Telnet began as one of the basic features of Unix, and at Brand X we use telnet from a central console to access and configure the various Brand X computers. We use the basic text version of Telnet, which is built into Berkely Unix. There are Mac and Windows versions of Telnet, which you can run from home, and which give you all of the features of Unix Telnet, but with a nifty graphical window. Once you've got a connection started, all of the various forms of Telnet are the same because what you really see is whatever the other computer is sending you, and telnet is always going to be text no matter which version of telnet you use. Telnet is easy and it is popular. It is well worth learning. If you enjoy the Internet, Telnet will become one of your most useful and frequently used tools.
Software and information about NCSA Telnet for Mac can be obtained from http://www.ncsa.uiuc.edu/SDG/Software/Brochure/Overview/MacTelnet.overview.html
Some computers may also request a "port number". Put this after the name. Enter the host address in the Host/Session Name box. Click OK.
Example: if you want to connect to the Realms game, you need to connect to port 1501 at realms.dorsai.org :
Name: Realms Dungeon Game Host Address: realms.dorsai.org 1501
Once you have got the host typed in, click on "connect". NCSA Telnet will try to set up a connection for you. If it is successful, it will bring up a terminal window and you can log in to the remote computer and start your Telnet Session.
There are a couple of ways of saving the connection information so you don't have to type it in every time you log in (useful if you keep going back to the same places.)
Once you have established a connection with a particular host, you may choose to save the configuration information. From the File menu, choose Save Set, and the characteristics of that session will be saved to a file. You may have several different saved session files, so be sure to give them a name that will indicate their purpose. For example, you might name the above sessions "Realms Dungeon Game."
Or, you can create a "session" which will be saved, sort of like a bookmark. From the Edit menu, choose Preferences/Sessions. Choose New. A dialog box will open that lets you specify the connection characteristics for a ew session. Enter the host name for the service you want to connect to as well as an alias (a short descriptive title for the session you are creating). For example, you could open a session to www.brandx.net with an alias of "Brand X Web Server."
NCSA is generally pretty reliable. The most frequent problem is that your telephone connection may be interrupted, and Telnet will stall. This usually means that you were never logged in, or you had an incoming call which caused your Internet connection to die, or it may mean that you didn't do anything for a very long time (more than ten minutes) and the server disconnected you (this is called a "time-out".) Sometimes you will find that the server you are logging into is down. This happens even to the largest of servers. This week (Aug 1 1996) both Yahoo and USC have been down. It is unfortunate but it happens.
Here is a sample of how to start a telnet session at Brand X internet. (You will see pretty much the same thing if you had connected with a program such as NCSA Telnet.)

To telnet to brandx.net, open QVT Telnet and click on the icon that looks like a computer with a blue screen. It's a little bit abstract, they don't win big points for art on this one. A box will come up with the title "Start Terminal Session". Enter for the host:
Name: Reals Dungeon Game Network Address: reals.dorsai.org Port: 1501
If you are connected to the system, then QVT will connect and you will soon see the login prompt for the remote machine.
Starting a Telnet sesssion with Ewan is easy. From the File menu select "New". This will bring up the address window. "Name" is what you would like to call the connection you are going to create. Network address or host name is the computer you want to connect to. Port is the port number, if the computer you are connecting to requires one. You could put for example:
Name: Reals Dungeon Game Network Address: realms.dorsai.org Port (Custom): 1501
Both Windows Telnet programs are generally pretty reliable. The most frequent problem is that your telephone connection may be interrupted, and Telnet will stall.
