[lxc-users] sctp protocol in container of LXC/docker

[Fajar A. Nugraha]

Works for me

precise / # sctp_test -H 0 -P 250 -l
local:addr=0.0.0.0, port=250, family=2
seed = 1417170515

Starting tests...
socket(SOCK_SEQPACKET, IPPROTO_SCTP)  ->  sk=3
bind(sk=3, [a:0.0.0.0,p:250])  --  attempt 1/10
listen(sk=3,backlog=100)
Server: Receiving packets.
recvmsg(sk=3) ^C


This is ubuntu precise container on trusty host, kernel 3.13.0-37-generic.
I'm guessing you simply need to upgrade your kernel, or use a newer distro
for your host. Since it looks like you use rhel/centos6, trying
http://elrepo.org/tiki/kernel-ml should be the least-effort way to test it.
