You can see what they see using telnet (which incidentally suggests you
can use a PHP script that opens a socket connection on port 80 to get
the information). The commands in telnet are as follows:

telnet www.interjinn.com 80
HEAD / HTTP/1.0
<enter>

That will give you the OS, web server, and any PHP information. The
uptime I believe is determined by making these queries at various
intervals.

HTH,
