当使用tsql连接到127.0.0.1:1313时，tdspool输出仅表示“接受连接”，而不表示其他内容。freetds.log输出以下内容：

我也有类似的问题。将尽力帮助您解决您的问题。首先，确保/etc/freetds.conf包含有效的配置：

[global]
tds version = 4.2 
...
[myserver]
    host = <ip>
    port = 1433
    tds version = 4.2 < this is important

[全球]
tds版本=4.2
...
[myserver]
主机=
端口=1433
tds版本=4.2<这很重要

现在，/etc/tdspool.conf

 [sampool]
 user = [REDACTED]
 password = [REDACTED]
 database = [REDACTED]
 server = myserver < important
 port = 1313

[sampool]
用户=[已编辑]
密码=[已编辑]
数据库=[已编辑]
server=myserver<重要
端口=1313

然后TDPool应该可以正常启动。我的错误如下： 1.我认为pool.conf中的服务器是ip或服务器的域，而实际上这是对freetds.conf中服务器的引用 2.在freetds.conf中，我使用了错误（过高）的tds版本。Tdspool支持tds版本，最高版本为4.2，如其文档中所述

现在，如果您尝试通过tsql-S 172.0.0.1:1313进行连接，您仍然会永远得到“接受连接…”。但是，如果你这样做了

tsql -S 127.0.0.1:1313 -U <username> -P <password> -D <database>

tsql-s127.0.0.1:1313-U-P-D

您将通过tdspool连接并能够对您的sql server运行查询。

该软件存在错误。

我们去了官方的邮件列表，一字不差地问了这个问题。答案似乎是，如果不重写当前项目，就不会有一个

客户端库已经使用并经过了良好的测试，但池和服务器是情况真的不太好

tdspool的当前状态为。。。。它编译！我对此并不感到惊讶无法正确运行

也就是说它是开源的。欢迎提供任何帮助/建议/补丁

我们花了相当多的时间试图找出我们做错了什么，所以这是一种痛苦。虽然我希望创建/修改现有的SQL Server池，但我对FreeTDS（一个很棒的项目）附带如此不稳定的池感到失望

这对我来说不起作用。不管我做什么，我永远都会“接受连接…”。

tsql -S 127.0.0.1:1313 -U <username> -P <password> -D <database>
