Версия

-   iperf3-3.14-alt1

Дистрибутивы

-   ALT Workstation 10.1 i586, обновленный до Sisyphus

Шаги воспроизведения

Команда hostname -i показывает текущий адрес машины. Машина выступает в
качестве и сервера, и клиента.

Установить пакеты:

    # apt-get install -y iperf3 libiperf3-0 net-tools

Запустить сервер (убедившись, что iperf3 не запущен):

    # killall iperf3 &> /dev/null ||:
    # iperf3 --server --daemon --pidfile /root/iperf3.pid --logfile /root/iperf3.log

Запустить UDP-трафик:

    # iperf3 --client $(hostname -i) --parallel 5 --reverse --udp

Ожидаемый результат: в итоговой таблице присутствует sender (нормальный
Lost/Total) и на клиенте, и на сервере.

Фактический результат: в итоговой таблице отсутствует sender (вывод
клиента)
