We received a new license file to replace the expiring license file for LS-DYNA. I followed the instructions in the new license file email to download and install the most up to date license server software.

I downloaded the license server "LSTC_LicenseManager_77918_ia32_redhat30.tgz" from the link https://www.lstc.com/download/lic/new_netnix_license that was listed in the new license file email that you had sent.

I also tried the FTP site at: https://ftp.lstc.com/user/license/License-Manager/. None of the license manager files there for RedHat have been updated since 2012...

I untar'd the contents of the "LSTC_LicenseManager_77918_ia32_redhat30.tgz" file and installed them in the working directory of the license server. These new binaries work fine with our existing license, but I get the same error when moving to the new license "Bad keys in the license file":

LSTC license server version 77918 started at Thu Feb 24 15:24:16 2022

Using configuration file /opt/lstc/server_data

ERROR: Invalid configuration file

ERROR: bad keys in the license file /opt/lstc/server_data

Any help would be appreciated.

Hello,
BAD KEYS error usually means 1. Something was changed in the "server_data" file that the license manager is unable to read. Note that new keys are issued for full IP range (000.000.000.000 255.255.255.255). Therefore, please do not modify/restrict the IP range, just leave it as ALLOW_RANGE:000.000.000.000 255.255.255.255 in "server_data" file
2. The license file contains JOBS and ADDED_CORES definitions. This requires using the most recent license manager (revision 111345). In the ftp link you provided, please go to "Job-License-Manager" under /user/license/ for the most recent license manager version.
Please also check if your email security or spam filter made any changes to the "server_data" file. We recently came across a few cases where license file was modified by spam filter.
