Default:
>> kalach@kalach1:~/gpsd$ export GPSD_HOME=/home/kalach/gpsd/
>> kalach@kalach1:~/gpsd$ ./gpsd -N gpsd://192.168.10.10

stager@StagerServer:~/gpsd$ pstree -paul 16077
python,16077,stager ./gpsfake -v -c 1 test/daemon/ais-nmea.log
  └─gpsd,16078 -b -N -S 2947 -F /tmp/gpsfake-16077.sock

stager@StagerServer:~/gpsd$ netstat -a | grep gpsd
