Telnet is an Internet tool that lets users connect to remote hosts from another computer, such as a mainframe, minicomputer, or local networked workstation.
Some remote sites have guest facilities that permit connecting without having a local account.
In other cases you may need a computer account for the remote computer, with a username and password, before you can log onto it. If connecting as a guest, the remote site may prefer that you use the computer during non-peak hours, or they may restrict access during times of peak activities. Be courteous in observing local usage conventions. The site name for the CSUN HP Unix system is csun1.csun.edu or csun2.csun.edu, as an example. When you connect and logon to a remote site the screen display may vary slightly, depending on the kind of computer and local implementation of the Telnet protocol.
