computer. There are many versions of telnet
which
are freeware and widely distributed, as well as a few commercial
ones.
Start up telnet
. On some systems you can do this
from within Netscape (or another browser such as IE) by doing an "Open
Location" (under the "File" menu) and entering a URL of the form:
This should be a connection to the WWW server on www.latrobe.edu.au -- that is, you should be able to type "telnet://www.latrobe.edu.au:80
If that doesn't work, try typing "
telnet
" at a DOS prompt, or if you're on a Mac, do a "Find File" for "telnet
" and double click it. Once you've gottelnet
up and running, select the "Open Connection" menu item and enter: "www.latrobe.edu.au 80
" (without the quote marks). This should pop up a "terminal" (command line) window containing nothing at all. At this point it might be useful to look for a "Preferences" option to turn on "Local Echo", so you can see what you're typing. Some versions oftelnet
are clever enough to do this where appropriate, others have to be told...

The object of this prac exercise, incidentally, is twofold:
If it doesn't, it may not be your fault anyway -- one of the more recent technologies that can block access is a firewall, so if you're connected to an Internet Provider outside La Trobe University, this could be what's happening. We'll see later how the protocol works when firewalls are in use.
