telnet
" on your 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 by doing an "Open Location" (under the "File" menu) and entering
a URL of the form (from memory):
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
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.
GET /Index.html
" in the window
and get a pile of HTML sent back to you.The window will probably disappear immediately (it's usually a "Preferences" option to have them stick around after close), but you'll have seen the protocol in action.
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.
