Raw sockets and SCTP ?

The system I am working on already has an SCTP stack implementation and it seems to fails to run on Solaris 10 because of what i think is a conflict between the local OS stack implementation and our own developed stack.

My problems stems from the fact that our custom SCTP implementation relies on opening a RAW socket with the IPPROTO_SCTP protocol. (This worked fine with Solaris 8)

Does anyone know if this is no longer allowed on Solaris 10 ?

I open the socket like:

socket(AF_INET, SOCK_RAW, IPPROTO_SCTP);

and then do a

sendto(...);

but everytime, the sendto() fails with "Cannot assign requested address" . This all worked on Solaris 8 with no problems, but i cannot get it working on Solaris 10.

Can anyone help ? Am I doing anything wrong, or have changes in Solaris 10 simply disallowed RAW sockets with protocol IPPROTO_SCTP (value = 132) ?

Thanks in advance!
