sctp_test - Send and receive messages via SCTP

sctp_test -H -P -h -p -l|s


This is a userspace test application for the SCTP Linux kernel reference implementation.

Act as client
Listen for connections (server)
assoc_pattern in the mixed mode 0 = sequential ascending(default) 1 = random
0 = none 1 = min(default) 2 = max
0 = 1 byte packets. 1 = 1352 byte packets.
(fragmentation point for an i/f with 1500 as mtu.) 2 = 1353 byte packets.
(min. size at which fragmentation occurs
for an i/f with 1500 as mtu.) 3 = Sequence of 1, 1353, 32768 byte packets. 4 = Sequence of following size packets.
(1, 1000, 2000, 3000, 5000, 10000,15000, 20000, 25000, 32768) 5 = 32768 byte packets.
(default max receive window size.) 6 = random size packets.
Packets of specifed size.
