On the SERVER line this_host can be changed to the ip address of the license server and HOSTNAME should be the same as the the result returned by [hostname or uname -n] in the terminal. the third argument on the server line is used for the port which can be set to the desired port, or else it will be set to a default value in the range of 27000 to 27009. you can also add the PRIMARY_IS_MASTER and HEARTBEAT_INTERVAL. These options are used with license servers configured for three-server redundancy to indicate how master control is transferred between the primary and secondary servers.
