This reports which license features have been found, but doesn't do
anything with them. You need to decide which features you'd like to
keep, which names they should receive and perhaps decide on some limits.
This information goes into your qlicserver.config file.
The format of this file is documented here:
After you've made your changes. Try re-running "./qlicserver -i" and see
what you get. You should now see that your features are visible and
correctly remapped and that they aren't just "newly discovered".
Note that you can also add in your LM_LICENSE_FILE value directly into
the same configuration file.

See comment above. Note that './qlicserver -c' doesn't use any values
from a license server query at all. It simply emits your config
information in an appropriate format for creating complexes.

No. This is neither possible nor desirable. There are a myriad of
specialized names for addressing particular FLEXLM daemons and there is
no simple, consistent and predictable means of addressing them.
Internally the license query uses "lmutil lmstat -c xxx" and thus
bypasses all of the WHATEVER_LIC_FILE environment variables anyhow.
The solution for you is to add all the license servers to be addressed
into the LM_LICENSE_FILE config parameter. It is only a small amount of
typing to do once, but results in a more reliable configuration.
BTW: I might drop the default hard-wired configuration if it causes too
much confusion. The basic idea is/was to provide a means of defining a
configuration without any reliance on external files and simultaneously
provide a base configuration that could be augmented or replaced by the
external configuration information.
