Javascript Port Scanner

Of course, you must enable javascript to use this scanner.



With Microsoft Internet Explorer

ENTER

This system uses an xmlhttprequest object to launch a http request on a given host and port and waits a http response. With a little bit of javascript it's possible to make a scan on a range of ports or numeric dotted ip addresses . In addition you must tune the IE preferences :

  1. in IE options->advanced options-> disable native xmlhttp compatibility

  2. in IE options->security->internet->custom level-> allow data access for other domains

More Info

With all browsers, even IE

ENTER

There is another system that only detects hosts up or down with a timeout system. This system try to load an image from a given host and port but if it is not possible in a given time it shows a message, but I think this is worse and with a lot of false positives. It works in Firefox and IE, but I think only is useful to detect hosts up but not ports open or closed.
