[Igor Korot <ikorot AT earthlink.net>]

Thank you for that clarification Brian.
Now, if I understood you correctly, all I need is an OSG, which will be a 
bridge between the Sybase 5.5 engine and FreeTDS in order to get the FreeTDS 
running with my version of SQL Anywhere 5.5.01, or at least try to configure 
it to see if it will work.
Now if this is correct, where I could find the OSG? I personally using the 
Gentoo Linux, so will try to check their packet database, but just in case I 
will not found it there, could you point me to the right direction.

Thank you in advance.

Igor, a couple of things.

The old Watcom database (which ASA is derived from) had a proprietary
protocol that it used.  When you say "have an ODBC driver" on Windows,
it is likely using this proprietary protocol, which FreeTDS does not
support.

Once Sybase bought Watcom, they started transitioning to the TDS
protocol and the T-SQL language.  ASA 5.5 was mostly T-SQL compliant,
but still used the proprietary protocol.  As a short term solution,
Sybase introduced OSG, which listens on for TDS connection on a port
you specify and translates that back to the proprietary protocol. 
Later versions went fully native TDS.

Now, regarding use of FreeTDS ODBC and the OSG.  It should be possible
to use the ODBC-only or DSN-less connection without configuring 
FreeTDS via the freetds.conf file.  However, your path of least
resistance will be to get tsql working first and then attempt the
unixODBC setup.  That way you'll know for certain that the server is
configured correctly, and what the settings are.

I do have an ODBC driver that connects me to the database, and it's native 
Sybase
ODBC driver. Now I do have a unixODBC installed on my Linux box. And as far 
as I
understand from the documentation on both, I have to have a connection from 
the 
FreeTDS in order to connect with ODBC. Is this true? Or ot's posible without 
working
FreeTDS connection?
