> Run below test case on Linux ppc with a user who's not administrator. (For Administrators, will test reachability by sending ICMP ECHO REQUESTs )
> import java.net.*;
> import java.util.*;
> public class Reachability {
> public static void main(String[] args) throws Exception {
> InetAddress ia = InetAddress.getByName("<IP_ADDRESS>");
> System.out.println("InetAddress: " + ia);
> Enumeration nis = NetworkInterface.getNetworkInterfaces();
> while (nis.hasMoreElements()) {
> NetworkInterface ni = (NetworkInterface) nis.nextElement();
> System.out.println("Network Interface: " + ni);
> boolean reachable = ia.isReachable(ni, 10, 60000);
> System.out.println(reachable);
> }
> }
> }
> The expected result is printing out at least one true.
> But when running this test case, it will print all false.
