should start "lmgrd -c license.dat" (sort of, I don't remember the exact command)
all EDA tools need lmgrd and each company's demon
I don't understand what you mean by point to the license?
you need to edit the license.dat first, configing the server port and the path of daemon program.
then run the following command
"lmgrd -c license.dat -l lic.log"
check the lic.log to see if the license server is up.
if there is no error, setting the LM_LICENSE_FILE to that <port_number>@<hostname>
