Context

when the client suddenly shutdown in the test process. Such as nplug the network cable. The server always wating the client, can not start the next test process. Follow the manul from the website, try to add "--rcv-timeout" but can not find it as below info. please support, thank you in advance.

Bug Report

Enhancement Request

davidBar-On commented 4 weeks ago

Version 3.1.7 does not include --rcv-timeout option. It is available only from version 3.10.

Note that since version 3.16, there is a bug in --rcv-timeout and it does not work for values over 10 seconds. Therefore, if you install the newest version of iperf3, set --rcv-timeout up to 9 seconds, or use version 3.15.
