ИТ Блог. Администрирование серверов на основе ядра Linux
Iperf — это широко используемый инструмент для измерения пропускной способности сети или скорости. Это в основном используется для тестирования скорости проводной или беспроводной сети. Существуют две основные версии iperf, такие как iperf2 и iperf3. Давайте обсудим команду iperf3.
Чтобы узнать, установлен iperf3 или нет, мы можем использовать следующую команду в Linux:
$ iperf3
Если мы получим следующий вывод, это означает, что iperf3 не установлен:
The program “iperf3” is currently not installed. You can install it by typing: sudo apt install iperf3
Мы можем использовать следующую команду для установки iperf3:
$ sudo apt install iperf3
[sudo] password for rian: Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: libiperf0 ……. ……. Processing triggers for libc-bin (2.23-0ubuntu11) ...
Теперь снова введите «iperf3» в терминале.
$ iperf3
iperf3: parameter error - must either be a client (-c) or server (-s) Usage: iperf [-s|-c host] [options] iperf [-h|--help] [-v|--version] Server or Client: -p, --port # server port to listen on/connect to -f, --format [kmgKMG] format to report: Kbits, Mbits, KBytes, Mbytes ……………………… Many more lines.. ………………………
Команда TCP-сервера:
$ iperf3 -s ----------------------------------------------------------- Server listening on 5201 -----------------------------------------------------------
Команда клиента TCP: мы должны знать IP-адрес сервера.
iperf3 -c 192.168.1.102 -i1 -t20
Давайте посмотрим на вывод сервера и клиента:

Как мы видим, после 20-секундного запуска [-t20] сервер все еще работает, но клиент остановился.
Вот пропускная способность этого TCP-трафика:

Та же команда, что и для TCP-сервера.

Здесь мы изучили некоторые основные команды для iperf3. В iperf3 есть много расширенных опций. Чтобы узнать больше об iperf3, мы можем использовать команду «man iperf3» и использовать ее.
