Hello developers,
There's been reports [1][2] that SCTP doesn't work on all platforms.
According to some random (but up to date) Solaris [3] and Linux [4]
documentation, it seems that the protocol identifier 'IPPROTO_SCTP'
should be used when creating SCTP sockets.
Before I made this change to sctp_server.c line 72 (in SVN trunk)
starting OpenSIPS with the 'fork' option configured failed and wrote
the following error to the log:
ERROR:core:sctp_server_init: socket: Protocol not supported [120]

- sock_info->socket = socket(AF2PF(addr->s.sa_family), SOCK_SEQPACKET, 0);
+ sock_info->socket = socket(AF2PF(addr->s.sa_family), SOCK_SEQPACKET,
IPPROTO_SCTP);
if (sock_info->socket==-1){
LM_ERR("socket: %s [%d]\n", strerror(errno), errno);
goto error;
By the way, I've withhold comments about the Kamailio posts to keep
this short. My guess is that the poster in [2] didn't check his
solution.
