<p class="m_-7702628345476798945gmail_msg">I am not sure what ESTABLISHED is meant by netstat for UDP
sockets, because there is no connection defined for UDP (datagram
socket is kind of shoot and forget) -- maybe it track that there
was some traffic and remembers that for a while. Perhaps reading
the manual of netstat will help to understand better.</p>
