QOTD (Quote Of The Day) is an application layer protocol. Quote of the Day is a simple protocol which can deliver daily quotes. The protocol is defined by RFC 865. According to the RFC, a QOTD server is run on port 17 for TCP and UDP connections. This protocol was assigned to TCP/UDP port 17. It allows a client to get a random quote from a server. The quotes are maintained at a reasonable length by specifying a maximum length of 512 characters for the quote.
