trying to stop firebird I am getting following:

[root@fedora_home bin]# ./fbmgr -shut
Unable to complete network request to host "localhost".
-Failed to locate host machine.
-The specified name was not found in the hosts file or Domain Name
Services.
can not attach to server


in the firebird.log I are following lines:
fedora_home (Client) Thu Jun 1 02:01:29 2006
INET/INET_connect: gethostbyname failed, error code = 1


I am working with Firebird 1.5 SS on Fedora Core4 (2.6.14)

Thanks for your comments
