Internal Working

It works by calling a Java method from JavaScript and does not require user interaction. It doesn't always work on Firefox.

function do_scan(host, timeout) {
        var status=false;
        var ping="";

        try {
                status = java.net.InetAddress.getByName(host).isReachable(timeout);
        } catch (e) { /*handle exception...? */ }

        if (status) {
                ping = host + " is alive!";
        } else if (verbose) {
                ping = host + " is not alive";
        }
        return ping;
}

Feedback

• The default value (2000 ms) seems to be valid for virtual network
• Users should take care of the IP range format : 10.1.1.1-10.1.1.3 is valid, 10.1.1.1-3 is not
