Hi,

I have a program which is using DTLS blocking mode. And it works fine.
But I need to change it to non-blocking mode to port it to my
platform.

Can openssl DTLS support this?

I have tried to change the underlying sock to non-blocking mode. When
the SSL_connect is called, I can see using ethereal that the first
hello message were send out a lot of times. Is this normal behaviour?
or something wrong? When I only change the client to non-blocking, I
can connect to the server.

If I change both server and client to non-blocking, the server can
finish the handshake, but the client can not.

The one I am using is 0.9.8.a with the DTLS patch. But I have tried
the 0.9.8h, the result looks similar.

Thanks!

Yong
