commands failure

Hello sir I'me testing FRED. With administrative interface I've create a registrar I can search it but when I verify the table registrar in databse I don't see it. Why ? When I execute creation commands, after typing command conection "fred-client -h nic -p 22353 -u REG-FRED_A -w passwd, in console" It sent after I fill up fields : Interactive input completed. [Press Enter] I press ENTER  It sent back error like : You are not connected. ERROR: Command data XML document failed to validate. More details in verbose 2 or higher. If I open ./nofred/named/cron.log there is line error:        File "/home/nic/root/lib/python2.5/site-packages/pyfred/zone.py",       line 174, in getObject      raise ZoneException("Is nameservice running? (%s)" % e)       pyfred.zone.ZoneException: Is nameservice running?      (CORBA.TRANSIENT(omniORB.TRANSIENT_ConnectFailed, CORBA.COMPLETED_NO)) T  Is this the problem ? have I to modify some configuration files ? how to connect for executing commands (creating contact, registrar, domaine.... etc) ? thank you
