The license manager daemons use TCP/IP ports to manage the license requests on the network. The TCP/IP port number is identified on the SERVER line of the license file.
We have defined the default port number to be 27005 for both UNIX and Windows NT. The port number, however, is changeable. If another FLEXlm application on your system is already using the TCP/IP port 27005, there will be a conflict, and when the license manager is started you will get one of the following messages:
license manager: socket bind: Permission denied
license manager: socket bind: Address in use
The license file can be edited and another TCP/IP port number can be selected for the license manager. GLOBEtrotter owns port number 27000 through 27009. We strongly recommend that you use a port number within this range. We now assign port 27005 by default, which significantly reduces port conflict with other software vendors.
The TCP/IP port number for the license manager can be set in the /etc/services file on the license server. If the network is running yellow pages, then edit the yellow pages master file /etc/services.
Go to the following location to change TCP/IP information:
%SystemRoot%\system32\drivers\etc\services
Add the following line to /etc/services:
license 27005/tcp
This will reserve port number 27005 as the license manager port.
Since the license manager uses Ethernet to function, TCP/IP must be enabled even on a standalone system.
