/hosts.

Firewall Problem

Linux

Resolution

If you have a firewall set, add a specific rule for the lmgrd Port (27000 by default) and for the NXLMD Port

• You can manually specify the NXLMD Port in the License File, for example, to set the port to 27010:

  $> DAEMON NXLMD ${MY_BIN_DIRECTORY}/NXLMD PORT=27010

with ${MY_BIN_DIRECTORY} = ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/

Windows

If the Windows firewall is enabled, you must authorise lmadmin and lmgrd

• At the first launch of the server, Windows will ask you if you wish to authorise the services, otherwise, you must add them manually in the Firewall parameters.

“No such file or directory” Error (Linux)

Problem

If the following message appears when launching ‘journalctl –xe’ command:

$> lmadmin.service: Failed at step EXEC spawning /opt/NanoXplore/NXLMD/2.2/bin/lmadmin/lmadmin: No such file or directory

Reason

The ld-lsb-x86-64.so.3 file may be missing.

Workaround/Fix

• Run the following command:

  $> ls -l /lib64/ld-lsb-x86-64*

• If there is no result, run the following command:

  $> sudo ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3
