Network News Transfer Protocol (NNTP)

Network News Transfer Protocol (NNTP)

The Network News Transfer Protocol (NNTP) is the TCP/IP protocol used to access Usenet news servers. Usenet news servers contain thousands of individual message boards known as
newsgroups. Each newsgroup is about a particular subject (cars, dating, computers, etc.). Chances are, if you have an interest, there is a newsgroup about it. The details of the NNTP protocol
are specified in RFC 977.

Note:

Because of the relative complexity involved in configuring a news reader program,
there are many websites (including google.com) that have made newsgroup
access available through the Web.

Secure File Transfer Protocol (SFTP)

Secure File Transfer Protocol (SFTP)

Secure File Transfer Protocol (SFTP) is used when you need to transfer files over an encrypted connection. It uses an SSH session (more on this later) which encrypts the connection. The SFTP
protocol then is used to transfer files over this encrypted connection. Apart from that, it functions exactly as the FTP protocol does: It is used to transfer files between computers.

Trivial File Transfer Protocol (TFTP)

Trivial File Transfer Protocol (TFTP)

Trivial File Transfer Protocol (TFTP) is a “stripped down” version of FTP, primarily used to boot diskless workstations and to transfer boot images to and from routers. It uses a reduced feature set (fewer commands and a smaller overall program size). In addition to its reduced size, it also uses UDP instead of TCP, which makes for faster transfers but with no reliability.

File Transfer Protocol (FTP)

File Transfer Protocol (FTP)

File Transfer Protocol (FTP) provides a mechanism for single or multiple file transfers between computer systems; when written in lowercase as “ftp,” it is also the name of the client software used to access the FTP server running on the remote host. The FTP package provides all the tools needed to look at files and directories, change to other directories, and transfer text and binary files from one system to another. FTP uses TCP to actually move the files.

Note:

We’ll look at how to transfer files using FTP in detail in the next chapter.

Simple Network Management Protocol (SNMP)

Simple Network Management Protocol (SNMP)

Simple Network Management Protocol (SNMP) allows network administrators to collect information about the network. It is a communications protocol for collecting information about
devices on the network, including hubs, routers, and bridges. Each piece of information to be collected about a device is defined in a Management Information Base (MIB). SNMP uses UDP
to send and receive messages on the network.
