Also, check status: I'm not sure: sudo apt-get reconfigure firebird2.5-super(enable service). As mangakissa said, see the link, how to set configuration(firebird.conf) p.s.check permission! sudo chmod 777 -R /your/folder/with_fdb ---------------------------------------------------------------------- exdatis · 2014-07-01 05:13 Quote from: exdatis on June 30, 2014, 01:43:53 pmI'm not sure: sudo apt-get reconfigure firebird2.5-super(enable service).
