Hello sir  I have read in the FRED archives for starting FRED servers I have to type the command: nic@nicGest:~$ /etc/init.d/fred-server start Starting FRED central registry CORBA servers....  And after  I verify if servers were started : nic@nicGest:~$ /etc/init.d/fred-server status fred-pyfred is stopped fred-rifd is stopped fred-pifd is stopped fred-adifd is stopped     I don't know why servers don't start ?    Then I thing that this is the reason of connection errors when I type command to start     fred-client :       nic@nicGest:~/ etc/fred/fred-client.conf         Connecting to localhost, port 22351 ...         ERROR: I cannot connect to the server localhost.         Connection socket.error: (111, 'Connection refused') (localhost:22351)         How to start the FRED servers ?         How to solve connection errors ?
