Our server team has reported that our instance of Ansys License Manager (version 2023R1) on a linux server is using an outdated/vulnerable version of the TLS protocol.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?

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.
