No, it means your application (the Client)
attempted to connect to a Firebird server in a
Windows environment and the request failed
because the Windows host (Wine in this case)
could not establish a route to this Windows server.

This is a Windows file specification. You have
Firebird 1.5 running on Ubuntu. Your database
has to be in a Linux directory in the physical
filesystem and you use a Linux file specification to connect.

Suppose you move the database to a directory
named /base_de_dados, then your connection request would be:

localhost:/base_de_dados/dbrequisicao.fdb

Only TCP/IP (including local loopback, i.e. via
localhost) is possible for this
environment. "Local protocol" is something quite
different on Linux and won't work for any
external client. Your Wine server is running
your application as an external client.

The Quick Start Guide for Firebird. If it is
missing from the Ubuntu installation, you can
download it from the Firebird website, via the Fb
1.5 download page or the Documentation Index.
