While telnet pales in comparison to modern networking technology, it was revolutionary in 1969, and telnet helped pave the way for the eventual World Wide Web in 1989.

This remote login saved researchers hours of walking each semester.

In those original days of large mainframe computers, telnet enabled research students and professors to вЂlog inвЂ™ to the university mainframe from any terminal in the building.

Telnet is famous for being the original Internet when the Net first launched in 1969 and was built to be form of remote control to manage mainframe computers from distant terminals.

Telnet uses the port 23 and it was designed specifically for local area networks. Telnet is the joint abbreviation of Telecommunications and Networks and it is a networking protocol best known for UNIX platform.

To install the OpenSSH server application, and related support files, use this command at a terminal prompt: $sudo apt-get update To install it on your Ubuntu system, use this command at a terminal prompt: $sudo apt-get update Installation of the OpenSSH client and server applications is simpler. When using sshвЂ™s slogin (instead of rlogin) the entire login session, including transmission of password, is encrypted therefore it is almost impossible for an outsider to collect passwords.He or she cannot play back the traffic or hijack the connection when encryption is enabled. An attacker who has managed to take over a network can only force ssh to disconnect. SSH protects a network from attacks such as IP spoofing, IP source routing, and DNS spoofing.SSH is mostly used in all popular operating systems like Unix, Solaris, Red-Hat Linux, CentOS, Ubuntu etc. SSH also uses a public key for the authentication of users accessing a server and it is a great practice providing us extreme security.Once the data for communication is encrypted using SSH, it is extremely difficult to decrypt and read that data, so our passwords also become secure to travel on a public network.SSH is a very secure protocol because it shares and sends the information in encrypted form which provides confidentiality and security of the data over an un-secured network such as internet. SSH runs on port 22 by default however it can be easily changed.It provides strong authentication and secure communications over insecure channels.Network Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter).How DHCP server dynamically assigns IP address to a host?.Dynamic Host Configuration Protocol (DHCP).Asynchronous Transfer Mode (ATM) in Computer Network.What are the differences between HTTP, FTP, and SMTP?.File Transfer Protocol (FTP) in Application Layer.
