I know of no difference in functionality between DAEMON and VENDOR. If you want to change it, you can.
FlexNet has been somewhat inconsistent with the behavior of the format of this line over many releases. You should use five fields to ensure consistency from release to release, including an options file or stub options file. You can change it to VENDOR like so:
VENDOR mgcld <path_to_mgcld> OPTIONS=<path_to_options_file> PORT=<port_number>
Thank you for your response.
From old manual (End Users Guide VERSION 9.2 JULY 2003, Macrovision)
FLEXLM VERSION NOTES
• vendor_daemon_path required in pre-v6.0 vendor daemon.
• options_file_path required in pre-v6.0 vendor daemon.
• VENDOR lines are known as DAEMON lines in the pre-v6.0 lmgrd and
DAEMON sampled /etc/sampled \
• The options= keyword introduced in the v5.0 vendor daemon.
Modern manual do net mention DAEMON lines at all.
Changing to VENDOR is on a list of proposed changes to our license file format. However, we don't yet have a timeline for those changes. Since you can manually change it from DAEMON to VENDOR without any detriment to mgcld, I recommend that as a solution for now.
I am working with Ken Foster on this. I tries a bunch of different things including replacing keyword. Nothing worked so far, but I remain optimistic.
