  Our server team has reported that our instance of Ansys License Manager (version 2023R1) on a linux server is using an outdated/vulnerable version of the TLS protocol. Is Ansys LM 2023R1 compatible with TLS 1.2? If not, is there a newer version of Ansys LM available which uses a secure version of TLS?

  See Section 9.3 of the ANSYS, Inc License Management Guide,
  Which show the Keyword below:
  Try the following:
  Logon to all of your ANSYS License Server machines
  Edit the file,
  Linux
  {ANSYSinstallationdirectory}/shared_files/licensing/ansyslmd.ini
  
  Windows
  C:\program files\Ansys Inc\Shared Files\Licensing\ansyslmd.ini
  Add the line,
  ANSYSLI_TLS_VERSION=1.2
  Stop then start again ANSYS licensing on the ANSYS license server machines

  George, thank you for your response. We do not see the expected ansyslmd.ini in the directory /shared_files/licensing/. Instead, we find:
  ansysli_data (directory)
  ansysli_server.log
  ansys_pid
  gatherdiagnostics
  init_ansysli
  init_ansyslm_tomcat
  language (directory)
  lic_admin (directory)
  license_files (directory)
  license.log
  license.log_07282023
  linx64 (directory)
  logs_backup (directory)
  prodord (directory)
  start_ansysli
  start_lmcenter
  stop_ansysli
  stop_lmcenter
  tools (directory)
  
  We have Ansys 2023r1 on RedHat 7.

  Hi,
  You can manually create the ansyslmd.ini file under the /shared_files/licensing/ directory.
  This is just a text file.
  Then add the following line to it:
  ANSYSLI_TLS_VERSION=1.2
  
  Then restart the License Manager.
