  2. 1TCP Port Service Multiplexer (TCPMUX) • The TCP Port Service Multiplexer (TCPMUX) is a little-used Internet protocol defined in RFC 1078, this is a multicelular service.
  3. 5Remote Job Entry (RJE) • Remote job entry is the procedure for sending requests for data processing tasks or 'jobs' to mainframe computers from remote workstations, and by extension the process of receiving the output from such tasks at a remote workstation
  4. 7ECHO • The Echo Protocol is a service in the Internet Protocol Suite defined in RFC 862. It was originally proposed for testing and measurement of round-trip times.
  5. 18Message Send Protocol (MSP • The Message Send Protocol (MSP), more precisely referred to as Message Send Protocol 2, is an application layer protocol used to send a short message between nodes on a network.
  6. 20FTP -- Data • Is used to transfer data to other objects/electronics.
  7. 21FTP -- Control • Transfer protocol.
  8. 22SSH Remote Login Protocol • Secure Shell, or SSH, is a cryptographic (encrypted) network protocol to allow remote login and other network services to operate securely over an unsecured network.
  9. 23Telnet • Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminalconnection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP).
  10. 25Simple Mail Transfer Protocol (SMTP) • Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (email) transmission. First defined by RFC 821in 1982, it was last updated in 2008 with the Extended SMTP additions by RFC 5321— which is the protocol in widespread use today.
  11. 29MSG ICP • UDP Port 29 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
  12. 37Time • The Time Protocol is a network protocol in the Internet Protocol Suite defined in 1983 in RFC 868 by Jon Postel and K. Harrenstein. Its purpose is to provide a site-independent, machine readable date and time.
  13. 42Host Name Server (Nameserv) • the ARPA Host Name Server Protocol (NAMESERVER[1]), is an obsolete network protocol used in translating a host name to an Internet address
  14. 43WhoIs • This article is about a method for checking information about ownership of a domain name. For an IRC command called WHOIS
  15. 49Login Host Protocol (Login) • Terminal Access Controller Access-Control System (TACACS, usually pronounced like tack- axe) refers to a family of related protocols handling remote authentication and related services for networked access control through a centralized server. The original TACACS protocol, which dates back to 1984, was used for communicating with an authentication server, common in older UNIX networks; it spawned related protocols:
  16. 53Domain Name System (DNS) • The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates domain names, which can be easily memorized by humans, to the numerical IP addresses needed for the purpose of computer services and devices worldwide. The Domain Name System is an essential component of the functionality of most Internet services because it is the Internet's primary directory service.
  17. 69Trivial File Transfer Protocol (TFTP) • Trivial File Transfer Protocol (TFTP) is a simple, lock-step, File Transfer Protocol which allows a client to get from or put a file onto a remote host. One of its primary uses is in the early stages of nodes booting from a local area network. TFTP has been used for this application because it is very simple to implement.
  18. 70Gopher Services • The Gopher protocol /ˈɡoʊfər/ is a TCP/IP application layer protocol designed for distributing, searching, and retrieving documents over the Internet. The Gopher protocol was strongly oriented towards a menu-document design and presented an alternative to theWorld Wide Web in its early stages, but ultimately HTTP became the dominant protocol. The Gopher ecosystem is often regarded as the effective predecessor of the World Wide Web.
  19. Finger protocol • In computer networking, the Name/Finger protocol and the Finger user information protocol are simple network protocols for the exchange of human-oriented status and user information.
  20. 80HTTP • in Internet — TCP port 80, most often used by Hypertext Transfer Protocol
  21. 103X.400 Standard • X.400 is a suite of ITU-T Recommendations that define standards for Data Communication Networks for Message Handling Systems (MHS) — more commonly known as email.
