In your program fragment, there are no buffers given:
  msg->msg_iov = NULL;
  msg->msg_iovlen = 0;

This causes ext_sendmsg_singlebuffer() to skip the call to
SCTPSocket::sendTo():
if((msg != NULL) && (msg->msg_iov != NULL) && (msg->msg_iov->iov_base !=
NULL)) {

For the next version, I will fix this problem.


Try the following:
char buf;
struct iovec iov = { (char*)&buf, 0 };
...
msg->msg_iov = &iov;
msg->msg_iovlen = 1;

In sctpsocket.cc, the lines from about 44 to 58 consist of "#define
PRINT_..." which are commented out. Uncomment all these lines and you will
get debug messages about the AutoConnect-Status. You should now see a message
"AutoConnect: Shutdown of outgoing association A<assocID>..." if it works.


Please mail me whether or not this change solves the problem. If it does not
solve the problem, please mail me the source of your program and instructions
how to use it. Then, I can look for the error.


Best regards
