Anybody knows a 'Your Computer Information' script?

I would like to create a page where the users can view their own computer info.

thanks in advance

Do you mean like IP, browser, etc?

Something like this? http://www.catpin.com/cgi-bin/user.pl

That script is a Perl script (cgi-bin) ... you'll see that script
attached below. Called "userinfo.txt" because I can't attach
a file with the extension ".cgi"

There might be some PHP ones available too.
