That's just might be how they get them in the first place. If you buddy
downloaded the file and then contacted google.com there are chances that
his browser sent the previous URL visited [0]. If it was added in google's
database maybe somebody found this after a web search (although the fact
that the referer is empty points that this might not be the case).

Just my 2c.

[0] is this a FUD? I believe google uses this as part of his spidering
process, I'm also not sure if the browser would provide this information,
though.

at least netscape only sends a referer if i used a link.
when i enter an url, e.g. www.google.de after downloading a file, google
doesn't know which site i visited before.

what about the easiest questions:
- did you used ssl or do you trust all the providers between your friend
and your server?
- do you trust your friend?
- do you trust the knowledge of your friend, e.g. that he has no
trojaner on his client?
- do you trust all the software your friend installed? google toolbar,
internet explorer itself,

Ralf

Now there was one access with a referrer pointing to some kind of 
database containing links to movie downloads (yes, the large file I 
mentioned was a trailer). Along with the link there was the info that 
the link came from an irc channel in irc (quakenet).

So the mysterie is partly resolved (regarding the fact where all those 
people came from). What still remains is the question how the first 
person found the file there...

 [0] is this a FUD? I believe google uses this as part of his spidering

 though.

It would provide this information in the referrer, this is how I found 
the link database. :)

Right, that was one aspect that I forgot.

 - did you used ssl or do you trust all the providers between your friend
 and your server?

No SSL, but I don't trust any provider in between. In fact most of the 
accesses came from the same provider that was used by the friend, which 
is no magic because it is one of the largest providers here in germany 
(I guess you have heard of T-Online before, right? :)).

 - do you trust your friend?

Yes.

 - do you trust the knowledge of your friend, e.g. that he has no
 trojaner on his client?

This was the first idea that came to my mind. He is still checking that 
part.

 - do you trust all the software your friend installed? google toolbar,
 internet explorer itself, 

I'm not sure what software he has installed, but that would be another 
thing to have a look at. Thanks for the tip.

 The story behind that question: I put a large file on the webserver that 
 was intended for download for a friend. The only one I told about this 
 file was this friend, and he said he didn't tell anyone about it. 
 Nevertheless since yesterday there have been some requests for this file

Are you using the VirtualHost capability on this server?
If so, you should be aware of using some _default_:* entry to catch
all access not using (or using a bad) hostname for VirtualHost.

If someone access to your server using an undefined VirtualHost,
it will arrive on the default configuration of your web server.
And if this default configuration doesn't have an Indexes directive,
it will be able to list every directories files...!

 But I'm curious how they found out about it... any ideas?

I just tried to forge a http request targetting at a non-specified 
domain name that resolved to the correct ip. The result was that the 
root directory's index.html was shown. So I think this is not the problem.
