Looks like the server doesn't even get the Client hello message. Did you check the state of your client. Is it stuck in SSL_connect (it should be, I believe)? where is it stuck ? use s_client / s_server applications (comes with openssl.), if possible to figure out the issue. You may wish to use strace or like to figure out what calls your client/server make. This may hint towards the problem.
Let us know what you get, and we might be able to help you further. ~ Urjit ----- Original Message ----- From: "Jinsong Du" <[EMAIL PROTECTED]> To: <openssl-users@openssl.org> Sent: Friday, August 01, 2008 4:07 AM Subject: SSL3_accept makes Server stuck > (I sent the following post through Google Group, but it seems not appear on > the maillist) > > Hi all, > > I have a simple server using blocked socket and OpenSSL, its only > function is for user registering an account.
