You find something called rpcsvchost while to see what’s running on your Mac. What is this process, and should you be worried? In a word, no: rpcsvhost is a core part of macOS.

在查看Mac上正在运行的内容时，您会找到一个名为rpcsvchost的东西。 这是什么过程，您应该担心吗？ 总之，没有：rpcsvhost是macOS的核心部分。

Today’s process, rpcsvchost, is a tool used to connect with certain kinds of networks, particularly Microsoft ones. To quote the man page for rpcsvchost:

当今的过程rpcsvchost是用于连接某些类型的网络(尤其是Microsoft网络)的工具。 引用rpcsvchost的手册页：

rpcsvchost is a very simple environment for hosting DCE/RPC services. It loads DCE/RPC services from the list of plugins given as arguments, binds to an appropriate set of endpoints and listens for protocol requests.

rpcsvchost是用于托管DCE / RPC服务的非常简单的环境。 它从作为参数给出的插件列表中加载DCE / RPC服务，绑定到一组适当的端点并侦听协议请求。

So now we know this is a process that helps coordinate networking, but that doesn’t clarify things because we don’t know what DCE/RPC is. It turns out this stands for Distributed Computing Environment / Remote Procedure Calls.

因此，现在我们知道这是一个有助于协调网络的过程，但是由于我们不知道什么是DCE / RPC，因此无法澄清问题。 事实证明，这代表了分布式计算环境/远程过程调用。

All sorts of network services use DCE/RPC, perhaps most notably Microsoft Exchange. Apple added DCE/RPC support back in 2010 as part of Mac OS X Lion 10.7. Apple’s implementation of DCE/RPC is available , which is where Apple hosts the source code for its open source projects.

各种网络服务都使用DCE / RPC ，也许最著名的是Microsoft Exchange。 苹果在2010年作为Mac OS X Lion 10.7的一部分添加了DCE / RPC支持。 Apple的DCE / RPC实施可找到是Apple托管其开源项目的源代码的地方。

DCE/RPC is an implementation of the Remote Procedure Call technology developed by the Open Group as part of the Distributed Computing Environment. DCE/RPC is most commonly used to interact with Windows network services.

DCE / RPC是Open Group在分布式计算环境中开发的远程过程调用技术的实现。 DCE / RPC最常用于与Windows网络服务进行交互。

Apple provides a for the truly curious, but for the most part, all you need to know is that rpcsvchost enables your Mac to connect with certain kinds of networks.

Apple为真正好奇的人提供了，但在大多数情况下，您需要知道的是rpcsvchost可使Mac与某些类型的网络连接。

If rpcsvchost is using up a lot of CPU power, you might be having trouble connecting to a Microsoft Exchange server, or some other networking service that uses DCE/RPC. If this is the case, those apps are probably also using a lot of CPU power, so them and see if that helps.

如果rpcsvchost消耗了大量CPU资源，则可能无法连接到Microsoft Exchange服务器或其他使用DCE / RPC的网络服务。 如果是这种情况，则这些应用程序可能还使用了大量CPU能力，因此请它们，看看是否有帮助。

It’s also possible, though not probable that a piece of malware is using DCE/RPC to phone home. , just in case.

也有可能，尽管不太可能是某个恶意软件正在使用DCE / RPC来回拨电话。 以防万一，这是。
