Dear Forum,
I am using Centos-5.6 in VirtualBox uner Windows7.
I have installed it several times using different combinations (linux text, linux vesa=1024x768), with /without Gnome Desktop, using Development Tools and Libraries, Graphics Internet etc..
I found that one or two installations show that sctp can be loaded via modprobe, otherwise I get Protocol family not supported when I use lksctp-tools.
I have used in fresh installations:
1. firewall enabled, SELinux=Permissive
2. yum install lksctp-tools
3. locate sctp.ko (gives presence output)
3. modprobe sctp
4. /usr/bin/checksctp
I am working on SS7 project.
Help will be greatly appreciated.

.. this will have no bearing on the issue other than the number of dependencies that will need to be installed when you do 'yum install lksctp-tools'. The sctp module is included in the kernel so locating it is not really relevant
Dear,
there are some improvements, let me tell first.
I updated
/etc/sysconfig/network with IPV6=yes
/etc/sysconfig/network-script/ifcfg-eth0 with IPV6INIT=yes, IPV6AUTOCONF=yes
/etc/modprobe.conf with on in the relevant protol alias lines.
..
now I can modprobe sctp fine.
After installing lksctp-tools via yum,
I get /usr/bin/checksctp, sctp_test etc.
./checksctp gives:
SCTP supported
when I use sctp_test -H192.168.56.2 -P 3565 -h 192.168.56.1 -p 3565 -s
I get error:
Surely, there will be two signaling points (SIGTRAN)
but at this moment I am unable to transmit anything over SCTP via LKSCTP.
my kernel 2.6.18-238 has built in SCTP support, verified by /usr/bin/checksctp utility
Hope you got it working if not and for anyone else who is facing the same issue.
I had the same issue every time I tried to do the test I got the same error. What I did was I downgraded the lksctp version to lksctp-tools-1.0.6-3.el5 and it worked perfectly I think there is a version conflict between the kernel and the new lksctp version or you could try to upgrade the kernel version
Dear jasondevj
Thank you very very much, you solved my very old problem that i put under the large heap.
You may be right, it is some problem with version.
any way lksctp-tools-1.0.6-3.el5 is working as far as checksctp is working in client/server configuration.
I will inform as i go for SS7-sigtran testing using lksctp.

Masood
