IRC USER讯息对我来说毫无意义 [英] IRC USER message makes no sense to me

问题描述

首先，请告诉我是否不允许在这里询问此协议……这似乎是最好的地方.对不起，如果我错了.

First, please tell me if I'm not allowed to ask about this protocol here... It just seemed like the best place. Sorry if I'm wrong.

因此，根据维基百科，USER消息如下所示:

So according to wikipedia the USER message goes like the following:

USER username hostname servername :realname

主机名和服务器名有什么区别?谢谢.

What's the difference between hostname and servername? Thanks.

推荐答案

RFC 1459 4.1.3节中的状态:

RFC 1459 states in section 4.1.3:

请注意，当USER命令来自直接连接的客户端时，IRC服务器通常会忽略主机名和服务器名(出于安全原因)，但是它们用于服务器到服务器的通信.

Note that hostname and servername are normally ignored by the IRC server when the USER command comes from a directly connected client (for security reasons), but they are used in server to server communication.
