Just for fun, try saving the program below as "MacAddresses.java" and
compile/run it on your system:

    % javac MacAddresses.java
    % java MacAddresses

If you don't have "javac" on your system, you'll need to do a :

    % pfexec pkg install SUNWj6dev

Not to say that the Cisco Clean Agent uses this method to grab MAC
addresses (it should), but this will verify that your JVM is working
properly on your OpenSolaris system.

My output is similiar to this:

  Interface: vboxnet0
    -- MAC address = Not available
  Interface: e1000g0
    -- MAC address = MAC address = 00 14 4F 28 2E F2 
  Interface: lo0
    -- MAC address = Not available

            while (interfaces.hasMoreElements()) {
                NetworkInterface nif = interfaces.nextElement();

                String name = nif.getDisplayName();
                byte[] macAddress = nif.getHardwareAddress();

                System.out.println("Interface: " + name);
                System.out.print("  -- MAC address = ");
                if (macAddress != null) {
                    for (byte x: macAddress)
