Is SO_REUSEADDR option available for SCTP?

Is SO_REUSEADDR option available for SCTP?

[Sun Paul]

Hi

we have running in trouble in bind the port when the SCTP application
is stopped and then started, we got the "Address already in use".

we would like to know whether SO_REUSEADDR option available for SCTP?

if yes, is it also available for the java socket API?

Thanks

RBK

Yes it is available for SCTP protocol sockets.

Don't know.  It would have to be something supported in Java.

It has the same limitation as usage with TCP sockets.  Only 1 listening socket
is allowed, but you can bind multiple sockets with different addresses to the
same port.

Which kernel version are you using?  What is the behavior that you are observing?
