I'm new to sockets programming and OpenSSL so I'm expecting this to be a mistake on my part.
Most the time I'm able to setup basic SSL comms without a problem, pretty much following the code in the OpenSSL book. However I've been running some tests with a lot of repeated open/closing of connections and every now and then the call to BIO_do_connect fails (returns -1). This wouldn't be a problem, just try the connection again, but I find that retries will fail for about the next minute, even if I restart both the server and client apps in this test setup.
I must be missing out some connection closing/flushing or something. Or is it that too many connections in a short time frame overwhelms Window's networking system in some way, locking it out for a minute.
SSL_error_string gives "error:02002740:system library:connect:reason(1856)"
Sample client code: // Connect m_BIO = BIO_new_connect("127.0.0.1:7777"); BIO_do_connect(m_BIO); // Returns -1 m_SSL = SSL_new(ctx); SSL_set_bio(m_SSL, m_BIO, m_BIO); SSL_connect(m_SSL);
// Do stuff...
// Disconnect, am I missing anything? if(SSL_get_shutdown(m_SSL) & SSL_RECEIVED_SHUTDOWN) SSL_shutdown(m_SSL); else SSL_clear(m_SSL); SSL_free(m_SSL);
This behaviour happens on WinXP and Win2K PCs, using OpenSSL 0.9.7c all compiled with VC++ 7.1.
