what is TELNET

Telnet is a protocol that allows you to connect to remote computers (called hosts) over a TCP/IP network (such as the Internet). TELNET is a general two-way communication protocol that can be used to connect to another host and run applications on that host remotely.Using telnet client software on your computer, you can make a connection to a telnet server (i.e., the remote host). Once your telnet client establishes a connection to the remote host, your client becomes a virtual terminal, allowing you to communicate with the remote host from your computer. In most cases, you'll need to log into the remote host, which requires that you have an account on that system. Occasionally, you can log in as guest or public without having an account.

           The telnet commands allow you to communicate with a remote computer that is using the Telnet protocol. You can run telnet without parameters in order to enter the telnet context, indicated by the Telnet prompt (telnet>). From the Telnet prompt, use the following commands to manage a computer running Telnet Client.

The tlntadmn commands allow you to remotely manage a computer running Telnet Server. These commands are run from the command prompt. Used without parameters, tlntadmn displays local server settings.
