sure you can:
telnet <ip of your provider> 80
GET / HTTP/1.1
Host: <name of your vhost>
That's it. It should spit out the text.
Of course an easiyer way would be to just enter the ip and hostname in your
/etc/hosts file and browse to it. But that would be boring wouldn't it?
The path is usually the
hosts-file under Linux under Windows it is here (sorry it has multiple locations depending on the Windows version).
I can't comment on where you find telnet. Usually it is within the command Prompt which should be reachable from the start menu (I haven't used Windows in years so forgive my lack of detailed memory how telnet on windows works)
