This sounds like a bug with the > TCP model.. I rewrote netcat's readwrite() to use select() instead of the poll() systemcall but read() on the network file descriptor still does not return EOF. So netcat is not notified that the SCTP association has been closed. > So to recreate this.. I set things up run it > and ctl-c the client? Yeah. Starting SCTP server: $ nc -c -l 127.0.0.1 55555 Starting SCTP client: $ nc -c 127.0.0.1 55555 Now send a SIGINT (ctl-c) to client or server. Sending SIGINT using TCP sockets will terminate the connection immediately and notifing the other side.
