[Seagull-users] SCTP diameter support on Ubuntu

[Hans H. <hho...@cr...>]

Hello All -

I'm running into a challenge using Seagull, with SCTP support, on Ubuntu 11.10 server with kernel-3.0.0.13.

I've been able to compile seagull 1.8.2, with SCTP library sctplib-1.0.10.  It took some source code mods to comply with the new 4.6 rev of gcc. But ... whatever ... that's no big deal.

However, when trying to execute Seagull with SCTP support, I get the following message:
root@coden-lcne01:/home/diameter-env/run# ./start_s6a_client.ksh
ERROR: Kernel SCTP seems to be available! You cannout use sctplib and kernel SCTP simultaneously!
Aborted

Well, now, ain't that special.  Off I went to rebuild my kernel without SCTP.  And that's where I ran into problems.

I've tried to rebuild the kernel without SCTP built-in, since there doesn't seem to be any kernel-level SCTP support built into seagull.  However, the DLM kernel module (Dynamic Lock Manager) requires SCTP support, and I can't remove that.  I've been told to switch over to Fedora - but I don't see why that would help - as I would imagine that the base filesystem drivers (like the DLM module) would be the same across Linux variants.  But I'm hardly an expert at that.  Before I go down the road of a reinstall, I would like some assurance that this will work.

Has anyone been able to get SCTP support working with Ubuntu 11.04?  Suggestions?

Some details on my rig:
root@coden-lcne01:/# uname -a
Linux coden-lcne01 3.0.0-13-server #22-Ubuntu SMP Wed Nov 2 15:09:08 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

root@coden-lcne01:/# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 11.10
Release:        11.10
Codename:       oneiric

Also, the client.conf.xml code:

...
<define entity="transport"
    name="sctp-trans-1"
    file="libtrans_extsctp.so"
    create_function="create_cipsctpio_instance"
    delete_function="delete_cipsctpio_instance"
    init-args="type=tcp">
  </define>
...

Thanks,
