About: QOTD

An Entity of Type: person, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Quote of the Day (QOTD) service is a member of the Internet protocol suite, defined in RFC 865. As indicated there, the QOTD concept predated the specification, when QOTD was used by mainframe sysadmins to broadcast a daily quote on request by a user. It was then formally codified both for prior purposes as well as for testing and measurement purposes. A host may connect to a server that supports the QOTD protocol, on either TCP or UDP port 17. To keep the quotes at a reasonable length, RFC 865 specifies a maximum of 512 octets for the quote.

dbo:abstract
  • Quote of the Day (abreviado QOTD, Cita del día) es un servicio perteneciente a la familia de protocolos de Internet, definido en el RFC 865. Como se indica allí, el concepto de QOTD Antecede a la especificación, cuando QOTD era usado por los administradores de los mainframes para difundir por la red la cita del día en respuesta a un usuario. Fue entonces formalmente codificado tanto para propósitos prioritarios como para propósitos de testeo y mantenimiento, definidos en el RFC 865. Un host puede conectarse a un servidor que soporte el protocolo QOTD, por el puerto 17 de TCP o UDP. Para mantener las citas en una longitud razonable, el estándar define una longitud máxima de 512 caracteres por cita. Aunque algunas fuentes indican que el servicio QOTD es raramente habilitado, y casi siempre para evitar los ataques 'pingpong',​ El interés continúa en el propósito preexistente de servir citas como se puede ver con los motores de búsquedas. El mantenimiento y análisis actual de las redes IP es más comúnmente hecho con herramientas como ping y traceroute, las cuales son adaptaciones más robustas del protocolo echo. Se han hecho diversas implementaciones a este protocolo, en GitHUb hay un repositorio con implementaciones de QOTD escritas en 6 lenguajes distintos: hay implementaciones en Python 3, Java, C++, Haskell, Scala y Node.js.​ (es)

To keep the quotes at a reasonable length, RFC 865 specifies a maximum of 512 octets for the quote. Although some sources indicate that the QOTD service is rarely enabled, and is in any case often firewalled to avoid 'pingpong' attacks, interest continues in the pre-existing purpose of serving quotes as can be seen with web engine searches. Current testing and measurement of IP networks is more commonly done with ping and traceroute, which are more robust adaptations of the echo protocol (RFC 862), which predated the attempt at QOTD standardization.

  • O serviço Quote Of The Day (Citação do Dia, em inglês) ou QOTD é um Protocolo de Internet definido em RFC 865. Sua utilização é para propósitos de testes e medidas. Um host pode conectar-se a um servidor que suporta o protocolo QOTD, na porta 17, tanto TCP ou UDP. O servidor então retorna uma mensagem curta arbitrária. Esta era tradicionalmente uma seleção aleatória de uma lista de citações notáveis. O serviço QOTD raramente é habilitado, e em qualquer caso geralmente é bloqueado pelo firewall para evitar ataques 'pingpong'. Atualmente, testes e medição de redes IP é mais comumente feito com ping e traceroute. (pt)
  • 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, а тестирование и измерение параметров компьютерных сетей чаще всего проводится с помощью утилит ping и traceroute.
