[SR-Users] mhomed opened sockets

Hello,

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.

Cheers,
Daniel
