FreeBSD + unixODBC + FreeTDS 上出现“未知主机名称。”

FreeBSD + unixODBC + FreeTDS 上出现“未知主机名称。”

我从 FreeBSD 10.1 服务器连接到 Microsoft SQL Server 2012 时遇到了一些问题。

我通过 ports 安装了 FreeTDS 和 unixODBC。我编译了支持 unixODBC 的 FreeTDS。这是我的 freetds.conf：

[server1]
  host = 192.168.100.147
  port = 1433
  tds version = 7.2

调用 tsql 工作正常。

但是当我尝试使用“osql”或“isql”通过 odbc 连接时，连接失败并出现以下错误：

looking up hostname for ip address 192.168.100.147

Configuration looks OK.  Connection details:

                   DSN:    server1
              odbc.ini:    /usr/local/etc/odbc.ini
                Driver:    /usr/local/lib/libtdsodbc.so
       Server hostname:    sqlsrv01
               Address:    192.168.100.147

Attempting connection as sa ...

[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[01000][unixODBC][FreeTDS][SQL Server]Unknown host machine name.
[ISQL]ERROR: Could not SQLConnect

这是我的 odbc.ini 的内容：

[server1]
  Driver = FreeTDS
  Servername = server1

这是我的 odbcinst.ini：

[FreeTDS]
  Driver = /usr/local/lib/libtdsodbc.so
  Client Charset = UTF-8
  UsageCount = 1

我阅读了几篇关于使用精确命名信息 odbc.ini 和 freetds.conf 的帖子，但连接仍然失败。

有人可以帮忙吗？

我现在能够回答我自己的问题了。

遵循 unixODBC 邮件列表的提示1我援引

odbcinst -i -s -f /usr/local/etc/odbc.ini

现在我可以通过 osql 连接到服务器。
