What is the function of telnet?
Typically, this protocol is used to establish a connection to Transmission Control Protocol (TCP) port number 23, where a Telnet server application (telnetd) is listening. Telnet, however, predates TCP/IP and was originally run over Network Control Program (NCP) protocols.
Telnet is a simple, text-based network protocol that is used for accessing remote computers over TCP/IP networks like the Internet. Telnet was created and launched in 1969 and, historically speaking, you can say that it was the first Internet.
- To enable Telnet command line utilities:
- Click Start > Control Panel.
- Click Programs and Features.
- Click Turn Windows features on or off.
- In the Windows Features dialog box, check the Telnet Client check box.
- Click OK. The system installs the appropriate files. This will take a few seconds to a minute.
- SSH is a network protocol used to remotely access and manage a device. The key difference between Telnet and SSH is that SSH uses encryption, which means that all data transmitted over a network is secure from eavesdropping. Like Telnet, a user accessing a remote device must have an SSH client installed.
- Telnet is a protocol that allows you to connect to remote computers (called hosts) over a TCP/IP network (such as the internet). Using telnet client software on your computer, you can make a connection to a telnet server (i.e., the remote host).
