Quote of the Day Protocol

Communication Protocols and Standards

The Quote of the Day (QOTD) service is an Internet protocol suite member defined by Jon Postel in RFC 865 in 1983. Its concept originated with mainframe system administrators who broadcast a daily quote in response to user requests. QOTD supports connections through TCP or UDP port 17, with quotes limited to 512 octets. The service is rarely enabled and is often firewalled because of denial-of-service attack concerns.
