tinytdsを使ってRails 3.2のUbuntu VMからSQL Serverに接続する

Question

私は、VirtualBoxでUbuntu 11.10のvmを実行しているWindows 7マシンを持っています。私のWindows 7マシンには、SQL Server 2008がインストールされています。これは、レール3.2とtiny_tds gemを使用して私のUbuntu VMからアクセスしようとしています。

私は私のRailsアプリケーションを起動しようとすると、私は、次を得る：

私は、SQL Serverがポート1433上で私のホストIPへのtelnetを実行して、VMにアクセス可能であると私はにできる午前ことを確認することができます私はルビーやTinyTds経由で接続することはできません。私のVM用ネットワークアダプタはNATを使用しています。さらに、Windowsマシンから同じレールアプリケーションを実行すると、SQL Serverに接続できます。 SQL ServerではTCP/IP接続が有効になっています。

代わりにdataserverの設定をhostに変更して修正しました。
