连接到远程服务器上的狮身人面像

我最近把sphinx移到了和我们的db相同的服务器上，所以我们的架构是：

1. 托pipe我们的Web应用程序的文件服务器
2. 具有Sphinx实例的数据库服务器（searchd）

当我尝试连接到sphinx在ip.to.db.server我得到以下错误：

Sphinx response connection to ip.to.db.server:9312 failed (errno=113, msg=No route to host)

有什么特别的我需要做的，使端口9312访问我的networking应用程序？

• 远程软件在Windows 8及更高版本上安装
• 运行远程命令来保存debian软件包列表
• 需要什么权限才能使用服务帐户远程运行服务器上的PowerShell？
• 在远程计算机上使用PowerShell导入PowerShell脚本证书？
• 如何使用445以外的不同端口使用“net use”连接到远程服务器

当前TCP端口LISTEN ing：

 tcp 0 0 0.0.0.0:9306 0.0.0.0:* LISTEN 23496/searchd tcp 0 0 0.0.0.0:9312 0.0.0.0:* LISTEN 23496/searchd 

iptables -L输出：

到目前为止，我已经做了很多search，没有运气。 任何帮助深表感谢。
