Cory, Section 7.2.1 of the TLS spec (rfc2246) goes into detail about this, and Eric Rescorla's book has a complete discussion of what the issues are here. I believe you get the error from OpenSSL if you receive an TCP FIN *before* you receive a close_notify alert. The problem is probably in the peer which you perhaps cannot control. If you close down the SSL connection with SSL_shutdown(), you will cause a close_notify alert to be sent to the peer before the TCP FIN. Now, my question is: what does SSL_set_shutdown() do, how is it different from SSL_shutdown(), and what do the mode options SSL_SENT_SHUTDOWN and SSL_RECEIVED_SHUTDOWN do? _____________________________________ Greg Stark Ethentica, Inc.
