then, start ncat listening on server:
ip netns exec ls1p2 ncat --sctp -l 80 -k >> sctp.log&

and client:
ip netns exec ls1p1 ncat --sctp -l 80 -k >> sctp.log&

then, from ls1p4 start sctp ncat,
 ip netns exec ls1p4 ncat --sctp 192.168.173.254 8000 <<< s
Ncat: Connection refused.


Actual results:
sctp  connection fail.

Expected results:
sctp LB work.


Additional info:
tried tcp and udp, work normally.
