It is no longer updated, and contains much that is apocryphal, or at least wildly inaccurate.Telnet allows you to log into other computers. A lot of libraries, for example, still require you to “telnet” in to find the information you want. The Library of Congress is a good example. You can get to most MOOs and MUDs by telnet as well, if you haven’t got a specialized MUD client at hand.
When you telnet to a standard telnet site, such as locis.loc.gov (the Library of Congress), you have to use a telnet program (such as Better Telnet on the Macintosh, or just ‘telnet’ on Windows) and “Open” a “Session”, “Connection”, or “Remote Host”. The remote host you type is the name of the site you want to go to: locis.loc.gov, for example.
If you also need to type a port, and you don’t see a box to type the port number into, try just adding a space to the end of the hostname and type the port there: lambda.moo.mud.org 8888, for example.
- Terminal Emulation
- Occasionally, you’ll be asked what kind of “terminal emulation” you’re using. You’d better be using VT100 or one of its variants. If you’re given a list of options, choose the option that sounds most like “vt100”. If you are asked to type in the emulation, type “vt100”, in all lower case. This will usually work.
- An URL In Every Port?
- A lot of special telnet services are on different “ports”. A “port” is a hole in the host that allows data to get in and out. Each Internet service has a standard port that it uses. Telnet uses port 23. If the place you want to get to uses a different port, you need to let the telnet software know. Usually, there will be a box to type the port number into. If you don’t know the port number, leave this box blank. If you do know the port number, go…
