2016-06-30 In the early times of the internet, a bunch of very basic, yet useful protocols were defined. These protocols are bound to low port numbers. - RFC 862: echo protocol (port 7) [0] - RFC 863: discard protocol (port 9) [1] - RFC 864: text generator protocol (port 19) [2] - RFC 865: quote of the day protocol (port 17) [3] - RFC 866: active users protocol (port 11) [4] - RFC 867: daytime protocol (port 13) [5] - RFC 868: time protocol (port 37) [6] These RFCs are useful for RFC writing: - RFC 2119: Keywords in RFCs [7] - RFC 7322: RFC style guide [8] There are several humorous and informative RFCs: - RFC 1121: Poems [9] - RFC 1882: The twelve days before Christmas [10] - RFC 1925: The twelve networking truths [11] - RFC 1462 and RFC 1935: What is the Internet? [12] [13] - RFC 1855: Netiquette [14] - RFC 3092: The etymology of ``foo'' [15] And a lot of April Fool's Day RFCs in the recent years.
