# rping.1

`rping` — RDMA CM 连接和 RDMA ping-pong 测试

## 名称

`rping`

## 概要

`rping -s [-v] [-V] [-d] [-P] [-a address] [-p port] [-C message_count] [-S message_size]`

`rping -c [-v] [-V] [-d] [-I address] -a address [-p port] [-C message_count] [-S message_size]`

## 描述

使用 librdmacm 在两个节点之间建立可靠的 RDMA 连接，可选地在节点之间执行 RDMA 传输，然后断开连接。

## 选项

**`-s`** 作为服务器运行。

**`-c`** 作为客户端运行。

**`-a`** `address` 在服务器上，指定绑定连接的网络地址。使用 IPv6 绑定到任意地址用 `-a ::0`。在客户端，指定要连接的服务器地址。

**`-I`** `address` 要绑定的地址，作为使用的源 IP 地址。如果在同一网络上有多个地址或复杂路由，这很有用。

**`-p`** 监听服务器的端口号。

**`-v`** 显示 ping 数据。

**`-V`** 验证 ping 数据。

**`-d`** 显示调试信息。

**`-C`** `message_count` 在每个连接上传输的消息数量。（默认无限）

**`-S`** `message_size` 每条传输消息的大小，以字节为单位。（默认 100）

**`-P`** 以持久模式运行服务器。这允许多个 `rping` 客户端连接到单个服务器实例。服务器将运行直到被杀死。

## 注意事项

由于此测试将 RDMA 资源映射到用户空间，用户必须确保拥有可用的系统资源和权限。详见 libibverbs README 文件。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man1/rping.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
