[sctp-dev] java.net.SocketException: Protocol not available

[Amit Bhayani]

Some more insight, I was able to connect the client socket from my machine
to remote machine when it had SCTP server socket open.

If remote server sokcet is down I get this error. In wireshark trace I see
that my machine does send INT but there is no response what so ever.

Shouldn't it complain that connection refused instead of protocol not
supported?

Amit.
