On SERVER side:
lksctp-tools-1.0.11src/apps/sctp_xconnect -H local_ip -P local port -l
On CLIENT side:
lksctp-tools-1.0.11src/apps/sctp_xconnect -H local_ip -P local port -h server ip -p server port -c -a
Use -a option to send packet actively.
After a while(depends on your memory capacity), CLIENT exit unexpectedly.
