Looks like it needs a BIO_free_all(bio) or something similair. -----Original Message----- From: owner-openssl-us...@openssl.org [mailto:owner-openssl-us...@openssl.org]on Behalf Of Matthew Allen Sent: Wednesday, April 21, 2010 5:18 AM To: openssl-users@openssl.org Subject: Socket left in CLOSE_WAIT state...
Hi, My code leaves sockets in the CLOSE_WAIT state after I free the SSL connection (running on windows XP with OpenSSL 0.9.8e). After I'm done with the connection I call SSL_shutdown and SSL_free, but that doesn't close the socket on the client side. My code's probably wrong, so tell me what I should change? #include <stdlib.h> #include "windows.h" #include "openssl/ssl.h" char Hostname[] = "imap.gmail.com"; int Port = 993; int main(int args, char **arg) { printf("OpenSSL Test\n"); SSL_library_init(); SSL_load_error_strings(); ERR_load_BIO_strings(); OpenSSL_add_all_algorithms(); SSL_CTX *Ctx = SSL_CTX_new(SSLv23_client_method()); if (Ctx) { SSL *Ssl = 0; BIO *Bio = BIO_new_ssl_connect(Ctx); if (Bio) { BIO_get_ssl(Bio, &Ssl); if (Ssl) { SSL_set_mode(Ssl, SSL_MODE_AUTO_RETRY); BIO_set_conn_hostname(Bio, Hostname); BIO_set_conn_int_port(Bio, &Port); if (BIO_do_connect(Bio) > 0) { printf("Connected to '%s' using SSL\n", Hostname); char Data[256]; char *Cmd = "A0001 CAPABILITY\r\n"; int w = SSL_write(Ssl, Cmd, strlen(Cmd)); if (w > 0) { printf("Wrote %i bytes.\n", w); int r = SSL_read(Ssl, Data, sizeof(Data)); if (r > 0) { printf("Got %i bytes.\n", r); } else printf("SSL_read failed.\n"); } else printf("SSL_write failed.\n"); } else printf("BIO_do_connect failed.\n"); } else printf("BIO_get_ssl failed.\n"); } else printf("BIO_new_ssl_connect failed.\n"); if (Ssl) { SSL_shutdown(Ssl); SSL_free(Ssl); } /* At this point I expect the socket should have disappeared, but it's still there hanging around in CLOSE_WAIT... why? */ SSL_CTX_free(Ctx); } return 0; } Thanks -- Matthew Allen ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
