Quote of the day

Quote of the day

Quote Of The Day (сокращенно QOTD) — это сетевой протокол, определённый в RFC 865. Он предназначен для тестирования и измерительных целей.

Клиент устанавливает соединение с сервером, поддерживающим протокол QOTD, через порт 17, используя TCP или UDP. Сервер возвращает произвольное короткое сообщение. Обычно оно выбиралось случайным образом из списка известных цитат.

В настоящее время служба QOTD не активирована на большинстве серверов и часто фильтруется для защиты от DoS-атак[1], а тестирование и измерение параметров компьютерных сетей в чаще всего проводится с помощью утилит ping и traceroute.
