NCSA Telnet Telnet is a remote login application. It allows you to connect to another machine on the Internet if you have a login account on that machine. When connected, you can use the services there just as if you were sitting at the console of that computer.
Some services allow telnet access without an account.
These are restricted accesses which won't allow you full use of the remote computer. These services normally require a port number after the machine name to identify the specific service you are requesting. To use telnet, you must enter either the host name, or its numeric IP address, followed by a port number if it is required. Enter one space between the host and port number. This is your default.
