我正在尝试连接到 CentOS 5.8 上的 SQL Server 2008。我正在使用 unixODBC 2.3.0 和 SQL Server ODBC 驱动程序 (www.microsoft.com/en-us/download/details.aspx?id=28160)。
当我尝试通过运行测试连接时:
isql -v mydsn username password
它给了我:
[S1T00][unixODBC][Microsoft][SQL Server Native Client 11.0]Login timeout expired
[08001][unixODBC][Microsoft][SQL Server Native Client 11.0]A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.
[08001][unixODBC][Microsoft][SQL Server Native Client 11.0]TCP Provider: Error code 0x2726
[ISQL]ERROR: Could not SQLConnect
端口是开放的,服务器是可访问的。
我试图进一步诊断问题,但被困在这里:

显然,建立连接时出现了问题。
谁能帮我?如果您需要任何其他信息,请告诉我。
谢谢
