TEST PROCEDURE

        "confirmPing" confirms the availability of NUT for variable size of
        PING.
        
         TN                     NUT
         |                       |
        -+-----------------------+-

        1.
        TN send Echo Request size=64.  
        
         === echo request(64) ===>

        2.
        NUT send Echo Reply size=64.
        << JUDGMENT 1 >>
        <=== echo reply(64) ===

        3.
        TN send Echo Request size=1280.  
        
         === echo request(1280) ===>

        4.
        NUT send Echo Reply size=1280.
        << JUDGMENT 2 >>
        <=== echo reply(1280) ===

        5.
        TN send Echo Request size=1500.  
        
         === echo request(1500) ===>

        6.
        NUT send Echo Reply size=1500.
        << JUDGMENT 3 >>
        <=== echo reply(1500) ===


JUDGMENT

        << JUDGMENT 1 -PASS- >>
                "PASS" means that NUT received the ICMP Echo Request 
                size=64Byte, and NUT can send ICMP Echo Reply size=64Byte.

        << JUDGMENT 2 -PASS- >>
                "PASS" means that NUT received the ICMP Echo Request 
                size=1280Byte, and NUT can send ICMP Echo Reply size=1280Byte.

        << JUDGMENT 3 -PASS- >>
                "PASS" means that NUT received the ICMP Echo Request 
                size=1500Byte, and NUT can send ICMP Echo Reply size=1500Byte.
