    There is a hash of IP #s that point to a client. If two clients have
    the same IP # then one will mask the other. A client is just an identifing
    string.

    It does not really matter to me how the IP are displayed. I may make it
    selectable. I do think that if IP #s are displayed as HEX there must be a
    standard. As all IP #s are displayed in net order now. It would be hard
    to have nfs's in host order is /proc/net stays in net order.

    I do hope that the output will be compatable with the xtab file.
