How do I detect leechers?

[Iron-Monkey]

I have noticed that my site has used up MUCH more bandwidth than usual and I am afraid that my files are being leeched by other site.

How can I detect which files are being leeched (linked off another site or forum)? And how do I detect WHERE it is being leeched from (from which URL)?

Is there a function in the Cpanel that let me find out?

Thanks for the help.

Have you looked it up in the web stats or the server log ?

Web stats will give you a general overview of the traffic.

You can also use the Raw Access Logs, it will allow you to download a file which contains every request your server has fullfilled.

Look in your logs and see how much bandwidth is being taken up by file type. If you see an inordinate amount of bandwidth taken up by images, it may be that your site has gotten its images indexed by Google. You can exclude images from Google's search bot by creating a "robots.txt" file in your public_html folder which has this in it:

User-agent: Mediapartners-Google*
Disallow: 

User-agent: googlebot
Disallow: *.cgi
Disallow: *.jpg
Disallow: *.gif
Disallow: *.bmp

User-agent: *
Disallow: /templates/
Disallow: /photopost/
Disallow: /images/
Disallow: /Logos/
Disallow: /cgi-bin/

I've excluded the file extensions noted from indexing by googlebot, and then complete folders from ANY bot out there as noted.

Also, Cpanel has a way to activate Hot Link Protection by file type in case an individual web site owner is hotlinking to your site. Look for the Hot Link Protection icon (in the X skin, its in the lower right.) You do have to know which file types are being leached.
