FreeTDS:不连接

Question

早上!

我在运行命令时遇到问题：

tsql -S "servername" - U "user" -P "password"

我从命令中得到了as响应：

There was a problem connecting to the server

我正在尝试连接到MS SQL服务器。我已经检查了文档，但我还没有找到解决这个问题的方法。

我的freetds.conf是：

[global]
    # TDS protocol version
    tds version = 4.2

    # Whether to write a TDSDUMP file for diagnostic purposes
    # (setting this to /tmp is insecure on a multi-user system)
    dump file = /tmp/freetds.log
    debug flags = 0xffff

    # Command and connection timeouts
    timeout = 10
    connect timeout = 10

    # If you get out-of-memory errors, it may mean that your client
    # is trying to allocate a huge buffer for a TEXT field.
    # Try setting 'text size' to a more reasonable limit
    text size = 64512

# A typical Sybase server
[egServer50]
    host = symachine.domain.com
        port = 5000
        tds version = 5.0

# A typical Microsoft server
[egServer70]
    host = ntmachine.domain.com
        port = 1433
        tds version = 7.0

[SRVBD1] 
        host = 10.7.1.7          
        instance = SQL2008
        port = 1434
        tds version = 5.0

检查FreeTDS日志文件时，我注意到以下错误：

有人知道怎么解决这个问题吗？

谢谢!

Answer 1

如果您的配置是使用tds version = 5.0，则SQL Server2008不支持它。你可以试试tds version = 7.1吗？另外，您确定它在端口1434上而不是1433 (默认端口)上吗？

如果这不起作用，我会在解决问题的过程中修改这个答案，但这是我看到的第一个答案。
