For support of Microsoft SQL Server 7.0, 2000, and 2005, the driver requires the SQL Server 7.0 versions of Net-Library DLL files, which are installed when you install the SQL Server Legacy Wire Protocol driver. The driver communicates with network software through the SQL Server Net-Library interface.
To use the SQL Server Legacy Wire Protocol driver on UNIX and Linux, you must have TCP/IP configured on both the UNIX and Linux clients and the Windows server on which the Microsoft SQL Server database resides. The UNIX and Linux SQL Server TCP/IP network client library is built into the SQL Server Legacy Wire Protocol driver on UNIX and Linux.
