在Ubuntu上通过TSQL无法连接到MSSQL

Question

我正在使用tsql确认与ms sql服务器实例的连接：

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

知道我在做什么错吗？ 我尝试使用-p标志指定不同的端口，但始终会收到相同的消息。 我也尝试在freetds.log中放置以下条目：

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

并将其与tsql -S sqlserver一起使用，这将导致与上述相同的错误文件。

谢谢你的时间。

您的日志说

net.c：934：tds7_get_instance_port（66.239.210.201，[已编辑]，1481）net.c：985：tds7_get_instance_port：在尝试16次0时超时.... net.c：985：tds7_get_instance_port：在尝试15次时超时16 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。 可能有诸如防火墙之类的各种原因。 或在SQL Server端提到的访问规则。

第一步，您可以尝试远程登录到主机和端口对，以检查其是否可访问
