http://www.gnucitizen.org/projects/javascript-address-info http://f-box.org/~dan/jstest.html The following technique was brought to me by DanBUK (http://f-box.org/~dan/). Dan managed to find the internal IP address of the visiting client by establishing a socket between local host and the remote web server. Upon success the socket populates its structure with all kinds of useful information among some of which are the internal IP address and the hostname. http://www.gnucitizen.org/projects/javascript-address-info/addressinfo.js This technique requires Java, however I think that It should be possible to achieve similar result by invoking special ActionScript methods from Flash. POC can be found on the url above. -- pdp (architect) http://www.gnucitizen.org ------------------------------------------------------------------------- Sponsored by: WatchfireWatchfire was recently named the worldwide market leader in Web application security assessment tools by both Gartner and IDC.
