Counting TCP retransmissions
提问by M10TheMist
I would like to know if there is a way to count the number of TCP retransmissions that occurred in a flow, in LINUX. Either on the client side or the server side.
我想知道在 LINUX 中是否有一种方法可以计算流中发生的 TCP 重传次数。无论是在客户端还是服务器端。

You can see TCP retransmissions for a single TCP flow using Wireshark. The "follow TCP stream" filter will allow you to see a single TCP stream. And the tcp.analysis.retransmissionone will show retransmissions.
您可以使用 Wireshark 查看单个 TCP 流的 TCP 重传。“跟随 TCP 流”过滤器将允许您查看单个 TCP 流。而tcp.analysis.retransmission一个会显示重传。

Looks like netstat -ssolves my purpose.
看起来netstat -s解决了我的目的。
