informix@codsrv222:/opt/ids10.uc3>finderr -956
-956 Client client-name is not in /etc/hosts.equiv on the remote host.
This operation cannot be completed because the specified remote computer
does not recognize the name of the client computer (the local host,
whose name the hostname command returns). Client names are normally
recorded in the configuration file /etc/hosts.equiv. The rhosts file on
the remote computer might also need modification. For more information
on these files and the relation between them, try man rhosts on a UNIX
system. See the remote host administrator to ensure that the client
host name is specified in /etc/hosts.equiv file for the remote host.
