Question

我正在使用tsql来确认与ms sql server实例的连接：

tsql -S "66.239.210.201\[instance name],1481" -U [username]
Password: [password]

输出：

locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
[counts from 1 to 16]
16There was a problem connecting to the server

记录freetds.log

知道我做错了什么吗？我尝试使用-p标志指定不同的端口，但总是得到相同的消息。我也尝试在freetds.log中输入一个条目：

[sqlserver]
host = 66.239.210.201
instance = MSSQLSERVER
tds version = auto

并将其与tsql -S sqlserver一起使用，这会产生与上述相同的错误文件。

感谢您的时间。

你的日志说

net.c：934：tds7_get_instance_port（66.239.210.201，[编辑]，1481）     net.c：985：tds7_get_instance_port：在尝试0的16时超时     ....     net.c：985：tds7_get_instance_port：在尝试15的16中超时     net.c：1057：实例端口为0

这意味着您的应用程序无法访问主机和端口对。可能有各种原因，如防火墙。或访问SQL服务器端提到的规则。

作为第一步，您可以尝试远程登录到主机和端口对以检查它是否可访问
