Hi

It's me replying myself.
That is the easiest solution for me... Thanks.

The problem lied in the fact that I wasn't calling "listen(fd, 1)" before trying to listen in the socket.

On the other hand, as you could have seen in the trace I sent, after SCTP1 sents an INIT, SCTP2 replies with an INIT ACK, instead of an ABORT (as it is prescribed in section 3.1 of Sockets API Extensions for SCTP )

I believe that it is a BUG. I tested with linux kernel sctp and that implementation does reply with an ABORT message if the user forgets to call 'listedn(fd, 1)'
Yes, this is the behaviour of an kernel implementation. The problem lies in the fact that we the have an SCTP implementation
independent from the socket layer implementation. We did not implement an additional feature to the sctplib just to
get that behaviour in the socket layer... Sorry for any inconvenience.

Best Regards
Javier Acuña
