tcpdump和tcpdump_dp和tcpdumpdp之间的区别

tcpdump、tcpdump_dp和tcpdumpdp是三个不同的概念，它们之间存在一些区别。

1. tcpdump：tcpdump是一个常用的网络抓包工具，用于捕获和分析网络数据包。它可以在命令行下运行，并提供丰富的过滤和解析功能，用于检查网络流量、排查网络问题等。tcpdump可以在大多数操作系统上使用。

2. tcpdump_dp：tcpdump_dp是指基于Data Plane Development Kit（DPDK）的tcpdump版本。DPDK是一个开源软件包，旨在提高数据平面应用程序的数据包处理性能。tcpdump_dp使用DPDK库来加速数据包的捕获和处理，以提供更高的性能和效率。

3. tcpdumpdp：tcpdumpdp并不是一个已知的概念或软件名称。可能是你自己提到的一个特定的实现或变种，但它不是广泛被使用或公认的。

综上所述，tcpdump是常见的网络抓包工具，tcpdump_dp是基于DPDK的tcpdump版本，而tcpdumpdp可能是一个自定义的概念或特定实现，没有明确的定义或说明。

tcpdump servaddr.sin_addr.s_addr=htonl()

This command is incomplete and does not make sense. It appears to be an attempt to use the tcpdump command to capture network traffic based on the source or destination IP address, but it is missing important information such as the interface to capture on and the protocol to filter on. The use of htonl() suggests that the command may be attempting to convert the IP address to network byte order, but it is not clear what IP address is being used or why it needs to be converted. More information is needed to provide a complete and accurate answer.

tcpdump servaddr.sin_addr.s_addr=htonl(8080)

This command is not valid.

"servaddr.sin_addr.s_addr=htonl(8080)" is not a valid filter expression for tcpdump.

If you want to capture traffic on port 8080, you can use the following command:

tcpdump port 8080

This will capture all traffic that is sent to or from port 8080.
