can't access Quartus Pro floating license from Linux

Hi there,

Currently I have two Quartus Pro 18.1 licenses floating on a server. I can access it from my Win7 workstation compiling Stratix 10 designs no problem. Recently I installed Quartus Pro 18.1 on a Red Hat Enterprise 7 Linux server and tried to access the same floating licenses to no avail. In Linux command line using lmutil tool I can see the license, but when I launched a compile, Quartus started to analyze files but just seconds later it outputed something like this

Info: Analyzing source files

Error (19286): No license for family Stratix 10

Error: Flow failed: ERROR: Current design not found

Warning: Failed to write report

Error: Quartus Prime Synthesis was unsuccessful. 2 errors, 1 warning

It is the same design I used on the Win7 machine. The "Current design not found" is probably not real. So it is likely because of the license. In Linux I did not use GUI, just command line to compile

quartus_sh --flow compile project_name

I had LM_LICENSE_FILE set to point to the license server.

Any help is greatly appreciated.

Thanks.

Jun.
