sql-server – 使用FreeTDS连接到MS SQL Server：错误20002：“A

我正在尝试使用FreeTDS从 Linux服务器(RHEL v7)连接到运行MS SQL Server 2014的单独服务器.但是,当尝试使用tsql连接时,我收到以下错误(错误消息因我是否包含用户名而异密码)：

$tsql -S MYSERVER
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Error 20002 (severity 9):
        Adaptive Server connection failed
There was a problem connecting to the server
$tsql -S MYSERVER -U myusername -P mypassword
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
Error 20002 (severity 9):
        Adaptive Server connection failed
There was a problem connecting to the server

另外,运行tsql -LH不会输出：

$tsql -LH MYSERVER
$

我不相信问题出在防火墙或SQL Server端的任何其他问题上,因为：

>我能够telnet到服务器：

$telnet my.server.address 1433
Trying 11.22.33.444...
Connected to my.server.address.

>并且,我可以通过ODBC数据源管理器实用程序从(Windows)笔记本电脑通过ODBC成功连接到SQL Server.

我的/etc/freetds.conf的内容：

[global]
  tds version = 7.0
; tds version = 4.2
...
[MYSERVER]
  host = my.server.address
  port = 1433
  tds version = 7.0

运行tsql -S MYSERVER后TDSDUMP日志文件的内容：
