tsql -C

Question

CENTOS 6.5 x86_64 WHM 11.42.1 unixODBC 2.2.14

freetds v0.91

我试图连接到远程MSSQL服务器但没有成功 - 也尝试连接不同的tds版本（4.2,7.0,7.1,8.0），但都给出了相同的结果。

使用相同的服务器名称，端口，用户名和密码，我可以使用Win7和SQL Server Management Studio通过我的桌面进行连接。

Telnet也失败了。

详细信息如下。如果您需要，请告诉我。所有帮助/建议表示赞赏。

Answer 1

我遇到了同样的问题并使用自定义端口解决了这个问题： port = XXXXX 在freetds.conf中应在SQL Server配置管理中配置此端口

SQL Server网络配置 - ＆gt; TCP / IP（已启用） - ＆gt; IP地址 - ＆gt; IPAll - ＆gt; TCP动态端口

https://msdn.microsoft.com/en-us/library/ms177440.aspx

Answer 2

我在VirtualBox中运行MS Windows。

因此，对于我从mac主机访问MS SQLServer，我必须：

在VirtualBox中添加端口转发条目＆gt;装置＆gt;网络＆gt;网络设置＆gt;高级
在MS控制面板中打开端口1444＆gt; Windows防火墙＆gt;高级设置＆gt;入境规则
在SQL Server配置管理器中启动SQL Server Browser＆gt; SQL 服务器服务
在SQL Server配置管理器中启用TCP＆gt;协议
在SQL Server配置管理器中为TCPAll设置TCP端口为1444＆gt;方案＆gt; TCP / IP＆gt;属性......

请注意，MS SQL Server配置为侦听端口1444。

Answer 3

我第一次使用Pymssql时看到了这个错误。我不得不打开TCP / IP作为本地安装SQL Server的网络协议之一。

Answer 4

在Cygwin 64上安装与FreeTDS连接到本地计算机上的SQL Server 2008数据库的类似解决方案。必须为MSSQLServer服务启用TCP / IP协议并重新启动要解析的服务。

freetds.log跟踪激活让我得到了解决方案（跟踪日志示例）：
