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.
This message appears in versions prior to Version 6.0.


-956 Client client-name or user is not trusted by the database server.

The desired database server does not consider the client computer or
your user ID trusted. Ask the system administrator to include the
client computer as a trusted host and/or your user id as a trusted user
in the /etc/hosts.equiv file on the server computer or in the .rhosts
file in your home directory on the server computer. See the UNIX manual
pages on HOSTS.EQUIV(5) for more information.

Alternatively, you can explicitly specify your user name and password
in the USER clause of a CONNECT statement or in the .netrc file in your
home directory on the client computer. See the IBM Informix Guide to SQL:
Syntax for information on the CONNECT statement, and the UNIX manual
pages regarding NETRC(5) for information on the .netrc file. This
message appears with Version 6.0 and later.

Проще говоря, попробуй добавить запись вида hostname username на сервере в /etc/hosts.equiv (на виндах он лежит в %WINNT%/system32/drivers/etc)
