Hello,
I have two doubts. Give someone advice.


1. The following error message is output.
"sctp_initLibrary: could not open raw socket for SCTP. You
must have root provileges !"

Whether or not only the root to can execute an application,
when SCTPlib is used?

2. I am not able to execute the plural application.
When it tries to establish the association with the 2nd
application abort is done.

Two applications are using the port number that differs
mutually.

I am doing an application build by linking SCTPlib.
The sctpd(daemon) is not executed.
Is this method wrong?


Best regards
