Freetds 連接SQL Server 錯誤：Unexpected EOF from the server

安裝好freetds 0.82後，用tsql連接數據庫，會出現以下錯誤：

locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Error 20017 (severity 9):
        Unexpected EOF from the server
        OS error 115, "Operation now in progress"
Error 20002 (severity 9):
        Adaptive Server connection failed

There was a problem connecting to the server 

程序連接也一樣，Unexpected EOF from the server。

查看網上的內容，可能與配置有關，於是修改配置文件freetds.conf,將對應的內容修改爲以下的值：

 tds version = 8.0

再次連接，成功連接到SQL Server。
