Hi Pumipat,

you might want to read section

7.1.16. Set/clear IPv4 mapped addresses (SCTP_I_WANT_MAPPED_V4_ADDR)

This socket option is a boolean flag which turns on or off mapped V4
addresses. If this option is turned on and the socket is type
PF_INET6, then IPv4 addresses will be mapped to V6 representation.
If this option is turned off, then no mapping will be done of V4
addresses and a user will receive both PF_INET6 and PF_INET type
addresses on the socket.

By default this option is turned on and expects an integer to be
passed where non-zero turns on the option and zero turns off the
option.

Best regards
Michael

Dear Michael,

As you said that the handling of the mixing between ipv4 and ipv6 might be different, could you please explain more about that or tell me where I can find the information about that?

Best regards,

Pumipat

On Linux you can send by address anytime. If there is no association,
there will be
one established for you, if there is one, that wil be used. This is
the same way it
is handled in *BSD.

Thank you for you answers

However I still have a question on one-many model on Linux. The one-
many model on Solaris you explained to me is what I understand.
Could you please tell me how it works in Linux?

Best regards,

Pumipat

Hi Pumipat,

the basic difference is that
- Solaris implements an older version of the ID, so you might not
want to use
the newest functions. Habe a look at netinet/sctp.h to find which
functions
are provided.
- The one1many model is different on Solaris. You can send by address
only to
setup an association. Lateron, you must send by associd.
- The handling of mixtures of IPv4 and IPv6 addresses might be
different.

Best regards
Michael
