I'm using Fedora 17 64-bit version, with Linux kernel version 3.3.4-5.fc17.x86_64.

I installed lksctp using yum.

sudo yum install lksctp-tools.x86_64

When I try to run 

sctp_status -H 127.0.0.1 -P 10 -l

I'm getting this result:

Starting tests...


        *** socket: failed to create socket:  Protocol not supported ***

How can I resolve this problem? Why can't I start an SCTP server this way?

Is the sctp module loaded (sudo modprobe sctp). What does checksctp say?

checksctp says checksctp: Protocol not supported subo modprobe sctp FATAL: Module sctp not found. but I when i try sudo modprobe xt_sctp it loads the driver dont know what that is. – Isuru Sep 5 '12 at 4:38
xt_sctp is for the ability of netfilter (iptables) to recognize SCTP traffic. Maybe your sctp module is called something else, or maybe it's not compiled at all, or maybe it's available as a different package (maybe because it's all kernel). Does sudo modprobe net_pf_2_proto_132 work? grep SCTP /boot/config* – Stephane Chazelas Sep 6 '12 at 8:04

I gave the command:

% yum install lksctp-tools-3.3.4-5.fc17.i686 \
    lksctp-tools-devel-3.3.4-5.fc17.i686 \
    kernel-3.3.4-5.fc17.i686 \
    kernel-modules-extra-3.3.4-5.fc17.i686

Everything is installed but still checksetup is giving same error, "protocol not supported".

modprobe sctp.ko or modprobe sctp (without extension) also gives errors:

FATAL: Module sctp.ko not found

and

FATAL: Module sctp not found
